NOTE: Do not use automobile antifreeze, or any other fluid

that is not approved for heat exchanger duty. Only use appro-

priately inhibited glycols, concentrated to provide adequate

protection for the temperature considered.

1. Use an electric heater tape for the external piping, if unit

will be exposed to freezing temperatures.

2. Ensure that power is available to the chiller at all times,

even during the off-season, so that the pump, cooler  heat-

ers and heat reclaim have power. Also make sure that the

piping tape heaters have power.

3. On units with pump packages, a heater is supplied with

the hydronic package that will protect this section from

freezing in outdoor-air temperatures down to –20 F

(–29 C), except in the case of a power failure. If the pump

will be subjected to freezing temperatures, steps must be

taken to prevent freeze damage. If the pump will not be

used during this time, it is recommended to drain the

pump and hydronic package and these components are

back-flushed with inhibited glycol. Otherwise, a glycol-

water solution should be considered as the heat transfer

fluid. Drains are located on the pump(s) and suction

guide/strainer for units with hydronic kits. Units without

hydronic kits have a drain mounted on the bottom of the

heat exchanger near the leaving water connection of the

heat exchanger. The Carrier warranty does not cover

damage due to freezing.

4. Cooler heaters that will protect components down to

–20 F (–28.9 C) can be ordered as a factory-installed op-

tion. It should be noted that these heaters will not protect

the cooler from freezing in the event of a power failure.

The Carrier warranty does not cover damage due to

freezing. 

5. Units with the heat reclaim option are supplied with a

heater to protect the reclaim condenser down to 0° F

(–18 C). If the unit controls the heat reclaim circulator

pump and or valves to allow flow through the condenser,

freeze protection to –20 F (–29 C) is provided. Again, it

should be noted that the heaters and pump control will not

protect the reclaim condenser from freezing in the event

of a power failure. The Carrier warranty does not cover

damage due to freezing.

PREPARATION FOR WINTER SHUTDOWN — If the unit

is not operational during the winter months, at the end of cool-

ing season, perform the following: 

CHILLED WATER SYSTEM

1. If the unit has an optional heater on the cooler and the

cooler will not be drained, do not shut off power discon-

nect during off-season shutdown. If the unit has an op-

tional heater on the cooler and the cooler will be drained,

open the circuit breaker for the heater, CB-HT or shut off

power during off-season shutdown.

2. Draining the fluid from the system is highly recommend-

ed. If the unit is equipped with a hydronic package, there

are additional drains in the pump housing and strainer

that must be opened to allow for all of the water to drain.

Cross break these faces.

Hem these 3 edges both top

and bottom.
