Transfer Chamber Pressure Gauge Kit No. 5238100

Operation

This Transfer Chamber Pressure Gauge Kit can only be added to the Precise HEPA-Filtered
Glove Box and XPert Weigh Box. The Transfer Chamber Pressure Gauge Kit monitors
pressure/vacuum from 0 to -29 inches of mercury and includes the vacuum gauge, hose,
mounting bracket, fittings, and hardware. The installation requires drilling a 0.562" diameter
hole in the back of the transfer chamber; if needed a 0.562" hole saw (#5250603) and arbor
(#5250500) may be ordered from Labconco. Follow the installation procedure and pictorial that
follow to properly install the Transfer Chamber Pressure Gauge.

Installation Procedure

1. Refer to the pictorial and loosen the screws holding the electrical cover, slip gauge and

bracket under the screws and retighten.

2. Using two adjustable wrenches, tighten the female tube connector to the rear of the

pressure gauge using Teflon tape to prevent leaks.

3. Place tubing inserts in both ends of the 3/8 OD x 3/16 ID polyvinyl tubing with

compression nut and ferrules per the Compression Fitting Installation View. Insert one
end on to the back of the pressure gauge. Using two adjustable wrenches, tighten the
compression nut 1-1/4 turns with the tubing, ferrules and insert inside the female
connector.

4. Route the other end of the tubing through the 1/2" hole on the right side of the rear back

panel of the glove box.

5. Per view E-E, drill a 0.562" diameter hole in the center of the boss located on the rear of

the transfer chamber. If needed, a 0.562" hole saw (#5250603) and arbor (#5250500) may
be ordered from Labconco.

6. Follow Section C-C and Compression Fitting Installation View to mount the bulkhead

fitting, O-rings, and the stainless steel nut from the kit. The stainless steel nut and second
O-ring are located inside the transfer chamber. By using two adjustable wrenches, tighten
the bulkhead fitting to the transfer chamber.

7. Connect the other end of the polyvinyl tubing to the bulkhead fitting. By using two

adjustable wrenches, tighten the compression nut on the bulkhead fitting 1-1/4 turns with
the tubing, ferrules, and insert placed inside the fitting.

8. Installation is now complete and the pressure gauge kit should hold vacuum if properly
