Connection to the hydraulic installation
The HPM heat pump can operate in a closed hydraulic installation system (minimum
pressure of the heating medium is 0.6 bar).
Hydraulic installation should be made in accordance with applicable standards. Wires
connecting the heat pump to the indoor module should have an inside diameter of min.
25mm. In order to protect against the transmission of vibrations to the system, flexible
hoses must be used to connect the heat pump. Attach the hose to condensate drain.
The heating medium pipes and the drain pipe should be thermally insulated. The outlet
of the drain hose should be placed below depth exposed to freezing.
In case of minus temperatures, do not switch off the device. This will protect the outdoor
unit condenser from damage. If there is a risk of interruptions in the supply of electricity,
the circuit must be separated from hydraulic module by means of an additional heat
exchanger and the heat pump's heating circuit should be filled with glycol.
A prerequisite for maintaining the warranty is the installation of a dirt separator fixed
at the inlet to the device.
The hydraulic installation must be made in such a way that the internal HPMI unit can
operate in the heating circuit without external HPMO unit (according to the following
installation diagrams). In case of a failure of the HPMO outdoor unit this will ensure the
functioning of the heating system.
