If sand is visible in the sight glass (85),
the sand separator has to be emptied. If
a new sand separator has been installed,
you should check the level at short inter-
vals at the beginning. Later on, define an
emptying frequency, which you can enter
on the maintenance chart on page 26.
7.2
Emptying the Sand Separator S1
The sand separator protects the piping
system against abrasion due to sand-
blasting. If no sand separator is installed
downstream of a sandblaster or if the
sand separator is not emptied regularly,
the silica sand will erode through the
pipe walls in the course of time.
1. Turn OFF the extraction system at the
power switch (5) and allow the suction
turbine to come to a halt.
2. Place the sand container on the floor
(87).
3. Open the flap (86) by pulling the catch
to the right (sand flows out)
4. When the container is completely
empty, press the flap upwards firmly
until the catch snaps into place.
5. Remove the container and dispose of
the sand according to local regulations.
