UV Light Replacement (if
equipped)

1.

Disconnect the power.

2.

Locate the UV lamp located inside the enclosure.

3.

Rotate and remove the old UV lamp.

4.

Reinstall the new UV lamp.

5.

Power the unit up and try the new UV lamp.

Motorized Impeller Replacement

The motorized impeller must be replaced as a complete unit.
When the motorized impeller is replaced, the capacitor should also
be replaced. See Appendix A for Replacement Parts Diagram. See
Figure 6-3 for an isometric view of the motorized impeller plenum
assembly. The HEPA filter rests below the motorized impeller
assembly.

1.

Unplug the enclosure from the electrical outlet.

2.

Remove HEPA filter per the HEPA filter removal procedure
outlined earlier in this chapter.

3.

Consult the wiring diagram in Appendix C of the manual and
disconnect all the wires of the motorized impeller. Be sure to
connect wires on the new motor in the same way the old motor
was wired. The 3' and 4' enclosures have two motorized
impellers.

4.

Remove four screws in each motorized impeller.

WARNING: High-speed blower. Never operate
impeller with housing off.

5.

Replace each capacitor with a new one of equal voltage and
capacity.

6.

Reassemble each new motorized impeller by reversing the
assembly steps.

7.

Perform a HEPA filter leak check.
