Entegris, Inc | Installation and Use Manual
REPLACING THE O-RINGS
—
1. Make sure the O-rings are not tilted or distorted.
2. If the O-ring is significantly tilted or distorted from
the groove do not use it due to risk of chemical
leakage.
3. Follow the steps in this manual to remove and
install the filter again.
4. If re-installing the filter does not fix the O-ring
position, follow the steps to replace the O-ring.
NOTE: For replacement O-ring ordering
information refer to page 2.
REMOVING THE O-RINGS
a) Grasp the far end of the connector and the
O-ring with your thumb and forefinger.
CAUTION: Wipe away any chemical following
safety guidelines before replacing the O-rings.
b) Pull your thumb and forefinger nearside and push
the O-ring out. Grasp the protruding part of the
O-ring with your other hand, and push it down
from above to remove it from the groove.
CAUTION: Do not use any sharp tool such as
scissors, tweezers, or knife to remove O-rings
as it may damage the connectors or O-rings.
ATTACHING THE O-RINGS
c) Insert the O-ring into the O-ring groove on
the connector first.
d) Then slowly push the entire O-ring along
the groove.
e) After installation, make sure the O-ring is not
twisted or tilted and is seated properly in the
groove. Also ensure it is not contaminated
with dust.
CAUTION: Make sure that O-rings are properly
attached. Improper installation may cause
chemical leakage.
