Final Alignment
Final alignment cannot be accomplished until
the pump has been operated initially for a
sufficient length of time to attain operating
temperature. When normal operating
temperature has been attained, secure the
pump to re-check alignment and compensate
for temperature accordingly. See Alignment
Section.
WARNING: Rotating Components
Hazard
Do not operate pump without all guards in place.
Failure to follow these instructions could result in
serious personal injury or death and property
damage.
WARNING: Coupling Failure
Do not operate pump with coupling out of
alignment. Ensure final coupling alignment is
within the values stated above or according to the
coupling manufacturer’s instructions. Coupling,
pump, or driver failure may occur.
Failure to follow these instructions could result in
serious personal injury or death and property
damage.
OPTIONAL Alignment Procedure
If desired, the pump and motor feet can be
doweled to the base after final alignment is
complete. This should not be done until the
unit has been run for a sufficient length of
time and alignment is within the tolerance.
See Doweling Section.
CAUTION: Extreme Temperature and/or
Flying Debris Hazard
Eye protection and gloves required. Failure to
follow these instructions could result in property
damage and/or moderate personal injury.
NOTE: Pump may have been doweled to
base at factory.
