Solvent Replacement
To avoid excessive foaming and potential contaminant carry-over, it
is recommended the solvent be changed after each job. It is strongly
recommended that the used solvent be removed from the machine immediately
after a FLUSH/PURGE cycle.
1. Place the end of the discharge hose in a suitable waste container.
2. Verify the selection valve is OFF and shop air is connected.
3. Turn the selection valve to FLUSH.
4. Turn the selection valve to OFF when the solvent is evacuated from the
machine.
Solvent Filter Replacement
Replace the solvent filter each time the solvent is replaced. A non-bypass filter,
such as Motorcraft FL1A, Purolator L30001, Champ PH-8-A, or equivalent,
should be used.
1. Open the back door of the unit’s protective covering.
Note: To unlock the door, turn the two screws 1/4 turn counterclockwise.
2. Remove the filter by turning it counterclockwise.
3. Hand tighten the new filter in a clockwise direction.
Carbon Filter Element Replacement
The carbon filter element should be replaced when odors become noticeably
stronger during the purge cycle.
1. Remove the filter retaining plate by removing the wing nut on the filter
housing.
2. Remove and replace the filter element.
3. Replace the filter retaining plate and wing nut.
Coalescent Filter Element Replacement
If oil is visible in the coalescing filter bowl, it can be drained by toggling the
valve on the bottom of the bowl.
The coalescent filter element can be replaced as follows:
1. Open the back door of the unit’s protective covering.
Note: To unlock the door, turn the two screws 1/4 turn counterclockwise.
2. Push up on the filter bowl, and turn the bowl 1/8 turn counterclockwise to
disengage the bowl from the filter housing.
3. Remove the filter element by unscrewing the nut on the bottom of the
filter.
4. Install the new filter element, followed by the filter bowl.
