WARNINGS CONCERNING APPLIANCES CONTAINING REFRIGERANT R32
R32 refrigerant is classed under category A2L as mildly flammable.
Do not release R32 fluid into the atmosphere. These are fluorinated greenhouse gases, covered by the Kyoto
Protocol, with a Global Warming Potential (GWP) of 675 (European regulation EU 517/2014).
The appliance must be stored in a well-ventilated location away from all ignition sources.
Install the unit outdoors. Do not install the unit indoors or in an enclosed and non-ventilated outdoor location.
Do not use means for accelerating the defrosting or cleaning process other than those recommended by the
manufacturer.
The appliance must be stored in a room without any permanent ignition source (such as open flames,
operating gas appliance or operating electric heating).
Do not perforate or incinerate.
Please note that R32 refrigerant may give off a certain odour.
In order to comply with the applicable standards and regulations in terms of the environment and installation,
in particular French decree No. 2015-1790 and/or European regulation EU 517/2014, a leak test must be
performed on the cooling circuit at least once a year. This operation must be carried out by a specialist certified
to test cooling appliances.
Please keep the display controller in a dry area, or well close the insulation cover to protect the display
controller from being damaged by humidity.
INSTALLATION AND MAINTENANCE
The appliance may not be installed close to combustible materials, or the air duct inlet of an adjacent building.
With some appliances, it is essential to fit a "protection grid"-type accessory if the unit is installed in an area
with uncontrolled access.
During installation, troubleshooting and maintenance, pipes may not be used as steps: the pipe could break
under the weight, spilling refrigerant and possibly causing serious burns.
When servicing the appliance, the composition and state of the heat transfer fluid must be checked, as well as
the absence of any traces of refrigerant.
During the annual appliance sealing test in accordance with applicable legislation, the high and low pressure
switches must be checked to ensure that they are securely fastened to the refrigerant circuit and that they cut
off the electrical circuit when tripped.
During maintenance work, ensure there are no traces of corrosion or oil around the cooling components.
Before beginning work on the cooling circuit, stop the appliance and wait for a few minutes before fitting the
temperature and pressure sensors. Some elements such as the compressor and piping may reach temperatures
in excess of 100°C and high pressures with the consequent risk of severe burns.
Do not braze or weld the pipe if there is refrigerant inside machine. Please do not charge the gas when in a
confined space.
MAINTENANCE : WARNINGS CONCERNING APPLIANCES CONTAINING R32 REFRIGERANT
Area check
Before starting work on systems containing flammable refrigerants, safety checks must be carried out to
guarantee a minimal ignition risk.

3
Work procedure
The work must be carried out according to a controlled procedure in order to reduce the risks of releasing a
flammable gas or vapour while working.
General work area
All maintenance staff and other personnel working in the surrounding area must be made aware of the work
carried out. Work conducted in enclosed areas must be avoided.
Check for the presence of refrigerant
The area must be analysed using a suitable refrigerant detector before and during work so that the technician is
informed of the presence of a potentially toxic or flammable atmosphere. Check that the leak detection
equipment used is suitable for use with all refrigerants concerned, i.e. that it does not cause a spark, is
correctly isolated or is entirely safe.
Check for the presence of a fire extinguisher
If work must be carried out on the cooling equipment or any part associated therewith at a certain
temperature, suitable fire extinguishing means must be within reach. Place a dry chemical fire extinguisher or
CO2fire extinguisher near the work area.
No source of ignition
No person carrying out work on a cooling system involving exposing the piping may use any ignition source,
which could create a fire or explosion risk. All possible ignition sources, in particular cigarettes, must not enter
within a sufficient perimeter of the installation, repair, removal or disposal site, in the event that refrigerant
could be released into the surrounding space. Before starting the work, the area around the equipment must
be examined to check for all fire or ignition risks. "No smoking" signs must be displayed.
Area ventilation
Before accessing the unit in any manner whatsoever with the intention of performing any maintenance task,
check that the area is open and well-ventilated. Suitable ventilation must be provided throughout the
maintenance task to allow any refrigerant that could be released into the atmosphere to be safely dispersed.
Refrigeration equipment check
The manufacturer's recommendations in terms of care and maintenance must always be complied with.
When replacing electric components, check that components used are of the same type and category as those
recommended/approved by the manufacturer. When in doubt, contact the manufacturer's technical
department for assistance.
The following checks must be applied to installations using flammable refrigerants:
-the markings on the equipment must remain visible and legible; any illegible markings or signs must be rectified;
-the hoses or components of the cooling circuit are installed in a position where they are unlikely to be exposed to
any substance capable of corroding the components containing refrigerant, unless the components are made from
materials that are typically corrosion-proof or correctly protected from such corrosion.
Electric component check
The repair and maintenance of electric components must include initial safety checks and component
inspection procedures. If a defect capable of jeopardising safety arises, no power supply must be connected to
the circuit until the problem has been completely resolved. If the defect cannot be rectified immediately and if
maintenance work must continue, an appropriate temporary solution must be found. This must be reported to
the equipment's owner so that all persons concerned are made aware.
The repair and maintenance of electric components must include the following initial safety checks:

4
-the capacitors are discharged: this must be carried out safely to prevent all risks of ignition;
-no electric component or live wiring is exposed while charging, overhauling or draining the system;
-the system must be grounded at all times.
Repair of insulated components
When repairing insulated components, all power sources must be disconnected from the equipment on which
the work is being carried out before removing the insulating cover, etc. If the equipment must be powered
during maintenance work, a leak detector must continuously monitor for leaks at the most critical point in
order to report any potentially hazardous situation.
Particular attention must be paid to the following points to ensure that, when performing work on the electric
components, the housing is not altered to the point of affecting the protection rating. This includes damaged
wires, an excessive number of connections, terminals that do not comply with the original specifications,
damaged seals, incorrect installation of the cable glands, etc.
Make sure that the appliance is properly fixed.
Make sure that the seals or insulating materials are not deteriorated to the point that they no longer prevent a
flammable atmosphere from penetrating the circuit. Spare parts must be compliant with the manufacturer’s
specifications.
Repair of intrinsically safe components
Do not apply any permanent electric capacitance or induction charge to the circuit without checking that it
does not exceed the allowed voltage and intensity for the equipment being used.
Typically safe components are the only types on which work can be carried out in the presence of a flammable
atmosphere when live. The test appliance must fall under a suitable classification.
Only replace components with parts specified by the manufacturer. Other parts could cause the refrigerant to
leak and ignite in the atmosphere.
Wiring
Check that the wiring shows no signs of wear, corrosion, excessive pressure, vibration, cutting edges or any
other detrimental environmental effect. The check must also take into account the effects of ageing or
continuous vibrations caused by sources such as compressors or fans.
Detection of flammable refrigerant
Under no circumstances must potential ignition sources be used to search for or detect refrigerant leaks. A
halide torch (or any other detector using a naked flame) must not be used.
The following leak detection methods are considered to be acceptable for all cooling systems.
Electronic leak detectors can be used to detect refrigerant leaks; however, in the case of flammable refrigerants,
the sensitivity level may not be suitable or recalibration may be necessary. (The detection equipment must be
calibrated in an area devoid of refrigerant). Check that the detector is not a potential ignition source and is
appropriate for the refrigerant used. The leak detection equipment must be adjusted to a percentage of the
refrigerant's LFL and must be calibrated according to the refrigerant used. The appropriate gas percentage (25%
at most) must be confirmed.
Leak detection fluids are also suited for use with most refrigerants, however the use of detergents containing
chlorine must be avoided since it could react with the refrigerant and cause corrosion to the copper piping.
If a leak is suspected, all naked flames must be removed/extinguished.
If a refrigerant leak is detected and requires soldering, the entire quantity of refrigerant must be removed from
the system or isolated (by way of shut-off valves) in part of the system located away from the leak.
Removal and discharge
When accessing the cooling circuit to carry out repairs, or for any other reason, conventional procedures must
be employed. However, for flammable refrigerants, the recommendations must be complied with in order to
take account of the product's flammability. The following procedure must be followed:

5
remove the refrigerant;
purge the circuit with an inert gas (optional for A2L);
drain (optional for A2L);
purge with an inert gas (optional for A2L);
open the circuit by cutting or soldering.
The refrigerant charge must be recovered in suitable recovery cylinders. For appliances containing flammable
refrigerants other than A2L refrigerants, the system must be bled with nitrogen devoid of oxygen to make the
appliance suitable for receiving flammable refrigerants. You may need to repeat this process several times.
Compressed air or oxygen must not be used to purge cooling systems.
Loading procedures
Check that the vacuum pump outlet is not located in the vicinity of any potential ignition source and that
ventilation is provided.
In addition to conventional charging procedures, the following requirements apply.
Check that there is no possibility of cross-contamination between the different refrigerants when using
charging equipment. Hoses or lines must be as short as possible to reduce the quantity of refrigerant contained
therein.
Cylinders must be kept in an appropriate position, in accordance with the instructions.
Check that the cooling system is grounded before charging the system with refrigerant.
Label the system once charging is complete (if this is not already the case).
Pay close attention to not overfilling the cooling system.
Before recharging the system, carry out a pressure test using a suitable purge gas. The system must be
examined to make sure there are no leaks after the charging operation and before commissioning. A follow-up
leak test must be carried out before leaving the site.
Dismantling
Before dismantling, the technician must familiarise himself/herself with the equipment and its specifications.
We highly recommend carefully recovering all refrigerants. Before this, oil and refrigerant samples must be
taken if analyses are to be carried out before any other use of the recovered refrigerant. Check for the presence
of a power supply before starting work.
1. Familiarise yourself with the equipment and how it operates.
2. Electrically isolate the system.
3. Before starting work, check the following points:
-mechanical handling equipment is available if needed to handle the refrigerant cylinders;
-all personal protective equipment is available and used correctly;
-the recovery process is followed at all times by a cognizant person;
-the recovery cylinders and equipment comply with the relevant standards.
1. Drain the cooling system where possible.
2. If a vacuum cannot be created, install a manifold in order to be able to remove the refrigerant from various
locations within the system.
3. Make sure that the cylinder is located on the scales before starting recovery operations.
4. Start the recovery unit and operate as per its instructions.
5. Do not overfill the cylinders (no more than 80% of the volume must be filled with liquid).
6. Do not exceed the maximum working pressure of the cylinder, even temporarily.
7. When the cylinders have been filled correctly and the process is complete, check that the cylinders and the
equipment are quickly removed from the site and that the alternative shut-off valves on the equipment are
closed.
8. The recovered refrigerant must not be charged in another cooling system, unless it has been cleaned and inspected.
TROUBLESHOOTING
All brazing must be carried out by qualified brazers.
Replacement pipes must always be made of copper in compliance with standard NF EN 12735-1.
Leak detection; pressure test:

6
-never use oxygen or dry air, risk of fire or explosion,
-use dry nitrogen or the mixture of nitrogen and refrigerant indicated on the information plate,
-the test pressure for both the high and low pressure circuits must not exceed 42 bar in cases where the appliance
is equipped with the optional pressure gauge.
The high pressure circuit pipes are made of copper and have a diameter equal to or greater than 1’’5/8. A
certificate as indicated in§2.1 in compliance with standard NF EN 10204 must be requested from the supplier
and filed in the installation’s technical file.
Technical data relative to the safety requirements of the various applicable directives are indicated on the
information plate. All this information must be recorded in the appliance’s installation manual, which must be
kept in its technical file: model, code, serial number, maximum and minimum OT, OP, year of manufacture, CE
marking, manufacturer’s address, refrigerant and weight, electrical parameters, thermo-dynamic and acoustic
performance.
LABELLING
The equipment must be labelled so as to specify that it is out of order and that the refrigerant has been drained.
The label must be dated and signed.
For appliances containing a flammable refrigerant, check that labels are placed on the equipment stating that it
contains a flammable refrigerant.
RECOVERY
When draining the refrigerant for maintenance or decommissioning, best practices should be followed in order
to safely drain all of the refrigerant.
When transferring refrigerant to a cylinder, make sure that you use a recovery cylinder that is compatible with
the refrigerant. Make sure that the correct number of cylinders are provided for recovering all of the refrigerant.
All cylinders used must be intended for the recovery of refrigerant and must be labelled for this specific
refrigerant. The cylinders must be equipped with a vacuum valve and a stop gate in good working order. Empty
collection cylinders are drained and, where possible, cooled before recovery.
The recovery equipment must be in good working order, the instructions for using the equipment must be
within reach and the equipment must be compatible for use with the refrigerant concerned, including, where
appropriate, a flammable refrigerant. Moreover, a set of calibrated scales must be available and in good
working order. The pipework must be complete, have no leaks or disconnected connectors, and must be in
good condition. Before using the recovery unit, check that it is in good working order, that it has been well
maintained and that the associated electric components are sealed so as to prevent any risk of fire in the event
of refrigerant being released. If you have any doubts, contact the manufacturer.
The recovered refrigerant must be sent to the refrigerant supplier in its recovery cylinder with a waste transfer
note. Do not mix different refrigerants in the recovery units, and in particular in the cylinders.
If the compressor has been removed or if oil from the compressor has been drained, check that the refrigerant
has been completely removed to prevent it from mixing with the lubricant. The draining process must be
carried out before returning the compressor to the supplier. Only the electric heater of the compressor body
can be used to accelerate this process. This operation can be carried out safely once all liquids within the
system have been drained.
RECYCLING
This symbol is required by the European directive DEEE 2012/19/EU (directive on
waste electrical and electronic equipment) and means that your appliance must not
be thrown into a normal bin. It will be selectively collected for the purpose of reuse,
recycling or transformation. If it contains any substances that may be harmful to the
environment, these will be eliminated or neutralised. Contact your retailer for

3. Installation and connection
3.1 Notes
The factory supplies only the heat pump. All other components, including a bypass if necessary, 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. Install a bypass if the water flow from the swimming pool pump is more than 20% greater than the
allowable flow through the heat exchanger of the heat pump.
3. Install the heat pump above the water level of the swimming pool.
4. Always place the heat pump on a solid foundation and use the included rubber mounts to avoid
vibration and noise.
5. 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 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 (see drawing below). Please consult your installer for installation with an indoor
pool. Installation in a windy location does not present any problem at all, unlike the situation with a gas
heater (including pilot flame problems).
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.
See the drawing below for minimum dimensions.

13
3.3 Check-valve installation
Note: If automatic dosing equipment for chlorine and acidity (pH) is used, it is essential to protect the heat
pump against excessively high chemical concentrations which may corrode the heat exchanger. For this
reason, equipment of this sort must always be fitted in the piping on the downstream side of the heat pump,
and it is recommended to install a check-valve to prevent reverse flow in the absence of water circulation.
Damage to the heat pump caused by failure to observe this instruction is not covered by the warranty.
3.4 Typical arrangement
Note: This arrangement is only an illustrative example.

14
3.5 Adjusting the bypass
How to get the optimum water flow.
Please turn on the heat pump under heating function, firstly close the by-pass then open it slowly to start the
heat pump (the machine can't start running when the water flow is insufficient)
Continue to adjust the by-pass, at the meantime to check the Inlet water temp. & Outlet water temp., it will
be optimum when the difference is around 2 degree.
3.6 Electrical connection
Note: Although the heat pump is electrically isolated from the rest of the swimming pool system, this
only prevents the flow of electrical current to or from the water in the pool. Earthing is still required
for protection against short-circuits inside the unit. Always provide a good earth connection.The
installer must consult the electricity provider if necessary and ensure that the equipment is
connected correctly to an electricity network with impedance under 0.095 ohm.
Warning : Before any work inside the appliance, you must cut the appliance’s electricity supply as there is a
risk of electric shock which may cause material damage, serious injury or even death.
• Incorrectly tightened terminals may cause the terminal box to heat up, which can invalidate
the warranty.
• Only a qualified and experienced technician is authorised to carry out cabling work within the
appliance or to replace the power cord.
Before connecting the unit, verify that the supply voltage matches the operating voltage of the heat pump.
It is recommended to connect the heat pump to a circuit with its own fuse or circuit breaker (slow type; curve
D) and to use adequate wiring.
Connect the electrical wires to the terminal block marked ‘ POWER SUPPLY ’.
A second terminal block marked ‘WATER PUMP ’ is located next to the first one. The filter pump (max. 5 A
0 V) can be connected to the second terminal block here. This allows the filter pump operation to be
controlled by the heat pump.
Out In
Heat Pump
Please take below steps to adjust
the by-pass:
1. Valve 1 wide open. Valve 2 &
valve 3 closed.
2. Slowly open valve 2 & valve 3 by
half, then close the valve 1 slowly
to increase the water flow to valve 2
& valve 3.
3. If it shows ‘ON’ or ‘EE3’ on
display, it means the water flow into
heat pump is not enough, then you
need adjust the valves to increase
the water flow through the heat
pump.

3.7 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.
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 , if not, then adjust the flow
switch.
5. Allow the heat pump and the filter 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 filter pump is running) whenever the swimming pool water temperature drops 2 degree below the set
temperature.
Depending on the initial temperature of the water in the swimming pool and the air temperature, it may take
several days to heat the water to the desired temperature. A good swimming pool cover can dramatically
reduce the required length of time.
Water Flow Switch:
It is equipped with a flow switch for protecting the HP unit running with adequate water flow rate .It will turn o
n when the pool pump runs and shut it off when the pump shuts off. If the pool water level higher than 1 m
above or below the heat pump’s automatic adjustment knob, your dealer may need to adjust its initial start
up.
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.
3.8 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 litres per hour at high relative humidity. This is sometimes mistakenly regarded as a water
leak.
