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.
