PR0-PAC SYSTEM OWNER INSTALLATION MANUAL

4. DETERMINING WATER FLOW

The Pro-Pac is fitted with a water flow switch which inhibits the
operation of the machine when the minimum water flow is inadequate.
Adjust the water flow rate through the heat pump until the green
Water Flow OK lamp on the machine console is illuminated. An
adequate water flow rate has now been achieved.

Ensure isolation valves 'A' and 'B' and bypass valve 'C' are fully open.
Close the bypass valve until the flow light that is positioned on the
heat pump console illuminates and then close it slightly more to allow
for flow loss due to a dirty filter. Remove handle and lock off valve 'C'.
Alternatively a water flow meter can be installed. See data sheets for
flow rates.
