NOTICE
Applicable legislation on fluorinated greenhouse gases requires that the refrigerant
charge of the unit is indicated both in weight and CO
Formula to calculate the quantity in CO
refrigerant × total refrigerant charge [in kg] / 1000
Use the GWP value mentioned on the refrigerant charge label. That GWP is based on
the current legislation on fluorinated greenhouse gases. The GWP mentioned in the
manual might be outdated.
2 Fix the label on the inside of the outdoor unit near the gas and liquid stop
valves.
Before connecting the water piping
Make sure the outdoor and indoor unit are mounted.

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.
