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.

The solvent does not pump

adequately through the system

and escaping air can be heard.

The internal air hose suppling the air pump may be leaking.

Re-secure, with a new hose clamp, or replace with a new hose

if necessary.

The purge process was not

adequate.

The shop air is below 90 psi. Adjust the shop air pressure to

at least 90 psi.

The coalescing filter may be clogged and need to be replaced.
