DESCRIPTION
Packaged air-cooled liquid chiller factory wired, piped, and charged with HFC-134a. Upward
discharge airflow minimizes directional sound and dissipates heat away from surrounding areas.
FEATURES
Cooler is mechanically cleanable ‘‘flooded’’ shell-and-tube type
with removable heads. It is tested and stamped in accordance
with ASME Code for a refrigerant working side pressure of
220 psig (1517 kPa) and a maximum fluid side pressure of
300 psig (2068 kPa) (250 psig [1724 kPa] in Canada) and is
insulated with
Cooler can be equipped with electric heater to help protect against
cooler freeze-up (use of inhibited glycol anti-freeze recommended
for freeze protection).
Compressor is semi-hermetic twin screw design with refrigerant
gas cooled motor and integral oil filter and discharge gas muffler.
Complete thermal and electrical protection is provided.
Air-cooled condenser is constructed of fins mechanically bonded
to seamless copper tubes. Coils are leak and pressure tested at
450 psig (3103 kPa).
Condenser fans are direct driven 11-blade, shrouded axial type,
statically and dynamically balanced, discharging air vertically
upward, protected by coated steel wire safety guards.
3
⁄4-in. (19 mm) closed-cell polyvinyl chloride foam.
Condenser fan motors are totally enclosed 3-phase with permanently lubricated bearings and Class F insulation (except speed
control motors).
Each refrigerant circuit includes oil separator, high side pressure
relief device, liquid and discharge line shutoff valve, filter drier,
moisture indicating sight glass, expansion/level control device.
Microprocessor control includes keypad with diagnostic display
displaying set points, time, system status (including temperatures,
pressures and % loading) and the alarm conditions.
Automatic compressor lead/lag.
Capacity control based on leaving chilled water temperature with
return water temperature sensing.
7-Day time scheduling of pump(s) and chiller.
60-Hz Models: 080, 090, 106, 115, 125, 136, 151, 161, 176, 206,
226, 251, and 265.
50-Hz Models: 080, 090, 105, 106, 115, 125, 136, 150, 160, 161,
175, 205, 225, 226, 250, and 265.

FIELD WIRING DIAGRAM
NOTES:
1. Factory wiring is in accordance with National Electrical Code (NEC). Field modifications or additions must be in compliance with all applicable codes.
2. Wiring for main field power supply must be rated 75° C minimum. Use copper for all
units. Maximum incoming wire size for each terminal block is 500 kcmil.
3. Power for control circuit should be supplied from a separate source through a field
supplied fused disconnect with 30 amp maximum protection for 115voltcontrolcircuits
and 15 amp maximum protection for 230 volt control circuit. Connect control circuit
power to terminals 1 and 2 of TB4. Connect neutral side of supply to terminal 2 of TB4.
Control circuit conductors for all units must be coppr only. 380/415 control power wired
at factory. Requires field supplied neutral connection.
4. Terminals 13 and 14 of TB2 are for field external connection for remote ON-OFF. The
contacts must be rated for dry circuit application capable of handling a 24 vac to 50 mA
load.
5. Terminals 11 and 12 of TB2 are for chilled water flow switch (CWFS) and chilled water
pump interlock (CWPI) functions. The contacts must be rated for dry circuit application
capable of handling a 24 vac to 50 mA load.
6. Terminals T3 and T4 on relay board are for chilled water pump. The maximum load
allowed for the chilled water pump relay is 125 va sealed, 1250 va inrush at 115 or
230 volt.
