the devices installed in the network (on/off valves...). Use a
material that is suitable for the operating conditions and wa-
ter temperature.
Ū Bleed air from the exchanger by means of the air vent valves
located next to the water connections of the coil. Depending
on the installation, it may be necessary to place other vent
valves on the hydraulic system.
Condensate drain connection
Connect a rigid PVC pipe to the end of the hose and secure it
with a clamp
Correctly insulate the pipe with polyethylene foam.
Ū Be careful of the risk of freezing in winter in suspended ceil-
ings.
Ū If necessary, the condensate pipe can be routed immediately
after the unit's outlet. Maximum height: 900 mm (FIGURE 1).
Ū Make sure that the drainpipe has a slight slope in the direc-
tion of flow and that it does not form a siphon (FIGURE 1).
Ū The piping must have several supports (FIGURE 2).
Ū Do not install an air vent (FIGURE 3) in the wrong position.

5.2 DIMENSIONAL UNIT ASSEMBLY
Ū Use the dimensional drawings to determine the position of
the suspension rods (Fig.4 FWH-A 02-03-04) (Fig.5 FWH-A 06-
07-08)
Ū Position the suspension rods (not supplied) in place.
Ū Attach the supplied brackets (Fig.6 ) to the suspension rods
(Fig.7 ). The length of the suspension rods depends on the
space between the suspended ceiling and the structural
ceiling.
Ū The distance C (Fig.7 ) must be:
Model
FWH-A 02-03-04
FWH-A 06-07-08
Ū Pay attention to the excess length B of the suspension rod
(Fig.7 ): it may interfere with the unit's electrical box.
Ū Place the fan coil unit in the suspended ceiling, orienting
the side with the water connections in the most appropriate
position, using the hooks on the brackets to provide quick
temporary installation.
Ū Then attach the unit to the threaded bars with the screws
provided and check that it is level (Fig.8 )
Ū Adjust the distance between the unit and suspended ceiling
D (Fig.9 FWH-A 02-03-04 and Fig.10 FWH-A 06-07-08) using
the nuts of the suspension rods:

Ū Make sure that the unit does not touch the ceiling: contact
may cause noise.
Ū Insulate the brackets (fig. 6) fixed on the unit with the insu-
lation supplied.
