A.
Beginning with the frame members labeled “1,” insert each horizontal frame member into the appropriate
opening of the corresponding upright frame support. As you position each horizontal member, fasten it loosely in
place with a white plastic push-in fastener (pre-drilled holes are located on the inside of the upright support). Do
not insert these fasteners completely until you have all horizontal supports correctly in position.
B.
When the frame members have been completely attached, square the structure to ensure that ceiling modules
will slide easily into place. To do this, measure the two diagonals (corner-to-corner distances). If they are not
equal, adjust the frame (by pushing on the appropriate corner) until they are.
C.
Two horizontal frame members provide the top and bottom support for the viewing window (see location in Fig.
1). These pieces attach to pre-drilled holes on the uprights on either side of the window. Make sure that the
mounting flange on each support bar attaches outside the window opening, so that the bars leave a 36”H
opening.
D.
Once the frame is complete, you will install the ceiling “T” joists: Before beginning ceiling installation, make sure
that you identify the ceiling perimeter members; these are pre-drilled for fastening to the cleanroom uprights.
Refer to system drawings to determine precise location (all members are labeled prior to shipping). The long “T”
joists span dimension of the cleanroom parallel to the entry door, and the short “T” joists slide in place to
complete the 2 x 4 ceiling grid (see page 17). Position the joists on top of the frame, as shown, and loosely
fasten the end of each joist in position with two SS #12 x ¾ hex screws. Do NOT tighten the hex screws until all
joists are in place and the room is square
E.
Control Panel Installation:
The Control Panel mounts to pre-drilled holes on the side of the upright next to the
main access door. Remove the front panel of the Control Panel, align the drilled holes inside to those on the
frame, and secure using sheet metal screws. Replace the front panel.
F.
Magnehelic Gauges and Control Panel Cable:
Each Magnehelic Gauge has a bulkhead fitting on top of the
Control Panel that connects to 0.25” poly tubing, which provides the reference pressure for the Anteroom and the
Buffer Room. Two shorter lengths of tubing are pre-plumbed to obtain the reference ambient pressure from two
fittings on the front of the Control Panel. The longer tubes, along with the yellow Control Panel power cable, pass
through the hole pre-drilled in the side of the steel frame upright and exit through the hole at the top. Make sure
the power cable is securely attached to the connector on top of the Control Panel. The other end of this cable will
attach to the Power Distribution Module on the ceiling, and the two poly tubes will attach to bulkhead fittings in
the Anteroom and Buffer Room ceiling panels (see Step Two). Mark the tubes to keep this reference clear: the
tube attached to the top gauge connects to the Buffer Room, and the tube attached to the bottom gauge
connects to the Anteroom. Ensure that these gauges are appropriately labeled.
