2.3 Mounting instructions
Please proceed according to the following order:
2.3.1 Return pipe
has to be mounted in order to as-
sure that the end of the pipe
reaches beneath the oil level in the
tank. Insert the return pipe into the
adapter and fix it with the setscrew.
It is possible to additionally glue it
in place.
2.3.2 Suction pipe
has to be fitted as far from the re-
turn pipe as possible (see drawing
in ch. 1). Screw suction pipe into
the adapter and glue it in place.
If the suction pipe is too short add
an oil resistant hose using a pipe
clamp to connect it to the pipe.
