seldom necessary to engage the power
source for more than one second to
determine motor rotation.
Note the direction of motor rotation. If
the motor rotates counter clockwise as
viewed from the top, the rotation is to
correct and installation may proceed. If
the motor rotates clockwise as viewed
from the top, reverse any two of the
three power leads and motor rotation will
be reversed.
CAUTION
Operation of the pump in a clockwise (as
viewed from the top) direction will cause
the line shaft couplings to unthread,
causing serious damage to the pump.
D. Impeller adjustment is required to
achieve the preferred running position of
the impeller within the pump bowl. Also,
the impeller must not nib on the bowl
seat.
1. Determine the correct impeller
position from the Technical Data
page found in the drawing section of
this manual.
2. Thread the adjusting nut upwards
toward the driver half coupling until
the correct amount of gap “A” is
reached (refer to the above
illustration).
3. Adjust to the position that bolt holes
line up and insert coupling bolts.
Torque to the values as shown the
coupling dimension and technical
data page in the drawing section of
this manual. Install the set screw in
the pump coupling hub and secure.
4. Install protective guards.
WARNING
Make sure the protective guard is in
place on the discharge head before
operating the pump.
NOTE
Extremely long pumps (deep settings)
may require additional nut adjustment to
accommodate line shaft stretch. Extra
adjustment is not generally required for
pumps less than 150 feet in length. For
pumps over 150 feet long, consult the
factory for instructions.
E. Refer to the driver manual to assure that
all lubrication instructions have been
followed completely.
F. Refer to the driver manual to assure that
all safety procedures are completely
understood and implemented prior to
operation.
CAUTION
Grease lubricated drivers are shipped
pre-lubricated. Oil lubricated drivers and
right angle gears are shipped dry and
require an initial fill of the manufacturer's
recommended lubricant prior to start-up.
See driver manufacture’s manual for
lubrication specifications. Initial start-up
lubricants are not supplied by the
manufacturer.
