The RTI Spin-on Filter should be replaced after each flushing procedure.
This filter must be replaced with an RTI brand Spin-on filter.
1. Locate the Spin-on Filter on the rear of the ACF.
2. Turn the filter counterclockwise and remove it.
3. Apply a small amount of lubricant to the filter gasket and install the new filter. Take
caution to hand tighten only.

Charcoal Air Filter Replacement
The charcoal air filter element, located on the rear of the unit, should be replaced after every 25 flush and purge services. It may be necessary to replace the element sooner if the operator notices a stronger than usual odor emitted from the unit during the purge process.
1. Turn the wing nut on the filter counterclockwise and remove the retaining plate.
2. Remove the old filter element and replace with a new one.
3. Replace retaining plate and tighten wingnut to finger tight only.
Coalescing Filter Element Replacement
The coalescing filter element must be replaced after every 100 flush and purge services. In some cases the element may need to be replaced sooner if the shop air supply contains high amounts of moisture and oil. A clogged element will restrict the airflow in the purge process and should be replaced immediately.
1. Turn counterclockwise on the filter bowl to remove it.
2. Remove the filter element by turning it counterclockwise.
3. Replace the used element with a new one. Hand tighten only.
4. Replace the filter bowl by turning it clockwise.
