FLOW METER METHOD (SEE FIG 3.)
Ensure isolation valves ‘A’ and ‘B’ and bypass valve ‘C’ are fully open.
Close e bypass valve until e flow light at is positioned on e
heat pump console illuminates and en 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.
The Pro-Pac is fitted wi a water flow switch which inhibits e
operation of e machine when e minimum water flow is inadequate.
Adjust e water flow rate rough e heat pump until e green
Water Flow OK lamp on e machine console is illuminated. An
adequate water flow rate has now been achieved.
