INSTALLATION
Physical Installation
Physical Installation
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 24 inches (60.9 cm) deep and vented in accordance with local plumbing codes.
• Place pump in an upright position on a hard, level surface in the water reservoir.
• 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.
• If reduced flow rates are required, place a valve on the discharge side of the pump.
• If flexible vinyl tubing is used, add a clamp on the tubing to restrict the flow.
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.

8. Drill a / inch (0.48 cm) diameter relief hole in the discharge pipe below the floor line between the
16
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.
10. Connect the pump to an appropriate power supply. Refer to
11. Confirm that the pump is functioning as intended.
12. Place cover over basin.
