12. Place new throwaway liner inside drum on top of primary filter.
Position liner so the seam is 180º opposite the primary filter seam.
Allow ends to butt together, do not overlap. Smooth out wrinkles.
13. Replace inlet cover and secure latch.
In some applications where extreme contamination of the permanent
filter makes it impossible to clean, the filter should be replaced with a
new one smoothing it and butting ends evenly. If unit vibrates, the
filter may have to be refitted with the open ends at a different location.
When finally located, secure permanent filter with mounting buttons
adjacent to the seam and an equal number 180º (opposite) from
the seam.

1. Turn off power and lock out.
2. Remove bolts holding the motor mounting plate to the housing.
3. Lift out the motor and drum assembly.
4. Remove the screws holding tapered bushing to hub on drum.
Reinstall screws in tapped holes in bushing and tighten evenly

6.4 Cleaning Procedure - Sizes AS-100 and Larger (Figures 7,8)
1. Turn off power and lock out.
2. Unlatch and remove inlet cover.
3. Remove throwaway filter liner from drum.
4. Inspect primary filter in drum. If filter is dirty, proceed with Step 5.
If filter is clean, skip to Step 11.
5. Remove screws holding tapered bushing to hub on drum.
Reinstall screws in tapped holes in bushing and tighten evenly
until bushing is loose. Bushing, drum, key, and key retainer may
then be removed.
CAUTION: Do not use aromatic hydrocarbon or solvents or ketone
solvents. Do not use any toxic solvents since toxic vapors may be
discharged from residual solvent left in filter when unit is restarted.
6. Immerse drum assembly with the permanent filter intact in
kerosene or detergent. Agitate assembly till clean, being careful
not to damage drum or impeller blades.
7. If possible, spin dry.
8a. For sizes AS-100 through AS-300: Support motor and remove the
four (4) hex head screws that mount the motor in place. Pull out
retainer screen and secondary filter. Rinse secondary filter in
solvent and wipe retainer screen clean. Allow filter to dry.
8b. For sizes AS-400 and up: Removes two (2) of the hex screws that
mount the motor. This will release the secondary filter retainer and
still hold the motor in place. Remove the retainer and pull out the
retainer screen, secondary filter and E-Z Kleen. Rinse secondary
filter and E-Z Kleen in solvent and wipe retainer and retainer
screen. Allow filter to dry.
9. Using a rag soaked with a mild solvent, clean the inside and
outside of the casing and the outside of the motor. Check drain to
make sure opening is not restricted.
10. Replace the E-Z Kleen (sizes AS-400 and up only), secondary
filter, retainer screen, and retainer in this order. Fasten retainer
to motor.
11. Replace drum, tapered bushing, key, and key retainer on motor
shaft. Align end of bushing with end of motor shaft and tighten
screws evenly until drum is secured to motor shaft.
