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 (5) 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 (6) 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 (6) in the basin (5) so the tether switch (7) is
away from incoming water. Verify the tether float switch has
at least 1 inch clearance to the side wall of the basin and is
free of any possible obstructions.
6. Install discharge plumbing according to local, regional and
state codes. Do not reduce the discharge pipe (3) size
below that which is provided on the pump (6).
7. A union (2) should be installed above the basin to allow
easy removal of the pump (6) for cleaning and service.
8. Install a check valve (1) (required) to prevent back-flow.
It should be installed above the union.
9. A gate valve or ball valve should be installed above the
check valve if required by local, regional or state codes.
10. Connect remaining discharge pipe. Keep sections as short
as possible with a minimum number of turns.
11. A vent pipe (11) is required. It removes gases and odors
and should be installed as required by local, regional or
state codes.
12. Secure power supply cord (8) to discharge pipe (3) using
cable or zip ties to prevent possible switch entanglement.
13. Connect tether switch (7) piggyback cord to a ground fault
circuit interrupter (GFCI) outlet (9) (required) then connect
the pump power supply cord (8) into the piggyback cord.
14. 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.
15. Install a basin cover and gasket (10) to prevent debris from
falling into the basin, prevent personal injury, and to contain
gases and odors.
