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.
Assemble the three volute casting legs, leg bolts
and nuts, and volute, then tighten with a 1/2-inch or
crescent wrench.
2. Install the pump in a suitable gas-tight basin at least
24 inches in diameter and 48 inches deep, vented in
accordance with local, state, and federal plumbing
codes.
3. Place the pump-basin assembly on a hard, level sur-
face.
•
Never place pump directly on clay, earth, or
gravel surfaces.
•
Secure the pump so the starting torque does
not cause the pump to contact anyone or any-
thing.
4. Install discharge piping.
•
Do not use piping smaller than the pump dis-
charge.
•
Use ABS, PVC, polyethylene, or stainless steel
pipe.
•
For rail systems, use proper adapters to connect
nonmetal pipe.
5. Install a full-flow check valve in the discharge line horizontally.
•
A ball check valve is recommended.
NOTE: If installed vertically, solids may settle in the valve and prevent it from opening at start-up.
6. Drill a 3/16-inch diameter relief hole in the discharge pipe below the floor line and between the pump
discharge and check valve.
NOTE: If not provided, the pump could "air lock" and will not pump water even though it will run.
7.
Install a shut-off valve following the check valve.
