You may need to sandblast the surfaces of a baseplate that come in contact with grout, and then coat those surfaces with a primer that is grout-compatible. Make sure to remove all equipment before sandblasting.
3. Make sure that all machined surfaces are free from burrs, rust, paint, or any other type of contamination. If necessary, use a honing stone to remove burrs.

Prepare the foundation for mounting

1. Chip the top of the foundation to a minimum of 1.0 in. (25.0 mm) in order to remove porous or low-strength concrete. If you use a pneumatic hammer, make sure that it does not contaminate the surface with oil or other moisture.
NOTICE:
Do not chip the foundation using heavy tools such as jackhammers. This can damage the structural integrity of the foundation.
2. Remove water or debris from the foundation bolt holes or sleeves.
3. If the baseplate uses sleeve-type bolts, then fill the sleeves with a non-binding, moldable material. Seal the sleeves in order to prevent the grout from entering.
4. Coat the exposed portion of the anchor bolts with a non-bonding compound such as paste wax in order to prevent the grout from adhering to the anchor bolts. Do not use oils or liquid wax.
5. If recommended by the grout manufacturer, coat the foundation surface with a compatible primer.
Installation

Install the baseplate using jackscrews

Tools required:
• Anti-seize compound
• Jackscrews
• Bar stock
• Two machinist's levels
This procedure is applicable to the feature-fabricated steel baseplate and the advantage base baseplate.
1. Apply an anti-seize compound on the jackscrews. The compound makes it easier to remove the screws after you grout.
2. Lower the baseplate carefully onto the foundation bolts and perform these steps: a) Cut the plates from the bar stock and chamfer the edges of the plates in order to reduce
stress concentrations. b) Put the plates between the jackscrews and the foundation surface. c) Use the four jackscrews in the corners in order to raise the baseplate above the
foundation.
Make sure that the distance between the baseplate and the foundation surface is
between 0.75 in. (19 mm) and 1.50 in. (38 mm).

3. Level the driver mounting pads:
NOTICE:
Remove all dirt from the mounting pads in order to make sure that you achieve the correct leveling. Failure to do so can result in equipment damage or decreased performance.
a) Put one machinist's level lengthwise on one of the two pads. b) Put the other machinist's level across the ends of the two pads. c) Level the pads by adjusting the four jackscrews in the corners.
Make sure that the machinist's level readings are as close to zero as possible, both
lengthwise and across.
4. Turn the center jackscrews down so that they rest on their plates on the foundation surface.
5. Level the pump mounting pads:
NOTICE:
Remove all dirt from the mounting pads in order to make sure that you achieve the correct leveling. Failure to do so can result in equipment damage or decreased performance.
a) Put one machinist's level lengthwise on one of the two pads. b) Put the other level across the center of the two pads. c) Level the pads by adjusting the four jackscrews in the corners.
Make sure that the machinist's level readings are as close to zero as possible, both
lengthwise and across.
6. Hand-tighten the nuts for the foundation bolts.
7. Check that the driver's mounting pads are level and adjust the jackscrews and the foundation bolts if necessary. The correct level measurement is a maximum of 0.002 in./ft (0.0167 mm/m).
The maximum variation from one side of the baseplate to the other is 0.015 in. (0.38 mm).

Install the pump, driver, and coupling

1. Mount and fasten the pump on the baseplate. Use applicable bolts.
2. Mount the driver on the baseplate. Use applicable bolts and hand tighten.
3. Install the coupling. See the installation instructions from the coupling manufacturer.

Pump-to-driver alignment

Precautions
WARNING:
• Follow shaft alignment procedures in order to prevent catastrophic failure of drive components or unintended contact of rotating parts. Follow the coupling installation and operation procedures from the coupling manufacturer.
• Always disconnect and lock out power to the driver before you perform any installation or maintenance tasks. Failure to disconnect and lock out driver power will result in serious physical injury.
NOTICE:
Proper alignment is the responsibility of the installer and the user of the unit. Check the alignment of frame-mounted units before you operate the unit. Failure to do so can result in equipment damage or decreased performance.
Alignment methods
Three common alignment methods are used:
• Dial indicator
• Reverse dial indicator
• Laser
Follow the instructions from the equipment manufacturer when you use the reverse dial indicator or laser methods. Detailed instructions for using the dial indicator method are contained in this chapter.

Alignment checks

When to perform alignment checks
You must perform alignment checks under these circumstances:
• The process temperature changes.
• The piping changes.
• The pump has been serviced.
Types of alignment checks
Type of check When it is used
Initial alignment (cold alignment) Prior to operation when the pump and the driver are at ambient check temperature.
Final alignment (hot alignment) After operation when the pump and the driver are at operating check temperature.
Initial alignment (cold alignment) checks
When Why
Before you grout the baseplate This ensures that alignment can be accomplished. After you grout the baseplate This ensures that no changes have occurred during the grouting
After you connect the piping This ensures that pipe strains have not altered the alignment.

Permitted indicator values for alignment checks

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.
IMPORTANT
• For electric motors, the motor shaft initial (cold) parallel vertical alignment setting should be 0.002 to 0.004 in. (0.05 to 0.10 mm) lower than the pump shaft.
• For other drivers such as turbines and engines, follow the driver manufacturer's recommendations.
When dial indicators are used to check the final alignment, the pump and drive unit are correctly aligned when these conditions are true:
• The total indicator runout is a maximum of 0.002 in. (0.05 mm) at operating temperature.
• The tolerance of the indicator is 0.0005 in./in. (0.0127 mm/mm) of indicator separation at operating temperature.

Attach the dial indicators for alignment

You must have two dial indicators in order to complete this procedure.
1. Attach two dial indicators on the pump coupling half (X): a) Attach one indicator (P) so that the indicator rod comes into contact with the perimeter
of the driver coupling half (Y). This indicator is used to measure parallel misalignment.
b) Attach the other indicator (A) so that the indicator rod comes into contact with the inner
end of the driver coupling half. This indicator is used to measure angular misalignment.
