INSTALLATION MANUAL

TYPICAL SEWAGE 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 basin diameter should be a minimum of 18 inches and
the depth a minimum of 24 inches.
3. Clean the basin of all debris.
4. 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.
5. Position pump in the basin so the switch is away from
incoming water. Verify the fl oat switch has at least 1 in.
clearance to the side wall of the basin and is free to move
throughout it’s movement.
6. Install discharge plumbing according to local, regional and
state codes. Do not reduce the discharge pipe size below
that which is provided on the pump.
7. Drill a 1/8 in. “weep” hole in the discharge pipe 1 in. above
the pump discharge. Water stream will be visible from this
hole when the pump is running. The hole must be cleaned
periodically.
8. If optional control device or fl oat is used, follow mounting
instruction supplied with device or fl oat.
9. Install a sealed basin cover to prevent debris from falling into
the basin, personal injury and contain gases and odors.
10. A union should be installed above the basin to allow easy
removal of the pump for cleaning and service.
11. Install a check valve (required) to prevent back-fl ow. It
should be installed above the union.
12. A gate valve or ball valve should be installed above the
check valve as required by local, regional or state codes.
13. Connect remaining discharge pipe. The remainder of
the discharge line should be as short as possible with a
minimum number of turns.
14. A vent pipe is required. It removes gases and odors and
should be installed as required by local, regional or state
codes.
15. Secure cords to discharge pipe to prevent possible
switch entanglement. Use cable or zip ties to secure the
power cords.
16. Connect pump power supply cord to a properly grounded
receptacle
17. Fill the basin with water. The pump will start when the water
level has reached the switch-on level. Verify the pump is
operating normally.
