HEPA Filter Removal and Installation

NOTE: All HEPA ﬁ lter machines are equipped with a differential pressure gage. The gage 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 gage 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. Remove the motor deck and silencer hood together.

5. Remove the four lock nuts retaining the two HEPA ﬁ lter brackets.

6. Remove the HEPA ﬁ lter brackets and HEPA ﬁ lter.

7. Center the new ﬁ lter on the HEPA adapter plate gasket side down.

8. Position the provided lengths of self-adhering ﬂ at gasket material on the HEPA ﬁ lter frame (if not already done) to

cushion the HEPA ﬁ lter brackets.

9. Replace the HEPA ﬁ lter brackets 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.

10. Seat the motor deck on the HEPA ﬁ lter housing spacer.

11. Connect the power source.

12. Turn the machine on then block the inlet with a ﬂ at and rigid material to place the machine under vacuum

pressure.

13. Secure the motor deck then turn the machine off.

Motor Deck Inspection

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. Remove the silencer hood assembly and motor deck separately.

CAUTION: The motor deck of this unit can be very heavy. Follow safe lifting procedures.

5. Turn the motor deck over on a table to inspect the belt for cracks, ware, melt, stretch and tension (make sure to

support the motor and turbine equally).

6. Use a knife to clear the three turbine mounting slots of silicone.

7. Loosen the three nuts securing the turbine enough to slide the turbine forward.

8. Remove the belt.

9. Check the turbine and motor bearings for noise by hand.

Belt Installation

1. After the preceding motor deck inspection.

2. Place the belt over both pulleys making sure to match the grooves in the belt with both pulleys.

3. Use a spanning device between the turbine and motor pulleys to tension the belt.

4. Maintain tension while tightening the three nuts that secure the turbine.

5. Check that the corresponding grooves on the turbine and motor pulleys are aligned using the motor deck as a

reference plane.

NOTE: The pulleys are normally aligned at the factory, but if adjustment is needed remove the motor pulley to access

to the relevant shims.

6. Seat the motor deck on the housing spacer.

CAUTION: The motor deck of this unit can be very heavy. Follow safe lifting procedures.
