Xylem AquaForce Variable Speed Package System - Manual (Page 15)

Guideline Explanation/comment
Make sure that the space around the pump package is
sufficient.
This facilitates ventilation, inspection, maintenance, and
service.
If you require lifting equipment such as a hoist or tackle,
make sure that there is enough space above the pump
package.
This makes it easier to properly use the lifting equipment
and safely remove and relocate the components to a safe
location.
Protect the unit from weather and water damage due to
rain, flooding, and freezing temperatures.
This is applicable if nothing else is specified.
Do not install and operate the equipment in closed
systems unless the system is constructed with properly-
sized safety and control devices.
Acceptable devices:
• Pressure relief valves
• Compression tanks
• Pressure controls
• Temperature controls
• Flow controls
If the system does not include these devices, consult the
engineer or architect in charge before you operate the
pump.
Take into consideration the occurrence of abnormal noise
and vibration.
The best pump location for noise and vibration
absorption is on a concrete floor with subsoil underneath.
Foundation requirements
WARNING:
Electrical shock hazard. An electrical conduit installed below the surface may require a
corrosion-resistant protective coating in order to prevent conduit corrosion and electrical
shock. Failure to follow these instructions can result in serious personal injury, death, or
property damage.
Requirements
• The foundation must be able to absorb any type of vibration and form a permanent,
rigid support for the unit.
• The foundation must weigh at least 2-1/2 times the weight of the pump unit.
• Provide a flat, substantial concrete foundation in order to prevent strain and distortion
when you tighten the foundation bolts.
• Sleeve-type and J-type foundation bolts are most commonly used. Both designs allow
movement for the final bolt adjustment.
• Tie the concrete pad in with the finished floor.
Level the base on a concrete foundation
1. Place the pump package on its concrete foundation.
2. Place 1.00 in./(25.40 mm) thick steel shims or wedges on both sides of each anchor
bolt in order to support the pump package.
Make sure you also place the shims or wedges midway between the bolts.
This also provides a means of leveling the base.
