Overpressure at the suction port connection
The unit will be damaged
►
The pressure at suction port IN must be in the range from -0.25 to +2
bar.
NOTICE
Severe contamination
The unit will be damaged
►
Do not prime directly at the bottom of the tank.
►
Do not prime in the sump.
►
Never prime without a built-in suction screen.
The greatest contamination is found on the bottom of the tank.
All impurities and other particles are deposited on the bottom of
the tank.
Use a negative pressure-resistant, flexible hose or a pipe for the suction-side
connection.
Make sure that the cross-section of the connected hoses/piping is at least as
large as the cross-section of the inlet/outlet port sizes.
The shape of the tank connection should be set up in such a way that it will
always be lower than the level of the oil in the tank.
