DANGER
Severe injury can result from opening clamps when piping is hot. Before loosening any
clamps, determine if the pipe is hot. If so, let it cool before attempting to perform repairs.
Failure to comply will result in severe personal injury or death.
B. If the recirculation system is not working:
1. Disengage (turn off) clutch and stop engine.
2. Remove clamp attaching recirculation valve.
3. Slide rubber seal back and remove valve assembly.
4. Check valve assembly, recirculation nozzle in discharge pipe, and recirculation
pipe going into tank. Clear any obstructions.
5. Replace valve assembly and slide seal back into place. Lubricate outside of
seal.
6. Replace
clamp.
C. Obstruction in pump can be indicated by a drop in pressure. If a drop in pressure is
accompanied by a frothy or whitish discharge stream, blockage is in the suction line
or sump area. To clear the pump:
1. Disengage (turn off) clutch and stop engine. Close suction shutoff valve if appli-
cable.
2. Loosen suction pipe clamps. If there is material in tank, stuff a rag into the suc-
tion piping.
3. Remove suction pipe clamp closest to pump.
4. Remove elbow and slowly open suction shutoff valve.
NOTE:
If no water comes out, the obstruction is in sump area.
5. Reach into pump and remove obstruction. If it is jammed, the pump suction
cover may have to be removed.
6. Reassemble, removing rag plugging the suction piping.
D. Obstruction in sump area, which is located at the bottom of the tank on the inside
where the suction pipe is attached. Three methods to remove an obstruction in the
sump area are as follows:
1. Clear the sump by backflushing through the discharge plumbing with the water
supply hose. This is the easiest method.
2. Remove the drain plug and run a long pole through the opening and into the
sump area. Remove the obstruction and replace the drain cap.
3. Use a pipe or pole through the loading hatch opening to dislodge the obstruc-
tion.
CAUTION
Do not turn the shaft backward with a pipe wrench. This will unscrew pump impeller from
pump shaft. Consequently, when clutch is engaged (turned on), the pump impeller will
screw onto pump shaft with a force great enough to break pump impeller. Failure to comply
could result in minor or moderate personal injury. Failure to comply could also result in
product or property damage.
