RESISTOR 2526492 - Caterpillar

Do not clean or reuse filters. Use new filters when servicing the cab filtration system. Reusing filters can cause serious health hazards.
When cleaning equipment, care should be taken to prevent high-pressure water or high-pressure air from entering the ejection slots of the filter. Failure to do so can damage the filter cartridge.When replacing the filter, do not point ejection slots at a solid surface near the slots. Debris will be ejected from these slots at a high rate.
Replace filter when the cab pressure does not exceed 100 Pa when cab is sealed and fan speed is set at 6. Refer to Operation and Maintenance Manual, "Advanced Cab Filtration System"Machines with HEPA (H13) or MERV 16 particulate filter, change the filter after every 1000 service hours, even if the pressure monitor does not alert and there are no noticeable changes.Machine with Combination HEPA (H13)/ABEK1 rated gas filter, the site Health & Safety Officer is responsible for determining the fresh air filter change interval according to site-related variables.
