2. Installation and connection
ATTENTION:
Please pay attention to the following rules when installing the heat pump:
1. Any addition of chemicals must be carried out at the piping located downstream from the heat pump.
2. Always hold the heat pump upright. If it has been held at certain angle more than 30°, wait at least
24 hours before starting the heat pump.
2.1 Location of your heat pump
The heat pump will work properly in any desired location as long as the following three factors are present:
1. Fresh air –2. Electricity –3. Swimming pool water
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 at a windy location does not present any problem at all, unlike the situation with a gas heater.
ATTENTION:
Never install the heat pump in a closed room with limited air volume in which the air discharged from the
heat pump will be reused, or close to shrubbery that might block the air inlet. Such locations impair the
continuous supply of fresh air, may reduce the running efficiency and possibly prevent sufficient heat output.
2.2 Initial operation
Note: In order to heat your pool water, the water pump must run firstly to make the water circulated
through the heat pump.
Your heat pump will not start up if the water is not circulating.

8
2.3 Hose connection
Notes:
There are 2 hoses and 2 clamps supplied by the manufacturer and put in the accessories package.
The upper connection port at heat pumps right side is for water outlet, and the lower port is for water
inlet.
2.4 Electrical connection
Before connecting the heat pump, make sure that the supply voltage matches the operating heat pumps
voltage. Theres RCD plug that equipped with power cable, it help to offer a full electrical protection.

9
ATTENTION:
Make sure the power plug is
secured
If the plug is not secure, it may cause
an electric shock, over-heating or fire
Never pull out the power plug when
your heat pump is running
Such improper operation may
cause an electric shock or a fire due
to over-heating.
Never use damaged electric wires
or unspecified electric wires.
Otherwise it may cause an electric
shock or a fire.
When all connections have been completed and checked, carry out the following procedure:
(1). Switch on the water pump. Check for leakage and verify that water is flowing incoming and outgoing to the
swimming pool.
(2). Connect power to the heat pump and press the On/Off button on the control panel. The heat
Pump 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 cool (The mini heat pump can only
make heating, when starts up, the running mode is heating as default).
(4). When turn off the water pump, the unit should also turn off automatically.
Depending on the initial temperature of the pool water and ambient air temperature, it may take long time to
heat the water to your desired temperature. An appropriate swimming pool cover can dramatically reduce the
heating time and preserve the heat from losing;
Time delay - The heat pump has a built-in 3-minute start-up delay to protect the circuitry and avoid excessive
restarting. The unit will restart automatically after this time delay expires.
2.5 Condensation
The air suctioned into the heat pump will be cooled to be a very low temperature by the evaporation process
of your heat pumps refrigerant, at its heating mode. This may cause condensation on fins of the evaporator,
which might be as much as several litters per hour at high relative humidity.
Sometimes users may treat this phenomenon as water leakage, while this is quite normal and no need to do
anything.

3. Wiring circuit diagram
Suitable for models: FO045HS, FO061HS
NOTES:
(1) Above wiring circuit diagram is for reference only, due to consideration of universal use, there might be some
difference from the actual circuit diagram, please refer to the one stuck on your heat pump.
(2) Ground wire of the swimming pool heat pump must be connected well, although the heat pumps heat
exchanger has been already electrically isolated from the rest of the unit. Grounding the unit is still required to
prevent users from electric shock or unit damage by short circuits. Bonding is also required.
Disconnect: A disconnect (circuit breaker, fused or un-fused switch) should be installed at the position readily
accessible from the heat pump unit. This is common practice for both commercial and residential heat pumps.
It prevents the unattended equipment from remotely-energizing and permits to turn off the power supply
when the unit is being serviced or at maintenance.
