Empty Solvent Tank
The flush solvent may be used to flush up to 20 components. The number of components
flushed will depend on the degree of contamination of the components. Remove used flush
solvent from the ACF as follows:
1. Turn the Control Valve to OFF.
2. Place an adapter fitting on the ”IN”
Hose and place it into a waste
container.
3. Turn the Selector Valve to PURGE.
4. Turn the Control Valve to FLUSH.
5. Verify that the ACF is completely drained
before continuing.
6. Turn the Control Valve to OFF.
7. At this point the RTI Spin-on Filter needs to
be removed and replaced. (Refer to page 7)
Page 8
RTI Spin-on Filter Replacement
NOTE:
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.
Page 9
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.
