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.
Always transport the outdoor unit of the heat pump in an upright position; exceptionally, it
may be tilted by 35° in all directions. Be careful not to damage the housing or the vital
component parts of the appliance during transport.
The heat pump must not be placed in a closed space, containing corrosive and explosive
materials.
The connection of the heat pump to the power supply must be performed in accordance
with the standards for electrical installations. An appliance for the disconnection from the
electrical network must be installed between the heat pump and the electrical network in
accordance with the national installation regulations.
In avoidance of aggregate damage the heat pump must not operate without 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.
It is necessary to install a safety valve with a rated pressure of 0.6 MPa (6 bar) or 0.9 MPa
(9 bar) (see nameplate), to prevent the pressure in the boiler from rising by more than 0.1 MPa
(1 bar) above the rated pressure.
Water may drip from the outlet opening of the safety valve, 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 stop valve between the heat pump and the safety valve, because it will
impair the pressure protection of the storage tank!
Elements of the electronic control unit are under voltage even after the heat pump has
been switched off (9).
To avoid danger, a damaged connecting line and connecting cable for connecting the
indoor and outdoor units can only be replaced by the manufacturer, its service provider or an
authorised person.
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 heat pump 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
