WARNING
Read this instruction manual before installation, using, or servicing this
equipment. If you have any doubts about how to use this equipment safely,
phone customer service at
1–303–652–4400 or 1–800–776–6543 .
These symbols are associated with the handling of poisons and acids.
Follow all local and state codes when working with caustic materials and
liquids.
This symbol is associated with high voltage hazards. Follow all local and
state codes when working with high voltage equipment.
This symbol is associated with handling of combustible materials. Follow
all local and state codes when working with flammable materials and
liquids.
These symbols are associated with situations that may cause equipment to
burst violently due to excessive pressures. Make sure systems are
depressurized before attempting to work on them.
WARNING
Do not use the gauge tube to measure the pressure of combustible gas
mixtures. The sensing element normally operates at only 125° C but it is
possible that momentary transients or controller malfunction can raise the
sensor above the ignition temperature of combustible mixtures which may
explode causing injury to personnel or equipment damage.
WARNING
Danger of injury to personnel and damage to equipment exists on all
vacuum systems that incorporate gas sources or involve processes capable
of pressurizing the system above the limits it can safely withstand.
For example, danger of explosion in a vacuum system exists during
backfilling from pressurized gas cylinders because many vacuum devices
such as ionization gauge tubes, glass windows, glass bell jars, etc., are not
designed to be pressurized.
