fitted to the pump inlet. In such a case, use the special
suction pipe with the built-on strainer.
NOTE
Use the heater for best separation result.

Suction pipe (½”) with built-on strainer
NOTE
Do not connect the return outlet to a pressurized system
with the same or higher pressure than the pressure
switch set point (50 kPa). Otherwise the safety function
of the switch will be overridden, which implies that the
pump can operate without flow.
6. Connect the power cable to the mains. See
also information in chapter
10 Technical data
on page 69 .
NOTE
Be sure the mains fulfil the voltage requirement. The
frequency converter fitted in the control cabinet will
cut off the power at voltage spikes or at too high/low
voltage (±10%).
