WARNING
Install suitable devices that will limit the pressure from external gas
sources to the level that the vacuum system can safely withstand. In
addition, install suitable pressure relief valves or rupture discs that will
release pressure at a level considerably below that pressure which the
system can safely withstand.
Suppliers of pressure relief valves and pressure relief discs are listed in
Thomas Register under “Valves, Relief” and “Discs, Rupture.”
Confirm that these safety devices are properly installed before installing
the Convectron Gauge. In addition, check that
1. The proper gas cylinders are installed,
2. Gas cylinder valve positions are correct on manual systems, and
3. The automation is correct on automated systems.
WARNING
All conductors in, on or around a vacuum system that are exposed to
potential high voltage electrical discharges must either be shielded to
prevent human contact, or be connected to earth ground for safe operation.
When high voltage is present in any vacuum system, a life threatening
electrical shock hazard may exist unless all exposed conductors are
maintained at earth ground. The power cord of this product should be
connected only to a properly grounded outlet. However, grounding this
product does not guarantee that other components of the vacuum system
are maintained at earth ground.
Be aware that an electrical discharge through a gas may couple dangerous
high voltage directly to an ungrounded conductor almost as effectively as
would a copper wire connection. A person may be seriously injured or
even killed by merely touching an exposed ungrounded conductor at high
potential. This hazard is not peculiar to this product.
WARNING
Grounding, though simple, is very important! Please be certain that the
ground circuits are correctly utilized, both on your ion gauge power
supplies and on your vacuum chambers, regardless of their manufacturer,
for this phenomenon is not peculiar to Granville-Phillips equipment. Refer
to
Safety Instructions and Chapter 4, for additional information. If you
have questions, or wish additional labels or literature, please contact one
of our service personnel.
