REMOTE CONDENSER # M002359AB
FOR OTC and OTM SERIES
ALL Models
CAUTION (REFER TO ACCOMPANYING DOCUMENTS)
CAUTION: RISK OF ELECTRICAL SHOCK. DISCONNECT SWITCH
REQUIRED TO DE-ENERGIZE THE EQUIPMENT BEFORE SERVICING.
THE CHILLER CONTAINS REFRIGERANT.
Be sure that all mechanical piping and wiring conform to federal, state and local codes.
Run the appropriate copper tubing discharge and liquid lines from the chiller (internal to building)
to the condenser (external to building in area where both intake and exhaust are not blocked).
See refrigeration schematic for details. After the tubing has been connected, test the lines for
leaks using nitrogen. Evacuate the lines by connecting a vacuum pump to the interconnecting
tubing. Once it is evacuated, open the Service Valves in the Chiller to “Charge” the lines.
The electrical contactor for the fan(s) is in the condenser cabinet. Connect a power cable
(provided by others) to a fused disconnect (provided by others) located within sight of the
condenser. Run the power cable from the disconnect to the correct terminals in the condenser
box. See electrical schematic for details. All wiring shall be run through appropriate seal-tite.
The unit is pre-charged with R-134a or R-407c refrigerant. The unit was tested with 2 feet of
lines. It may be necessary to add refrigerant for additional line lengths. Please contact the
factory to obtain the proper refrigerant charge.
The chiller system is designed such that the chiller’s compressor and pump run all of the time.
The condenser fan cycles as needed. The hot gas bypass valve and solenoid cycle in order to
provide part load control in the refrigeration system.
