Introduction General Description McQuay SeasonPak air-cooled water chillers are complete, self-contained automatic refrigerating units. Every unit is completely assembled, factory wired, charged, and tested. Each unit consists of twin air-cooled condensers with integral subcooler sections, multiple accessible hermetic compressors, replaceable tube dual circuit shell-and-tube evaporator, and complete refrigerant piping. Liquid line components include manual liquid line shutoff valves, sight-glass/moisture indicators, solenoid valves, and double diaphragm hydraulic element thermal expansion valves. Other features include compressor crankcase heaters, an evaporator heater for chilled water freeze protection, limited pumpdown during on or off periods, compressor lead-lag switch to alternate the compressor starting sequence, and sequenced starting of compressors. The electrical control center includes all safety and operating controls necessary for dependable automatic operation. Condenser fan motors are fused in all three phases and started by their own three-pole contactors. Compressors are not fused but may be protected by optional circuit breakers, or by a field installed fused disconnect. Inspection Check all items carefully against the bill of lading. Inspect all units for damage upon arrival. Report shipping damage and file a claim with the carrier. Check the unit name plate before unloading, making certain it agrees with the power supply available. McQuay is not responsible for physical damage after unit leaves the factory. Note: Unit shipping and operating weights are available in the Physical Data tables beginning on page 12. Installation Note: Installation is to be performed by qualified personnel who are familiar with local codes and regulations. WARNING Sharp edges and coil surfaces are a potential hazard. Avoid contact with them. Handling Be careful to avoid rough handling of the unit. Do not push or pull the unit from anything other than the base. Block the pushing vehicle away from the unit to prevent damage to the sheet metal cabinet and end frame (see Figure 1). To lift the unit, 2 1/2" (64mm) diameter lifting holes are provided in the base of the unit. Arrange spreader bars and cables to prevent damage to the condenser coils or cabinet (see Figure 2).

Figure 1, Suggested pushing arrangement Blocking required across full width Figure 2, Suggested lifting arrangement Spreader bars recommended (Use Caution) NOTE: Number of fans can vary from this diagram. Lifting method remains the same. Location Must use these rigging holes. (Be aware of control box location) Unit Placement ALR units are for outdoor applications and can be mounted on a roof or ground level. Set units on a solid and level foundation. For roof mounted applications, install the unit on a steel channel or I- beam frame to support the unit above the roof. For ground level applications, install the unit on a substantial base that will not settle. A one piece concrete slab with footings extended below the frost line is recommended. Be sure the foundation is level (within 1/2 [13 mm] over its length and width). The foundation must support the operating weights listed in the Physical Data tables beginning on page 12. On ground level applications protect fins against vandalism using the optional coil guards or by erecting a screen fence. The fence must allow free flow of air to the condenser coil for proper unit operation. 4 IM 676

Clearances The flow of air to and from the condenser coil must not be limited. Restricting air flow or allowing air recirculation will result in a decrease in unit performance and efficiency. 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 on the fan outlet. Install the unit with enough side clearance for air entrance to the coil and for servicing. Provide service access to the evaporator, compressors, electrical control panel and piping components as shown in Figure 3. Do not allow debris to accumulate near the unit. Air movement may draw debris into the condenser coil causing air starvation. Give special consideration to low ambient operation where snow can accumulate. Keep condenser coils and fan discharge free of snow or other obstructions to permit adequate airflow. Figure 3, Clearance requirements 5 ft. (1524mm) Clearance for air inlet 4 Ft.

(1524mm) clearance for air inlet ALR Unit Size 032E -075E 080E - 185E Minimum "X" Dimension 8 ft (2438 mm) 10 ft (3048 mm) Sound Isolation The ultra-low sound levels of the ALR reciprocating chiller is suitable for most applications. When additional sound reduction is necessary, locate the unit away from sound sensitive areas. Avoid locations beneath windows or between structures where normal operating sounds may be objectionable. Reduce structurally transmitted sound by isolating water lines, electrical conduit and the unit itself. Use wall sleeves and rubber isolated piping hangers to reduce transmission of water or pump noise into occupied spaces. Use flexible electrical conduit to isolate sound through electrical conduit. Spring isolators are effective in reducing the low amplitude sound generated by reciprocating compressors and for unit isolation in sound sensitive areas. Service Access Each end of the unit must be accessible after installation for periodic service. Compressors, filterdriers, and manual liquid line shutoff valves are accessible on each side of the unit adjacent to the control box. High pressure, low pressure, and motor protector controls are on the compressor. Freezestats and cooler barrel thermostats are near the cooler. Most other operational, safety and starting controls are located in the unit control box. The condenser fan and motors can be removed from the top of the unit. IM 676 5

Vibration Isolators Vibration isolators are recommended for all roof mounted installations or wherever vibration transmission is a consideration. Table 1 lists isolator loads and type. Table 2 lists spring isolator part numbers for all unit sizes. See Dimensional Data beginning on page 36 for dimensions required to secure each isolator to the mounting surface.

Water Piping Local authorities can supply the installer with the proper building and safety codes required for safe and proper installation. Install piping with minimum bends and changes in elevation to minimize pressure drop. Consider the following when installing water piping: 1. Vibration eliminators to reduce vibration and noise transmission to the building. 2. Shutoff valves to isolate the unit from the piping system during unit servicing. 3. Manual or automatic air vent valves at the high points of the system. Install drains at the lowest points in the system. 4. A means of maintaining adequate system water pressure (expansion tank or regulating valve). 5. Temperature and pressure indicators located at the unit to aid in unit servicing. 6. A strainer or other means of removing foreign matter from the water before it enters the pump. Place the strainer far enough upstream to prevent cavitation at the pump inlet (consult pump manufacturer for recommendations). The use of a strainer will prolong pump life and keep system performance up. 7. Place a strainer in the water line just before the inlet of the evaporator. This will help prevent foreign material from entering and decreasing the performance of the evaporator. CAUTION If separate disconnect is used for the 110V supply to the evaporator heating cable, mark the disconnect clearly to ensure disconnect is not accidentally shut off during cold seasons. 8. The shell-and-tube evaporator has a thermostat and heating cable to prevent freeze-up down to - 20 F (-29 C). It is suggested that the heating cable be wired to a separate 110V supply circuit. As shipped from the factory, the heating cable is wired to the control circuit. All water piping to the unit must also be protected to prevent freezing. 9. If the unit is used as a replacement chiller on a previously existing piping system, flush the system thoroughly before unit installation. Regular water analysis and chemical water treatment on the evaporator is recommended immediately at equipment start-up. 10. The total water volume in the system should be sufficient to prevent frequent on-off cycling. Turnover rate should not be less than 15 minutes for normal variable cooling loads. Turnover rate for process cooling or a constant load,should not be less than 6 minutes. 11. When glycol is added to the water system for freeze protection, the refrigerant suction pressure will be lower, cooling performance less, and water side pressure drop greater. If the percentage of glycol is high, or if propylene is used instead of ethylene glycol, the added pressure drop and loss of performance could be substantial. Reset the freezestat and low leaving water alarm temperatures. The freezestat is factory set to default at 36 F (2.2 C). Reset the freezestat setting to approximately 4 to 5 degress F (2.3 to 2.8 degress C) below the leaving chilled water setpoint temperature. See the section titled Glycol Solutions for additional information concerning glycol. 12. Perform a preliminary leak check before insulating the piping and filling the system. 13. Piping insulation should include a vapor barrier to prevent condensation and possible damage to the building structure. IM 676 7

Figure 4, Typical field evaporator water piping Vent Outlet Drain Vibration Eliminator Valved pressure gauge Water strainer Vibration Eliminator Gate valve Flow Balancing Switch valve Protect all field piping against freezing Gate valve Flow Switch Mount a water flow switch in either the entering or leaving water line to shut down the unit when water flow is interrupted. A flow switch is available from McQuay (part number 00175033-00). It is a paddle type switch and adaptable to any pipe size from 3 (76mm) to 8 (203mm) nominal. Certain minimum flow rates are required to close the switch and are listed in Table 3. Installation should be as shown in Figure 5. Connect the normally open contacts of the flow switch in the unit control center at terminals 5 and 6. There is also a set of normally closed contacts on the switch that can be used for an indicator light or an alarm to indicate when a no flow condition exists. Freeze protect any flow switch that is installed outdoors. NOTE: Differential pressure switches are not recommended for outdoor installation.

Note: On units sizes 160E through 185E there is a diagonal bracket off of a vertical support which will interfere with the water connection if brought in from the side. This brace can be removed, but only after the unit is in place. Refrigerant Charge All units are designed for use with HCFC-22 and other refrigerants. See nameplate for specific refrigerant used. Units are shipped with an operating charge. The operating charge (using HCFC-22) for each unit is shown in the Physical Data tables beginning on page 12. Note: The procedure does not specify the type of glycol. Use the derate factors found in Table 4 for corrections when using ethylene glycol and those in Table 5 for propylene glycol. Glycol Solutions The system glycol capacity, glycol solution flow rate in GPM, and pressure drop through the cooler may be calculated using the following formulas and table. 1. Capacity -- Find the reduced capacity by multiplying the chiller s capacity with water by the capacity correction factor C. 2. Flow -- To determine evaporator gpm (or Delta-T) knowing Delta-T (or gpm) and capacity: 24 capacity( glycol) Glycol GPM = G (from table) Delta T For Metric Applications -- To determine evaporator L/s (or Delta-T) knowing Delta-T (or L/s) and kw: kw Glycol L / s = Flow(from table) 4.18 Delta T 3. Pressure drop -- To determine pressure drop through the evaporator, when using glycol, enter the water pressure drop curve on page 11 at the actual glycol GPM. Multiply the water pressure drop by PD correction factor from Table 4 or Table 5 to obtain corrected glycol pressure drop. 4. To determine the unit's power consumption when using glycol, multiply the water system kw by factor kw. Test coolant with a clean, accurate glycol solution hydrometer (similar to that found in service stations) to determine the freezing point. Obtain percent glycol from the freezing point table below. On glycol applications it is normally recommended by the supplier that a minimum of 25% solution by weight be used for protection against corrosion. IM 676 9

CAUTION Do not use an automotive grade antifreeze. Industrial grade glycols must be used. Automotive antifreeze contains inhibitors which will cause plating on the copper tubes within the chiller evaporator. The type and handling of glycol used must be consistent with local codes.

Evaporator Water Flow and Pressure Drop Evaporator flow rate must fall between the minimum and maximum values shown in the evaporator pressure drop curve. Flow rates below the minimum values will result in laminar flow which will reduce efficiency, cause erratic operation of the expansion valve and could cause low temperature cutouts. Flow rates exceeding the maximum values can cause erosion on the evaporator water connections and tubes. Measure the chilled water pressure drop through the evaporator at field installed pressure taps. It is important not to include the effect of valves or strainers in these readings. Varying chilled water flow through the evaporator while the compressor(s) are operating is not recommended. Figure 6, Evaporator water pressure drop curve IM 676 11

Electrical Data Field Wiring CAUTION Internal power wiring to the compressors for single and multiple point option are different. Field wiring must be installed according to unit wiring diagram. Wiring must comply with all applicable codes and ordinances. Warranty is void if wiring is not in accordance with specifications. Copper wire is required for all power lead terminations at the unit. Aluminum or copper can be used for all other wiring. ALR units may be ordered with internal power wiring for either single or multiple point power connection. If single point power connection is ordered, a single large power terminal block is provided and wiring within the unit is sized in accordance with the National Electrical Code. A single field supplied fused disconnect is required. An optional factory mounted transformer may be installed. If multiple point power wiring is ordered, three power connections, one per compressor circuit, one for condenser fans, and control circuit, are required. Separate field supplied fused disconnects are required for each of the three circuits. A single power block is provided for all of the condenser fans and the optional 115V control transformer. If the evaporator heater is on a separate disconnect switch from the main unit power supply, the unit may be shut down without defeating the freeze protection provided by the cooler heater. 18 IM 676

Notes for Electrical Data Single Point and Electrical Data Multiple 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. If the control transformer option is furnished, no separate 115v power is required. 3. If a separate 115V power supply is used for the control circuit, then the wire sizing amps is: 10 amps for unit sizes ALR032E through ALR075E 12 amps for unit sizes ALR080E through ALR185E 4. Recommended power lead wire sizes for 3 conductors per conduit are based on 100% conductor ampacity in accordance with NEC. Wire sizes for 6 conductors per conduit are based on 80% 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. The unit power terminal block may have 2 lugs per phase. Single or parallel conductors should be used for power connections as listed under Recommended Power Lead Wire Size. 6. Recommended Fuse Sizes are selected at approximately 150% of the largest compressor RLA, plus 100% of all other loads in the circuit. 7. Maximum Fuse Sizes are selected at approximately 225% of the largest compressor RLA, plus 100% of all other loads in the circuit. 8. The recommended power lead wire sizes are based on an ambient temperature of 86 F. Ampacity correction factors must be applied for other ambient temperatures. Refer to the National Electrical Code Handbook. Voltage Limitations: Unit Nameplate - 208V/60Hz/3Ph: 187V to 253V (except ALR060E through ALR155E: 187V to 220V) Unit Nameplate - 230V/60Hz/3Ph: 187V to 253V (except ALR060E through ALR155E: 207V to 253V) Unit Nameplate - 460V/60Hz/3Ph: 414V to 506V Unit Nameplate - 575V/60Hz/3Ph: 517V to 633V 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. If unit is equipped with SpeedTrol condenser fan motors, the first motor on each refrigerant circuit is a single phase, 1hp motor, with a FLA of 2.8 amps at 460 volts, 5.6 amps at 208, 230, and 575 volts. 2. Compressor LRA for reduced inrush start are for the first winding only. If the unit is equipped with SpeedTrol motors, the first motor is a single phase, 1 hp motor, with a LRA of 7.3 amps at 460 volts, 14.5 amps at 208, 230 and 575 volts. Notes for Field Wiring Data - Both Single and Multiple Point Power: 1. Single point power supply requires a single disconnect to supply electrical power to the unit. This power must be fused. 2. Multiple point power supply requires two independent power circuits each with separate disconnects and a separate control circuit. 3. All field wiring to unit power block or optional non-fused disconnect switch must be copper. 4. All field wire size values given in table apply to 75 C rated wire per NEC. 34 IM 676

Unit Layout and Principles of Operation Figure 10, Major component locations The figure below illustrates component locations for each unit size. Control Center All electrical controls are enclosed in a weatherproof control center with keylocked, hinged access doors. The control center has two separate compartments, high voltage and low voltage. All high voltage components are located in the compartment on the right side of the unit. The low voltage components are located on the left side with the live terminals behind the deadfront panel. This protects service personnel from live terminals when accessing the adjustable and resettable controls.

Start-up and Shutdown Pre Start-up 1. Open all electric disconnects and check all electric connections for tightness. Check all compressor valve connections for tightness. 2. Inspect all water piping for flow direction and correct connections at the evaporator. 3. Verify thermostat water temperature sensor is installed in the leaving water line (supply to building). On all ALR units the sensor well and sensor are factory mounted. 4. Check compressor oil level. The oil level should be visible in the oil sightglass. 5. Check voltage of the unit power supply and make certain voltage is within ±10% of nameplate rating. 6. Check unit power supply wiring for proper ampacity and a minimum insulation temperature of 75 C. 7. Verify all mechanical and electrical inspections have been completed according to local codes. 8. Verify all auxiliary control equipment is operative and an adequate cooling load is available. 9. Open compressor suction and discharge shutoff valves until backseated. Always replace valve seal caps. 10. Open control stop switch S1(off) and place pumpdown switches PS1 and PS2 on manual pumpdown,. Turn on the main power and control disconnect switches. This will energize crankcase heaters. Wait at least 12 hours before starting up unit. 11. Open all water flow valves and start the chilled water pump. Check all piping for leaks and vent the air from the evaporator as well as from the system piping. Flush the evaporator and system piping to obtain clean, noncorrosive water in the evaporator. NOTE: If LWC1 is a Unit 33 Metasys control, the control must be energized before the chilled water flow switch is closed. CAUTION Most relays and terminals in the unit control center are energized with S1 and the control circuit disconnect on. Do not close S1 until start-up. Start-up 1. Verify compressor suction and discharge shutoff valves are backseated. Always replace valve seal caps. 2. Open oil equalization line valve (ALR 080E through 185E only). 3. Open manual liquid line shutoff valve at the outlet of the condenser subcooler. 4. Set temperature controller LWC1 to the desired chilled water temperature. Set the control band. 5. Start auxillary equipment by turning on the following: Time clock Ambient thermostat and/or remote on/off switch Chilled water pump. 6. Verify pumpdown switches PS1 and PS2 are in manual pumpdown (open) position. If pressures on the low side of the system are above 60 psig (414 kpa), the unit will start and pump down. 40 IM 676

7. After compressor lockout timer TD1 has timed out, start the system by moving pumpdown switches PS1 and PS2 to auto pumpdown position. 8. After running the unit for a short time, check the following: Oil level in each compressor crankcase Rotation of fans Flashing in refrigerant sightglass. 9. Verify superheat temperature is at the factory setting of 8 to 12 degrees F (4.4 to 6.7 degrees C). 10. After system performance has stabilized, complete the Compressorized Equipment Warranty Form (Form No. 415415Y) to obtain full warranty benefits. Return the form to McQuay International through your sales representative. Sequence of Operation The following sequence of operation is typical for ALR SeasonPak air-cooled water chiller, Models ALR 032E through ALR 185E (items in italics apply only to Models ALR 080E through 185E). The sequence varies depending upon options. Start - up With the control circuit power on and the control stop switch S1 closed, 115V power is applied through the control circuit fuse F1 to the compressor crankcase heaters HTR1 and HTR2 (HTR3 and HTR4), the compressor motor protections MP1 and MP2 (MP3 and MP4), and the primary of the 24V control circuit transformer. The 24V transformer provides power to the contacts of the low pressure controls LP1 and LP2 and the compressor lockout timer TD1 and TD2. When the remote time clock or manual shutdown switch turns on the chilled water pump, the flow switch closes and 115V power is applied to the relay contacts on the leaving water control LWC1. The unit will automatically operate in response to the LWC1 if the manual pumpdown switches PS1 and PS2 are closed ( in the auto position); the compressor lockout time relays R5 and R6 (R7 and R8); and the freezestats FS1 and FS2, high pressure controls HP1 and HP2, and the compressor motor protectors MP1 and MP2 (MP3 and MP4) do not sense failure conditions. On a call for cooling, the leaving water control LWC1 completes the circuit to the liquid line solenoid valve SV1 for refrigerant circuit #1, opening the valve and allowing refrigerant to flow through the expansion valve and into the evaporator. As the evaporator refrigerant pressure increases, the low pressure control LP1 closes. This energizes the compressor starting relay R9, starting the compressor via the compressor contactors M1 and M5. Closing the R9 contacts also energizes the condenser fan motor contacts M11 and M12 starting the fan motors. As additional stages of cooling capacity are required, the leaving water control LWC1 energizes the liquid line solenoid valve SV2 of the refrigerant circuit #2. After the compressor sequencing time delay TD11 has closed, the same starting sequence is initiated in refrigerant circuit #2. If still more cooling is required, the leaving water control will start the remaining compressors and then de-energize unloader solenoids until the capacity requirement is met. IM 676 41

Pumpdown As the leaving water control is satisfied, it will unload the compressor(s) and then de-energize the liquid line solenoid valve(s) SV1 and SV2, causing the valve(s) to close. When the compressor has pumped most of the refrigerant out of the evaporator and into the condenser, the low pressure control(s) LP1 and LP2 will open. If the refrigerant leaks into the low side causing the pressure to close the low pressure controls LP1 and LP2, the compressor will start after a two-hour time delay. For normal temperature controlled operation, the timer is bypassed and the compressor will start on a refrigerant pressure rise. Note: Do not shut the unit down without going through the pumpdown cycle. Flow switch, time clock, and ambient lockout thermostat must be wired to allow pumpdown when unit is turned off.. 42 IM 676
