Set up locally filtered forced-air ventilation where the product is being
maintained, inspected or cleaned.
The filter cartridges must be checked at least every 6 months with a visual
inspection for wear and damage.
After 1000 operating hours at the latest, the filter cartridges must be replaced with
new ones.
This work should be done only by an expert wearing personal protective
equipment
After an extended period of operation, the filters clog up slowly due to the ingress
of extremely fine dust in the pores. Even the manual rotary cleaning system can
no longer remove this infiltrated dust. Filters must be replaced with new ones. This
work should be done only by an expert.
If possible, filter replacement must be done when there is no work going on. This
process requires 2 people with personal protective gear.
