3.INSTALLATION AND CONNECTION
3.4 Swimming Pool Heat Pumps 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 Tempera-
tures, 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 model have slip glue fittings which accept 32mm or 50 mm 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.

CONDENSATION DRAIN
BARB FTG
Condensation: 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.
