Door Alignment
Pass-through chambers being installed in a cleanroom wall must be properly aligned to ensure proper operation of the interlock
mechanism.
1.
In a properly aligned pass-through chamber, the self-closing fire-
rated door shuts and latches completely without assistance and the
LiftLatch is centered in the corresponding catch (See
Figure 9
). To
align the chamber, one corner may need to be shimmed before
tightening the mounting brackets to the wall.
2.
Large chambers may include support legs with leveling feet. The
feet adjacent to the cleanroom wall should be adjusted to support
the chamber once the “clean” side door has been properly aligned.
3.
Repeat this procedure for the opposite (i.e., “dirty”) door. Raise or
lower the chamber corners until the door latch engages the center
of the catch. Then adjust the support frame leveling feet to retain
this alignment.
4.
Pass-through chambers deeper than 24” require support brackets. If
your installation includes support brackets, fasten these to the wall
underneath the chamber to achieve correct door alignment. The pass-
through chamber should rest on top of the support bracket without the need for additional fasteners (See
Figure 1:
bottom
).
NOTE
Pass-through doors can be removed for sterilization by lifting upwards at the hinges.
