FILTER
The safety switches must be switched off and locked after the unit has been switched
off before starting any service work.
Function:
The filter prevents dust and dirt from entering the unit and into the supply air. The
function of the filter is therefore important for the service life of the unit, as well as for
economic and occupational safety reasons.
Check:
• If the filters needs to be replaced. H. Östberg AB recommends changing
the filters at least two times a year.
• If the filter locker is dirty.
• That the filter locking is functioning properly.
• That the filter seal strip is intact.
Action:
• Remove the filter by pulling the handles
for the two filter rails.
Pull out the filter carefully so the dust
and dirt doesn’t come off.
• Vacuum the area around the filter if needed and/or wipe with a cloth with
a few drops of detergent. Never use solvent to clean the unit.
• Lubricated the eccentric washers when needed.
These should move easily.
• Replace the filter seal strip if it is damaged
or has been dislodged.
