Installation
NOTICE:The specified permitted reading values are valid only at operating temperature.
For cold settings, other values are permitted. You must use the correct tolerances. Failure
to do so can result in misalignment and reduced pump reliability.
Perform parallel alignment for a horizontal correction
A unit is in parallel alignment when the parallel indicator (P) does not vary by more than
0.002 in. (0.05 mm) as measured at four points 90° apart at the operating temperature.
1. Set the parallel alignment indicator (P) to zero on the left side of the driver coupling half (Y),
90° from the top-center position (9 o’clock).
2. Rotate the indicator through the top-center position to the right side, 180° from the start
position (3 o’clock).
3. Record the indicator reading.
When the reading value is... Then...
Negative The driver coupling half (Y) is to the left of
the pump coupling half (X).
Positive The driver coupling half (Y) is to the right of
the pump coupling half (X).
4. Slide the driver carefully in the appropriate direction.
NOTICE:Make sure to slide the driver evenly. Failure to do so can negatively affect
horizontal angular correction.

5. Repeat the previous steps until the permitted reading value is achieved.
NOTICE:The specified permitted reading values are valid only at operating temperature.
For cold settings, other values are permitted. You must use the correct tolerances. Failure
to do so can result in misalignment and reduced pump reliability.
Perform complete alignment for a vertical correction
A unit is in complete alignment when both the angular indicator (A) and the parallel indicator (P)
do not vary by more than 0.002 in. (0.05 mm) as measured at four points 90° apart.
1. Set the angular and parallel dial indicators to zero at the top-center position (12 o’clock) of
the driver coupling half (Y).
2. Rotate the indicators to the bottom-center position (6 o’clock).
3. Record the indicator readings.
4. Make corrections according to the separate instructions for angular and parallel alignment
until you obtain the permitted reading values.
