Cleanout Procedure if Flooded
1. Remove the inlet filter, exhaust silencer and ballast silencer.
2. With high pressure water, clean intake, exhaust and ballast areas.
3. Have an assistant slowly turn the input shaft as you clean the lobes
with water.
4. Run the blower at the lowest speed possible and continue to spray
water into the inlet of the machine until the discharge shows only
clean water.
5. With the blower running, spray a small amount of penetrating oil
into the intake and run until no liquid comes out the exhaust. DO
NOT SPRAY OIL INTO THE BLOWER WITH THE SILENCERS IN PLACE.
6. Disassemble and clean the manifold/4-way valve assembly. Allow
to dry then reassemble.
7. If the blower was flooded, it is highly probable the exhaust silencer
has material in it as well. Clean it out as best you can. Drain all
fluids from the silencer and allow it to dry.
8. When everything is clean and dry, reassemble the manifold and
silencers. Make sure flange bolts on the blower are tightened
evenly.
