Installation
Priming the Pump and Connecting the Coolant Loop
DO NOT RUN THE PUMP DRY. If the pump does not establish prime, the pump shaft seal may
overheat and be damaged in less than a minute. Use the following instructions when filling and
assembling the coolant lines to prevent damage to the pump shaft seal.
1. Close the reservoir drain.
2. Fully open the flow control valve (if included).
3. Have extra HFE7500 to add as the pump primes and the coolant loop fills.
4. Fill the reservoir with HFE 7500. Do not fill above the height of the coolant loop connection
fittings or fluid may leak out.
5. Connect the coolant lines from the application to the FPT (female pipe thread) fittings near
the top of the chiller as follows. Do not over tighten the insert and do not use a sealant that
will lock the male threads to the female threads.
a. Connect the coolant line coming back from the application to the RETURN fitting.
b. Connect the coolant line going to the application to the SUPPLY fitting.
RETURN SUPPLY
6. This chiller is equipped with a Phase Reverse Relay. The chiller will not start if the phase
sequence is incorrect. If the chiller fails to start upon installation, have a qualified electrical
technician check the Phase Reverse Relay in the electrical box of the chiller. If the LED is
not brightly lit, the phase sequence is incorrect. The electrical technician should switch any
two of the wires at the incoming power source. Do not change any of the wiring in the
chiller’s electrical box. Check again for proper phase sequence before proceeding with
these instructions.
