Standard Filter Installation VAC-290
1. Turn the fi lter housing spacer assembly over on a table then fi t the fi lter over the fi lter shaker insert.
2. Make sure each pleat is fully supported and the ground wire is on the fi lter side of the assembly.
3. Connect the fi lter housing spacer assembly ground wire to the base via the push–on terminal.
4. Seat the fi lter housing spacer assembly on the base oriented as it was removed.
5. Seat the reverse pulse/motorized shaker assembly and housing spacer (if so equipped) on the fi lter housing spacer
assembly oriented as removed; make sure to connect the component ground wire to the fi lter housing spacer assem-
bly via push-on terminal.
6. Seat the HEPA adapter assembly and housing spacer (if so equipped) on the preceding housing component ori-
ented as removed; make sure to connect the component ground wire to the preceding assembly via push on terminal.
7. Connect the motor deck ground wire to the preceding assembly then seat the deck on the preceding housing
spacer.
8. Connect the clear differential pressure gage tubes to their respective barbed fi ttings if so equipped.
9. Turn the machine on then block the inlet with a fl at and rigid material to place the machine under vacuum pressure.
10. Secure all of the housing-components then turn the machine off.
HEPA Filter Replacement Procedure VAC-290
NOTE: All HEPA fi lter machines are equipped with a differential pressure gauge. The gauge measures the pressure
above against the pressure below the fi lter, thereby measuring the restriction of airfl ow due to contamination. HEPA
fi
lters should be replaced when the gauge consistently measures 4 inches W.C.
1. Turn the machine on then block the inlet with a fl at and rigid material to place the machine under vacuum pressure.
2. Remove the motor deck socket truss screws.
3. Turn the machine off and disconnect the power source.
4. Separate the motor deck and HEPA fi lter housing spacer then disconnect the motor deck ground wire from the
HEPA adapter assembly via the push-on terminal.
5. Remove the motor deck and silencer hood together.
6. Remove the lock nuts retaining the HEPA fi lter brackets.
7. Remove the ring-to-tab terminal, HEPA fi lter brackets and HEPA fi lter.
8. Center the new fi lter on the HEPA adapter plate gasket side down.
9. Position the provided lengths of self-adhering fl at gasket material on the HEPA fi lter frame (if not already done so)
to cushion the HEPA fi lter brackets.
10. ûıplace the HEP A fi lter brackets and ring-to-tab terminal then thread the locking nuts over the rods and tighten.
CAUTION: Do not over tighten. The effectiveness of the fi lter may be compromised if its frame is bent.
11. Set the motor deck on the HEPA fi lter housing spacer.
12. Connect the motor deck ground wire to the HEPA adapter plate assembly via the push-on terminal then seat the
deck on the HEPA fi lter housing spacer.
13. Connect the power source.
14. Turn the machine on then block the inlet with a fl at and rigid material to place the machine under vacuum pres-
sure.
15. Secure the motor deck then turn the machine off.
