13 - MAINTENANCE
13.1 - Filters
Check the lters frequently when commissioning the unit. The rate at which they will clog will depend on how well the air circuits were
cleaned.
Frequency of servicing
The lter life depends essentially on the amount of dust in the air and the eciency of the ltration system. The ltration quality cannot
be maintained if the lter medium has been damaged during maintenance. We recommend that the lters be replaced once every two
years, even in case of low to moderate use.
Replacing the lter elements
When performing maintenance, it is important to avoid releasing and spreading the dust that has accumulated in the lter.
Turn o the unit.
Access the lters by opening the doors on the front.
For lters for sizes W40 to W100
Replace the used lters by new lters. Take care to note the direction of air ow indicated on the new lters.
Always make sure that the lter elements are properly positioned before compressing them or turning the unit back on.
