INSTALLATION OF THE HEAT PUMP
The heat pump must be placed in a room free from freezing. The appliance must be connected to the heating circuit of the building’s
central heating.
During operation, domestic water is heated using the energy from the central heating system. For optimal operation of the heat pump,
water temperature must be between 12 °C and 40 °C in the heating circuit. The user must ensure a sufficient flow rate of the heating
water – the source. Minimum flow rate of the source that is needed for the heat pump to operate is 120 l/h. A deaerator must be
placed on the highest point of the source inlets. Heat losses are greater in a room with cold air. To prevent condensation it is
recommended to insulate the pipes connected to the source.
If the temperature of the source is lower than 12 °C or higher than 40 °C, the electric heater will activate to heat the domestic water.
The electric heater will also activate if the flow rate of the source is lower than 120 l/h. The heat pump will operate in reserve mode.
To reduce the transfer of noise and vibrations through walls or the floor to rooms where this would be disturbing (bedrooms, rooms
intended for resting) please make sure to take the following measures:
- install flexible joints for hydraulic connections
- plan vibration insulation for wall openings
- use positioning feet (for floor-standing version)

EN
WALL-MOUNTED VERSION
When selecting the place of installation, pay attention to the solidity of the wall – can it take the weight of the heat pump together with
the weight of the water inside the water tank? Mount the heat pump in an upright position only, using wall screws with a nominal
diameter of min. 8 mm. A wall with poor bearing capacity must be properly reinforced at the place of installation. For easier inspection
and replacement of the magnesium anode, it is recommended to leave enough space between the appliance and the ground (Fig.
4a). Otherwise the appliance will have to be dismounted from the wall for service interventions.
Make sure to take measures to prevent the transfer of noise and vibrations through walls where this would be disturbing (bedrooms,
rooms intended for resting).
A radiator can be connected only to the TC…ZWR model.
Fig. 4a: Minimum requirements for the installation of HP
FLOOR-STANDING VERSION
Before setting up the appliance, screw in the enclosed adjustable feet. Level the heat pump longitudinally and laterally by rotating the
adjustable feet. Take into account the minimum permissible distance from the wall and the ceiling.
Make sure to take measures to prevent the transfer of noise and vibrations through walls where this would be disturbing (bedrooms,
rooms intended for resting).

EN
CONNECTION TO WATER SUPPLY MAINS
Inlet and outlet of sanitary water are color-coded on the heat pump pipes. The cold sanitary water inlet is marked blue and the hot
sanitary water inlet is marked red. You can connect the heat pump to the house water pipeline without a reducing valve if the pressure
in the network is lower than the nominal pressure (indicated on the data plate). If the pressure is higher, a relief valve needs to be
installed so as to provide that the pressure at the inlet to the hot water tank does not exceed the nominal pressure.
Installing a safety valve is mandatory in order to assure safe operation. The valve prevents an increase of the pressure in the boiler by
any more than 0.1 MPa (1 bar) above the rated pressure. The outflow nozzle on the safety valve must have an outlet into the
atmosphere. To assure correct operation of the safety valve, the valve must be regularly checked.
When checking the valve, push the lever or unscrew the nut of the valve (depending on the type of the valve) and open the drain from
the safety valve. Water must flow from the valve nozzle, showing that the valve operation is faultless. During the heating of water, the
water pressure in the hot water tank is increased up to the level preset in the safety valve. Since the system prevents backflow of
water into the water supply mains, water may be dripping from the outlet opening on the safety valve. The dripping water may be
drained via trap into the drains; the trap is mounted under the safety valve. The outlet pipe, which is mounted under the safety valve,
must be directed downwards, in a place with a temperature above freezing.
If the installation does not allow draining of the water from the safety valve into the drains, dripping can be avoided by installing an
expansion vessel onto the heat pump inlet pipe. The volume of the expansion vessel must be ca. 3% of the hot water tank volume.
After connecting the heat pump to the water mains, the water tank must be filled with water.
Fig. 5: Closed (pressure) system
CONNECTION TO THE CENTRAL HEATING SYSTEM
Connection to the heating system is on the back side of the heat pump (wall-mounted version) or on the left side of the heat pump
(floor-standing version). The heating source water inlet is marked with IN and the heating source water outlet is marked with OUT.
You may only connect the heat pump to the central heating system if the minimum flow rate of heating source water of 120 l/h is
provided. The heating source water temperature must be kept in the range between 12 °C and 40 °C, otherwise the heat pump will
operate in reserve mode.
To the top point of heating source water connections, the air valve must be installed (Fig. 4a, Fig. 4b). The heating system to which
the sanitary heat pump is connected must have a built-in expansion vessel and a safety valve! The system must not contain glycol!
Fig. 6: Connection to the central heating system
Before filling the system, it must be cleaned of all impurities and an impurity filter must be installed.

"RADIATOR HEATING" FEATURE (APPLIES TO TC...ZWR MODELS)
The feature controls the heating of a radiator connected to the heat pump. You can choose between manual activation, automatic
operation, timer operation or external control of the “radiator heating” feature. If the symbol in field 11 is not visible, the “RADIATOR
HEATING” feature is not available.
a) MANUAL ACTIVATION OF THE “RADIATOR HEATING” FEATURE
In this feature you can set the time of radiator heating.
