TROUBLESHOOTING
U A
In the event of water leaks o malfunctions, move the
main system switch to the “off” position and close the
water taps.
If one of the following faults occurs, contact the technical
service or a qualified professional as soon as possible.
Do not attempt to repair the appliance yourself.
- The fan does not start active even when there is hot or
cold water in the circuit.
- Water leaks from the appliance in heating mode.
- Water leaks from the appliance in cooling mode only.
- The appliance is very noisy.
- Dew forms on the front panel.
TROUBLESHOOTING TABLE
U A
The following operations must be performed by a qualified installer or a specialist service centre.
TIPS ON SAVING ENERGY
I A
- Keep the filters clean at all times;
- where possible, keep the doors and windows in the air-
conditioned room closed;
- where possible, in cooling operation limit exposure of the
air-conditioned room to direct sunlight (use curtains, shut-
ters, etc.).
Fault
Possible cause
Solution
The fan starts after a delay from changing the
temperature settings or function.
The circuit valve takes some time to open and
let hot or cold water circulate in the appliance.
Wait 2 or 3 minutes for the circuit valve to
open.
The fan does not start.
No hot or cold water in the system.
Make sure that the boiler or water chiller are
operating.
The fan does not start active even when there
is hot or cold water in the circuit.
The water valve remains closed
Remove the valve body and check if water
starts circulating.
Check valve operation by powering it sepa-
rately at 230 V.
If the valve is activated, the problem may lie in
the electronic controller.
The fan motor is blocked or burnt out.
Check the motor windings and make sure the
fan can spin freely.
The microswitch that stops the fan when
opening the filter grill does not close correctly.
Make sure that when closing the grill, the
microswitch contact is activated.
Incorrect electrical connections.
Check the electrical connections.
Water leaks from the appliance in heating
mode.
Leaks from the system water connections.
Check the leaks and fully tighten the connec-
tions.
Leaks from the valves.
Check the gaskets.
Dew forms on the front panel.
Heat insulation detached.
Make sure that the heat insulation/sound-
proofing is positioned correctly, especially at
the front above the finned coil.
There are droplets of water on the air outlet
louvers.
When relative humidity inside the room is
quite high (>60%), condensate may form,
especially at low fan speed.
When the relative humidity falls, the phenom-
enon will disappear.
In any case, the formation of some droplets of
water inside the appliance does not indicate a
malfunction.
Water leaks from the appliance in cooling
mode only.
The condensate pan is blocked.
Slowly pour a bottle of water into the bottom
of the coil to check drainage; if necessary,
clean the pan and/or increase the slope of the
drain pipe.
The condensate drain is not sloped down-
wards enough for correct draining.
The connection pipes and valves are not
properly insulated.
Check the insulation on the pipes.
The appliance is very noisy.
The fan is touching the structure.
Check the filters and clean them if necessary.
The fan is unbalanced.
An unbalanced fan will cause excessive vibra-
tions on the unit: replace the fan.
Check the filters and clean them if necessary
Clean the filters
The louvers stay open.
Possible obstruction blocking rotation.
Remove the obstruction, power off the appli-
ance, wait 2 minutes and power the appliance
on again. The louvers close correctly.
Power failure or disconnection during move-
ment of the louvers.
Restore power to the appliance.
