3. Installation and connection:
3.1 Notes: Upon purchase you will receive your complete Heat Pump. All other components, including
a bypass if necessary, must be provided by the user or the installer.
Attention:
Please observe the following rules when installing the heat pump:
1. Any addition of automated chemicals must take place in the piping located downstream from the
heat pump.
2. Install a bypass if the water flow from the swimming pool pump is more than 20% greater than the
allowable flow through the heat exchanger of the heat pump.
3. Install the heat pump below the water level of the swimming pool. Unless a one way check valve is
used in the plumbing circuit to avoid siphoning back and air locks.
4. Always place the heat pump on a solid foundation and use the included rubber mounts to avoid
vibration and noise.
5. Always hold the heat pump upright. If the unit has been held at an angle, wait at least 24 hours
before starting the heat pump.
3.2 Heat pump location
The unit will work properly in any desired location as long as the following three items are present:
1. Fresh air – 2. Electricity – 3. Swimming pool filtration
The unit may be installed in virtually any outdoor location as long as the specified minimum distances to
other objects are maintained (see drawing below). Please consult your installer for installation with an
indoor pool. Installation in a windy location does not present any problem at all, unlike the situation with a
gas heater (including pilot flame problems).
ATTENTION: Never install the unit in a closed room with limited air volume in which, the air expelled from
the unit will be reused, or close to shrubbery/plant life that could block the air inlet. Such locations impair
the continuous supply of fresh air, resulting in reduced efficiency and possibly preventing sufficient heat
output. Heat Pumps require fresh air & maximum ventilation to be more productive.
See the drawing below for "ABSOLUTE" minimum dimensions.

-6-
3.3 Distance from your swimming pool
The heat pump is normally installed within a perimeter area extending 7.5 m from the swimming pool. But,
at least 2m away from the pool so a person cannot touch the pool and the heat pump at the same time, as
this would lead to electrical safety concerns.
The greater the distance from the pool, the greater the heat loss in the pipes. As the pipes are mostly
underground, the heat loss is low for distances up to 30 m (15 m from and to the pump; 30 m in total)
unless the ground is wet or the groundwater level is high. A rough estimate of the heat loss per 30 m is
0.6 kWh (2,000 BTU) for every 5 ºC difference between the water temperature in the pool and the
temperature of the soil surrounding the pipe. This increases the operating time by 3% to 5%.
3.4 Check-valve installation
Note: If automatic dosing equipment for chlorine and acid (pH) is used, it is essential to protect the heat
pump against excessively high chemical concentrations which may corrode the heat exchanger. For this
reason, equipment of this sort must always be fitted in the piping on the downstream side of 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 failure to observe this instruction is not covered by the WARRANTY.

-7-
Heat Pump
In
Out
From pool
To pool
Use the following procedure to adjust the
bypass:
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 to adjust the
valves to increase the water flow
through the heat pump.
3.5 Typical arrangement
Note: This arrangement is only an illustrative example.
3.6 Adjusting the bypass
Note: Operation without a bypass or with improper bypass adjustment may result in sub-optimal
heat pump operation and possibly damage to the heat pump, which renders the warranty null and
void.

-8-
3.7 Electrical connection
Note: Although the heat pump is electrically isolated from the rest of the swimming pool system,
this only prevents the flow of electrical current to or from the water in the pool. Earthing is still
required for protection against short-circuits inside the unit. Always provide a good earth
connection.
We also recommend that electrical installation is conducted by a licensed electrician.
Before connecting the unit, verify that the supply voltage matches the operating voltage of the heat pump.
It is recommended to connect the heat pump to a circuit with its own fuse or circuit breaker and adequate
wiring.
Connection: Open the terminal box on the side panel.
Connect the electrical wires to the terminal block marked ‘POWER SUPPLY’
A second terminal block marked ‘WATER PUMP ’ is located next to the first one. If you are using a
secondary pump to circulate water from the pool to the heat pump this pump can be connected to the
second terminal block here. This allows the filter pump operation to be controlled by the heat pump.
NOTE: Any damage caused or PCB`s damaged by doing this will VOID the warranty. Filtration and
Sanitsation may be adversely affected if ambient temperature are higher than set water temperature, thus
no need for the heat pump to come on so no need for the filtration to come on. We strongly recommend
that the pump is not connected to the heat pump for control.
3.8 Initial operation
Note: In order to heat the water in the pool (pond or spa), the filtration pump must be running to
cause the water to circulate through the heat pump.
The heat pump will not start up if the water is not circulating through it.
After all connections have been made and checked, carry out the following procedure:
1. Switch on the filtration pump. Check for leaks and verify that water is flowing from and to the swimming
pool at an adequate flow rate.
2. Connect power to the heat pump and press the On/Off button on the electronic control panel. The
unit will start up, after the time delay expires (see below).
3. After a few minutes, check whether the air blowing out of the unit is cooler.
4. When turning off the filtration pump, the unit should also turn off automatically, if not, then adjust the
flow switch.
5. Allow the heat pump and the filtration pump to run 24 hours a day until the desired water temperature is
reached. The heat pump will stop running at this point. After this, it will restart automatically (as long as
the filter pump is running) whenever the swimming pool water temperature drops 2 degree below the
set temperature.
Depending on the initial temperature of the water in the swimming pool and the air temperature, it may take
several days to heat the water to the desired temperature. A good swimming pool cover can dramatically
reduce the required length of heating time & is highly recommended as standard.
Water Flow Switch:
The heat pump is fitted with an automatic flow switch to protect the heat pump from inadequate water flow.
If the pool water level is higher than 1m above or below the heat pump’s automatic adjustment knob,
your dealer may need to adjust its initial start up.

-9-
Time delay:
The heat pump has a built-in 3-minute start-up delay to protect the circuitry and avoid excessive contact
wear. The unit will restart automatically after this time delay expires. Even a brief power interruption will
trigger this time delay and prevent the unit from restarting immediately. Additional power interruptions
during this delay period do not affect the 3-minute duration of the delay.
3.9 Condensation
The air drawn into the heat pump is strongly cooled by the operation of the heat pump for heating the pool
water, this may cause condensation on the fins of the evaporator. The amount of condensation may be as
much as several litres per hour at high relative humidity. This is sometimes mistakenly regarded as a water
leak. If there is excessive water coming from your heat pump please see your installer.

5. Electrical Wiring
5.1 Electrical wiring diagram
Model CHP055_Trad_C
NOTE:
(1) Above electrical wiring diagram is only for your reference, please consult the manufacturer for repair
advice.
(2) The swimming pool heat pump must be connected to earth, although the units heat exchanger is
electrically isolated from the rest of the unit. Grounding the unit is still required to protect you against short
circuits inside the unit .Bonding is also required.
Disconnect: A disconnect means (circuit breaker, fused or un-fused switch or un-plug) should be located
within sight of and readily accessible from the unit. This is common practice on commercial and residential
heat pumps. It prevents remotely-energizing unattended equipment and permits turning off power at the
unit while the unit is being serviced.
