Vacuum Equipment and Cleanliness
Cleanliness is vital when servicing the leak detector or any vacuum equipment. There are
some techniques that are more important in leak detector servicing than in general vacuum
work:
CAUTION
Do not use silicone oil or silicone grease.
Use powder-free butyl or polycarbonate gloves to
prevent skin oils from getting on vacuum surfaces.
Do not clean any aluminum parts with Alconox
®
.
Alconox is not compatible with aluminum and will
cause damage.
NOTE
Normally, it is unnecessary to use vacuum grease.
However, if it must be used, avoid silicone types, and
use it sparingly. Apiezon
®
L grease (Varian Vacuum
Technologies Part No. 695400004) is recommended.
