During operation
➨
Vent and dispose of
potentially dangerous gases or
vapors at the outlet of the pump appropriately.
+
Due to the high compression ratio, the pump might
generate overpressure at the outlet. Check pressure
compatibility with system components (e.g., exhaust
tubing or exhaust valve) at the outlet. Ensure that the
pump outlet is neither blocked nor restricted.
+
Maximum ambient temperature: 104 °F (40 °C)
Check the maximum temperatures, if installing the
pump in a cabinet or a housing. Make sure ventilation
is adequate, especially if the ambient temperature is
elevated.
• If the pump is installed at an altitude of more than 6500
ft (2000 m) above mean sea level, check compatibility
with applicable safety requirements, and adopt suit-
able measures. There is a risk of the motor overheat-
ing due to insufficient cooling.
• Check compatibility with the
maximally permitted
pressure at outlet and the maximum pressure dif-
ference between inlet and outlet ports.
• Check the
oil level of the rotary vane pump every time
before starting the pump, however at least once a week.
Check the oil level more frequently if high amounts of
gas or vapor are pumped.
• If pumping aggressive, corrosive or otherwise danger-
ous gases and vapors, take appropriate measures to
protect personnel, pump, and environment. Use ap-
