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).

v e r 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.

Blocked filter

Obstructed air flow (inlet and/or outlet)

No hot water

Incorrect control panel setting

T water > 90°C

No cold water

Incorrect control panel setting

No electrical power

Water has not reached operating temperature.

been reached

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.
