MAINTENANCE

ROUTINE MAINTENANCE
Routine maintenance can be carried
out by the user: it involves a series
of simple operations, thanks to
which the fan coil can operate at its
maximum efficiency level.
Interventions:
- External cleaning, weekly to be car-
ried out with a moist cloth and
neutral soap; do not use other
detergents and solvents of any
type.
- Frequent cleaning of the filter
ensures greater operating effi-
ciency. Check if the filter is very
dirty: if you need to repeat the
operation, clean frequently,
remove the accumulated dust
with a vacuum cleaner. When the
filter is clean, put it back on the
fan coil unit.
- Visual inspection of the state of the
fan coil for every maintenance
operation; every fault must be
communicated to the After Sales
Service department.

TROUBLESHOOTING

PROBLEM
Insufficient air flow at
outlet
Unit does not heat
Unit does not cool
Fan not turning
Condensation forming
on the external case of
the unit
For any problems not listed, contact the After Sales Service immediately.
EXTRAORDINARY MAINTENANCE
Extraordinary maintenance can only
be performed by Aermec After-
Sales Services or by people with
the technical and professional req-
uisites qualifying them to under-
take installation, conversion,
expansion and maintenance of
the systems and are able to check
them in terms of safety and func-
tionality, in particular with regard
to electrical connections the fol-
lowing tests are required relative
to:
- Measurement of the electrical sys-
tem insulation resistance;
- Continuity of the protection wires
Extraordinary maintenance consists
of a set of complex operations that
involve the dismantling of the fan
coil or its components, resulting
in the restoration of the fan coil's
functioning at maximum efficiency.
Interventions:
- Internal cleaning, annually or before
shutting down for long periods;
cleaning can be more frequent
PROBABLE CAUSE
Incorrect speed setting on control panel
Blocked filter
Obstructed air flow (inlet and/or outlet)
No hot water
Incorrect control panel setting
No cold water
Incorrect control panel setting
No electrical power
Water has not reached operating temperature.
Temperature and humidity limits specified by
"MINIMUM AVERAGE WATER TEMPERATURE" have
been reached
in environments where a high
degree of air cleaning is required;
it consists of cleaning the coil, the
removable volute, the fan fins, the
basin and all the parts in contact
with the treated air.
- Repairs and fine tuning: if you
notice anomalies, consult the
"TROUBLESHOOTING" charter of
this manual before contacting the
After Sales Service.
SOLUTION
Select the correct speed on the control panel
Clean the filter
Remove the obstacle
Check the boiler
Set the control panel
Check the chiller
Set the control panel
Check that there is electrical power
Check heater or chiller.
Check thermostat setting
Raise the water temperature above the
limits specified by "MINIMUM AVERAGE
WATER TEMPERATURE"
