Always maintain moderate agitator speed.
Excessive agitator speed may cause vibration,
foaming of fluid, and increased wear on parts.
Always agitate fluid thoroughly before supplying it
to the dispensing equipment. Continue agitating
fluid while the dispensing equipment is being
supplied.
Fill the fluid supply container to about 3 or 4 inches
(75 to 100 mm) above the agitator blades to avoid

1. Turn the air regulator knob (R) counterclockwise
to start at zero air pressure.
2. Open the air shutoff valve (SV).
3. Use the air regulator knob (R) to adjust the
before
agitator speed. Look through the inspection port
and gradually increase the speed until you can
see movement in the surface of the liquid. Do
not increase the agitator speed so much that a
vortex forms in the surface of the liquid. If the
surface begins to vortex, decrease the agitator
speed to prevent air entrainment.
Always maintain moderate agitator speed, which
is approximately 50 rpm of the agitator blades.
Excessive agitator speed may cause vibration,
foaming of fluid, and increased wear on parts.
Always agitate fluid thoroughly before supplying it
to the dispensing equipment. Continue agitating
fluid while the dispensing equipment is being
supplied.
