PROBLEM
Insufficient air flow at out-
let
Unit does not heat
Unit does not cool
Fan not turning
Condensation forming on
the external case of the
unit
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 the operating temperature
Air has not reached the operating temperature
Temperature and humidity limits specified by
“MINIMUM AVERAGE WATER TEMPERATURE” have
been reached
SOLUTION
Select the correct speed on the control
panel
Clean the filter
Remove the obstacle
Check the boiler
Check the heat pump
Set the control panel correctly
Check the chiller
Set the control panel
Check that there is electrical power
Check the boiler or chiller and/or its setting
Check the temperature set on the thermostat
Raise the water temperature above the limits
specified by “MINIMUM AVERAGE WATER
TEMPERATURE”
For any problems not listed, contact the After Sales Service immediately.
TROUBLESHOOTING
Interventions:
- External cleaning, weekly, to be carried
out with a damp cloth (dipped in water
maximum 40°C) and neutral soap; avoid
any other type of detergent or solvent. - Do not spray water on the outer or
inner surfaces of the fan coil (this could
cause short-circuiting). - Visual inspection of the state of the fan
coil for every maintenance operation;
any anomaly must be reported to the
After Sales Service.
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. Before carrying out any work, make
sure the electricity supply is unplugged.
Do not remove the shell or the
mechanical/electrical protection
devices.
Interventions:
- Internal cleaning, once a year or before the machine is shut
down for a long period. In rooms where a high level of air
cleaning is requested, the cleaning intervention can be made
more often. It consists in the cleaning of the coil, fan louvres,
basin, ioniser, and all the parts in contact with the treated air.
Check also the condition of the filter, cleaning or replacing it if
necessary. Do not use jets or sprays of water during the cleaning.
Use the brush to remove any dust deposits.
- Repairs and fine tuning: if you notice anomalies, consult the
“TROUBLESHOOTING" chapter of this manual before contac-
ting the After Sales Service.
Extraordinary maintenance must only
be carried out by Aermec After Sales
Service centres, or by technicians with
the technical and professional requisites
for the installation, transformation,
amplification and maintenance of the
systems, and able to check these aspects
in terms of safety and good working. For the electrical wiring in particular,
checks relating to the following aspects
are required:
- Measurement of the electrical system
insulation resistance;
- Continuity test 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.
Before carrying out any work, make
sure the electricity supply is unplugged.
