Observe the cartridges' flow direction from the bottom to the top.
Information
Install the gas purification system as follows:
1.
Cover the screw fittings (9, 13, fig. 5-11) with NPT 1/4" external threads with Teflon
tape. Wrap 5 to 6 layers of customary Teflon tape (width approx. 10 mm) tightly
around the conical thread with a clockwise movement.
2.
Screw the screw fitting (9) of the inlet side into the base plate (7) finger-tight.
3.
Screw the screw fitting (13) of the outlet side into the connecting nut finger-tight.
4.
Fasten both screw fittings with max. 1 to 1.5 rotations.
5.
Slide the O-rings (10), dimensions 28.24 mm x 2.62 mm, over cartridges A and
B (4).
6.
Slide the union nut (5) over cartridges A and B with the threaded side pointing
down.
7.
Insert the O-rings (6), dimensions 22.2 mm x 3 mm, into the bottoms of
cartridges A and B.
8.
Insert the O-rings (2), dimensions 20 mm x 2 mm, into the connecting nut (1) and
into the connector (11).
9.
Screw cartridge A, generally fitted with an O-ring (3), tightly into the connecting
nut (1).
10. Screw cartridge B, generally fitted with an O-ring (3), tightly into the connector (11).
11. Connect the inlet line (8) and the outlet line (12) with the screw fittings (9 and 13).
12. Establish a low gas flow through the supply line.
13. Tighten the union nut (5) of cartridge B via the thread of the base plate (7).
14. Tighten the union nut (5) of cartridge A via the thread of the connector (11).
The gas purification system is now ready for operation.
