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.
