NOTICE
Do NOT use excessive force when connecting the piping. Deformation of the piping
can cause malfunctioning of the unit.
To facilitate service and maintenance, 2 shut-off valves and 1 overpressure bypass
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.
1 Install the shut-off valves on the space heating water pipes.
2 Screw the indoor unit nuts on the shut-off valve.
3 Connect the domestic hot water in and out pipes to the indoor unit.
