Water pipe-work
Checking the water circuit
The 3-way valve is built-in the unit. So the unit is equipped with the water inlet/outlet for hot water
connection, and the water inlet/outlet for space heating/cooling. The water circuits must be provided by
a licensed technician and must comply with all relevant European and national regulations.
THE UNIT IS ONLY TO BE USED IN A CLOSED WATER SYSTEM. APPLICATION IN AN OPEN WATER
CIRCUIT CAN LEAD TO EXCESSIVE CORROSION OF THE WATER PIPING.
Before
continuing
the
installation
of
the
unit,
check
the
following
points:
•
The maximum water pressure is 6 bar.
•
Four shut-off valves are not delivered with the unit. To facilitate service and maintenance,
please install one at each water inlet/outlet. Mind position of the shut-off valves. Orientation of
the integrated drain and fill valves is important for servicing.
•
Drain taps must be provided at all low points of the system to permit complete drainage of the
circuit during maintenance.
•
Make sure to provide a proper drain for the pressure relief valve to avoid any water coming into
contact with electrical parts.
•
Air vents must be provided at all high points of the system. The vents should be located at
points which are easily accessible for servicing. An automatic air purge is provided inside the
indoor unit. Check that this air purge valve is not tightened too much so that automatic release
of air in the water circuit remains possible.
•
Take care that the components installed in the field piping can withstand the water pressure.
