8.3.4 Sieve Beds
Do not expose molecular sieve (contents of bed) to air for
an extended period of time. Prolonged 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.
If replacement is necessary, you must replace both sieve
beds at the same time.
