LAMP REPLACEMENT PROCEDURE
Unplug unit from the electrical outlet before starting replacement procedure.
NOTE:
Wear oil-free cotton gloves prior to procedure in case of accidental breakage of glass.
1. Rotate the CX-Aire ballast assembly counterclockwise
until it stops (Figure 19).
2. Remove the ballast assembly and lamp from the
mounting base (Figure 20).
3. Remove the lamp from the lamp socket (Figure 21).
4. Install the replacement lamp into lamp socket. Do not
handle the lamp with bare hands. Oils on the hands
tend to reduce lamp intensity.
5. Wipe off the glass with the supplied alcohol wipe.
6. Position the ballast assembly power cord 90 degrees
to the viewport hole on the mounting base and press
the ballast against the mounting base. Rotate the
ballast assembly clockwise until it stops and is locked
in place (Figure 22).
7. After assembly is firmly in place, plug the power
supply cord back into the standard electrical outlet.
Check lamp operation by looking through the viewport
hole. A blue glow should be seen in the duct.
8. After replacing the lamp, make sure to install the
Lamp Replacement Label. Print the date on the label
and apply to the side of ballast assembly.
NOTE:
If blue light leaks through any portion of
plenum and/or around mounting plate, unplug
power supply cord immediately and seal affected
areas and/or rotate ballast and repeat step #6 above.
9. UVC lamps contain a small amount of mercury, like a
typical fluorescent lamp. Check with your local waste
management authority for local disposal or recycling
requirements.
Never touch broken lamp or internal
contents of lamp. The lamp contains mercury.
NOTE:
In case of accidental exposure to internal contents
of lamp, wash hands and any other affected skin area
with a mild detergent. Remove affected clothing imme-
diately. If skin surface is pierced, seek medical attention
immediately.
