The pump achieves its pumping speed, ultimate total vacuum and vapour pumping
rate only at operating temperature (after approx. 15 minutes).
☞
Prevent internal condensation, transfer of liquids or dust. The diaphragm and
valves will be damaged, if liquids are pumped in significant amounts.
☞ Let the pump run with gas ballast to reduce condensation of pumped substances
(water vapour, solvents, ....) in the pump.

Attention: Open the terminal only outside of explosive atmospheres and only by
suitably trained personnel.
➨ Unscrew the terminal cover from the pump motor.
➨ Push the switch inside the terminal.
➨ Screw the terminal cover correctly, screw tightening torque: 23 Nm.
Attention:
Absolutely check the motor capacitor for leaks and capacity if the motor pro-
tection has been activated.
Check the complete pump for leaks in the gas line (integral leak rate < 0.1 mbar
l / s)!
