control center to rotate down, resting on the safety straps. Disconnect electrical connectors on left side.
Disconnect electrical from right side. (Be sure to note the location of the supply and exhaust sensor wires
before disconnecting them from the main board). Remove control center by disconnecting safety straps
lifting the control center up and away from cabinet. Fold and pinch tubing to seal.
2. Remove the front decorative panel via top/front fasteners.
3. Remove window assembly (both frame and window, either being manual, sliding, or automatic) via the
upper and lower fasteners (Refer to BCD-16376). At this point, the sliding window assembly can be
removed.
4. Remove exhaust sensor shrouds.
5. Remove the diffuser screen and gasket around perimeter of workzone, if present.
6. Prepare decontamination equipment. Reference decontamination procedure and use the following chart
to calculate chemical requirements.
Note: The outlets in the work area are energized as long as the cabinet is plugged in and
switched on the front panel. Unplug the cabinet before decontamination equipment is
plugged into these outlets. The control centers electrical connectors may be re-attached
to utilize the cabinet's interior outlets and fan during the decontamination.
7. Set control center on its side resting on the left side of cabinet. Then plug in the 16-pin connector cable
from the cabinet to the control center. Reconnect power to the cabinet. The outlets and blower can then
be activated.
8. Seal front and top openings using plastic and tape.
BE SURE CABINET IS TOTALLY SEALED TO PREVENT ANY
LABORATORY EXPOSURE TO DECONTAMINATION GAS.
9.
Perform decontamination procedure.
Please consult with NuAire, Inc. about any unique contamination problems.
Normally, no preventive maintenance is required on the interior of the cabinet (i.e., the area behind the
access panel containing the HEPA filters and motor (blower assembly). All required adjustments in order
to maintain proper cabinet airflows are external to the cabinet interior. The motor is lubricated for life
and is thermally protected with automatic reset.
7.2 Fluorescent/LED Lamp Replacement
The two (T8) fluorescent bulbs or optional LED lamps are cool white and placed external to the cabinet to aid maintenance
and minimize heat build-up within the cabinet. The life rating of the bulb is 9,000 for fluorescent and 50,000 hours for LED
based on three-hour burning cycles.
To replace a lamp, it is necessary to remove the lamp assembly.
1. Switch cabinet light switch off.
2. Remove the screws at each upper side of the control center and allow the control center to rotate down, resting
on the safety straps.
3. The lamp is now directly exposed for replacement.
4. The lamp is removed by displacing the bulb to one side against the compressible bulb holder and lifting out the
lamp.
5. Reverse the procedure to reinstall the lamp assembly being careful not to pinch the safety straps, cable or tubing
during closure of the control center.
