Do not exceed 60 Hz or go below 30 Hz. Exceeding 60 Hz will draw more horsepower from the motor than it was designed
for. Running at lower than 30 Hz may not supply enough starting torque to the mixer unit.

prop er ro tation.
7. Check full load current with amp probe and compare it with the name plate rat ing. On three phase mixers, check all three

MIXER MAINTENANCE:
Before handling these mixers and controls, always dis con nect the
power first. Do not smoke or use sparkable electrical devices or
flames in a septic (gaseous) or possible septic sump.
The maintenance schedule will vary with operating and environmental con-
di tions. It will also vary with the specific type of control supplied. The list
herein is a guide only.
1. Exercise breaker through one cy cle. Be careful not to over-exercise
as the breaker is not a switch ing device. Excessive operations tend to
affect the trip curve of the breaker.
2. Check relay for excessive humming. This can be accomplished by
turning mixer on and off in the Hand mode with the H-O-A switch.
3. Check mixer run light by running mixer in Hand mode. Check bulb(s)
in any other light(s).
4. With the power off, check con ti nu ity of all control fuses.
5. Check voltage at primary and sec ond ary of control transformer.
