Swimming Pool Heat Pumps Plumbing
INSTALLATION AND CONNECTION
The Swimming Pool Heat Pumps exclusive rated fl ow titanium 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.
Location:
Connect the unit in the pool pump discharge (return) line downstream of all fi lter and pool pumps, and upstream
of any chlorinators, ozonators or chemical pumps.
Standard model have slip glue fi ttings which accept 32mm or 50 mm PVC pipe for connection to the pool or
spa fi ltration piping. By using a 50 NB to 40NB you can plumb 40NB
Give serious consideration to adding a quick coupler fi tting at the unit inlet and outlet to allow easy draining of
unit for winterizing and to provide easier access should servicing be required.
Condensation:
Since the Heat pump cools down the air about 4 -5℃, water may condense on the fi ns 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 fi ns into the basepan and drain out through the barbed plastic condensation drain
fi tting on the side of the basepan. This fi tting 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.
