7.10.3 Connecting the water piping of the indoor unit
To connect the water piping for space heating
NOTICE
In case of old heating installations, it is recommended to use a dirt separator. Dirt or
sediment from the heating installation can damage the unit and reduce its lifetime.
NOTICE
Do NOT use excessive force when connecting the piping. Deformation of the piping
can cause malfunctioning of the unit.
NOTICE
▪
It is recommended to install shut-off valves to space heating in and space heating
out connections. Shut-off valves are field supplied. They allow service to the unit
without draining the whole system.
▪
Foresee a drain/fill point to drain or fill the space heating circuit
NOTICE
Do NOT install valves to shut down the entire emitter system (radiators, floor heating
loops, fan coil units, ...) instantly if this can result in an immediate short circuit of the
water flow between the outlet and the inlet of the unit (for example via a bypass
valve). This may trigger an error.
