❸ Maintenance
3.1 I Winterising
• Even though the appliance can be used year round, if it will not be used for the winter months,
a suitable winterising procedure must be implemented to prevent damage to the condenser.
Damage caused by improper winterising of the appliance when not in use is not covered by
the warranty.
• To prevent condensaon from damaging the appliance: cover the appliance with the
winterising cover supplied (do not hermecally-seal the appliance inside a cover).
• Set the regulator to "standby" mode by pressing and disconnect the power supply,
• Open valve B (see § "1.2 I Hydraulic connecons"),
• Close valves A and C and open valves D and E (if present, see § "1.2 I Hydraulic connecons"),
• Make sure that there is no water circulang in the heat pump,
• Drain the water from the condenser (risk of freezing) by unscrewing the two water inlet and outlet connectors on the
back of the heat pump,
• In the case of full winterising for the pool (complete shutdown of the ltraon system, bleed the ltraon circuit
or even pool drainage): re-t the two connectors by one turn to prevent any foreign bodies from geng into the
condenser,
• In the case of winterising the heat pump only (shutdown of the heang only, the ltraon keeps running): do not re-t
the connectors; instead add 2 caps (not provided) on the condenser's water inlet and outlet.
• We recommend that you put the aired winterising micro cover (provided) over the heat pump.
3.2 I Maintenance
• Before any maintenance work on the appliance, you must cut the electricity supply as there is
a risk of electric shock which may cause material damage, serious injury or even death.
• It is recommended that the appliance undergo general servicing at least on a yearly basis to
ensure its proper operaon, maintain performance levels and prevent any possible failures.
These operaons are carried out at the user's expense, by a qualied technician.
3.2.1 Safety instrucons concerning 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
2
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.
