works.
This heat pump contains a flammable refrigerant R32.
Any intervention on the refrigerant circuit is prohibited without a valid autho-
rization.
Before working on the refrigerant circuit, the following precautions are neces-
sary for safe work.
1. Work procedure
The work must be carried out according to a controlled procedure, in order to mini-
mize the risk of presence of flammable gases or vapors during the execution of the
2. General work area
All persons in the area must be informed of the nature of the work in progress. Avoid working in a confined
area. The area around the work area should be divided, secured and special attention should be paid to
nearby sources of flame or heat.
3. Verification of the presence of refrigerant
The area should be checked with a suitable refrigerant detector before and during work to ensure that
there is no potentially flammable gas. Make sure that the leak detection equipment used is suitable for
flammable refrigerants, ie it does not produce sparks, is properly sealed or has internalsafety.
4. Presence of fire extinguisher
If hot work is to be performed on the refrigeration equipment or any associated part, appropriate fire extin-
guishing equipment must be available. Install a dry powder or CO2 fire extinguisher near the work area.
5. No source of flame, heat or spark
It is totally forbidden to use a source of heat, flame or spark in the direct vicinity of one or more parts or
pipes containing or having contained a flammable refrigerant. All sources of ignition, including smoking,
must be sufficiently far from the place of installation, repair, removal and disposal, during which time a
flammable refrigerant may be released into the surrounding area. Before starting work, the environment
of the equipment should be checked to ensure that there is no risk of flammability. «No smoking» signs
must be posted.
6. Ventilated area
Make sure the area is in the open air or is properly ventilated before working on the system orperforming
hot work. Some ventilation must be maintained during the duration of the work.
7. Controls of refrigeration equipment
When electrical components are replaced, they must be suitable for the intended purpose and the appro-
priate specifications. Only the parts of the manufacturer can be used. If in doubt, consult the technical
service of the manufacturer.
The following controls should be applied to installations using flammable refrigerants:
- The size of the load is in accordance with the size of the room in which the rooms containing the
refrigerant are installed;
- Ventilation and air vents work properly and are not obstructed;
- If an indirect refrigeration circuit is used, the secondary circuit must also be checked.
- The marking on the equipment remains visible and legible. Illegible marks and signs must be corrected;
- Refrigeration pipes or components are installed in a position where they are unlikely to be exposed to a
substance that could corrode components containing refrigerant
8. Verification of electrical appliances
Repair and maintenance of electrical components must include initial safety checks and component
inspection procedures. If there is a defect that could compromise safety, no power supply should be
connected to the circuit until the problem is resolved.
Initial security checks must include:
•That the capacitors are discharged: this must be done in a safe way to avoid the possibility of sparks;
•No electrical components or wiring are exposed during loading, recovery or purging of the refrigerant
gas system;
•There is continuity of grounding.

All equipment, even if shipped ‘free of carriage and packing’, is dispatched at the consignee’s own
risk.
The person responsible for receiving the equipment must carry out a visual inspection to identify
any damage to the heat pump during transport (refrigerant system, body panels, electrical control
box, frame). He/she must note down on the carrier’s delivery note any remarks concerning
damage caused during transport and confirm them to the carrier by registered letter within 48
hours.
The equipment must always be stored and transported vertically on a pallet and in its original
packaging. If it is stored or transported horizontally, wait at least 24 hours before switching it on.
During installation and servicing
Only a qualified person may undertake installation, start-up, servicing and repairs, in compliance
with current standards.
Before operating or undertaking any work on the equipment (installation, commissioning, usage,
servicing), the person responsible must be aware of all the instructions in the heat pump’s
installation manual as well as the technical specifications
Under no circumstances install the equipment close to a source of heat, combustible materials or
a building’s air intake.
If installation is not in a location with restricted access, a heat pump protective grille must be fitted
Toavoid severe burns, do not walk on pipework during installation, repairs or maintenance.
Toavoid severe burns, prior to any work on the refrigerant system, turn off the heat pump and wait
several minutes before placing temperature and pressure sensors.
Check the refrigerant level when servicing the heat pump.
Check that the high and low pressure switches are correctly connected to the refrigerant system
and that they turn off the electrical circuit if tripped during the equipment’s annual leakage
inspection.
Check that there is no trace of corrosion or oil stains around the refrigerant components.
WARNING : Please read carefully the safety instructions before using the equipment.
The following instructions are essential for safety so please strictly comply with
them.

During use
Toavoid serious injuries, never touch the fan when it isoperating.
Keep the heat pump out of the reach of children to avoid serious injuries caused by the heat
exchanger’s blades.
Never start the equipment if there is no water in the pool or if the circulating pump is stopped.
Check the water flow rate every month and clean the filter ifnecessary.
During cleaning
Switch off the equipment’s electricity supply.
Close the water inlet and outletvalves.
Do not insert anything into the air or water intakes or outlets.
Do not rinse the equipment with water
Rinse onlythe titanium with water
During repairs
Carry out work on the refrigerant system in accordance with current safetyregulations.
Brazing should be performed by a qualified welder.
When replacing a defective refrigerant component, use only parts certified by our technical
department.
When replacing pipework, only copper pipes conforming to Standard NF EN12735-1 may beused
for repairs.
When pressure-testing to detectleaks:
Toavoid the risks of fire or explosion, never use oxygen or dry air.
Use dehydrated nitrogen or a mixture of nitrogen andrefrigerant.
The low and high side test pressure must not exceed 42bar.
heat pumps for swimming pools can be used with all types of water treatmentsystems.
Nevertheless, it is essential that the treatment system (chlorine, pH, bromine and/or salt chlorina-
tor metering pumps) is installed after the heat pump in the hydraulic circuit.
To avoid any deterioration to the heat pump, the water’s pH must be maintained between
6.9 and 8.0.

The heat pump should be located at least 2.5 meter away from the swimming pool.
Please comply with the following rules concerning the choice of heat pump location.
1. The unit’s future location must be easily accessible for convenient operation and maintenance.
2. It must be installed on the ground, laid ideally on a level concrete base . Ensure that the floor
is sufficiently stable and can support the weight of the unit
3. Check that the unit is properly ventilated, that the air outlet is not facing the windows of neigh-
boring buildings and that the exhaust air cannot return. In addition, provide sufficient space
around the unit for servicing and maintenance operations.
4. The unit must not be installed in an area exposed to oil, flammable gases, corrosiveproducts,
sulfurous compounds or close to high frequency equipment.
5. Toprevent mud splashes, do not install the unit near a road or track.
6. Toavoid causing nuisance to neighbors, make sure the unit is installed so that it is positioned
towards the area that is least sensitive to noise.
7. Keep the unit as much as possible out of the reach of children.
