12 TROUBLESHOOTING

12.1 Water Entrainment

Issue: Excessive discharge of water in the exhaust may be due to the

following:

Fix:

 Incorrect rotation (correct rotation is counter-clockwise, when

viewed form the drive end).

 Incorrect size cone spray or auxiliary nozzles and incorrect spray

pattern (i.e. flat spray at 7 o’clock position viewed from the inlet and

parallel to blades and cone spray to be centered at wheel).

 Inlet spray should just miss inlet perimeter as it passes into the

scroll.

 Disturbances at inlet, such as elbows or branch entries, causing

unbalanced airflow or dust loading (see Section 2.3).

 Bent blade tips and/or obstructions in impeller such as rags,

collected material buildup, etc.

• Pluggage of drains.

 Incorrect outlet piece location. The bottom of the outlet piece should

never be above the bottom of the RotoClone® scroll. Any gasketing

that has squeezed out should be removed.

 Improper gasketing of water cone, or damage/wear of the water

cone.

• Incorrect water pressure.
