Operation
WARNING
MOVING PARTS HAZARD
To reduce the risk of serious injury, including cuts, amputation of fingers by the agitator blades, and
splashing in the eyes or on the skin, always shut off the agitator (disconnect the air line from the
agitator) before you raise, check, or repair the agitator.
Startup
1. Make sure the needle valve (23) is closed.
2. Turn on the air supply, and connect the air line
coupler.
3. Using the needle valve (23) to adjust the agitator
speed, gradually increase the speed until you can
see through the inspection port movement in the
surface of the liquid, but do not increase the agita-
tor speed enough to create a vortex in the surface
of the liquid. If the surface begins to vortex,
decrease the agitator speed to prevent air entrain-
ment.
NOTE: Always maintain moderate agitator speed,
which is approximately 50 rpm of the agitator blades.
Excessive agitator speed may cause vibration, foam-
ing of fluid, and increased wear on parts. Always
agitate fluid thoroughly before supplying it to the dis-
pensing equipment. Continue agitating fluid while the
dispensing equipment is being supplied.
Shutdown
To stop the agitator, close off the air supply with the
needle valve (23), or disconnect the air line coupler.
CAUTION
Keep the agitator upright. Do not lay it on its side or
upside down, or liquid may flow down the shaft and
into the gear reducer area.
