Filtromat – OF5 C
3
Connecting the OF5 C
3.1
Suction port connection
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.
Connection to the tank must be done in a manner so that it is always below the oil
level.
TIP
The medium may not be drawn in directly from the bottom of the tank
where deposited impurities or clogging may impair the function of the unit.
3.2
Pressure port connection
The nominal size of the pressure hose should be equal to that of the filter housing
port whenever possible. If a smaller hose size is used, the back pressure must
nevertheless be > 2 bar with a clean filter element.
Install the return line or return hose below the oil level to prevent air from entering
the fluid.
For back pressures of >1 bar (14.5 psi), a differential clogging indicator should be
installed.
