It is the installer's responsibility to ensure that the automatic signals provided by the product are
always used in a safe manner. Carefully check manual operation of the system and the set point
programming before switching to automatic operation.
Where an equipment malfunction could cause a hazardous situation, always provide for fail-safe
operation. As an example, in an automatic backfill operation where a malfunction might cause high
internal pressures, provide an appropriate pressure relief device.

Warning − If used improperly, Mini−Convectron Gauges can supply
misleading pressure indications that can result in dangerous overpressure
conditions within the system.
Do not operate in an explosive atmosphere.
Do not operate the product in the presence of flammable gases or fumes.
Operation of any electrical instrument in such an environment constitutes a
definite safety hazard.
Do not use the product to measure the pressure of explosive or combustible
gases or gas mixtures. The sensor wire of the Mini−Convectron Gauge
normally operates at only 125 ˚C, but it is possible that Controller malfunction
can raise the sensor temperature above the ignition temperature of
combustible mixtures.
Danger of explosion or inadvertent venting to atmosphere exists on all vacuum
systems which incorporate gas sources or involve processes capable of
pressurizing the system above safe limits.
