2-4 Safety Devices and Interlocks

Caution! Protect the system from freezing with inhibited industrial grade glycol 20ºF below the leaving water temperature set point. Condensation may form inside the pump tank and dilute the mixture, therefore the freezing point should be verified periodically. See Figure 6 on page 18 for the correct mixture.

Crankcase Heater

All of the chillers are equipped with a compressor crankcase heater. It is wired through the control transformer that operates continuously whenever power is applied to the chiller, and the compressors are off.

Caution! Energize the crankcase heater for at least 24 hours before initial startup to drive dissolved refrigerant from the compressor oil. Failure to do so will damage the compressor. If unit is mounted outdoors, power to the unit (and the main power switch) must remain on 24 hours per day, 7 days per week to prevent liquid migration to the compressor.
