Chapter 8: Product Guide Specifications
OPTIONAL ACCESSORIES
MECHANICAL FLOW SWITCH
A flow switch (shipped loose) must activate a loss of flow alarm if chilled water flow is interrupted.
DIFFERENTIAL TEMPERATURE FLOW (OPTIONAL)
A factory-mounted and wired temperature sensor for inlet and outlet water temperatures must permit a loss of flow alarm if the
temperature difference is within 1° F (adjustable) during chilled water valve operation.
SMOKE DETECTION
A photo-electric smoke detector must be factory installed and wired in the evaporator section of the suction side of the
evaporator blower. The air conditioner will shut down upon sensing smoke in the return air stream.
FIRESTAT
The air conditioner must be provided with a factory-wired and mounted firestat. The firestat will shut down the air conditioner
upon sensing a high return air temperature.
REMOTE WATER DETECTOR: SPOT TYPE
A remote, single-point water and leak detector must be factory supplied and ship separately for field installation. Upon sensing a
water leak, the normally closed water detector control circuit shall open, thereby shutting down the Cold Row CW unit’s
water-producing components.
REMOTE WATER DETECTOR: STRIP TYPE
A 20-ft. long remote strip/cable type water and leak detector must be provided for remote field installation. Upon sensing a
water leak, the normally closed water detector control circuit shall open, thereby shutting down the Cold Row CW unit’s water-
producing components.
CODE CONFORMANCE
The unit must be designed and built to conform to UL
®
STD 1995, certified to CAN/CSA C22.2 No. 236. and listed with ETL.
