Maintenance
a: Clean the screen in the cyclone regularly.
Open the clamp between the fan and the cyclone.
Raise the fan housing up. Using an air hose or
small brush remove any foreign material from
the screen. This material will then be discharged
through the rotary valve.
Note: Lock off electrical power before
raising the fan housing. Do not operate the
unit with the fan housing raised.
b: Clean or replace the filter sock(s) regularly.
Tap the filter lightly to remove the dust or material
allowing it to fall to the bottom. When the build up
of material is sufficient, remove the filter and clean
completely.
c: Check paddle adjustment in the Rotary Valve.
Paddles should just contact the wall of the rotary
valve. If there is a gap between them, loosen the
screws and slide the paddle outwards until it con-
tacts the wall. Retighten the screws.
If the paddles are too tight against the wall, the
rotary valve will take too much power to operate, or
may stop turning altogether.
If there is too much gap between the paddles, on
the SUC unit the air pressure used below to convey
the material will blow back into the cyclone. This
will cause reduced conveying capacity and possible
plugging in the transfer lines.
