2. If the lights are working, then tum the blower
switch off and let the cabinet rest for ten
minutes. When the time has passed, tum the
blower switch on again. If the blower starts,
you kndw there has been overheating of the
blower motor. Also check the wiring
connections inside the right end of the light
canopy which connect the canopy to the
cabinet. Be sure the connections are pushed
together.
3. If these solutions do not correct the problem,
or if the blower failed to start after the rest
period, then either the speed control, blower
motor or capacitor is defective. A qualified
electrician
can find out if the speed control is
defective by bypassing it, using the wiring
diagram in the Appendix of this manual as a
guide. If there is a noise problem, it may be
caused by faulty motor bearings.
If one (or both) of the electrical outlets does not
function-
1. Be sure the outlets on/ off switch has been
pressed. The yellow indicator above the

2. Both
outlets are equipped with ground fault
interrupters. If the button on the G. F.!. outlet
has popped out, press it in to reset.
3.
The outlets are also protected by a self-
resetting thermal circuit breaker. Check this
breaker.
If the ultraviolet light does not work -
1. Be sure t_.1-lat t.l-te l,r]e-.;,vscreen is completely
closed, and the fluorescent light is off.
2. Check the ultraviolet bulb and lamp sockets
for
good electrical connections.
3. Change the ultraviolet light bulb.
4. Hcn/e a qualified electrician check the vviring
and baUast for continuity'. The vvirin,g can be
traced to the source of a break If none of the
abcYve is effective, the ballast rnay need
replacing.

When there is uneven fan operation, or noise
from the motoriblower assembly-
l. lt may be necessary to decontaminate the
cabinet.
2. Look for loose objects in the fan cage.
3. Check to see if the fan wheel is contacting the
blower housing.
4. Remove wing nuts and drop canopy to open
(full restraint) position. Check the multi-pin
connectors at each end to be sure they are
securely engaged.
5. Another possible source of the problem is the
speed control.
When the viewscreen open alarm is sounding -
1. The viewscreen alarm should be silent in only
two positions. The first silent positior, is
when the viewscreen is at its proper
operating height (8" standard). The second
silent position is when the viewscreen is in a
closed position. The
viewscreen alarm is
located
in the light canopy and is de-activated
when it senses hidden magnets attached to
the viewscreen frame.
2. If the viewscreen is in an incorrect position,
the alarm will sound. The indicator above
the alarm reset button will flash. You may
cancel the audible alarm for five minutes by
pressing the alarm reset button. The
indicator will continue to flash until the
viewscreen is set in the correct position.
After five minutes, the alarm will sound
again. You may press the alarm reset button
a gaul.
If the fluorescent light does not work -
l. The blower switch should be turned on, and
the yellow indicator above the switch should
be lighted
Rernove \-Vi.ng nuts and drop G1nopy to upen

com1ectors at each end to be sure they are
securely engaged. If the larnp flickers and
can be corrected by vigorous rubbing of t11e
bulb, there is probably an in1proper ground.
