AND REMEDIES
EFFECT
A delayed activation of the
ventilation respect to the new
temperature or function settings.
The appliance does not activate
the ventilation.
The ventilation does not activate
even if there is hot or cold water
in the hydraulic circuit.
The appliance leaks water during
the heating function.
There are formations of dew on
the front panel.
There are drops of water on the air
outlet grill.

TABLE OF ANOMALIES AND REMEDIES

CAUSE
The circuit valve needs some time
to open and as a result the hot or
cold water takes time to circulate
in the appliance.
No hot or cold water in the system.
The hydraulic valve remains
closed.
The fan motor is blocked or burnt
out.
The micro-switch that stops the
ventilation when the filter grill is
opened does not close correctly.
The electrical connections are not
correct.
Leaks in the hydraulic connections
of the system.
Leaks in the valve unit.
Thermal insulation unstuck.
In situations of high humidity
(>60%) condensation could form,
especially at the minimum
ventilation speeds.
The condensation bowl is blocked.
The condensation discharge does
not need an inclination for correct
drainage.
The connection pipes and the
valve unit are not insulated well.
The fan touches the structure.
The fan is unbalanced.
Check the clogging of filters and
clean them if necessary
REMEDY
Wait for 2 or 3 minutes to open
the circuit valve.
Check that the water boiler or
cooler are functioning correctly.
Dismount the valve body and
check if the water circulation is
restored.
Check the working efficiency of the
valve by powering it separately with
230V. If it activates the problem
could be the electronic control.
Check the windings of the motor
and thefree rotation of the fan.
Check that by closing the grill the
micro-switch contact is activated.
Check the electrical connections.
Check the leak and fully tighten
the connections.
Check the state of the gaskets.
Check the correct positioning of
the thermo-acoustic insulation
paying attention to that in the
front above the finned battery.
As soon as the humidity starts fal-
ling the phenomenon disappears.
In any case the presence of a few
drops of water in the appliance
does not indicate a malfunction.
Slowly pour a bottle of water in
the low part of the battery tocheck
the drainage; if necessary, clean
the bowl and/or increase the
inclination of the drainage pipe.
Check the insulation of the pipes.
Check the clogging of filters and
clean them if necessary.
The unbalancing causes exces-
sive vibrations of the machine;
replace the fan.
Clean the filters.
