3.4 Plumbing
The Swimming Pool Heat Pumps exclusive rated flow titanium heat exchanger requires no special plumbing
arrangements except bypass (please set the flow rate according to the nameplate).
The water pressure drop is less than 10kPa at max flow rate. Since there is no residual heat or flame
temperatures, the unit does not need copper heat sink piping. PVC pipe can be run straight into the unit.
Location: Connect the unit in the pool pump discharge (return) line downstream of all filter and pool pumps,
and upstream of any chlorinators, ozonators or chemical pumps.
Standard models have slip glue fittings which accept 40mm NB PVC pipe for connection to the pool or spa
filtration piping. By using a 50 NB to 40NB you can plumb 40NB.
Give serious consideration to adding a quick coupler fitting at the unit inlet and outlet to allow easy draining
of unit for winterizing and to provide easier access should servicing be required.
Since the Heat pump cools down the air about 4 -5
℃
, water may condense on the fins of the horseshoe
shaped evaporator. If the relative humidity is very high, this could be as much as several litres an hour. The
water will run down the fins into the basepan and drain out through the barbed plastic condensation drain
fitting on the side of the basepan. This fitting is designed to accept 20mm clear vinyl tubing which can be
pushed on by hand and run to a suitable drain. It is easy to mistake the condensation for a water leak inside
the unit.
NB: A quick way to verify that the water is condensation is to shut off the unit and keep the pool pump
running. If the water stops running out of the basepan, it is condensation. AN EVEN QUICKER WAY IS TO TEST
THE DRAIN WATER FOR CHLORINE - if the is no chlorine present, then it's condensation.
