3. INSTALLATION AND CONNECTION
3.2 Swimming Pool Heat Pumps Plumbing
The Swimming Pool Heat Pump 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 in less than 10 kPa at max. Flow rate. Since
there is no residual heat or flame Temperature, 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 1.5 inch PVC pipe for connection to
the pool or spa filtration piping. When the water connector is 1 inch to 1.5 inch you can
plumb 1.5 inch PVC piping straight into the unit.
Give serious consideration to adding a quick coupler fitting at the unit inlet and outlet to
allow easy draining od unit for winterizing and to provide easier access should servicing
be required.
Condensation: Since the Heat pump cools down the air about 4-5˚C, 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 liters 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 ½ inch clear vinyl tubing which can be
pushed on by hand and run to suitable drain. It is easy to mistake the condensation for a
water leak inside the heat pump.
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 the basepan. It is condensation.
AN EVEN QUICKER WAY is to TEST THE DRAIN WATER FOR CHLORINE – if there no
chlorine present, then it’s condensation
