GuidelineExplanation/comment
Make sure that the space around the pump package is
sufficient.
If you require lifting equipment such as a hoist or tackle,
make sure that there is enough space above the pump
package.
Protect the unit from weather and water damage due to
rain, flooding, and freezing temperatures.
Do not install and operate the equipment in closed
systems unless the system is constructed with properlysized safety and control devices.
This facilitates ventilation, inspection, maintenance, and
service.
This makes it easier to properly use the lifting equipment
and safely remove and relocate the components to a safe
location.
This is applicable if nothing else is specified.
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.
Installation
Take into consideration the occurrence of abnormal noise
and vibration.
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.
The best pump location for noise and vibration
absorption is on a concrete floor with subsoil underneath.
AquaForce Variable Speed Package System Mechanical Installation, Operation, and Maintenance Manual13
Installation
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.
CheckExplanation/commentChecked
Check that the suction and discharge pipes are
supported independently by use of pipe hangers near
the pump station.
Check that there is a strong, rigid support for the
suction and discharge lines.
Check that the suction or discharge lines are not
forced into position.
Check that fittings for absorbing expansion are
installed in the system when considerable
temperature changes are expected.
This eliminates pipe strain on the pump
station.
As a rule, ordinary wire or band hangers are not
adequate to maintain proper alignment.
Component failure will result if suction or
discharge lines are forced into position.
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.
14AquaForce Variable Speed Package System Mechanical Installation, Operation, and Maintenance Manual
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).

WARNING:
• Failure to follow these precautions before you start the unit will lead to serious personal
injury and equipment failure.
• Do not operate the pump below the minimum rated flows or with the suction or
discharge valves closed. These conditions can create an explosive hazard due to
vaporization of pumped fluid and can quickly lead to pump failure and physical injury.
• 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.
• Operating the pump in reverse rotation can result in the contact of metal parts, heat
generation, and breach of containment.
NOTICE:
• Verify the driver settings before you start any pump.
You must follow these precautions before you start the pump:
• Flush and clear the system thoroughly to remove dirt or debris in the pipe system in

CAUTION:
Serious damage to the pump may result if it is started dry. Make sure that the pump is
completely filled with liquid before it is started.
CheckChecked
Check that the unit base is properly leveled, grouted, and secured.
Check that all lubrication points are properly lubricated.
Check that the outlet side of the high-temperature relief valve assembly (if option is
purchased) is connected to the drain with tubing or pipe sized 1/2 in. or greater.
Check that the shut-off valves to the transmitters are open.
Check that the pump and motor shafts are properly aligned.
Check that the pump rotation is correct.
Check that the piping is properly supported. This prevents strains on the unit.
Final adjustments
Make the final adjustments on these adjustable devices in order to match the exact system
requirements.
Thermal relief valve
An optional thermal relief valve is installed on the pump discharge in order to prevent
potentially dangerous thermal pressure buildup. The valve automatically opens on a
temperature increase and closes on a temperature decrease. This valve acts as a safety
device; do not remove or plug it. It is factory set to open and discharge when the water
temperature in the discharge header reaches between 125°F to 135°F (51°C to 57°C).
Make sure that the 1/2 in. NPT opening of this valve assembly is piped to a floor drain in
accordance with local codes.
After long periods of operation, the valve seat and disc can become worn or pitted. This
allows leaks through the valve in the closed position. You can replace internal parts, if
desired.
Low suction pressure switch (optional)
Adjust the setting to 10 psi below the rated suction pressure.

pressure exceeds the tank pressure rating.
Commissioning, Startup, Operation, and Shutdown
DANGER:
Explosion hazard. Prevent tank explosion. Install a pressure relief valve on the tank inlet
with a set point no greater than tank rating.
1. Precharge the storage tank before you connect it to the system.
The air precharge needs to be 5 to 10 psi less than the system operating pressure.
2. If the storage tank has already been installed and not precharged, then disconnect the
system piping from the tank and equalize it to atmospheric pressure. If an isolation
valve and drain are provided, then use them.
3. Apply air pressure to the tank through the air charging valve and pressurize to field
conditions.
This needs to be equal to the NFSD restart pressure of 5 to 10 psi below the operating
pressure.
4. Reconnect the tank to the system piping. Tank should be installed on the discharge
side of the system.
Check for available suction water
1. Open all supply, discharge, and pump isolation valves. Also open any other package
valves.
2. Close the bypass valve if it is installed in the piping by others.
3. Inspect the capillary tubing from the pump discharge to the suction header:
a) Open the petcocks that feed the tubing.
b) Make sure that the plastic tubing does not touch any metal surface. Protect the
tubing with insulation in order to prevent abrasion where it can possibly touch
metal.
4. Open a faucet in order to create a demand for water on the system pressure piping.
5. Observe the suction pressure and confirm that it is equal to or greater than the suction
pressure listed on the nameplate. System is designed for a specific suction pressure.
