5.5 Sieve Bed Replacement
WARNING
Do not refill the snap-ring-style sieve beds. Special
tooling is required to remove and re-install the spring-
loaded top cap and snap-ring.
CAUTION
Do not expose molecular sieve (contents of bed) to air
for an extended period of time. Pro longed exposure
of molecular sieve to the moisture in room air results
in contamination and permanent damage to the sieve
material. Keep all openings to the sieve beds sealed.
NOTE
If replacement is necessary, you must replace both sieve
beds at the same time.
