3.4 Swimming Pool Heat Pump Plumbing
Location: Connect the unit in the pool pump discharge (return) line downstream of the filter and
circulation pump, but upstream of any chlorinators, ozonators or chemical pumps.
Condensation: Since the heat pump cools down the air by about 4 -5c, condensation will condense
on the fins of the 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 of the heat pump and will drain out
through the drain holes on the bottom of the heat pump.
It is easy to mistake the condensation for a water leak inside the heat pump.
If you turn off the heat pump, but allow the pool water to continue running through it, then after
around 30-mins, the condensation will stop.
A quick way to verify that the water is condensation is to shut off the heat pump but keep the pool
circulation pump running. If the water stops running out of the basepan, after around 30 mins, then
it is condensation. AN EVEN QUICKER WAY IS to TEST THE DRAIN WATER FOR CHLORINE - if
there is no chlorine present, then it is normal condensation.

Flexible hose tail pipe
The Swimming Pool Heat Pump titanium heat exchanger requires no special plumbing
arrangements except a bypass(please set the flow rate according to the faceplate) The water
pressure drop is less than 10kPa at max. flow rate. Flexible hoses or solid PVC pipe can be run
straight into the unit.
3.5 Swimming Pool Heat Pump Electrical Wiring
NOTE: Although the unit heat exchanger is electrically isolated from the rest of the unit, it simply
prevents the flow of electricity to or from the pool water. Earthing the unit is still required to
protect you against short circuits
The heat pump is supplied with an inline RCD and UK plug.
If the unit is connected to an outdoor socket, then the outdoor socket should be protected by an
RCD
Disconnect - A disconnect means (circuit breaker , fused or un-fused switch) should be located
within sight of and readily accessible from the unit, This is common practice on commercial and
residential air conditioners and heat pumps. It prevents remotely-energizing unattended equipment
and permits turning off power at the unit while the unit is being serviced.
