The Swimming Pool Heat Pumps exclusive rated
fl
ow
ti
tanium heat exchanger requires no special plumbing
arrangements except bypass (please set the
fl
ow rate according to the nameplate). The water pressure drop is less
than 10kPa at max.
Flow rate: Since there is no residual heat or
fl
ame Temperatures, the unit does not need copper heat sink piping.
PVC pipe can be run straight into the unit.
Loca
ti
on: Connect the unit in the pool pump discharge (return) line downstream of all
fil
ter and pool pumps, and
upstream of any chlorinators, ozonators or chemical pumps.

Voltage range should be 220-230 volts for single phase, and 380-400 volts for 3 phase units. Voltage ranges outside
these parameters will cause heater damage and void your warranty.
