Connecting the Regeneration Plumbing
The Regeneration Plumbing allows the copper catalyst and molecular sieve to
be regenerated as needed. The regeneration process takes 13 hours and may
be completed overnight. Refer to Figures 3-1, 3-3, and 3-8.
First, locate the tank of 4% hydrogen/inert gas mixture. Using the
AtmosPure Regeneration Tubing Kit, route the tubing from the 4% hydrogen
gas mixture pressure regulator to the valve inlet per Figures 3-1 and 3-8. The
4% hydrogen mixture provides the gas to restore the copper catalyst. Be sure
to orient the ferrules properly and install the tube insert into the flexible line
on both ends per Figure 3-3. Tighten the compression fittings on both ends
1-1/4 turns past finger tight.
Second, locate the vacuum pump and route the vacuum line from the vacuum
pump to the vacuum solenoid valve located on the back of the AtmosPure
Re-Gen Gas Purifier per Figure 3-1. The vacuum line connection tubing is
included in the Gas Purifier Regeneration Tubing Kit. Again, be sure to
orient the ferrules properly, install the tube inserts, and tighten the
compression fittings 1-1/4 turns past finger tight. An alternate view for
connection to the vacuum solenoid valve is provided in Figure 3-5. If one
shared vacuum pump will be used and shared between the controlled
atmosphere glove box and the Gas Purifier, then the AtmosPure C.A. COM
cable (6-pin) must be connected between the Gas Purifier and the back of the
glove box Auto Pressure Control (refer to Figures 3-1, 3-6, and 3-8). If
shared with the controlled atmosphere glove box (only with auto pressure
control), then plug the vacuum pump into the back of the glove box (refer to
Figure 3-6). If a dedicated vacuum pump will be used for the Gas Purifier,
plug the vacuum pump into the electrical outlet on the back of the AtmosPure
Re-Gen Gas Purifier (Figure 3-1).
Third, the vent valve is exhausted through the 10-25 CFH flow control valve
as viewed in Figure 3-1. The vent line must be exhausted to the outside or to
a fume hood. From the Regeneration Tubing Kit, install the exhaust line to
the flow control valve and route the tubing to the outside or to a fume hood.
Again, properly install the tubing per Figure 3-3.
