Installation and connection

Attention:
Please observe the following rules when installing the heat pump:

1. Any addition of chemicals must take place in the piping located downstream from the heat pump.
2. 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.

3.1 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 filters
The unit may be installed in virtually any outdoor location as long as the specified minimum distances to other objects are maintained. Please consult your installer for installation with an indoor pool.

ATTENTION: Never install the unit in a closed room with a limited air volume in which the air expelled from the unit will be reused, or close to shrubbery 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.

3.2 Initial operation

Note: In order to heat the water in the pool (or hot tub), the filter 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.

3.3 Electrical connection
Before connecting the unit, verify that the supply voltage matches the operating voltage of the heat pump.

The RCD plug has been included with a power cable, which can offer electrical protection.

Attention:

Ensure the power plug is secure the plug is not secure, it may cause an electric shock, overheating, or fire|

Never pull out the power plug during operation
Otherwise, it 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.

After all, connections have been made and checked, carry out the following procedure:

1. Switch on the filter pump. Check for leaks and verify that water is flowing from and to the swimming pool.
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 turn off the filter pump, the unit should also turn off automatically. ending on the initial temperature of the water in the swimming pool and the air temperature, it may take some time to heat the water to the desired temperature. A good swimming pool cover can dramatically reduce the required ength of time.

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.
If first power on or additional power interruptions, the heat pump starts 10s later after pressing ‘ON/OFF’ button.

3.4 Condensation
The air drawn into the heat pump is strongly cooled by the operation of the heat pump for heating the pool water, which may cause condensation on the ins of the evaporator. The amount of condensation may be as much as several litters per hour at high relative humidity. This is sometimes mistakenly regarded as a water leak. Please you can use the drainage jet and hose at the bottom of the machine to drain the condensation water. See below.

Electrical wiring

4.1 Swimming pool heat pump wiring diagram

NOTE:

1. Above electrical wiring diagram only for your reference, please subject machine posted the wiring diagram.
2. The swimming pool heat pump must be connected to the ground wire well, although the unit heat exchanger is electrically isolated from the rest of the unit.  rounding the unit is still required to protect you against short circuits inside the unit. Bonding is also required. Disconnect: A disconnecting means (circuit reaker, fused or un-fused switch) 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 the power at the unit while the unit is being serviced.
