• Do not stand on or lean on unit.
• Do not place objects on top or below the unit and observe service space requirements when placing objects next to the unit.
• Do not touch the unit or controller with wet hands as electric shock may result.
• Do not remove the panels of the unit or try to force objects inside the unit's casing.
• Do not touch protruding pipework as it may be very hot and cause burns to the body.
• Should the unit start vibrating or making abnormal noises stop operation, isolate from the power supply and contact the installer.
• Should the unit start to produce any burning smells stop operation, isolate from the power supply and contact the installer.
• Should water be visibly being discharged through the tundish stop operation, isolate from the power supply and contact the installer.
• This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
• Children should be supervised to ensure that they do not play with the appliance.
• In the case of a refrigeration leak, stop the operation of the unit, thoroughly ventilate the room and contact the installer.
• If power supply cable is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
• Do not place containers with liquids on top of the unit. If they leak or spill the unit may be damaged and fire could occur.
• When installing, relocating, or servicing the cylinder unit and the hydrobox, use only the heat pump's specified refrigerant to charge the refrigerant
lines. Do not mix it with any other refrigerant and do not allow air to remain in the lines. If air is mixed with the refrigerant, then it can be the cause of ab-
normal high pressure in the refrigerant line, and may result in an explosion and other hazards.
The use of any refrigerant other than that specified for the system will cause mechanical failure or system malfunction or unit breakdown. In the worst
case, this could lead to a serious impediment to securing product safety.
• In heating mode, to avoid the heat emitters being damaged by excessively hot water, set the target flow temperature to a minimum of 2ºC below the
maximum allowable temperature of all the heat emitters. For Zone2, set the target flow temperature to a minimum of 5ºC below the maximum allowable
flow temperature of all the heat emitters in Zone2 circuit.
• This appliance is primarily intended for domestic use. For commercial applications this appliance is intended to be used by expert or trained users in
shops, in light industry and on farms, or for commercial use by lay persons.
• Do not use means to accelerate the defrosting process or to clean, other than those recommended by the manufacturer.
• The appliance shall be stored in a room without continuously operating ignition sources (for example: open flames, an operating gas appliance or an
operating electric heater).
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odour.
• Do not use sharp objects to press the buttons of the main remote controller as this will cause damage to the buttons.
• If power to unit is to be turned off for a long time, the water should be drained.
• Do not place a container etc. filled with water on the top panel.
This mark is for R32 refrigerant only. Refrigerant type is written on nameplate of outdoor unit.
In case that refrigerant type is R32, this unit uses a flammable refrigerant.
If refrigerant leaks and comes in contact with fire or heating part, it will create harmful gas and there is risk of fire.
