The fourth part on the circuit is the overload protection on the compressor. It will open if
the unit becomes low on refrigeration or if the improper voltage is used. This part of the
circuit is an automatic reset.

CHILLED WATER CIRCUIT

The chilled water is pumped from the chiller's water tank to the discharge outlet of the
chiller. Then from the discharge outlet, the water travels to the object to be cooled,
through the heat exchanger, and returns through the chillers return line into the water
tank. Be sure to keep all lines full size (1"). If the size of the lines is reduced, then the
flow of water will be restricted, and thus resulting in improper chilling.




























REFRIGERATION SYSTEM

The refrigeration system is a medium temperature system with a range from 35

0

F to

70

0

F. This is the most efficient range. If temperatures below or above this range are

required, they should be discussed with our engineering department. The refrigeration
system also includes a hermetically sealed refrigeration system and all parts, except the
