m
aintenance and cleaning
For safety reasons before carrying out any maintenance or cleaning operation,
turn off the unit and cut the voltage by turning the line switch to OFF.
Maintenance
The maintenance operations for the FWB air conditioner and hot-air heating units
are limited to the periodic cleaning of the air filter and the heat exchanger, and the
checking of the working efficiency of the condensate discharge.
Only skilled personnel may perform the maintenance.
Pay utmost attention during the maintenance operations: accidentally coming into
contact with some of the metallic parts might cause injuries, therefore use safety
work gloves.
Every time the units are started after a long idle period, make sure that air is NOT
present in the heat exchanger.
The motor is maintenance-free since it is equipped with self-lubricating bearings.
Cleaning the air filter
Cut voltage to the unit by turning the line switch to OFF.
For cleaning the air filter proceed as follows:
• Access the equipment through the inspection panel and remove the air filter
as shown in figure 7 by unscrewing the fixing knobs.
• Wash the filter with lukewarm water or, for dry powders, with compressed
air.
• Reassemble the filter after having it dried up.
Cleaning the heat exchanger
It is advisable to check the condition of the heat exchanger before the start of the
summer season. Also check if the fins are not clogged by impurities.
To access the heat exchanger, remove the delivery panel and the condensate tank.
Upon having accessed the heat exchanger, clean with compressed air or low
pressure steam, without damaging the fins of the heat exchanger.
Before operating it in the summer, check the condensate discharges regularly.
