INSTALLATION OF THE HOT WATER STORAGE
TANK WITH THE HEAT PUMP
The heat pump can be used using the ambient air or air from other premises.
To prevent pressure depression in the building, fresh air must be regularly supplied to the premises. The desired rate of air
exchange for a residential building is 0.5. This means that the entire quantity of air in the building is exchanged every two hours.
OPERATION USING AMBIENT AIR
In this type of operation, the device heats domestic water using only the amount of energy generated by the air from the room
where the device is installed. The heat pump must be installed in a dry, frost-free room, possibly in the vicinity of other heating
sources with the recomended temperature ranging between 7 and 35°C and a minimum volume of 20 m
For optimal performance of the heat pump, we recommend a sufficiently large and well ventilated room with the temperature
ranging between 15 °C and 25 °C.
When selecting a place for installation, particular attention should be paid that the selected air intake location is dust free, because
dust has adverse effects on the heat pump performance. Because pressure drop does not occur with the ambient air operation it is
reasonable to reduce the fan speed from factory settings of 60% to 40% to reduce noise (See further chapters).
There are several inlet and outlet openings possible with this model (See figure).
Elbows are more suitable for ambient air operation and must be installed on the heat pump and turned so that they
prevent the mixing of air.

OPERATION USING AIR FROM OTHER PREMISES
In this type of operation, the heat pump uses air from other premises via a pipeline system. It is advisable to insulate the pipeline
system to prevent the formation of condensate. In case of using air from outside, the external part must be covered so as to
prevent the intrusion of dust or snow into the appliance.
To make sure the operation of the pump is effective at all times, you can install dampers to take air from the premises and then
return it either to the premises or outside. The temperature of the taken air must correspond with the standards of the specification
of the product (see table with technical characteristics).
