INSTALLATION AND MAINTENANCE
• The appliance may not be installed close to combusble materials, or an air duct
inlet of an adjacent building.
• With some appliances, it is essenal to t protecon grids if the unit is installed in
an area with uncontrolled access.
• During installaon, troubleshoong and maintenance, pipes may not be used as
steps: the pipe could break under the weight, spilling coolant and possibly causing
serious burns.
• When servicing the appliance, the composion and state of the heat transfer uid
must be checked, as well as the absence of any traces of coolant.
• During the appliance’s annual sealing test in accordance with applicable legislaon,
the high and low pressure switches must be checked to ensure that they are
securely fastened to the cooling circuit and that they cut o 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 ng 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.
LABELLING
• Equipment shall be labelled stang that it has been decommissioned and emped
of refrigerant.
• The label shall be dated and signed.
• For appliances containing ammable refrigerants, ensure that there are labels on
the equipment stang the equipment contains ammable refrigerant.
RECOVERING
• When removing refrigerant from a system. either for servicing or decommissioning,
it is recommended good pracce that all refrigerants are removed safely.
• When transferring refrigerant into cylinders, ensure that only appropriate
refrigerant recovery cylinders are employed. Ensure that the correct number of
cylinders for holding the total system charge is available. All cylinders to be used
are designated for the recovered refrigerant and labelled for that refrigerant (i.e.
special cylinders for the recovery of refrigerant). Cylinders shall be complete with
pressure-relief valve and associated shut-o valves in good working order. Empty
recovery cylinders are evacuated and. if possible. cooled before recovery occurs.
• The recovery equipment shall be in good working order with a set of instrucons
concerning the equipment that is at hand and shall be suitable for the recovery
of all appropriate refrigerants including, when applicable, ammable refrigerants.
In addion, a set of calibrated weighing scales shall be available and in good
working order. Hoses shall be complete with leak-free disconnect couplings and in
good condion. Before using the recovery machine, check that it is in sasfactory
working order, has been properly maintained and that any associated electrical
components are sealed to prevent ignion in the event of a refrigerant release.
Consult manufacturer it in doubt.
• The recovered refrigerant shall be returned to the refrigerant supplier in the
correct recovery cylinder, and the relevant waste transfer note arranged. Do not
mix refrigerants in recovery units and especially not in cylinders.
• If compressors or compressor oils are to be removed. ensure that they have been
evacuated to an acceptable level to make certain that ammable refrigerant does
not remain within the lubricant. The evacuaon process shall be carried out prior to
returning the compressor to the suppliers. Only electric heang to the compressor
body shall be employed to accelerate this process. When all is drained from a
system, it shall be carried out safely.

❸ Use
3.1 I Operang principle
Your heat pump uses the calories (heat) in the air to heat up your pool's water. The process to heat your pool's water to
the temperature you want may take a few days as it depends on the weather condions, your heat pump's power and
the dierence between the water temperature and the temperature you want.
The heat pump is ideal for maintaining temperature.
The warmer and damper the air, the beer your heat pump will perform. The outdoor parameters for opmum operaon
are an air temperature of 27°C, a water temperature of 27°C and 80% hygrometry.
Tips: improve your pool's temperature rise and maintenance
• Ancipate the commissioning of your pool far enough in advance before you use it.
• For the temperature rise, set the ltraon pump to connuous operaon (24/24).
• To maintain the temperature throughout the season, switch to “automac” circulaon equal to at least
the water temperature divided by two (the longer this me will be, the more the heat pump will have an
operang range sucient to heat).
• Cover the basin with a sheet (bubble canopy, canvas, etc.) to prevent heat loss.
• Take advantage of a period with mild outdoor temperatures (on average > 10°C at night); your heat pump
will be even more eecve if it runs during the warmest hours of the day.
• Keep the evaporator clean (see § “4.2 I Maintenance”).
• Set the temperature you want and let the heat pump run (adjusng the setpoint to maximum will not
heat the water more quickly).
• Connect the “Heang priority”; the ltraon pump and heat pump operang me will be set according
to requirements.

• Drain the water from the condenser (risk of freezing) by unscrewing the water input and output connectors on the
back of the heat pump,
• In the case of full winterizing for the pool (complete shutdown of the ltraon system, bleed the ltraon circuit
or even pool drainage): ghten the two connectors by one turn to prevent any foreign bodies from geng into the
condenser,
• In the case of winterizing for the heat pump only (shutdown of the heang only, the ltraon keeps running): to not
ghten the connectors but add 2 caps (provided) on the condenser's water inputs and outputs.
• We recommend that you put the aired winterizing micro cover on the heat pump.
4.2 I Maintenance
• It is recommended that the device be general servicing at least on a yearly basis to ensure
proper operaon, maintain performance levels and prevent some potenal failures. These
operaons are carried out at the user's expense, by a technician.
4.2.1 Safety instrucons for appliances containing R32 refrigerant
Area check
• Before starng work on systems containing ammable refrigerants, safety checks must be carried out to guarantee a
minimal ignion risk.
Work procedure
• The work must be carried out according to a controlled procedure in order to reduce the risks of releasing a ammable
gas or vapour while working.
General work area
• All maintenance sta 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 potenally toxic or ammable atmosphere. Check that the leak detecon equipment
used is suitable for use with all refrigerants concerned, i.e. that it does not cause a spark, is correctly isolated or is
enrely safe.
Check for the presence of a re exnguisher
• If work must be carried out on the cooling equipment or any part associated therewith at a certain temperature,
suitable re exnguishing means must be within reach. Place a dry chemical re exnguisher or CO<g-
1776156949>2</g-1776156949> re exnguisher near the work area.
No source of ignion
• No person carrying out work on a cooling system involving exposing the piping may use any ignion source, which
could create a re or explosion risk. All possible ignion sources, in parcular cigarees, must not enter within a
sucient perimeter of the installaon, repair, removal or disposal site, in the event that refrigerant could be released
into the surrounding space. Before starng the work, the area around the equipment must be examined to check for
all re or ignion risks. “No smoking” signs must be displayed.
Area venlaon
• Before accessing the unit in any manner whatsoever with the intenon of performing any maintenance task, check
that the area is open and well-venlated. Suitable venlaon must be provided throughout the maintenance task to
allow any refrigerant that could be released into the atmosphere to be safely dispersed.
Refrigeraon equipment check
• The manufacturer’s recommendaons 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/
EN

16
approved by the manufacturer. When in doubt, contact the manufacturer’s technical department for assistance.
• The following checks must be applied to installaons using ammable refrigerants:
- if an indirect cooling circuit is used, the presence of refrigerant in the secondary circuit must be analysed;
- the markings on the equipment must remain visible and legible; any illegible markings or signs must be reced;
- the hoses or components of the cooling circuit are installed in a posion 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 inial safety checks and component inspecon
procedures. If a defect capable of jeopardising safety arises, no power supply must be connected to the circuit unl
the problem has been completely resolved. If the defect cannot be reced immediately and if maintenance work
must connue, an appropriate temporary soluon 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 inial safety checks:
- the capacitors are discharged: this must be carried out safely to prevent all risks of ignion;
- no electric component or live wiring is exposed while charging, overhauling or draining the system;
- the system must be grounded at all mes.
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 insulang cover, etc. If the equipment must be powered during
maintenance work, a leak detector must connuously monitor for leaks at the most crical point in order to report
any potenally hazardous situaon.
• Parcular aenon 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 aecng the protecon rang. This includes damaged wires,
an excessive number of connecons, terminals that do not comply with the original specicaons, damaged seals,
incorrect installaon of the cable glands, etc.
• Make sure that the appliance is properly xed.
• Make sure that the seals or insulang materials are not deteriorated to the point that they no longer prevent a
ammable atmosphere from penetrang the circuit. Spare parts must be compliant with the manufacturer’s
specicaons.
Repair of intrinsically safe components
• Do not apply any permanent electric capacitance or inducon 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 ammable
atmosphere when live. The test appliance must fall under a suitable classicaon.
• Only replace components with parts specied 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, vibraon, cung edges or any other
detrimental environmental eect. The check must also take into account the eects of ageing or connuous vibraons
caused by sources such as compressors or fans.
Detecon of ammable refrigerant
• Under no circumstances must potenal ignion sources be used to search for or detect refrigerant leaks. A halide
torch (or any other detector using a naked ame) must not be used.
• The following leak detecon 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 ammable refrigerants, the
sensivity level may not be suitable or recalibraon may be necessary. (The detecon equipment must be calibrated
in an area devoid of refrigerant). Check that the detector is not a potenal ignion source and is appropriate for the
refrigerant used. The leak detecon 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 conrmed.
• Leak detecon uids 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 ames must be removed/exnguished.
• If a refrigerant leak is detected and requires soldering, the enre quanty of refrigerant must be removed from the
system or isolated (by way of shut-o 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, convenonal procedures must be
employed. However, for ammable refrigerants, the recommendaons must be complied with in order to take
account of the product’s ammability. The following procedure must be followed:
- remove the refrigerant;
- purge the circuit with an inert gas;
- drain;
- purge with an inert gas;
- open the circuit by cung or soldering.
• The refrigerant charge must be recovered in suitable recovery cylinders. For appliances containing ammable
refrigerants other than A2L refrigerants, the system must be bled with nitrogen devoid of oxygen to make the appliance
suitable for receiving ammable refrigerants. You may need to repeat this process several mes. 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 potenal ignion source and that venlaon
is provided.

17
• In addion to convenonal charging procedures, the following requirements apply.
- Check that there is no possibility of cross-contaminaon between the dierent refrigerants when using charging
equipment. Hoses or lines must be as short as possible to reduce the quanty of refrigerant contained therein.
- Cylinders must be kept in an appropriate posion, in accordance with the instrucons.
- 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 aenon to not overlling 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 aer the charging operaon 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 specicaons. 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 starng work.
1. Familiarise yourself with the equipment and how it operates.
2. Electrically isolate the system.
3. Before starng work, check the following points:
- mechanical handling equipment is available if needed to handle the refrigerant cylinders;
- all personal protecve equipment is available and used correctly;
- the recovery process is monitored at all mes by a cognisant person;
- the recovery cylinders and equipment comply with the relevant standards.
4. Drain the cooling system where possible.
5. If a vacuum cannot be created, install a manifold in order to be able to remove the refrigerant from various locaons
within the system.
6. Make sure that the cylinder is located on the scales before starng recovery operaons.
7. Start the recovery unit and operate as per its instrucons.
8. Do not overll the cylinders (no more than 80% of the volume must be lled with liquid).
9. Do not exceed the maximum working pressure of the cylinder, even temporarily.
10. When the cylinders have been lled correctly and the process is complete, check that the cylinders and the
equipment are quickly removed from the site and that the alternave shut-o valves on the equipment are closed.
11. The recovered refrigerant must not be charged in another cooling system, unless it has been cleaned and inspected.
4.2.2 User maintenance
• Make sure that the lter is not blocked by any foreign bodies.
• Clean the evaporator (for locaon see § “1.3 I Dimensions and marking”) using a so brush and a fresh water spray

❺ Troubleshoong
• Before you contact your reseller, please carry out these few simple checks using the following
tables if a problem occurs.
• If the problem connues contact your reseller.
• : Acons reserved for a qualied technician
5.1 I Device behaviour
The device does
not start heang
straight away
• On start-up, the device remains "paused" for 5 minutes before it starts operang.
• When the setpoint temperature is reached, the heat pump stops heang: the water temperature
is higher than or equal to the setpoint temperature.
• When the water ow rate is zero or is not enough, the heat pump stops: check that the water is
circulang correctly in the heat pump and that the hydraulic connecons are correct.
• The heat pump stops when the outdoor temperature falls below 5 °C for standard models or
-5 °C for “Defrost” models.
• It may be that the heat pump has detected an operang fault (see § “5.2 I Error code display”).
• If you have checked these points and the problem persists: contact your reseller.
The device is
draining water
• Oen called condensaon, this water is the moisture contained in the air which condenses
on contact with certain cold mechanisms in the heat pump, especially on the evaporator. The
more damp the air, the more condensaon your heat pump will produce (your device may
drain several litres of water per day). This water is retrieved by the base of the heat pump and
drained through a hole.
• To check that the water is not coming from a leak in the pool circuit on the heat pump, shut
down the heat pump, wait a few minutes and run the ltraon pump for the water to circulate
in the heat pump. If the water connues to ow through the condensaon drain, there is a
water leak in the heat pump; contact your reseller.
The evaporator is
iced over
• Your heat pump will soon switch to its defrost cycle to melt the ice.
• If your heat pump cannot manage to deice its evaporator, it will stop itself; this means that the
outdoor temperature is too low (below 5 °C for standard models, -5 °C for “Defrost” models).
The device is not
working
• If there is no display, check the supply voltage and the F1 fuse.
• When the setpoint temperature is reached, the heat pump stops heang: the water temperature
is higher than or equal to the setpoint temperature.
• When the water ow rate is zero or is not enough, the heat pump stops: check that the water
is circulang correctly in the heat pump.
• The heat pump stops when the outdoor temperature falls below 5 °C for standard models or
-5 °C for “Defrost” models.
• It may be that the heat pump has detected an operang fault (see § “5.2 I Error code display”).
The device is
working but
the water
temperature does
not increase
• It may be that the heat pump has detected an operang fault (see § “5.2 I Error code display”).
• Check that the automac lling valve is not stuck in open posion; this will keep supplying cold
water into the pool and will prevent the temperature from rising.
• There is too much heat loss as the air is cool. Install a heat insulated cover on your pool.
• The heat pump is unable to capture enough calories as its evaporator is clogged with dirt. Clean
it to restore its performances (see § “4.2 I Maintenance”).
• Check that the external environment is not hindering the heat pump (see § “❷ Installaon”).
• Check that the heat pump is the right size for this pool and its environment.
The venlator is
running but the
compressor stops
from me to me
with no error
message
• If the outdoor temperature is low, the heat pump will perform defrost cycles.
• The heat pump is unable to capture enough calories as its evaporator is clogged with dirt. Clean
it to restore its performances (see § “4.2 I Maintenance”).
The device trips
the circuit breaker
• Check that the circuit breaker is correctly dimensioned and that the cable secon used is
the right one (see § “1.2 I Technical specicaons”).
• The supply voltage is too low; contact your electricity supplier.
