Circulating pumps
Circulating pumps shall ensure required water flow.
Domestic hot water
If domestic hot water is to be provided by heat pump, it required to ensure additional circuit, in parallel to
heating circuit. At the phase of design and installation note that water is not supplied through central
heating circulation buffer.
Domestic hot water storage tank
If heat pump is to be used to deliver domestic hot water, specially designed domestic hot water
storage tanks shall be provided, adapted for operation along with heat pump. Capacity of such
domestic hot water storage tank shall be appropriate to ensure hot water supply also when power
failure follows. Heat exchange surface shall be appropriate to ensure transfer of heat pump output at the
smallest differential temperature. Also a tank having min. 200L capacity shall be provided for toilet and
bath purposes.
The minimum heating surface of the coil is 1.8 m
2
Filters
Any system including heat pump shall be provided with filters to protect heat exchanger
against contamination. Filters shall be installed before the top pump.
Floor slab
Optionally the external unit may be installed next to the wall or within free spaces. Heat pump
position shall ensure protection against exposure to wind, however if it is not possible it is
recommended to install heat pump perpendicularly to prevalent wind direction. Devices shall be
placed on load-bearing, strong and horizontal base appropriate to device mass. Device foundation shall
not be connected with building. Always check that foundation provided is appropriate to heat pump
weight. When delivering wall penetration always ensure distance from wall, as required.
Read carefully controller operation manual
Condensate drain
Note to ensure safe condensate drain. Product contains R290 refrigerant. In case of leakage
refrigerant penetration into soil may follow through condensate drain. Always prevent refrigerant
discharge into sewers. In case of device installed to the ground, note to ensure condensate drain with
discharge pipe to gravel subbase provided within area protected against freezing.
WARNING! Freezing causes damages! Refrigerant freezing prevents its discharge from heat
pump and poses risk of evaporator damage.
