Special maintenance must be performed only
by Aermec After-sales Service or by person-
nel with the technical-professional skills for
installation, transformation, extension and
maintenance of the systems. Moreover, they
must be able to check the systems for safety
and functionality purposes. In particular, elec-
tric connections
require the following checks:
• Measurement of the electric system iso-
lation
• resistance.
• Continuity test of the protection wires.
• Special maintenance consists of a series
of complex
operations that involve the removal of the
fan coil and its components, thanks to which
the conditions of maximum efficiency are re-
stored
in the fan coil operation..
Make sure that the power supply has
been disconnected before carrying out any
interventions.
Removing the augers of the inspected fans (which can be carried out only
by qualified personnel) allows the internal parts to be cleaned accurately.
This is essential for installation in very crowded areas or that require high
hygienic standards.
EXTRAORDINARY MAINTENANCE
In the event of abnormal operation,
switch off the power supply to the
unit, then power it on again and
restart the appliance.
WARNING! Do not try to repair the unit
yourself, it is very dangerous!
If the problem occurs again, call the
local Assistance Service immediately.
