MAINTENANCE
ORDINARY MAINTENANCE
The ordinary maintenance, it can also be done by the user,
consists of a series of simple operations, thanks to which the
fan coil can operate at full efficiency.
Operations:
- External cleaning, weekly, to be done with a damp cloth
(soaked in water no hotter than 40 °C) and neutral soap;
avoid using any other type of detergent or solvent.
Do not splash water on interior or exterior surfaces of the fan
coil (it could cause short circuits).
- Fi l t e r c l e a n i n g , e ve r y t wo w e e k s o r w e e k l y

Clean the fi lter with a vacuum cleaner and possibly with
water and neutral detergent, do not use detergents or
solvents of any kind.
- Visual inspection of the state of the fan coil for every
maintenance operation; every fault must be communicated
to the After-Sales Service.

EXTRAORDINARY MAINTENANCE
Extraordinary maintenance can only be performed by
Aermec After-Sales Services or by people with the technical
and professional requisites qualifying them to undertake
installation, conversion, expansion and maintenance of
the systems and are able to check them in terms of safety
and functionality, in particular with regard to electrical
connections the following tests are required relative to:
- Measurement of the electrical system insulation resistance.
- Continuity test of the protection wires.
The extraordinary maintenance consists of a series of
complex operations that involve the dismantling of the fan
coil or its components thanks to which the condition of
maximum fan coil functioning efficiency is restored.
Operations:
- Internal cleaning, annually or after long periods of non
use; in environments where a high degree of air cleaning
is required, cleaning can be more frequent; consists of the
cleaning of the coil, ventilator fins, basin and all the parts in
contact with the treated air.
- Repairs and fine tuning, when faults arise look at the
"TROUBLESHOOTING" chapter in this manual before
calling the After-Sales Service.
