MALFUNCTION
The fan does not activate even
if there is hot or cold water in the
hydraulic circuit.
The appliance loses water during
heating function.
Dew formations are present on the
front panel.
A few water drops are present on the
air outlet flap.
The appliance loses water during
cooling only function.
The appliance emits excessive
noise.
CAUSE
- The hydraulic valve remains
closed
- The ventilation motor is locked or
burned out.
- The electrical connections are not
correct.
- Losses in the water connection
of the system.
- Losses in the valves unit.
- The thermostatic valve integrated
in the connection unit between
panel and battery does not close
flow towards the wall.
- T h e r m a l i n s u l a t o r s a r e
disconnected.
- In situations of high relative am-
bient humidity (>60%) conden-
sation phenomenons may occur,
especially at minimum ventilation
speeds.
- The condensation basin is
clogged.
- The condensation drain has not
the necessary inclination for
correct drainage.
- The connection pipelines and
the valves unit are not insulated
correctly.
- The fan touches the structure.
- The fan is unbalanced.
SOLUTION
- Dismount the valve body and
check if water circulation is
restored.
- Check the operating status of the
valve by powering it separately at
220 V. If it activates, the problem
may be in the electronic control.
- Check the motor windings and
the free rotation of the fan.
- Check the electrical connections.
- Check the loss and firmly tighten
the connections.
- Check the status of the seals.
- Replace the junction which
integrates the thermostatic valve
in the water inlet upper unit.
- Check for correct positioning of
the thermoacoustic insulators,
paying particular attention to
the front one above the finned
battery.
- Once relative humidity drops, the
phenomenon disappears. In any
case, the possible fall of some
water drops inside the appliance
does not indicate a malfunction.
- Slowly pour a water bottle in
the bottom part of the battery to
ensure drainage; if necessary,
clean the basin and/or improve
inclination of the drain pipe.
- Check for insulation of the
pipelines.
- Check for possible interferences
by manually rotating the fan.
- U n b a l a n c i n g d e t e r m i n e s
excessive vibrations of the
machine: replace the fan.
