Physical Installation
High voltages capable of causing severe injury or death by electrical
shock are present in this unit.
• Always disconnect the electrical power before touching the pump or discharge.
• Check local electrical and building codes before installation. The installation must be made in accordance with
their regulations as well as the most recent National Electrical Code (NEC) and the Occupational Safety and
Health Act (OSHA).
Risk of damage to pump or other equipment.
• Support pump and piping when assembling and when installed. Failure to do so may cause piping to break, pump
to fail, motor bearing failures, etc.
• If the relief hole in the discharge pipe is not provided, the pump could "air lock" and will not pump water even
though it will run.
• A missing, improperly installed, or malfunctioning check valve can cause a pump to short-cycle due to back-flow
of the pumped fluid from the discharge plumbing back into the basin, significantly shortening the life of the
pump.
1. Install the pump in the center of a suitable gas tight basin that is at least 18 inches (45.72 cm) in
diameter and 30 inches (76.2 cm) deep and vented in accordance with local plumbing codes.
• Ensure sump is clean and free of nails, gravel, string, cloth, or other debris before installing.
• Provide adequate room for future servicing, protection from freezing temperatures, flooding,
and equipment drainage.
• Never place the pump directly on clay, earth, or gravel surfaces.
IMPORTANT: Do not attempt to restrict the intake side of the pump.
2. Connect discharge piping.
• Use ABS, PVC, polyethylene, stainless steel, or galvanized steel pipe.
• The discharge pipe should be as short as possible and contain as few elbows as possible.
• Do not use piping smaller than the pump discharge.
• Use pipe joint compound or PTFE tape at all threaded connections.
• For rail systems, use proper adapters to connect nonmetal pipe. Refer to the instructions sup-
plied with the system.
3. Install a union in the discharge line just above the basin cover.
4. Install a full-flow check valve horizontally in the discharge line.
5. Install a gate valve in the discharge line.
6. Install a tethered float switch.
• Refer to manufacturer's instructions.
7. Tape the pump and switch cords to the discharge piping with electrical tape.

between the pump discharge and check valve.
• Drill this hole at a 45 ° angle below the horizontal plane and away from the pump.
9. Install a separate vent.
NOTE: A connection is provided on top of the sump or cover which must be piped according to
code, either to the existing building vent or extended outside with its own standpipe.
