Physical Installation
Risk of personal injury, or damage to pump or other equipment.
• Check that lifting equipment complies with all safety rules, and is suitable to support the weight of
the pump.
1. Install the provided leg accessory kit:
• Remove the three shipping bolts from the volute casting legs using a 19 mm wrench or crescent
wrench.
• Screw the nut all the way onto the removable leg bolt.
• Screw the leg bolt and its nut onto the volute casting legs hand tight.
• Tighten the nut against the volute casting with a 19 mm wrench or crescent wrench.
2. If purchased with a vertical switch, install it using a P1 size Phillips screwdriver:
• Screw the bracket onto the switch with the two self-tapping screws.
• Assemble the vertical switch and its bracket onto the motor housing cover using the 2 M4 screws.
3. Install the pump in a suitable gas-tight basin at least 20" diameter and 24" deep vented in accordance
with local, state, and federal plumbing codes.
4. Place the pump-basin assembly on a hard, level surface.
• Never place pump directly on clay, earth, or gravel surfaces. These surfaces contain small stones,
gravel, sand, etc. that may clog or damage the pump and cause failure.
• Secure the pump so the starting torque does not cause the pump to contact anyone or anything.
5. Install discharge piping.
• Do not use piping smaller than the pump discharge.
• Use ABS, PVC, polyethylene, or galvanized steel pipe.
• For rail systems, use proper adapters to connect nonmetal pipe.
6. Install a full-flow check valve in the discharge line horizontally to prevent back flow of liquid into the
basin.
• A ball check valve is recommended.
• If installed vertically, solids may settle in the valve and prevent it from opening at start-up.
7. Drill a 3/16" diameter relief hole in the discharge pipe below the floor line between the pump discharge
and check valve.
• If not provided, the pump could "air lock" and will not pump water even though it will run.
8. Install a shut off valve following the check valve to allow for cleaning of the check valve or pump
removal.
