DO NOT OPERATE IN AN EXPLOSIVE ENVIRONMENT
To avoid explosion, do not operate this product in an explosive
environment unless it has been specifically certified for such
operation.
USE PROPER FITTINGS AND TIGHTENING PROCEDURES
All instrument fittings must be consistent with instrument
specifications, and compatible with the intended use of the
instrument. Assemble and tighten fittings according to
manufacturer’s directions.
CHECK FOR LEAK-TIGHT FITTINGS
Carefully check all vacuum component connections to the instrument
to ensure leak-tight installation.
OPERATE AT SAFE INLET PRESSURES
Never operate at pressures higher than the rated maximum pressure
(refer to the product specifications for the maximum allowable
pressure).
INSTALL A SUITABLE BURST DISC
When operating from a pressurized gas source, install a suitable burst
disc in the vacuum system to prevent system explosion should the
system pressure rise.
KEEP THE UNIT FREE OF CONTAMINANTS
Do not allow contaminants to enter the unit before or during use.
Contamination such as dust, dirt, lint, glass chips, and metal chips
may permanently damage the unit or contaminate the process.
ALLOW THE UNIT TO WARM UP
If the unit is used to control dangerous gases, they should not be
applied before the unit has completely warmed up. Use a positive
shutoff valve to ensure that no erroneous flow can occur during
warm up.
