Installation items:
The factory only provides the main unit and the water unit; the other items in the illustration
are necessary spare parts for the water system ,that provided by users or the installer.
Attention:
Please follow thesesteps when using for the first time
1.Open valve andcharge water.
2.Make sure thatthe pump and the water-in pipe have been filled with water.
3.Close the valve and start the unit.
ATTN: It is necessary that the water-inpipe is higher than the pool surface.

Sand filter
(or other type filter)

3.INSTALLATION AND CONNECTION
The unit willperform well in any outdoor locationprovided that the following three factorsare
presented:
1. Fresh Air - 2. Electricity - 3. Pool filter piping
The unit maybe installed virtually anywhere outdoors. For indoor pools please consult the
supplier. Unlike a gas heater, it hasno draft orpilot light problemin 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 theunit of a
continuous source of fresh air which reduces it efficiency and may prevent adequate heat
delivery.
3.2 Swimming Pool Heat Pumps Location
Normally, the pool heat pump is installed within 7.5 metres of the pool. The longer the
distance from thepool, the greater the heat loss from the piping. For the most part ,the piping
is buried. Therefore, the heat loss is minimalfor runs ofup to15 meters(15 meters to and from
the pump =30 meters total), unless the ground is wet or the water table is high. A very rough
estimate of heatloss per 30meters is 0.6kW-hour,(2000BTU) for every 5 difference in
temperature between the pool water and the ground surrounding the pipe, which translates to
about 3% to5% increase in run time.

3.INSTALLATION AND CONNECTION
3.4 Swimming Pool Heat Pumps Plumbing
Location: Connect the unit in the pool pump discharge (return) line downstream of all filter
and pool pumps,and upstream ofany chlorinators, ozonators or chemical pumps.
Standard model haveslip glue fittingswhich accept 32mmor 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 fittingat 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 ofthe horseshoe shaped evaporator. If the relative humidity is very high, this could
be as muchas several litresan hour. The water will run down the fins into the basepan and
drain out throughthe barbed plasticcondensation drain fittingon the sideof the basepan.
This fitting isdesigned to accept 20mm clear vinyl tubing which can be pushed on by hand
and run toa suitable drain. It is easy to mistake the condensation for a water leak inside the
unit.
NB: Aquick way to verify that the water is condensationis 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 WAYIS to TEST THE DRAIN WATER FOR CHLORINE- if theis no chlorine
present, then it'scondensation.

The Swimming Pool Heat Pumps exclusive rated flow titanium heat exchanger requires no
special plumbing arrangementsexcept bypass(please set the flow rate according to the
nameplate). The water pressure drop is less than 10kPa at max. Flow rate. Sincethere is no
residual heat or flame Temperatures, The unit does notneed copper heatsink piping. PVC
pipe can berun straight into the unit.

3.5 Swimming Pool Heat Pumps Electrical Wiring
NOTE: Althoughthe unit heatexchanger is electricallyisolated from therest of theunit, it
simply prevents theflow of electricityto or fromthe pool water. Grounding the unit is still
required to protectyou against shortcircuits inside theunit. Bonding isalso required.
3.INSTALLATION AND CONNECTION
3.6 Initial start-up of the Unit
NOTE- In orderfor the unitto heat the pool or spa, the filter pump must be running to
circulate water throughthe heat exchanger.
Start up Procedure- Afterinstallation is completed, you should follow these steps:
1. Turnon your filterpump. Check for water leaks and verify flow to and from the pool.
2. Turnon the electrical power supply to the unit, then press the key ON/OFF of wire
controller, Itshould start in several seconds.
3. Afterrunning a fewminutes make sure the air leaving the top(side) of the unit is
cooler(Between 5-10 )
4. With theunit operating turn the filter pump off. The unit should alsoturn off automatically,
5. Allowthe unit andpool pump to run 24 hours per day until desired pool water temperature
is reached. Whenthe water-in temperature reaches this setting, the unit will slow down for a
period of time,if the temperature is maintained for 45 minutes the unit will turn off. The unit
will now automaticallyrestart (as long as your pool pump is running)when the pool
temperature drops morethan 0.2 below set temperature.
Time Delay- The unit is equipped with a 3 minute built-in solid staterestart delay included to
protect control circuitcomponents and to eliminate restart cycling and contactor chatter.
This time delaywill automatically restart the unit approximately 3 minutes after each control
circuit interruption. Evena brief power interruption will activate the solid state 3 minute
restart delay andprevent the unit from starting until the 5 minute countdown is completed.
The unit hasa 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 conduitnipple and wire-nut the electric supply wires to the three connections
already in thejunction box (four connections if three phase). To complete electrical hookup,
connect Heat Pumpby electrical conduit, UF cable or other suitable means as specified (as
permitted by localelectrical authorities) to a dedicated AC power supply branch circuit
equipped with theproper circuit breaker, disconnect or time delay fuseprotection.
Disconnect -A disconnect means (circuit breaker , fused or un-fused switch) should be
located within sightof and readily accessible from the unit, This is common practice on
commercial and residentialair conditioners and heat pumps. It prevents remotely-energizing
unattended equipment andpermits turning off power at the unit while the unit is being
serviced.
