INSTALLATION MANUAL
TYPICAL SUMP INSTALLATION
1.This installation must be in accordance with the National Electric Code and all applicable local codes and ordinances.
2.Use a basin that is large enough to accommodate the pump. The minimum requirements for the sump pumps are:
8.Drill 1/8 in. “weep” hole in the discharge pipe 1 in. above the pump discharge. Water stream will be visible from the how when the pump is running. The hole must be cleaned periodically.
9.Install a union to allow for easy removal of the pump for cleaning or service.

3.Clean the basin of all debris. Position pump so the switch is away from the inlet and is clear from incoming water.
4.Assemble switch or float if needed. Refer to warranty and service parts sheet for specific directions.
5.Set the pump on a solid, level surface. Do not place pump directly on clay, earth, gravel or sand. A brick or block may be installed under the pump to provide a solid base.
6.Position pump so the switch is away from the inlet so switch is clear from incoming water. Verify the switch has at least 1 in. clearance to the side wall of the basin and is free to move throughout its movement. If optional control device or float is used, follow mounting instruction supplied with device or float.
7.Install discharge plumbing according to local, regional
and state codes. Rigid PVC pipe is recommended.
10.Install a check valve (required) to prevent
11.Install a gate valve or ball valve if required by local, regional or state code.
12.Secure cords to discharge pipe to prevent possible switch entanglement. Use cable or zip ties to secure the power cords.
13.Connect pump power supply cord to a properly grounded receptacle.
14.Fill the basin with water. The pump will start when the water level has reached the
15.The pump will stop when the water level has reached the
16.Verify the switch is operating with out any obstruction from the pump, piping and basin.
17.Fill the basin with water again. While the pump is draining the basin, verify the discharge pipe is carrying the water to a point at least 3 ft. away from the foundation. If the discharge line is exposed to freezing temperatures, the pipe must be positions in a downward slope away from the foundation so any remaining water will drain away and not freeze.
