HYDRAULIC CONNECTIONS
- Carry out the hydraulic connections.
WARNING: Always use a spanner with
counter-spanner to connect the
piping.
The positions, type and diameters of the
hydraulic connections are shown in the
dimensional data.
It is recommended to properly insulate
the water piping to avoid condensate
drips during cooling operation.
After the installation verify the tightness
of the connections.
Warning: Vent the hydraulic system.
The air vents are located on the upper
part of the coil close to the hydraulic
connections.
Warning: To drain the unit use the drain
valves located on the lower part of the
coil close to the hydraulic connections.
CONDENSATE DISCHARGE CONNECTION
The fan coil unit drain pan has 2 outlets
on each side; one for vertical and one for
horizontal installation.
It is recommended to use the condensate
drain connection on the side of the
hydraulic connections.
For horizontal installations mount the
condensate discharge drain connection
provided loose. Care should be taken to
seal the fitting between the drain pan
and the drain connection with silicone
sealant.
Seal the drain not used.
Connect the drain pan fitting to the
condensate drain system. Use a drain
tube that must be connected to the
condensate discharge fitting. The
condensate drains are designed to be
connected only by flexible tubes of
adequate internal diameter, avoid

imposing additional load and do not use
them for any other purposes.
Ensure that the drain not used is sealed
and has no leaks.
The condensate drain system must be
appropriately sized and the piping
positioned in such a way to maintain a
slope (min. 1%).
To avoid unpleasant smells a trap is
recommended if the condensate is
connected to the sewage system.
Carry out a functional and leak test of the
installation by pouring water into the
drain pan.
