MAINTENANCE
Filter care
The filters are not self-cleaning and must be maintained / cleaned / replaced as described below. Proper filter
care is essential for the effective operation of your AirBench. If in doubt, contact the manufacturer for advice.
When changing filters, the seals on which the filters sit should be checked for damage and replaced if
necessary.
All filters should be regularly checked for wear, damage, or by-passing.
When completing filter maintenance activities these should be recorded in the accompanying log sheet.
Take precautions and wear appropriate PPE when handing filters.
They may contain hazardous dusts.
i
If using a vacuum cleaner to empty filters, excessive cleaning will reduce filter life.
Remove excess dust only.
FILTER ACCESS
Prefilters are accessed by removing the top surface, taking care as the surface may have sharp edges. Once
the surface is removed, a retaining plate is exposed which holds the prefilters vertically in place. This can be
lifted out and filters rotated forwards for access as per the following diagram.
