3.1 I Winterizing
• Although the device may be used year around, in the event that it will not be used during the
winter months, proper winterizing is necessary in order to prevent damage to the condenser.
Damage due to failure to properly winterize the unit when it is not use is not covered by the
warranty.
• To prevent condensation from damaging the appliance: cover the appliance with the
winterising cover supplied (do not hermetically-seal the appliance inside a cover).
• Set the regulator to "standby" mode by pressing and holding
• Open valve B,
• Close valves A and C and open valves D and E (if present),
• Make sure that there is no water circulating 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 winterizing for the pool (complete shutdown of the filtration system, bleed the filtration circuit
or even pool drainage): tighten the two connectors by one turn to prevent any foreign bodies from getting into the
condenser,
• In the case of winterizing for the heat pump only (shutdown of the heating only, the filtration keeps running): to not
tighten the connectors but add 2 caps (provided) on the condenser's water inlets and outlets.
• We recommend that you put the aired winterizing micro cover (provided) on the heat pump.
3.2 I Maintenance
• Before performing any maintenance operation 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 proper operation, maintain performance levels and potentially prevent certain
failures. These operations are carried out at the user's expense by a qualified technician.
3.2.1 Safety instructions concerning appliances containing R32 refrigerant (Z400iQ MD4, MD5, TD7, TD8,
TD9 models)
Area check
• Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to ensure that the
risk of ignition is minimised.
Work procedure
• Work shall be undertaken under a controlled procedure so as to minimise the risk of a flammable gas or vapour being
present while the work is being performed.
General work area
• AIl maintenance staff and others working in the local area shall be instructed on the nature of work being carried out.
Work in confined spaces shall be avoided.
Check for the presence of refrigerant
• The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician
is aware of potentially toxic or flammable atmospheres. Ensure that the leak detection equipment being used is
suitable for use with all applicable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.
Check for the presence of a fire extinguisher
• If any work involving heat is to be conducted on the refrigerating equipment or any associated parts, appropriate
fire extinguishing equipment shall be available to hand. Have a dry powder or CO
charging area.
No source of ignition
• No person carrying out work in relation to a refrigerating system which involves exposing any pipe work shall use
any sources of ignition in such a manner that it may lead to the risk of fire or explosion. All possible ignition sources,
including cigarette smoking, should be kept sufficiently far away from the site of installation, repairing, removing and
disposal, during which refrigerant can possibly be released to the surrounding space. Prior to work taking place, the
area around the equipment is to be surveyed to make sure that there are no flammable hazards or ignition risks. «No
Smoking» signs shall be displayed.
