
Check to make sure the unit is plugged into a dedicated electrical outlet (grounded 20
amp, 115 Volt AC, 60Hz).

Check to make sure the wiring connections inside the left end of the light canopy are
pushed together properly.

Check to see if the lights are working. If they are, then turn the blower switch off and let
the cabinet set for ten minutes. This allows the motor time to reset itself, if it has been
overheated.
Note: if the motor restarts and there is a whining sound, the motor bearings may be
causing the motor to overheat.

If these solutions do not correct the problem, or if the blower failed to start after the rest
period, then the speed control, blower motor or capacitor is defective. A qualified
electrician, using the wiring diagram in the Appendix of this manual, can by-pass the
speed control to determine if it is defective.
If one (or both) of the electrical outlets does not function -

Check to make sure the outlet switch is in the on position. The yellow indicator below the
switch should be on.

Check the reset button on the GFCI outlet. If the GFCI has tripped out, press the reset
button.

The outlets are also protected by a self-resetting thermal circuit breaker. A qualified
electrician, using the wiring diagram in the Appendix of this manual, can check this
breaker.
If the ultraviolet light does not work -

Ensure that the window is completely closed and the fluorescent light is off.

Check for proper electrical connections between the ultraviolet bulb and lamp sockets.

Check the ultraviolet light bulb; replace if necessary.

Have a qualified electrician check the wiring and ballast for continuity. The wiring can be
traced to the source of a break. If none of the above is effective, the ballast may need
replacing.
When there is uneven fan operation, or noise from the motor/blower assembly -
NOTE: it may be necessary to decontaminate the cabinet.

Check the speed controller.

Lower the light canopy from the unit and check the multi-pin connectors at each end to be
sure they are securely engaged.

Check the blower wheel for contact with the blower housing.

Check the blower for loose objects.
When the window open alarm is sounding -

Check to ensure the window is at the correct position. The alarm should be silent when
the window is at the proper design opening. The indicator below the alarm-reset button
will flash. You may cancel the audible alarm for five minutes by pressing the alarm-reset
