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.
• Grout: Non-shrink grout is required.
1. Clean all the areas of the baseplate that will come into contact with the grout.
2. Build a dam around the foundation.
3. Thoroughly wet the foundation that will come into contact with the grout.
4. Pour grout into the baseplate up to top of the base rails.
To hold wedges or shims in place, allow the grout to flow around them.
Follow grout manufacturer's instructions for removing air pockets from grout during
pour.
5. Allow the grout to set.
The grout needs to set for at least 48 hours. Follow any additional instructions from the
grout manufacturer.
6. Tighten the foundation bolts.
Piping checklist
WARNING:
• The heating of water and other fluids causes volumetric expansion. The associated forces
can cause the failure of system components and the release of high-temperature fluids.
In order to prevent this, install properly sized and located pressure-relief valves. Failure
to follow these instructions can result in serious personal injury or death, or property
damage.
• Avoid serious personal injury and property damage. Make sure that the flange bolts are
adequately torqued.
• Never force piping to make a connection with a pump.
Check Explanation/comment Checked
Check that the suction and discharge pipes are
supported independently by use of pipe hangers near
the pump station.
This eliminates pipe strain on the pump
station.
Check that there is a strong, rigid support for the
suction and discharge lines.
As a rule, ordinary wire or band hangers are not
adequate to maintain proper alignment.
Check that the suction or discharge lines are not
forced into position.
Component failure will result if suction or
discharge lines are forced into position.
Check that fittings for absorbing expansion are
installed in the system when considerable
temperature changes are expected.
This helps to avoid strain on the pump.
Check that you have a foot valve of equal or greater
area than the pump suction piping when you use an
open system with a suction lift.
Prevent clogging by using a strainer at the
suction inlet next to the foot valve. Make sure
that the strainer has an area three times that of
the suction pipe with a mesh hole diameter of
no less than 0.25 in. (0.64 cm).
