INSTALLATION
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.
For guide rail systems, the pit floor must be flat under the guide rail base with sufficient loading
capacity to support the entire weight of the system.
In guide rail system installations, install the pump opposite the influent opening to prevent stagnant
areas where solids can settle.
1.
Install the pump in a suitable gas-tight basin vented in accordance with local, state, and federal plumb-
ing codes.
2. Place the pump-basin assembly on a hard, level surface.
IMPORTANT: 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.
3. Install discharge piping.
Do not use piping smaller than the pump discharge.
Use ABS, PVC, polyethylene, stainless steel, or galvanized steel pipe.
For rail systems, use proper adapters to connect nonmetal pipe. Refer to the instructions supplied
with the system.
4. 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.
5. 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.
6. Install a shut off valve following the check valve to allow for cleaning of the check valve or pump
removal.
