Intended use
☞ Ensure that the individual components are only connected, combined and oper-
ated according to their design, or with OEM parts, and as indicated in the instruc-
tions for use.
☞ Comply with notes on correct vacuum and electrical connections, see section
„Description“, pg. 14.
☞ The equipment is designed for ambient and gas temperatures at continuous
operation between +10°C and +40°C and up to 80°C for short periods at the
vacuum connection. Check the maximum temperatures, especially if installing
the equipment in a cabinet or a housing and make sure ventilation is adequate.
Ensure that the maximum permitted gas temperature at the pressure transducer
(see „Technical data“, pg. 12) is not exceeded.
Use the equipment and all system parts for the intended use only, i.e. for control
and measurement of vacuum in vessels designed for that purpose.
Connecting the controller
☞ Do not permit any uncontrolled pressurizing (e.g., make sure that pipelines
cannot become blocked) to avoid a risk of bursting!
☞ Check the maximum ambient and gas temperatures (see „Technical data“, pg.
12, especially if installing the equipment in a cabinet or a housing or in case of
elevated ambient temperatures.
• Comply with max. permitted pressure at the pressure transducer, see section
„Technical data“, pg. 12.
• Connect hoses gas tight at the vacuum connection of the pressure transducer.
