3. Installation and Connection
3.1 Remarks
The factory supplies the heat pump on its own. Other components,
including a by-pass where necessary, must be supplied by the user or
installation technician.
N.B.:
Please follow the steps below when installing the heat pump:
1. Any addition of chemicals must take place in the pipes located
behind the heat pump.
2. Install a by-pass if the water flow of the swimming pool pump is
more than 20% above the permitted flow through the heat
exchanger of the heat pump.
3. Install the heat pump above the surface level of the swimming
pool.
4. Always install the heat pump on a firm base and use the damping
rubbers supplied to avoid vibration and noise.
5. Always keep the heat pump straight up. If the appliance was held in
a diagonal position, wait for at least 24 hours before starting the
heat pump.

3.2 Siting of the Heat Pump
The appliance will operate properly in any location, provided that three
points are observed:
1. Fresh Air - 2. Electricity - 3. Swimming pool filters
The appliance may be installed practically anywhere outside, as long as
minimum distances to other objects are observed
.
3.3 Distance from the Swimming Pool
Install the heat pump as close as possible to the swimming pool in order to
limit heat loss through the pipes.
Ensure a firm base and place the heat pump on the rubber blocks to avoid
vibration. All exposed pipework is to
be insulated to avoid heat loss.
3.4 Installing the Check-Valve
N.B.– When using automatic chlorine and pH dosing systems, it is
extremely important to protect the heat pump from excessive
concentrations that could damage the heat exchanger. For this
CAUTION:
Do not place the appliance in
an enclosed space with
restricted volume of air where
the air expelled would be
re-used, or near to shrubbery
that might block the air inlet.
These locations hinder the
continuous flow of fresh air,
resulting in a reduction in
efficiency and possibly
obstructing adequate supply
of heat.
See diagram for the
minimum distances.

- 7 -
reason, facilities of this kind must always be installed in the piping
located BEHIND the heat pump, and it is recommended to install a
check-valve to prevent reverse flow in the absence of water circulation.
Damage to the heat pump caused by failing to observe these precautions is
not subject to the warranty.
3.5 Typical Setup
Remark – This setup is only an example for demonstration

- 8 -
3.6 Setting the By-pass
How to get the optimum water flow:
Please turn on the heat pump under heating function, firstly close the
by-pass then open it slowly to start the heat pump (the machine can't start
running when the water flow is insufficient).
Continue to adjust the by-pass, at the meantime to check the Inlet water
temp. & Outlet water temp., it will be optimum when the difference is
around 2 degree.
Please take below steps to
adjust the by-pass:
1. Valve 1 wide open. Valve 2
& valve 3 closed.
2. Slowly open valve 2 &
valve 3 by half, then close the
valve 1 slowly to increase the
water flow to valve 2 & valve
3.
3. If it shows ‘ON’ or ‘EE3’ on
display, it means the water
flow into heat pump is not
enough, then you need adjust
the valves to increase the
water flow through the heat
pump.

- 9 -
3.7 Electrical Connection
Important - Although the heat pump is electrically insulated from the rest
of the swimming pool system, this merely prevents flow of current from
and to the swimming pool water. An earth is still necessary to protect you
against short circuits within the appliance. Ensure that there is a good
earth.
Check beforehand whether the supply voltage corresponds to the
operating voltage of the heat pump.
It is advisable to make use of a separate fuse (delay type – D curve) along
with adequate cabling (see table below).
The heat pump must be used exclusively with the filter pump. For this
reason, connect to the same fuse as the filter pump. If no water flows
through the heat pump while in operation, it may be damaged and then
the warranty is invalidated.
Connect the cable carrying the current to the clamp connector block behind
the panel located next to the fan.

These should be seen as guidelines only. Check the local regulations.
3.8 Starting up for the first time
After all the connections have been made and checked, the following steps
must be taken:
1. Turn on the filter pump. Check for leaks and make certain that the
water flows from and to the swimming pool.

- 10 -
2. Connect the current to the heat pump and set the switch to ON. The
appliance will start up after the time delay (see below) has elapsed.
3. After a few minutes check whether the air being expelled from the
appliance is cooler.
4. Leave the appliance and filter pump in operation 24 hours per day until
the desired water temperature has been reached. At this point the heat
pump ceases operation. The appliance will now start up again
automatically (as long as the filter pump is in operation) whenever the
swimming pool temperature falls to 1 degree below the programmed
temperature.
Depending on the initial temperature of the swimming pool water and the
air temperature, several days may be needed to bring the water up to the
temperature required. Covering the swimming pool properly can
considerably shorten this period.
Time Delay – the appliance is fitted with built-in start-up delay of 3 minutes
as protection for the electronics and to increase the life of the contacts.
After this interval, the appliance will restart automatically. Even a brief
interruption in the flow of current will activate this delay and thus prevent
the appliance from starting up immediately. Additional interruptions in the
current during this delay will have no influence on the 3-minute
countdown.
3.9 Condensation
The intake air is cooled significantly as a result of the operation of the heat
pump when heating the swimming pool water, and water may condense on
the fins of the evaporator. When humidity is high, this could even amount
to several litres per hour. This is sometimes erroneously seen as a water
leak.

6. Maintenance
6.1 Maintenance
(1) You should check the water supply system regularly to avoid the air
entering the system and occurrence of low water flow, because it would
reduce the performance and reliability of HP unit.
(2) Clean your pools and filtration system regularly to avoid the damage of
the unit as a result of the dirty of clogged filter.
(3) You should discharge the water from bottom of water pump if HP unit
will stop running for a long time (specially during the winter season).
(4) In another way, you should check the unit is water fully before the unit
start to run again.
(5) After the unit is conditioned for the winter season, he is preconize to
cover the heat pump with special winter heat pump.
(6) When the unit is running, there is all the time a little water discharge
under the unit.
(7) The location of chemical’s instruction to your system is also critical to
the heater’s life.
If an automatic chlorinator or brominates is used, it must be located
downstream of the heater.
6.2 Refrigerant pressure
For checking the unit under running model, make sure there is refrigerant
pressure gauge which shows working condition of unit. The following
mapping table shows the number of refrigerant pressure and unit working
condition. If there is big difference between them, the machine is probably
malfunctioning.
