- Check the air intake and discharge grilles
for contamination and clean them if nec-
essary.
- Check the heating elements and the fans
for dust and other contaminants. Clean
them if necessary.
- Check the working of the fan.
For units with water heating and/or cooling:
- Check for water leaks. If there is a leak,
disconnect the unit from the mains, and
repair the leak.
- Check if the water circuit contains any
entrapped air. If yes, vent the circuit.

densate tray (accessories) are clean.
Contamination may lead to poor drain-
age and to growth of bacteria and fungi.
- Clean the filter of any condensate pump
(accessory) in the float module.
For units with air valve module:
- Check if the ventilation valve closes
properly in both modes.
- Check if the valve closes automatically if
the power supply is interrupted.
