Use With Combustibles And Mixtures; Vacuum Equipment Cleanliness - Agilent Technologies UHV-24 User Manual

Instructions for Use

Use with Combustibles and Mixtures

As with all Ionization gauges, this device is not intrinsically safe. Exercise
WARNING
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 Cleanliness

Cleanliness is vital when servicing any vacuum equipment.
Do not use silicone oil or silicone grease.
Use powder-free butyl or polycarbonate gloves to prevent skin oils from getting
CAUTION
on vacuum surfaces.
Do not clean any aluminum parts with Alconox®. Alconox is not compatible with
aluminum and will cause damage.
Normally, it is unnecessary to use vacuum grease.
NOTE
However, if it must be used, do not use silicone types, and use it sparingly.
Apiezon® L grease is recommended (Agilent Part Number 695400004).
