PREPARATION FOR START-UP
CHECK ROTATION
$
CAUTION
Serious damage may result if mixer is run in the
wrong rotation.
1. Lock out power to driver.
p
! WARNING
Lock out driver power to prevent accidental start-up
and physical injury.
2. Make sure coupling hubs are securely fastened to shafts.
NOTE: Mixer is shipped with coupling spacer
removed.
3. Unlock driver power.
4. Make sure everyone is clear. Jog driver just long
enough to determine direction of rotation. Rotation
must correspond to arrow on bearing housing.
5. Lock out power to driver.
CHECK ROTOR AXIAL
CLEARANCE
The mixer efficiency is maintained when the proper rotor
clearance is set. The rotor has been centered in the casing
at the factory but could change due to piping attachment.
See
Preventive Maintenance section for rotor adjustment
procedure.
COUPLE MIXER AND DRIVER
p
! WARNING
Lock out driver power to prevent accidental rotation
and physical injury.
1. Install and lubricate coupling per manufacturer’s
instructions.
2. Install coupling guard (Fig. 19).
p
! WARNING
Never operate a mixer without a correctly installed
coupling guard. Personal injury will occur if mixer is
run without coupling guard.
