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.
TROUBLESHOOTING
• All soldering work must be carried out by a someone qualied to do so.
• Replacement pipes must always be made of copper in compliance with standard
NF EN 12735-1.
• Leak detecon, pressure test:
- never use oxygen or dry air (risk of re or explosion)
- use dry nitrogen or the mixture of nitrogen and coolant indicated on the
informaon plate,
- the test pressure for both the high and low pressure circuits must not exceed 42
bar (for R410A), 20 bar and 15 bar (for R407C) if the appliance is equipped with
the oponal pressure gauge.
• The high pressure circuit pipes are made of copper and have a diameter equal to or
greater than 1’’5/8. A cercate as indicated in §2.1 in compliance with standard NF
EN 10204 will be requested from the supplier and led with the facility's technical
documentaon.
• Technical data relave to the safety requirements of the various applicable direcves
are indicated on the informaon plate. All this informaon must be recorded in
the appliance's installaon manual, which must be kept in the its technical le:
model, code, serial number, maximum and minimum OT, OP, year of manufacture,
CE marking, manufacturer’s address, coolant and weight, electrical parameters,
thermo-dynamic and acousc performance.
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,

4
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.

Tip: reduce any noise annoyance from your heat pump
• Do not install it under or towards a window.
• Do not lt it towards your neighbours.
• Install it in an open space (sound waves are reected on surfaces).
• Install an acousc screen around the heat pump, respecng the distances (see diagram § «1.2 I Hydraulic
connecons»).
• Install 50 cm of exible PVC pipe at the heat pump water inlet and outlet to absorb vibraons.
• Increase the ltraon me by 50% and acvate "silence" mode. The heat pump will run for longer
with less power, but much more quietly and with an improved COP (energy savings). «Silence» mode is
parcularly well suited for maintaining the water temperature once the setpoint temperature has been
reached.
