Installation
When the reading value is... Then...
Negative The pump coupling half (X) is lower than the
driver coupling half (Y). Remove shims of a
thickness equal to half of the indicator reading
value under each driver foot.
Positive The pump coupling half (X) is higher than the
driver coupling half (Y). Add shims of a thickness
equal to half of the indicator reading value to each
driver foot.
NOTICE:
4. Repeat the previous steps until the permitted reading value is achieved.
Perform parallel alignment for a horizontal correction
A unit is in parallel alignment when the parallel indicator (P) does not vary by more than 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.
Perform complete alignment for a vertical correction
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.

Grout the baseplate
Required equipment:
• Cleaners: Do not use an oil-based cleaner because the grout will not bond to it. See the
instructions provided by the grout manufacturer.
