between the fluorescent lamp and the diffuser.
Remove the UV lamp by grasping the plastic
endcap on the left end of the lamp. While
supporting the center of the lamp, push the endcap
towards the left.
3. Allow the right side of the lamp to drop out of its
socket, then pull the lamp straight down.
4. Make sure that the surface of the new lamp is clean
and free of dirt or fingerprints by cleaning its
surface with alcohol or glass cleaner.
5. Install the new lamp by reversing the above steps.
The service operations listed in the
rest of this chapter should only be
performed by a qualified certifier.
Speed Control Adjustment:
Adjusting the speed control will have
an effect on the air velocities and the
effectiveness of the clean bench. Only
a qualified certification technician, as
part of the recertification process,
should adjust the speed control.
1. Remove the prefilters as described on page 43.
2. Locate the speed control. It is to the left of the
blower on 3-foot and 4-foot models, and between
the blowers on the 6-foot model.
3. Using a medium-sized, straight blade screwdriver
turn the speed control screw clockwise to decrease
the blower speed as shown in Figure 6-2.
