cabinet.
2. Unplug the cabinet, and open the door.
3. Remove the UV lamp by rotating it 90 degrees and lifting it straight up
and out of its sockets.
4. Install new lamp by reversing the removal procedure.
Resetting a Circuit Breaker:
To reset any of the circuit breakers located on the top rear of cabinet, depress
the white button until it sets.
Setting the Speed Control
Adjustment of the speed control varies the volume of air drawn through the
liner while the unit is operating. Ideally, smoke released into the intake
prefilter should traverse the liner, and be drawn into the exhaust prefilter in
approximately 5 seconds or less.
Using a small screwdriver, adjust the speed control to give the required face
velocity. See Figure 6-4 to locate the speed control. The air velocity is
increased by turning the speed control counter clockwise and clockwise to
decrease velocity.
