In order for the installation to operate correctly, it is essential to regularly clean the air lter located in the
intake of the indoor unit.
When clogged, the lter reduces the air ow through the heat exchanger of the indoor unit, which in turn
reduces the efciency of the installation and inhibits the cooling of the fan motor.
Check the cleanness of the indoor heat exchanger.
18.1.5. AIR FILTER
The lters must be changed at regular intervals. The frequency is dependent on the specic application
conditions. Certain installations, for example in hotels where there large amounts of uff due to the frequent
bedding changes and the presence of tted carpets, require more frequent lter changes. It is recommended
that the lters are checked every 60 days during the rst year of operation in order to determine the
frequency required. If it is not possible to see light through the lter when it is held up to the sun or in front
of a strong light, the lter must be replaced. A more rigorous standard of cleanliness may be required.
18.1.6. FAN MOTOR ASSEMBLY
There is no particular maintenance on fan and motor assembly. All fan coil units utilize permanently lubricated
fan motor bearings.
However during periodic maintenance, check that fan wheel does not touch the housing and adjust, if
necessary, clearance.
If fan motor overload protection open, wait for automatic overload reset and try to determine the cause.
The fan coil unit shall have a lter installed in the return air side. The attachment systems must be
relocked in place after changing the lter.
Non compliance with these instructions can affect the unit’s electrical safety and render the qualied
personnel performing the work liable for any ensuing damage.
