3.6. Air for the heat pump supplied from and discharged outside

Make sure that there is proper distance between suction duct and cold air outlet.

3.7. Hydraulic connection

Connecting heater to a heat pump should be handled by a qualified person.
Heater should be directly connected to water supply network (with a
possibility to disconnect it through a shut-off valve) with pressure not
exceeding 1,0 MPa, while minimum pressure can't be lower than 0,1 MPa.
If the water pressure inside water supply network exceeds 1,0 MPa, it is
required to reduce the pressure by using the reducing valve. Safety valve
should be installed on the pipe through which cold water is flowing. Safety
valve's discharge hole has to remain open - connected with the atmosphere.
During installation we recommend using expansion vessel which protects
from hydraulic shocks.
Connecting additional source to the water heater through coil requires a
shut-off valve that allows disconnecting the and check valves which stop
heat from escaping the , if it is not heated by an outside heat source. When
connecting DHW circulation installation it is required to have a shut-off
valve and a check valve. Power pipe for DHW is also required to have a shut-
off valve. All connection pipes are required to have insulation.
To empty the it is required to use the drain valve installed by following the
diagram.
