WATER CONNECTION
To achieve maximum heat exchanger efficiency, always
note and follow the manufacturer's data on the side of
the fan coil (flow / return on the heat exchanger).
Mixing up the water connections would not impair op-
eration, but reduces the heat exchanger efficiency.
The water connections (½" internal thread) are welded
directly onto the coil. The recesses on the sides of the in-
ternal structure are designed to ensure that it is not pos-
sible for the connections to twist. To prevent damage
(e.g. twisting off the connections on the heat exchang-
er), it is important to screw in the supply pipes carefully.
To prevent unnecessary energy losses due to circulation
in standby, the flow rate at the fan coil is interrupted by
a 2 point valve, similar to underfloor heating. As soon as
there is a need for heating or cooling, the valve opens
and re-releases the flow.
More information on this is given in the System Accesso-
ries section of this operating manual.
NOTE.
The installation package available as accessories
is required for the hydraulic connection to the
heating and/or cooling system.
