CHECK FOR LEAK-TIGHT FITTINGS
Carefully check all vacuum component connections 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.
