4.4 Connecting the water piping
4.4.1 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.
1 Connect the water inlet connection (Ø22 mm).
2 Connect the water outlet connection (Ø22 mm).

3 In case of connection with the optional domestic hot water tank,
see the installation manual of the domestic hot water tank.
NOTICE
Install air purge valves at all local high points.
4.4.2 To fill the space heating circuit
Before filling the space heating circuit, the gas boiler MUST be
installed.
1 Flush the installation thoroughly to clean the circuit.
2 Connect the water supply hose to the drain point (field supply).
3 Power up the gas boiler to see the pressure indication on the
boiler display.
4 Make sure that the air purge valves of the gas boiler and the
heat pump module are open (at least 2 turns).
5 Fill the circuit with water until the boiler display indicates a
pressure of ±2 bar (with a minimum of 0.5 bar).
6 Purge air from the water circuit as much as possible.
