Increase the water temperature beyond the
minimum limits indicated in “MINIMUM
AVERAGE WATER TEMPERATURE”.
For anomalies don’t hesitate, contact the after sales service immediately.
TROUBLE SHOOTING
Interventions:
- External cleaning must be carried out
weekly. Use a wet rag (with water at max,
40°C temperature) and neutral detergent;
avoid other detergents or solvents. .
- Do not spray water in the external or
internal surfaces of the fancoil (short cir-
cuit coud occur)
.
- Examination of the fancoil sta-
tus at any maintenance interven-
tion: any anomaly must be com-
municated to the After Sales dept.
MAINTENANCE
Routime maitenance can be performed by
the user. It consists of a series of simple
operations that allow the facncoil to
operatore at its maximum performance.
Before carrying out any intervention
be sure that electrical power supply
is disconnected. Do nor remove the
shell or the electrical or mechanical
protections.
Intervention:
- Internal cleaning with year frequence or before prolonged
period. In particular situation where an high level nof cleaning
is requetsed, it can be carried out more frequently. It consists in
the coil cleaning, fancoil fins, drip tray, ioniser and all the parts
in contact with the treated air. Moreover verify the status of the
filter, clean it and if necessary replace it.
For cleaning do nou use jets or water spray..
Use a small brush to remove possible dust deposit.
- For repairing or setting operation, consult the TROUBLE AND
SHOOTING chapter before contact the After Sales dept.
Only Aermec After Sales dept. or
personnel with all the technical-
professional capacities for the
installation,transformation and
maintenance of the units and able
to verify them according to the safety
normes in force with particular reference
to electrical connections can carry out
the extraordinary maintenance. The
following verifications relating to the
above are requested:
- Measure of the electrical unit
insulatioon resistance.
- Continuity testo of the protection
conductors.
Extraordinary maintenance consists of a
series of complex operations that involve
the disassembling of the fancoil or its
components. Thanks to this operation
the maximum efficency condition for the
bfan coil functioning is restored.
Before any intervention, be sure
electrical power supply is disconnected.
