4PURPOSE OF THE DEVICE
The device is an air/water heat pump with a UniQube water storage tank below. Its primary task is to heat sanitary
water –the cooling effect on the surroundings is a side effect. The heat pump needs to be set in a sufficiently large and
ventilated room with an enough high air temperature (basement, pantry) from which it will take the energy for its
operation. The heat pump draws 75% of the necessary heat from the air, the rest is provided by the electrical power
that drives the high-quality rotary compressor. The sanitary water is heated through a refrigerant heat exchanger
(condenser) submerged in the water of the storage tank. It is 310L hot water tank. The 310L tank unit is meant to be
installed in a building with a daily consumption not more than 700L per day.
WARNING!
Injuries and resulting damage to the device or third things, which are caused due to misuse and improper use
of the device, are the users sole responsibility.

6 REFRIGERANT
The unit is prefilled with HFC R134a refrigerant. The refrigerant is non-toxic, non-flammable and not explosive, is also
not harmful to the ozone layer, but is heavier than air, which can lead to a crowding-out of air from the area. The result
may be smaller concentration of oxygen in the air, but because of a very small amount of refrigerant in the unit, there
are no serious health risks. A reduced concentration of oxygen can occur only in unventilated areas less than 10 m3
volume. Nevertheless, we recommend that you read the manufacturer's refrigerant safety sheet and handle in
accordance with the written instructions.

11 UNIT INSTALLATION
Minimal space requirements for installation and maintenance
The unit must always be installed in a vertical position. We recommend that the unit is inclined 2-3° backwards to
enable smoother condensate runoff.
WARNING!
After placing the unit in its final location, wait at least 1 hour before turning the unit on.
WARNING!
In case of service intervention and if minimum clearances are disregarded, the user covers the costs
incurred.
Min. one elbow is required. Because the inlet and outlet air connections are very close together, there is a possibility of
cold air recirculation, the device will go to defrost mode more often.
WARNING!
Good insulation of neighbouring walls is advisable.
Installation possibilities:
WARNING!
Maximal length of air ducts is 10m. Each bend 90°reduces the maximal length for 1 m. All air duct pipes need
to be insulated to prevent condensation. Never reduce the internal diameter of the pipe.
When the air inlet and outlet are in a
different space, each space needs to have
an opening to the outside or they need to
be connected with an opening surface at
least 300mm2 to be able to equalize
pressure.

12 WATER CONNECTION
The cold water connection must be performed according to the scheme above. The maximum allowed pressure in the
hygienic domestic water system is 1,0 MPa, a safety valve sould be choosen by installer. Expansion vessel for the
hygienic domestic water circuit is optional, and is not mandatory necessary.
Hot water connection can be directly to tap, or can be upgraded with a circulation pump. Return from the circulation
system can be connected to the connection marked with “A”in scheme “10 Unit dimensions”.
During rapid water heating, a small water leakage on the safety valve can occur. This is not due to damage but due to
normal event of water expansion. This water needs to be captured and lead into drainage.
In case of a solar system or other heat source connected to the internal heat exchanger, it must be assured that the
pressure in the heat exchanger never exceeds 1,0 MPa. It must also be assured that the water does not exceed 80°C.
Damage to internal components or heat pump can occur.
In case that the additional heat exchanger is not to be used, it needs to be filled with glycol to prevent corrosion. It is
not allowed to close both sides of the heat exchanger to enable pressure equalization.
WARNING!
Improper installation of the unit can lead to damages or malfunction of the unit and loss of rights under
warranty.
WARNING!
Connect the unit to the system using removable pipe unions, so that the unit can be easily moved or removed
in case of a service intervention without the need of a greater intervention in the piping system.
WARNING!
When connecting the unit to the heating system it is necessary to prevent the formation of a galvanic couple
and related corrosion. To connect the unit to the heating system it is MANDATORY to use the enclosed
transition pieces, also the piping system MUST be electrically grounded. In case of failure due to improper
device connection the manufacturer will take no liability or warranty.
WARNING!
Before the unit is turned on, it needs to be filled with water and the system completely vented. To do this,
open all hot water taps and wait until water starts to flow from all of them.
WARNING!
On the back side of the unit there is a pipe connection for condensate drain. At high water usage and high air
humidity, more than a few litres of condensate water per day can occur, so this connection must be
connected to outlet drainage. This pipe needs to have a constant incline of at least 1° and must be always
clean.
5/4”
