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 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 model 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 50NB PVC piping straight
into the unit.
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 base-pan and drain out through the barbed plastic
condensation drain fitting on the side of the base-pan. This fitting is designed to accept 3/4"
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 base-pan, 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.
