4. Sequentially tighten the four exhaust filter sealing bolts located at each corner of the
exhaust filter tray until the exhaust filter gasket is compressed no more than 50%.
The exhaust filter sealing bolts should only be tightened enough to ensure a
proper seal of the exhaust HEPA filter. At maximum tightness, the exhaust
filter's gasket should be compressed to 50% of its original thickness. NEVER
tighten the bolts beyond this setting.
5. Install the blower chamber cover, uniformly tightening the screws on the cover until
the gasket has formed a proper seal.
6. Install damper bolt seal as described earlier in this section.
7. Install the front dress panel.
8. Plug in the cabinet and recertify it before use.
Motor/Blower Replacement
Caution: The cabinet must be properly decontaminated before servicing the
motor/blower.
The cabinet blower motor's bearings are sealed and require no lubrication.
DO NOT attempt to lubricate them.
To replace the Motor/Blower:
1. Unplug the cabinet.
2. Remove the front dress panel as shown in Figure 7-1.
3. Loosen all of the Phillips screws on the blower chamber cover. Remove all of the
screws except two screws on the top center of the panel. This will support the
panel.
4. Release the damper seal by pushing the outside edge of the seal towards the
bolt and inside the blower plenum cover, as shown in Figures 7-14 and 7-15.
5. Remove the last two screws. Gently rock the cover, slide it to the left or right,
and swing it out and away from the unit.
NOTE: During disassembly, the blower plenum cover can rest on the central sash
support, as shown in Figure 7-16, to allow for repositioning of the panel or your grip on
it.
6. Disconnect both motor connectors from the motor. The 5-pin power connector,
located closest to the blower, is released by pressing the locking ears on either
side of the connector. The 16-pin data connector, located furthest from the
blower, is released by pressing the single locking ear located on the inside center
surface of the connector body. The connectors are shown in Figure 7-23.
