Catalog ACZ-4

Introduction The ACZ family of air-cooled scroll condensing units offers a wide selection of units from 10 to 155 tons. The ACZ-A series has capacities from 10 to 39 tons with a single refrigerant circuit using a set of tandem scroll compressors. The ACZ-B series has capacities from 30 to 155 tons with dual refrigerant circuits with either two or three scroll compressors in each of two circuits. The ACZ series of air-cooled scroll condensing units continues McQuay’s legacy of high quality, high efficiency, latest technology and quiet operation. These features make the ACZ family the best overall value in air-cooled condensing units available today. Efficient Operation The ACZ units utilize R22 to meet the efficiency requirements of ASHRAE 90.1. With either two or three scroll compressors for each of two refrigerant circuits, excellent part load performance is achieved.

Latest Control Technology These units have the latest control technology through utilization of McQuay’s new MicroTech II™ microprocessor. Integrating with your building automation system is easy with the Protocol Selectability™ feature using LONMARK®, BACnet® or Modbus® network communication, requiring only the addition of a small communication module to the unit controller.

Compact Size Our reputation for compact designs with small footprints to minimize space requirements continues to be a primary feature. Quiet Operation The ACZ units further enhance McQuay’s reputation for low operating sound levels to make these condensing units “neighborhood friendly”.

Features and Benefits ACZ-A, Single Circuit, 10 to 39 Tons Great values also come in small packages. The ACZ-A units have a single refrigerant circuit with capacities from 10 to 39 tons. Customer benefits include high efficiency operation, low sound levels, scroll compressor technology and MicroTech II™ controls.

High Efficiency Operation The ACZ-A units operate at high efficiency with IPLVs up to 14.5 EER. Through the use of tandem scroll compressors and the latest control technology, excellent part load performance occurs.

Quiet Operation ACZ-A units have low sound ratings through the use of scroll compressors. These compressors are housed in a sheet metal enclosure to further reduce the levels. All units have a sound power rating of 90 dBA or less.

Superior Control With MicroTech II™ The MicroTech II™ controller is provided on the ACZ-A models providing control strategies expected of much larger condensing units.

Building Automation System Integration The MicroTech II™ controller allows for easy BAS integration through our Protocol Selectability™ feature using LONMARK, BACnet or Modbus communications. This is another advanced feature typical of larger condensing units. Figure 2, Model ACZ 033, 30 ton Condensing Unit

ACZ-B Condensing Units, Dual Circuits, 30 to 155 Tons The ACZ-B units with dual refrigerant circuits from 30 to 155 tons offer outstanding benefits that make this product effect for a variety of applications. High Efficiency Full Load Operation ŸŸLower Energy Costs For High Loads Utilizing the new scroll compressor technology, the ACZ-B condensing units have high full load efficiency. All system components are selected for optimum performance including the large condenser coil areas and compressors. Full load EERs range up to 12.3 at ARI Standard Conditions (45°F saturated suction temperature, 95°F ambient temperature, sea level).

Excellent Part Load PerformanceŸŸLower Energy Costs for Most for the Year By using either four or six compressors on each condensing unit, unloading characteristics and part load performance are outstanding. The IPLV part load values for our scroll units range up to 14.6 EER. Integrated part load value (IPLV) is a part load performance indicator as outlined in ARI Standard 365. The IPLV rating compares the performance of different condensing units under identical conditions. When the IPLV is listed in EER (Energy Efficiency Ratio), a higher EER will indicate that the chiller’s overall performance is better.

Compact Design with Small FootprintŸŸInstallation Flexibility and Lower Cost Again, McQuay ACZ-B series condensing units have a reputation for a compact design and small footprint. A small footprint can save installation costs by minimizing the size of the concrete mounting pad or reduces the amount of structural steel if the unit is mounted on the roof.

Quiet Operation -- “Neighborhood friendly”ŸŸInstallation Flexibility The ACZ condensing units are designed with quiet scroll compressors. Fans are selected for good performance and lower sound levels. The attention to detail with sound in mind is critical in the design. Paying attention to small issues such as refrigerant piping, s for piping, and securing component to the structure are all important to making a quiet product. We proudly publish our sound performance.

Superior Controls -- MicroTech II™ ŸŸEfficient, Reliable Operation Once again, McQuay has provided the latest technology in controlling the ACZ-B condensing units. The new MicroTech II™ controller provides a “ friendly” environment for the operator. The control logic is designed to provide maximum efficiency, to help provide continuing operation in unusual operating conditions through proactive controls and to provide a history of conditions to aid in problem resolutions. Perhaps the greatest benefit is Protocol Selectability™ for integrating the unit with your building automation system (BAS). MicroTech II™ allows interfacing into the BAS directly through LONTALK®, BACnet® or Modbus®. See the complete control description on page 7 in this catalog.

Design Features The McQuay ACZ Air-Cooled Condensing Unit is a product of the McQuay commitment to offer quiet, reliable, energy efficient equipment. An approach incorporating high quality compressors, state-of-the-art coil design, and innovative packaging. Construction Factory assembled and mounted on a heavy-gauge steel channel base. The base rails, s and cabinetry are powder-coat painted. The base distributes the unit weight for roof loading. Varied and convenient installation is possible by virtue of the unit's small footprint.

Compressors Copeland’s Compliant Scroll™ tandem or triple compressors are used. These rugged hermetic compressors are constructed with an integral cast iron frame, cast iron scrolls, three Teflon impregnated bearings, and three oil filtration devices for each compressor. Using Copeland's Compliant Scroll tandem compressors provides two, four or six steps of capacity modulation depending on unit model size. One compressor can run alone, depending on the load of the system, resulting in excellent part-load efficiency. Each refrigerant circuit has specially designed oil and gas equalization lines to control oil migration. The design also offers radial and axial compliance (no tip seals), a large internal volume for liquid handling, a removable suction screen, and a rotary dirt trap and oil screen. In addition, the compressor is self-compensating for wear, handles liquid and debris, and inherently yields the highest efficiency for its class. This well protected compressor includes a solid-state motor protection module, 4 individual motorwinding sensors, a patented internal discharge temperature probe, and a patented shutdown feature that prevents reverse rotation. An internal discharge check valve helps prevent shutdown noise and comes standard with high and low pressure taps with Schrader valves, a sight glass, an oil level adjustment valve, and an off cycle crankcase heater. Units are available in 60 Hertz electrical voltage configurations from 208 to 575 volt operating at 3500 rpm.

Condenser Coils Condenser coils have internally enhanced seamless copper tubes arranged in a staggered row pattern. The coils are mechanically expanded into McQuay lanced and rippled aluminum fins with full fin collars. A variety of optional coil material and coatings are available for corrosive atmospheres. An integral subcooler circuit provides subcooling to greatly reduce the possibility of liquid flashing. The external condenser coils are fitted with a protective wire mesh guard as standard equipment.

Condenser Fans and Motors Multiple direct drive dynamically balanced propeller fans operate in formed venturi openings at low tip speeds for maximum efficiency and minimum noise and vibration. A heavy-gauge vinylcoated fan guard protects each fan. Each condenser fan motor is heavy-duty, 3-phase, Totally Enclosed Air Over (TEAO) with permanently lubricated ball bearings and inherent overload protection. SpeedTrol option includes a single-phase motor with fan speed control on the lead fan for each circuit.

Control System The MicroTech II™ advanced DDC unit controller sures all other microprocessorbased unit control systems available today. This powerful, -friendly control system provides the flexibility and performance needed for either stand-alone unit operation or the controller can be easily tied into your building automation system of choice using McQuay’s exclusive Protocol Selectability™ feature. Protocol Selectability™ allows you to choose from open standard protocols such as BACnet®, Modbus®, and LONTALK® to communicate easily with the Building Automation System that best meets your facility requirements. These optional communications modules are available factory-installed or can be easily field installed. MicroTech II™’s state-of-the-art design will not only permit the unit to run more efficiently, but will also simplify troubleshooting if a system failure occurs. Every MicroTech II controller is programmed and tested prior to shipment to help provide a trouble-free startup.

Operator-friendly The MicroTech II control menu structure is separated into four distinct categories that provide the operator or service technician with a full description of current unit status, control parameters, and alarms. Security protection helps prevent unauthorized changing of the setpoints and control parameters. MicroTech II continuously performs self-diagnostic checks, pressures and protection devices, monitoring system temperatures, and it will automatically shutdown a compressor, a refrigerant circuit or the entire unit if a fault occurs. The cause of the shutdown will be retained in memory and can be easily displayed in plain English or metric units for operator review. The MicroTech II unit controller can also retain and display the time the fault occurred and the operating conditions that were present at the time of the fault, which is an extremely useful feature for troubleshooting. In addition to displaying alarm diagnostics, the MicroTech II controller also provides the operator with a warning of pre-alarm conditions. Alarm notification data can also be ed to your BAS through an optional communications module.

Selection Procedure ACZ condensing units are selected in conjunction with some kind of evaporator equipment. The ACZ ratings are based on saturated suction temperature at the compressor inlet and on ambient air dry-bulb temperature. For a system selection, the ACZ condensing unit is usually selected first, then the line loss added to the condensing unit saturated suction temperature to determine the saturated evaporating temperature. This temperature is then used for the selection of the evaporator, whether it is a DX coil or shell and tube heat exchanger. The pipe size can be determined from procedures and data in the Refrigerant Piping Section. For selection purposes, the tubing size is based on a pressure equivalent of a two-degree F line loss (equal to about 3-psi pressure drop). The correction for altitude found in Table 1 is applied, if applicable, by dividing the required job capacity by the correction factor to ascertain the necessary unit capacity in the Capacity Tables. ACZ performance is found in Table 2 through Table 8 (I-P and SI) covering the normal range of saturated suction temperatures and ambient air temperatures.

Selection example, Inch-Pound units Given: Dual refrigeration circuits are required 400 Mbh job requirement 95°F ambient temperature 40°F saturated suction temperature 2,000 foot altitude 1. Correct for altitude by dividing the required capacity by the correction factor found in Table 1. 400 Mbh required / 0.986 factor = 406 mbh corrected requirement. 2. From Table 3, ACZ 030B through 065B, an ACZ 040 at the given conditions will produce 410 Mbh with a unit power input of 41.3 kW and a unit EER of 9.9. 3. Correct for altitude: Capacity: 410 Mbh x 0.986 = 404 Mbh Power: 41.3 kW x 1.009 = 41.7 kW EER: 9.9 EER x 0.986/1.009 = 9.7 EER 4. An evaporator would be selected at 42°F saturated evaporating temperature.

Selection example-SI units Use the same procedure as for Inch-Pounds but use SI tables and units.

Application Adjustment Factors Altitude Correction Factors Performance tables are based at sea level. Elevations other than sea level affect the performance of the unit. The decreased air density will reduce condenser capacity consequently reducing the unit's performance. Table 1, Altitude Correction Factors

Sound levels can be as important as unit cost and efficiency, and must be addressed before the start of any development program. Efforts by McQuay Design Engineers to design units that are sensitive to the sound requirements of the market, combined with inherently quiet scroll compressors, have paid off.

Background Information Sound is a vibration in an elastic medium and is essentially a pressure and particle displacement phenomena. A vibrating body produces compression waves, and as the waves are emitted from the vibrating body, molecules are ultimately compressed. These values are transmitted through gas, liquid, solid⎯anything which is elastic or viscous. The sound data provided in this section is presented with both sound pressure and sound power levels. Sound power is the total sound energy radiated by a source per unit of time integrated over the surface through which the sound is radiated. Sound power is a calculated quantity and cannot be measured directly like sound pressure. Sound power is not dependent on the surrounding environment or distance from the source, as is sound pressure. Sound pressure varies with the distance from the source and is dependent on its surroundings. For example, a brick wall located 10 feet from a unit will affect the sound pressure measurements differently than a brick wall at 20 feet. Sound pressure is measured in decibels (dB), which is a dimensionless ratio (on a logarithmic scale) between measured sound pressure and a reference sound pressure level.

Sound Pressure Levels - Full Load All sound pressure tables give the overall "A" weighted sound pressure levels which are considered typical of what can be measured in a free field with a hand held sound meter, in the absence of any nearby reflective surfaces. The sound pressure levels are measured at 30 feet (10 meters) from the side of the unit at 100% unit load and ARI conditions. 95°F (35°C) ambient air temperature and 50°F suction temperature.

Sound Power Levels Acoustical consultants can require sound power octave band data to perform a detailed acoustical analysis. The tables present sound power levels per ARI Standard 370, “Sound Rating of Large Outdoor Refrigerating and Air Conditioning Equipment”. These standards were developed to establish uniform methods of determining the sound power radiated by large outdoor and indoor equipment. The aforementioned methods are based on providing sound power levels by octave band and the overall ‘A’ weighted value. Measurements are taken over a prescribed area around the unit and the data is mathematically calculated to give the sound power, dB. Sound power can be thought of as basic sound level emanating from the unit without consideration of distance or obstructions.

Sound Reduction due to Distance from the Unit The distance between a source of sound and the location of the sound measurement plays an important role in minimizing sound problems. The equation below can be used to calculate the sound pressure level at any distance if the sound power is known. Results for typical distances are tabulated in Table 13. Another way of determining the effect of distance is to work from sound pressure only. “Q”, the directionality factor, is a dimensionless number that compensates for the type of sound reflection from the source. For example, a unit sitting on a flat roof or ground with no other reflective surfaces or attenuation due to grass, snow, etc., between source and receiver: Q=2.

Sound pressure can be calculated at any distance from the unit if the sound power is known. Lp=Lw-(20 log r) + (10 log Q) - .5 Lp = sound pressure

r = distance from unit in feet

Lw = sound power

Q = directionality factor

With Q=1, Unit suspended in space (theoretical condition), the equation simplifies to: Lp = Lw – (20)(log r) –0.5 With Q=2, for a unit sitting on a flat roof or ground with no adjacent vertical wall as a reflective surface, the equation simplifies to: Lp = Lw – (20)(log r) + 2.5 With Q=4 for a unit sitting on a flat roof or ground with one adjacent vertical wall as a reflective surface, the equation simplifies to: Lp = Lw – (20)(log r) + 5.5 The equations are reduced to table form in Table 13 for various distances and the two most usual cases of “Q” type of location.

Sound Pressure Reduction - Low Ambient Conditions Unit operation at a lower ambient temperature than 95°F (35°C) will also result in lower sound pressure levels. The sound pressure level will decrease 1 dBA for ambient temperatures between 85°F and 94°F (29.4°C and 34.4°C), 2 dBA for ambient temperatures between 75°F and 84°F (23.9°C and 28.9°C), and 3 dBA for ambient temperatures between 65°F and 74°F (18.3°C and 23.3°C).

Electrical Data, General There are many installations where the expected summer ambient air temperatures will be at 105°F (40.1°C) or less, resulting in smaller unit electrical requirements compared to operation at 106°F (41.1°C) and above. In these lower temperature cases, there can be considerable installation cost savings by using smaller and more appropriate electrical service. Single circuit models, ACZ-A, are rated to 115°F (46°C) as standard. There is no High Ambient Option. For two circuit models, ACZ-B, the electrical data is divided into two classifications based on the ambient environment where the unit will operate. “Standard Units” operate in ambient temperatures of 105°F or less. Units with the “High Ambient” option will be for ambient temperatures above 105°F. The “Standard Ambient” ACZ-B units have lower electrical requirements where possible. This electrical data will be listed on the unit’s nameplate shipping from the factory. Units with the “High Ambient” option will include not only the addition of a small fan with a filter in the air intake to cool the control , but also a different unit nameplate that lists the larger electrical requirements.

Notes for “Electrical Data Single-and Multi-Point” Power: 1. Unit wire size ampacity (MCA) is equal to 125% of the largest compressor-motor RLA plus 100% of RLA of all other loads in the circuit including the control transformer. 2. The control transformer is furnished and no separate 115V power is required. On ACZ 030B through 155B, for both single- and multi-point power connections, the control transformer is in circuit #1 with control power wired from there to circuit #2. In multipoint power, disconnecting power to circuit #1 will disconnect all control power to the unit. 3. If a separate 115V power supply is used for the control circuit, then the wire sizing amps is 10 amps for all unit sizes. 4. Recommended power lead wire sizes for 3 conductors per conduit are based on 100% conductor ampacity in accordance with NEC. Voltage drop has not been included. Therefore, it is recommended that power leads be kept short. All terminal block connections must be made with copper (type THW) wire. 5. “Recommended Fuse Sizes” are selected at approximately 150% to 175% of the largest compressor RLA, plus 100% of all other loads in the circuit. 6. “Maximum Fuse or HACR breaker size” is selected at approximately 225% of the largest compressor RLA, plus 100% of all other loads in the circuit. 7. The recommended power lead wire sizes are based on an ambient temperature of 86°F (30°C). Ampacity correction factors must be applied for other ambient temperatures. Refer to the National Electrical Code Handbook. 8. Must be electrically grounded according to national and local electrical codes.

Voltage Limitations: Within ± 10 percent of nameplate rating Important: Voltage unbalance not to exceed 2% with a resultant current unbalance of 6 to 10 times the voltage unbalance per NEMA MG-1, 1998 Standard. This is an important restriction that must be adhered to.

Notes for “Compressor and Condenser Fan Amp Draw”: 1. Compressor RLA values are for wiring sizing purposes only but do not reflect normal operating current draw at rated capacity.

Notes for “Field Wiring Data” 1. Requires a single disconnect to supply electrical power to the unit. This power supply must either be fused or use an HACR type circuit breaker. 2. All field wiring to unit power block or optional non-fused disconnect switch must be copper. 3. All field wire size values given in table apply to 75°C rated wire per NEC.

Circuit Breakers (ACZ 030 to 155 only) Factory installed circuit breakers are standard on units with single point power supply only. This option provides unit installed compressor short circuit protection and makes servicing easier.

Application Data Unit Placement ACZ units are for outdoor applications and can be mounted either on a roof or at ground level. For roof mounted applications, install the unit on a steel channel or I-beam frame to the unit above the roof. For ground level applications, install the unit on a substantial base that will not settle. Use a one-piece concrete slab with footings extended below the frost line. Be sure the foundation is level within 1/2" (13mm) over its length and width. The foundation must be strong enough to the weights listed in the Physical Data Tables beginning on page 49.

NOTE: Dimensions in ft (m).

Clearances Do not block the flow of air to and from the condenser coil. Restricting airflow or allowing air recirculation will result in a decrease in unit performance and efficiency because the unit discharge pressure is increased. There must be no obstruction above the unit that would deflect discharge air downward where it could be recirculated back to the inlet of the condenser coil. The condenser fans are propeller type and will not operate with ductwork. Install the unit with enough side clearance for air entrance to the coil and for servicing. Provide sufficient service access to the compressors, electrical control and piping components.

Catalog ACZ-4

Do not allow debris to accumulate near the unit where it could be drawn into the condenser coil. Keep condenser coils and fan discharge free of snow and other obstructions to permit adequate airflow for proper operation.

Restricted Air Flow Hail and Wind Guards

If hail and wind guards are used, care must be taken when considering air flow clearances. The guards add 20 inches to the width of each side of the unit and essentially increase the total unit width by that amount. Wall spacing in the following discussions must be taken from the outside of the guards, i.e. 20 inches from the side of the unit. General

The clearances required for design-life operation of ACZ air-cooled condensers are described in the previous section. Occasionally, these clearances cannot be maintained due to site restrictions such as units being too close together or a fence or wall restricting airflow, or both. Fortunately, the McQuay ACZ condensing units have several features that can mitigate the penalties attributable to restricted airflow. •

The condenser section is “W” shaped, as shown below. This allows inlet air for these coils to come in from either side. A vertical coil and its adjacent angled coil are manifolded together to serve one circuit. Every compressor set has its own independent refrigerant circuit.

•

The MicroTech II™ control is proactive in response to “off-design conditions”. In the case of single or compounded influences restricting airflow to the unit, the microprocessor will act to keep the unit running (possibly at reduced capacity) rather than allowing a complete shut-off on high discharge pressure.

•

The MicroTech II™ control can be programmed to sequence the compressors in the most advantageous way. For example, in the diagram shown below, it might be desirable to program circuit #1 to be the lag circuit (last circuit to reach full load) during periods of high ambient temperatures.

Circuit #2

The following sections discuss the most common situations of condenser air restriction and give capacity and power adjustment factors for each. Note that in unusually severe conditions, the MicroTech II™ controller would adjust the unit operation to remain online until a less severe condition is reached.

Case 1, Building or Wall on One Side of One Unit The existence of a screening wall or the wall of a building in close proximity to an aircooled unit is common in both rooftop and ground level applications. Hot air recirculation on the coils ading the wall will increase compressor discharge pressure, decreasing capacity and increasing power consumption. Only the compressor(s) connected to these coils will be affected. Circuits opposite the wall are unaffected. When close to a wall, it is desirable to place the units on the North or East side of them. It is also desirable to have prevailing winds blowing parallel to the unit’s long axis. The worst case is to have wind blowing hot discharge air into the wall. Figure 21, Unit Adjacent to Wall

Case 2, Two Units Side By Side Two or more units sited side by side are common. If spaced closer than 12 feet (3.7 meters) or 8 feet (2.5meters) depending on size, it is necessary to adjust the performance of each unit; circuits ading each other are affected. NOTE: This case applies only to two units side by side. See Case 3 for three or more parallel units. If one of the two units also has a wall ading it, see Case 1. Add the two adjustment factors together and apply to the unit located between the wall and the other unit. Mounting units end to end will not necessitate adjusting performance. Depending on the actual arrangement, sufficient space must be left between the units for access to the control door opening. See “Clearance” section of this guide for requirements for specific units.

Case 4, Open Screening Walls Decorative screening walls are often used to help conceal a unit either on grade or on a rooftop. These walls should be designed such that the combination of their open area and distance from the unit do not require performance adjustment. It is assumed that the wall height is equal to or less than the unit height when mounted on its base . This is usually satisfactory for concealment. If the wall height is greater than the unit height, see Case 5, Pit Installation. The distance from the ends of the unit to the end walls should be sufficient for service and opening control doors. If each side wall is a different distance from the unit, the distances can be averaged providing either wall is not less than 8 feet (2.4 meters) from the unit. For example, do not average 4 feet and 20 feet to equal 12 feet. Figure 27, Open Screening Walls

Case 5, Pit/Solid Wall Installation Pit installations can cause operating problems and great care should be exercised if they are to be used on an installation. Recirculation and restriction can both occur. A solid wall surrounding a unit is substantially the same as a pit and the data presented here should be used. Steel grating is sometimes used to cover a pit to prevent accidental falls or trips into the pit. The grating material and installation design must be strong enough to prevent such accidents, yet provide abundant open area or serious recirculation problems will occur. Have any pit installation reviewed by McQuay application engineers prior to installation to make sure it has sufficient air-flow characteristics. The installation design engineer must approve the work to avoid an unreasonable risk of accident. Figure 29, Pit Installation

Refrigerant Piping Proper refrigerant piping makes the difference between a reliable or an inefficient problematic system. The primary concerns related to piping are refrigerant pressure drop, a solid liquid feed to the expansion valves, continuous oil return and properly sized refrigerant specialties. The recommended source for refrigerant piping techniques and sizing is the ASHRAE 2002 Refrigeration Handbook, chapter #2. Refrigerant specialties including the expansion valves, solenoid valves, filter drier and sight glasses for use with the remote evaporator applications are supplied and installed by the installing contractor. The remaining components including pipe, insulation, fittings and Schrader valves are also provided and piped by the installer. The optional hot gas by valve with solenoid valve can be provided as a field installed or factory installed option. A holding charge of R22 is provided for the unit. The installer must properly evacuate the piping system and provide the operating charge of R22. Although conflicting piping recommendations can be found in different sources, McQuay offers the following recommendations for these controversial issues. The use of double risers for vertical gas risers is generally not required and should be used only as a last resort to maintain the minimum refrigerant flow to carry oil up the vertical risers. Slightly downsizing the vertical riser is a superior option to providing double risers. Slope the refrigerant lines 1” per 10 feet of horizontal run in the direction of refrigerant flow to assist oil return. Resist using hot gas by for applications when operation in ambient temperature below 40 degrees is expected. This recommendation helps to maintain adequate condensing pressures and liquid refrigerant at the expansion valve when condenser capacities are at their maximum. Pressure drops in the refrigerant lines should be maintained at or below the ASHRAE recommendations and line lengths should be made as short as possible. Exceeding these recommendations will decrease performance and could impact reliability. Small traps should be provided at the base of each major vertical gas riser to assist in the collection of oil. If vertical risers exceed more than 25 feet, install a small trap at the midpoint and not to exceed more than 20 feet intervals. Use caution in sizing the liquid line in applications where the evaporator is above the outdoor section. The weight of the liquid refrigerant in the vertical column will decrease the pressure at the top of the riser (approximately .5 PSI per foot of vertical rise) allowing some of the refrigerant to flash to a gas. Adequate refrigerant subcooling is needed at the outdoor section to prevent large volumes of refrigerant gas at the expansion valve. It is recommended that the piping systems always extend above the highest component in the refrigeration system before dropping down to make the final refrigerant connections to components. This practice will hinder the draining of condensed refrigerant to the lower component when normal shutdown procedures do not occur (such as a power failure). NOTE: Do not run refrigerant piping underground.

Vibration Isolators Vibration isolators are recommended for all roof-mounted installations or wherever vibration transmission is a consideration. The unit should be initially on shims or blocks at the listed free height. When all piping, wiring, flushing, charging, etc. is completed, the springs are adjusted upward to loosen the blocks or shims that are then removed. A rubber anti-skid pad is part of the isolator. Installation of spring isolators requires flexible piping connections and at least three feet of flexible conduit to avoid straining the piping and transmitting vibration and noise.

Isolator Installation The unit should be initially installed on shims or blocks at the listed free height. When all piping, wiring, flushing, charging, etc. is completed, adjust the springs upward to load them and to provide clearance to remove the shims or blocks. Installation of spring isolators requires flexible piping connections and at least three feet of conduit flex tie-ins. Piping and conduit must be ed independently of the unit. Bolting: If the chiller base is to be bolted to the isolators, it is recommended that the short threaded studs usually found on isolators be replaced with eight-inch threaded rod that can extend through the holes on the top of the base and then be bolted. Washers will be required. Models ACZ 010 through 039 cannot be bolted to the isolators.
