2.6

Door Alignment

Pass-through chambers being installed in a cleanroom wall must

be properly aligned to ensure proper operation of the latch and the

interlock mechanism.

Align the pass-through chamber so that the front door latches

are centered in the corresponding catch (see

Figure 11

). To

align the chamber, one corner may need to be shimmed

before bolting the mounting brackets to the wall.

Large chambers may include support frames 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.

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. If your installation includes support brackets, mount these to the chamber and the wall to

achieve correct door alignment (See

Figure 3

Section 2.2

above).

Protruding Exhaust Flange or Filter Housing

3.0

If the pass-through arrived with either an exhaust flange or an ULPA filter housing preinstalled, these features will need to be

detached from the pass-through prior to installation to allow the pass-through to fit through the wall cut-out.

Exhaust Flange

Figure 13:

ULPA Filter Housing

To remove the exhaust flange, unscrew the 8 domed cap nuts around the base of the flange and remove the flange (See

Figure 12

To remove the ULPA filter housing, unscrew the 4 domed cap nuts on either side of the housing and remove both the

ULPA filter and the housing (See

Figure 13

Reinstall these features once the pass-through installation has been completed. Installation is the reverse of disassembly.
