WARNINGS
The appliance may be used by children aged 8 and older and persons with physical, sensory or
mental disabilities or lacking experience or knowledge, if they are under supervision or taught about
safe use of the appliance and if they are aware of the potential dangers.
Children should not play with the appliance.
Children should not clean or maintain the appliance without supervision.
During transport, the appliance must be placed in the upright position. In exceptional cases, it may be
inclined by up to 35° in all directions. Make sure the housing or vital parts of the product are not
damaged during transport.
The appliance must not be placed in a closed space containing corrosive and explosive materials.
The connection of the appliance to the power supply must be performed in accordance with the
standards for electrical installations.
A device for the disconnection from the electrical network must be installed between the appliance
and the electrical network in accordance with the national installation regulations.
In order to avoid damage to the heat pump power unit, never operate the appliance without any water
in the tank!
The installation should be performed in accordance with the valid regulations and the instructions of
the manufacturer. It should be performed by a professionally trained installation expert.
In case of a closed pressurized system, it is obligatory to install a safety valve with a rated pressure of
0.6 MPa (6 bar) on the inlet pipe of the hot water storage tank to prevent the elevation of pressure in
the tank by more than 0.1 MPa (1 bar) above the rated pressure.
Water may drip from the outlet opening of the safety valve. Therefore, so the outlet opening should be
set to atmospheric pressure.
The outlet of the safety valve should be installed facing downwards and in a non
-
freezing area.
To ensure proper functioning of the safety valve, the user should perform regular controls to remove
limescale and make sure the safety valve is not blocked.
Do not install a shut
-
off valve between the water tank and the safety valve, as this would disable the
operation of the safety valve!
Elements in the electronic control unit are energised even after you press the appliance off key.
The storage tank is protected in case of failure of the operating thermostat with an additional thermal
cut
-
out. In case of thermostat failure, water in the storage tank may reach the temperature of up to
130
°C in accordance with safety standards. The possibility of such temperature overload should be
taken into consideration in the execution of plumbing.
Should you choose to disconnect the power, the storage tank should be drained thoroughly before the
onset of freezing conditions.
Water from the storage tank is drained through the inlet pipe of the tank. For this purpose, a special
fitting (T
-
fitting) with an outlet valve must be mounted between the safety valve and the inlet pipe.
Please, do not try to fix any defects of the appliance on your own. Call the nearest authorised service
provider.
The decline in temperature of an additional heating source and the enabled water circulation via the
heat exchanger can cause an uncontrolled removal of heat from the water tank. When connecting to
other heating sources it is necessary to ensure proper temperature regulation of the additional heating
source.
When connecting to sources of solar energy as an external heating source the aggregate of the heat
pump must be disconnected. The combination of both heating systems can lead to overheating of
water and consequently to excessive pressure.
Circulation leads to additional heat loss in the water tank.
In models without a heater, the hot water storage tank is not protected from freezing!
This appliance contains fluorinated greenhouse gases. Hermetically sealed.
