Water supply
Valve
Installation items:
The factory only provides the main unit and the water unit ; the oter items in the illustration
are necessary spare parts for the water system , that provided by users or the installer.
Attention:
Please follow these steps when using for the first time
1.open valve and charge water.
2.make sure that the pump and the water-in pipe have been filled with water.
3.close the valve and start the unit.
3.2 Swimming Pool Heat Pumps Location
The unit will perform well in any outdoor location provided that the following three factors
are present.
1.fresh air - 2.electricity - 3.pool filter piping
The unit may be installed virtually anywhere outdoors.
For indoor pools consult the supplier. Unlike a gas heater,
it has no draft or pilot light problem in a windy area.
Do not place the unit in an enclosed area with a
limited air volume, where the units discharge air
will be re-circulated.
Do not place the unit to shrubs which can block air
inlet. These locations deny the unit of a continuous
source of fresh air which reduces it efficiencyand
may prevent adequate heat delivery.

3.3 How Close To You Pool ?
Normally, the pool heat pump is installed within 7.5 metres of the pool. The longer
the distance from the pool, the greater the heat loss from the piping. For the most part,
the piping is buried. Therefore, the heat loss is minimal for runs of up to 15 metres
(15 metres to and from the pump = 30 metres total), unless the ground is wet or the
water table is high. A very rough estimate of heat loss per 30 metres is 0.6 Kw-hour,
(2000BTU) for every 5 difference in temperature between the pool water and the ground
surrounding the pipe, which translates to about 3% to 5% increase in run time.
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
50NB to 40NB you can plumb 50NB 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
of unit for winterizing and to provide easier access
should servicing be required.

CONDENSATION DRAIN BARB FTG
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 basepan and drain out through
the barbed plastic condensation drain fitting on the side of the basepan. 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 basepan, it is condensation.
AN EVEN QUICKER WAY IS to TEST THE DRAIN WATER FOR CHLORINE - if the is no
chlorine present, then it is condensation.
