7.2 Replacing Molecular Sieve
The molecular sieve in the Zero Air Generator requires periodic replacement.
Time for replacement can be determined by comparing the values of an air
sample taken from the
Test port to those of an air sample taken at the Out port
as described in Section 6.1 , Theory of Operation
(p. 4)
. Two bottles of pn 27450
are needed to fill the bottle when replacing the molecular sieve material as
described in the following steps and illustrations.
1. Loosen the three screws that attach the box lid as shown in step 1 of
Section
7.1 , Replacing Batteries
(p. 8)
, and remove the lid.
2. Unscrew the two 1/8-in Swagelok
®
nuts.
