INSTALLATION
Physical Installation
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.
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.
