Perform Parallel Alignment For A Horizontal Correction; Perform Complete Alignment For A Vertical Correction - ITT 3610 i-FRAME Manual

4. 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 set-
tings, other values are permitted. The correct tolerances must be used. Failure to do so can
result in misalignment. Contact ITT for further information.

4.4.8 Perform parallel alignment for a horizontal correction

Refer to the alignment table in "Permitted indicator values for alignment checks" (see Table of Contents
for location of table) for the proper cold alignment value based on the motordriver temperature rise and
the pump operating temperature.
A unit is in parallel alignment when the parallel indicator (P) does not vary by more than 0.05 mm |
0.002 in. 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.

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.

4.4.9 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 0.05 mm | 0.002 in. as measured at four points 90° apart.
