locations deny the unit of a continuous source of fresh air which reduces it efficiency and

may prevent adequate heat delivery.

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's condensation.

3.INSTALLATION AND CONNECTION

PVC COUPLER
RECOMMENDED(Provided)

The Spa 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.

3.5 Spa Heat Pu mps Electri ca l 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.

3.INSTALLATION AND CONNECTION

3.6 Initial startup of the Unit

NOTE- In order for the unit to heat the pool or spa, the filter pump must be running to
circulate water through the heat exchanger.

Start up Procedure - After installation is completed, you should follow these steps:

1. Turn on your filter pump. Check for water leaks and verify flow to and from the pool.

2. Turn on the electrical power supply to the unit, then press the key ON/OFF of wire
controller, It should start in several seconds.

3. After running a few minutes make sure the air leaving the top(side) of the unit is
cooler(Between 5-10 )

4. With the unit operating turn the filter pump off. The unit should also turn off automatically,

5. Allow the unit and pool pump to run 24 hours per day until desired pool water temperature
is reached. When the water-in temperature reach setting, The unit just
shuts off. The unit will now automatically restart (as long as your pool pump is running)when
the pool temperature drops more than 2 below set temperature.

Water Flow Switch - the unit is equipped with a flow switch that turns it on when the pool
pump is running and shuts it off when the pump shuts off. This switch is the same type used in
all gas pool heaters and is factory adjusted for normal pool installations. If the pool water
level is more than a few feet above or below the thermostat knob of the unit, your dealer may
need to adjust it at initial startup.

Time Delay- The unit is equipped with a 3 minute built-in solid state restart delay included to
protect control circuit components and to eliminate restart cycling and contactor chatter.
This time delay will automatically restart the unit approximately 3 minutes after each control
circuit interruption. Even a brief power interruption will activate the solid state 3 minute
restart delay and prevent the unit from starting until the 5 minute countdown is completed.

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 within sight of and readily accessible from the uni, 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.
