Do NOT use excessive force when connecting the piping. Deformation of the piping
can cause malfunctioning of the unit.

valve are provided. Mount the shut-off valves on the space heating water inlet and
space heating water outlet. To ensure the minimum flow rate (and prevent
overpressure), install the overpressure bypass valve on the space heating water
outlet.
