Use with Combustibles and Mixtures
WARNING
As with all ionization gauges, this device is not intrinsically
safe. Exercise extreme care when using this vacuum gauge
while pumping or backfilling a system or in any other system
condition which contains combustible gases or mixtures. The
filament, the end of a hot filament ion gauge and the high
voltage discharge of a cold cathode gauge can be ignition
sources.
When such a gas or mixture is present, do not turn on any such
vacuum gauge.
Failure to follow this instruction could result in serious injury to
personnel and damage to equipment.
Vacuum Equipment and Cleanliness
Cleanliness is vital when servicing any vacuum equipment.
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, do not use silicone types, and
use it sparingly. Apiezon
®
L grease is recommended
(Varian Part Number 695400004).
