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 -20~43℃
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.

3. Installation and connection
3.1 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.
3.2 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.

-6-
3.3 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.

-7-
3.4 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.
3.5 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.

4. Electrical Wiring

-9-
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.
5. Controller’s Operations
LED Display Controller
5.1 Overview
◎The controller is specially designed for the heat pump, with features as below:

8. 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
the heat pump.
(2) Clean your pools and filtration system regularly to avoid the damage of the unit as a result
of a dirty or clogged filter.
(3) You should discharge the water from the bottom of the water pump if the heat pump will
stop running for a long time (specially during the winter season).
(4) On any other moment, you should check if the unit has enough water before the unit
starts to run again.
(5) After the unit is conditioned for the winter season, it is preferred to cover the heat pump
with the special winter heat pump cover.
(6) When the unit is running, there is always a little water discharge under the unit.
