The pumping units feature two separate ON/OFF switches, one at
the diaphragm pump and another one at the VNC 2 controller. To
operate the pumping unit you must switch on both the pump and
the controller!
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.
+
Operation with silencer (accessory) at the outlet: Op-
erating the pump at a high inlet pressure or pumping
dusty gases for a long time may cause clogging of the
silencer. Check the silencer regularly and replace if
necessary.
• 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.
