Thank you for using our heat pump for the heating of your spa, it will heat your spa water
and keep a constant temperature when the ambient air temperature is at -25~43℃
ATTENTION: This manual includes all the necessary information about the use and
the installation of your heat pump.
The installer must read the manual and attentively follow the instructions of implementation
and maintenance.
The installer is responsible for the installation of the product and should follow all the
instructions of the manufacturer and the regulations in application. Incorrect installation
against the manual implies the exclusion of the entire guarantee.
The manufacturer declines any responsibility for the damage caused by people, objects and
errors due to the installation against the manual. Any use that isn’t in accordance with the
origin
of
its
manufacturing
will be regarded
as
dangerous.
WARNING：
Do not use means to accelerate the defrosting process, other than those recommended
by the manufacturer.
The appliance shall be stored in a room without continuously operating ignition sources
(for example: open flames, an operating gas appliance or an operating electric heater.)
Do not pierce or burn.
Be aware that refrigerants may not contain an odour.
This heat pump shall be installed, operated and stored in a open room larger than 3 m³.
Note the manufacturer may provide other suitable examples or may provide additional
information about the refrigerant odour.
WARNING: If you power off heat pump, please empty the water in heat pump always
during winter time or when the ambient temperature drops below 0℃, or else the titanium
heat exchanger will be damaged because of being frozen, in such case, your warranty
will be lost.
WARNING: Please always cut the power supply if you want to open the cabinet to reach
inside the heat pump, because there is high voltage electricity inside.
WARNING: Please keep the display controller in a dry area, or close the insulation cover
to protect the display controller from being damaged by humidity.

1. Dimensions
2. Installation and connection
2.1. Notes
The factory only supplies the heat pump. All other components must be provided by the
user or the installer.
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 place the heat pump on a solid foundation and use the provided rubber
feet to avoid vibration and noise.
3. 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.
2.2. Heat pump’s location
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.
See the drawing below for minimum distances.

2.3. Electrical connection
Note: Earthing is required for protection against short-circuits inside the unit.
Always provide a good earth connection.
Before connecting the unit, verify that the supply voltage matches the required voltage of
the heat pump.
It is recommended to connect the heat pump to a circuit with its own fuse or circuit
breaker.
An auxiliary electric heater and water pump (max. 5 A / 240 V) can be connected to the
terminal block below. This allows the water pump or electric heater to be controlled by
the heat pump.

12 September 2023/ DH [Hier eingeben] Seite 7 von 26
2.4. Initial operation
Note: In order to heat the water in the pool (or hot tub), the water 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.
After all connections have been made and checked, carry out the following procedure:
1. Switch on the water pump. Check for leaks and verify that water is flowing from and to
the 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 you turn off the water pump , the unit should also turn off automatically, if not
adjust the flow switch.
5. Allow the heat pump and the water 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 water pump is running) whenever the pool water
temperature drops 1 degree below the set temperature.
Depending on the initial temperature of the water in the pool and the air temperature, it
may take many hours or even more than one day to heat the water to the desired
temperature. A good pool cover can dramatically reduce the required length of time.
Water Flow Switch:
It is equipped with a flow switch to prevent the heat pump of running with inadequate
water flow rate. It will turn on when the pool pump runs and shuts off when the pump
shuts off. If the pool water level is more than 1m above or below the heat pump’s
automatic adjustment knob, your dealer may need to adjust its initial startup.
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.
2.5. 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 fins of the evaporator. The
amount of condensation may be as much as several liters per hour at high relative
humidity. This is sometimes mistakenly regarded as a water leak.

3. Electrical Wiring

12 September 2023/ DH [Hier eingeben] Seite 9 von 26
NOTE:
(1)The above electrical wiring diagrams are only for your reference, please subject the
heat pump to the posted wiring diagram.
(2)The heat pump must be earthed well.Earthing the unit is still required to protect you
against short circuits inside the unit.
Disconnect: A disconnector (circuit breaker, fused or un-fused switch) should be located
within sight of and easily 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 to the unit while the unit is being serviced.
