Airflow Adjustments
For models 006 and 015, if you desire different airflows from the
factory-set Low, Medium, and High (taps 1, 3, and 5), 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 ).
6. Identify the correct Motor Tap for desired airflows and connect the
wires according to Table 2 .
– 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 Gray lead should remain on Motor Tap 5 in order to
assure that red filter/obstruction indicator is properly detecting filter
condition.

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 (Airflow Adjustments on p4) .
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.
