10. Position the new HEPA filter into the unit with the gasket on the
filter facing up, on the discharge side of the filter. Make sure the
HEPA filter is centered and the edges align with the brackets on the
top side and each side for a complete seal.
11. Re-install the bottom supports, all-thread rods, and attach the
bottom nuts.
12. Tighten the nuts equally until the filter is held securely in place, and
ensure the top HEPA filter gasket is significantly compressed
against the mounting structure to assure no bypass air.
13. Inspect the filter for a complete and tight fit. Loosen the nuts and
reposition if necessary.
14. Replace the pre-filter.
15. Replace the doors. Lift the unit into an upright position.

WARNING
!
ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal injury or death.
Disconnect all electrical power to the unit before removing access
panels to perform any maintenance.
For models 006 and 015, if you desire different airflows from the
factory-set Low, Medium, and High (taps 1, 3, and 4), do these steps:
1. Move the power switch to the OFF position.
2. Unplug the unit from the wall outlet.
3. Listen to make sure the blower wheel has stopped spinning, and
loosen the screws attaching the bottom door, but do not remove.
4. Remove the screws attaching the upper door and allow it to gently
swing down and rest, supported by the wire harness attached to the
front panel.
5. Locate the three blower speed tap wires (red, blue, and gray)
attached to the blower motor

(Fig.

6. Identify the correct Motor Tap for desired airflows and connect the
wires according to
– The Red motor lead is energized when switch is set to LOW, the
Blue motor lead is energized when switch is set to MED.
NOTE: The Blue and Gray motor leads are energized when switch is set
to HIGH. The factory HIGH speed setting is tap 4; this is assuming the
product will be operated in Scrubber mode with an accessory diffuser. If
this is not the case, the Gray lead should be moved to tap 5 to assure that
red filter/obstruction indicator is properly detecting filter condition.
7. Replace the top door screws.
8. Tighten the bottom door screws.

Altitude Adjustments
Depending on your location, you may see up to 10% increase of
measured airflow at higher altitudes. To compensate, you can change
motor taps for alternate airflows
Troubleshooting
Before you request dealer service, check for these easily solved
problems:
• Check your main electrical panel circuit breakers or fuses if the unit
will not turn on.
• Make sure the unit is plugged in to a working 115V electrical outlet.
• Check for sufficient airflow. Filters should be clean and unobstructed.
If you need to contact your authorized dealer for troubleshooting and/or
repairs, be sure to have the model and serial numbers of your equipment
available.
