INSTALLATION OF THE HOT WATER TANK AND HEATING PUMP
The hot water tank with heating pump can be used using the ambient air or air from
other premises.
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 hot water tank with heating pump can be
installed in in a dry room where it is not freezing,
possibly in the vicinity of other sources of heating,
with the temperature ranging from 7 to 35 °C and no
larger than 20 m

. Generally, we suggest a large
enough and well-ventilated room with the
temperature ranging between 15 and 25 °C, which
represents optimal conditions for the operation of the
heating pump. When selecting the room for installing
the hot water tank and heating pump, one should
make certain that the selected room is not too
exposed to dust, because dust has adverse effects on the efficiency of heating
pumps.
Before the beginning of the operation two 90° elbows must be installed to
the top of the appliance (ø150 mm), each facing in the opposite direction. The
premises must be properly ventilated.
Operation using air from other premises
In this type of operation, the heating pump brings air in and out of other premises
through a system of pipes. The pipes must be properly insulated to avoid
condensation inside the pipes. 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 the operation of the heating pump efficient at all times, you can install flow-
directing flaps to take in air from the premises or from outside and then return it when
necessary. The temperature of the air should always be above 7 °C.
