Install the sub-base on a concrete foundation
CAUTION:
You must earth (ground) all electrical equipment. This applies to the pump equipment, the driver, and any
monitoring equipment. Test the earth (ground) lead to verify that it is connected correctly.
1. Remove water and debris from the anchor bolt holes and sleeves prior to grouting.
2. For sleeve-type bolts, fill the sleeves with packing or rags to prevent grout from entering.
3. Carefully lower the sub-base onto the foundation bolts and hand-tighten the bolt nuts.
4. Use a machinist's level to level the sub-base or a machine surface of the discharge head using leveling
wedges.
In order to ensure an accurate reading, check that the surface being leveled is free from all
contaminants, such as dust.

Grout the sub-base
Non-shrink grout is recommended for this procedure.
1. Inspect the foundation for dust, dirt, oil, chips, and water.
2. Remove any contaminants.
Do not use oil-based cleaners since they do not bond well with grout. Refer to the instructions from
the grout manufacturer.
3. Build a dam around the foundation.
4. Thoroughly wet the foundation.
5. Pour grout to a minimum thickness of 0.375 in. (9.520 mm) between the sub-base and concrete
foundation, up to the level of the dam.
6. Remove any air bubbles from the grout as it is poured by either puddling, using a vibrator, or
pumping the grout into place.
7. Allow the grout to set at least 48 hours.
