7.1 Selection of mounting position
The SWK-2000 should be installed in an easily accessible location in the suction line of the fuel
system between fuel tank and fuel pump. Any combination of inlet and outlet ports can be used.
A shut off valve is always recommended in between the tank and the filter. If the
filter is postioned below the tank (position 2), there is always a slight pressure on the
fuel inlet of the filter, which can facilitate the priming of the filter.
When the filter is positioned higher than the tank (position 1), we recommend the
hand priming pump of W. Lösing Filtertechnik e. K. (s. chap. 11) to be mounted in the
fuel line.
Please note that the filters have to be installed on an even surface..
When installing the filter sufficient space of at least 60 mm above the filter lid must be
allowed.
Below the filter sufficient space must be left to either place a suitable container for
draining bowl or to attach a hose directly to the drain valve to allow drainage of water
out of the filter.
7.2 Filter installation
Install the filter with the back against a sufficiently stable and flat surface. Depending on the filter
option the SWK-2000 offers two or four holes (s. chap. 4.1) for mounting the filter: The diameter of
the mounting holes can be found in the technical data (s. chap. 4.2).
Subsequently, the fuel ports are connected. There are ports for inlet and outleton either side of the
filter housing. Matching fittings and adapters are a neccessity please consult section 5.7 for port size.
