WARNING!
Risk of fire and explosion through leaking finned heat exchanger!
The refrigerant circuit of the finned heat exchanger contains highly pressurised, easily flammable, odourless
gas. Risk of fire and explosion in the event of uncontrolled gas leakage.
- Action of filling gas must be conducted by professional with R32 operating license.
- Keep the heat pump away from heat sources and naked flames.
- Do not drill into or scorch the heat pump.
- Do not use any objects apart from those permitted by the manufacturer to speed up the defrosting process.
- Immediately shut off the heat pump if you suspect a gas leakage.
- The refrigerant is odourless. Always keep ignition sources away from the installation site of the heat pump.
- Contact an authorized expert if you suspect a gas leakage.
WARNING!
Risk of electric shock!
A faulty electrical installation or a mains voltage that is too high can lead to electric shock.
- Have the installation, initial start-up and maintenance of the heat pump carried out by authorized technician
only.
- Please always cut the power supply if you want to open the cabinet to reach inside the heat pump as there is
high voltage electricity inside.
- Only start work on the heat pump after checking all safety regulations.
- Only connect the heat pump if the mains voltage from the power socket matches the voltage indicated on
the rating plate.
- Do not operate the heat pump if there is visible damage or the mains cable or the mains plug is defective.
- Do not open the housing. Leave repairs to qualified specialists. Liability and warranty claims are excluded in

- 2 -
the event of repairs carried out on your own, improper operation.
- Ensure that children do not insert any objects into the fan blade and heat pump.
- Ensure that the electrical system to which the heat pump is connected has an earth conductor.
- If the unit would be installed where is vulnerable to lightning stroke, lightning protection
measurements must be carried out.
ATTENTION!
- The manufacturer declines any responsibility for the damage caused with the people,objects and of the
errors due to the installation that disobey the manual guideline. Any use that is without conformity at the
origin of its manufacturing will be regarded as dangerous.
- Please always keep the heat pump in the ventilation place and away from anything which could cause fire.
- Don’t weld the pipe if there is refrigerant inside machine. Please keep the machine out of the confined space
when make gas filling by the authorized technician.
- Please always empty the water in heat pump during winter time or when the ambient temperature drops
below 0℃, or else the Titanium exchanger will be damaged because of being frozen, in such case, it will be out
of warranty for this machine.

3.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.

- 5 -
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 power cable, which can offer electrical protection.
Attention:
Ensure the power plug is secure
If the plug is not secure, it may cause
an electric shock, over-heating 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.
Depending 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 length 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 fins 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 machine to drain the condensation water.
See below.

4.Electrical wiring
4.1 Swimming pool heat pump wiring diagram

- 8 -
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 ground wire well, although the unit 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) 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.
5. Display controller operation
5.1 The interface of LED wire controller
* When the heat pump is running or standby, the display shows the water inlet temperature.

6.2 Other Malfunctions and Solutions (No display on LED wire controller)
7. 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 HP unit.
(2) Clean your pools and filtration system regularly to avoid the damage of the unit as a result of the dirty of
clogged filter.
(3) You should discharge the water from heat pump if it will stop running for a long time (especially during the
winter season).
(4) In another way, you should check the unit is water fully before the unit start to run again.
(5) When the unit is running, there is all the time a little water discharge under the unit.
