Connecting the suction port
NOTICE
Overpressure at the suction port connection
The unit is damaged
►
The pressure at suction port IN must be in the range from -0.25 to +2 bar.
NOTICE
Contamination too high

The greatest contamination is found on the bottom of the tank. All
impurities and other particles are deposited on the bottom of the tank.
Make the suction-side connection with a flexible hose that is resistant to negative
pressure or with pipelines. The nominal size of the connecting lines must be at least
as large as the cross-section of the unit in order to prevent excessively high
pressure loss.
The suction port must be arranged so that it is always below the oil level.

To avoid a concentration of air in the medium, the return-flow line must always be
located below the oil level.
