Warning
Explosive Gases
Do not use the Model PDR 2000 Dual Capacitance Diaphragm
Gauge Controller to measure the pressure of combustible gas
mixtures. The gauge normally operates at low temperatures, but it
is possible that momentary transients or controller malfunction may
cause ignition of combustible mixtures, which then might explode
and cause damage to equipment and injury to personnel.
Warning
Limitation on Use of Compression Mounts
Do not use a compression mount (quick-connect) for attaching the
gauge tube to the vacuum system in applications that may develop
positive pressures. Positive pressures may cause the tube to be blown
out of a compression fitting and damage equipment and injure
personnel.
Warning
Chemicals
Many organic cleaning solvents, such as acetone, produce fumes
that are toxic or flammable. Use such solvents only in areas that are
well ventilated to the outdoors and away from electronic equipment,
open flames, or other
potential ignition sources.
