ORDINARY MAINTENANCE
The ordinary maintenance can be carried out by the user and
consists of a series of simple operations, which will ensure that
the fan coil unit operates at full efficiency.
Operations:
- External cleaning, to be done with a damp cloth (soaked in
water no hotter than 40 °C) and a neutral detergent avoid using
any other type of detergent or solvent.
Do not splash water on interior or exterior surfaces of the fan coil
unit (it could cause short circuits).
- Fil ter cleani ng , ever y two weeks or weekl y
i f i n s t a l l e d i n v e r y d u s t y e n v i r o n m e n t s .
Clean the filter with a vacuum cleaner and possibly with water
and a neutral detergent; avoid using any other type of detergent
or solvents.
- Visual inspection of the state of the fan coil unit for every
maintenance operation; any fault must be communicated to the
After-Sales Service.
SPECIAL MAINTENANCE
Special maintenance can only be performed by Aermec
After-Sales Services or by people with the technical and
professional expertise qualifying them to undertake installation,
modification, 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 protective wiring.
The special maintenance consists of a series of complex
operations that involve dismantling of the fan coil unit or its
components to ensure the maximum fan coil unit efficiency is
restored.
Operations:
- Internal cleaning, annually or after long periods of inactivity;
in environments where a high degree of air cleaning is required,
cleaning can be more frequent. This consists of: cleaning of the
coil, fan blades, drain pan and all the parts in contact with the
treated air.
- Repairs and setting up; when faults arise look at the
"TROUBLESHOOTING" chapter in this manual before calling the
After-Sales Service.
MAINTENANCE
For any problems not listed, contact the After-Sales Service immediately.
