3. INSTALLATION AND CONNECTION
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 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: 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 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 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.
3.5 Swimming Pool Heat Pumps 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. Grounding the unit is still required to
protect you against short circuits inside the unit. Bonding is also required.
The unit has a separate molded-in junction box with a standard electrical conduit nipple already in
place. Just remove the screws and the front panel, feed your supply lines in through the conduit
nipple and wire-nut the electric supply wires to the three connections already in the junction box
(four connections if three phase). To complete electrical hookup, connect Heat Pump by electrical
conduit, UF cable or other suitable means as specified (as permitted by local electrical authorities)
to a dedicated AC power supply branch circuit equipped with the proper circuit breaker,
disconnect or time delay fuse protection.
Disconnect - A disconnect means (circuit breaker, fused or un-fused switch) should be located
