1. Before operating the Sewage Pump,
put on ANSI-approved safety gog-
gles and other safety gear including
heavy-duty, insulated rubber gloves.
Safety goggles and other safety gear
are sold separately.
2. If you use a check-valve (not sup-
plied), mount the check valve hori-
zonally or at 45°. The valve pivot
should be on top. NOTE: If the
check valve should be mounted in a
vertical position, solid waste will tend
to lodge on top of the valve flapper
preventing it from opening.
2. Install the Sewage Pump firmly on it’s
Legs and supported by rigid hose, or
pipe discharge fixtures to eliminate
twisting and damage from motor
torque during operation.
3. If using a check-valve, drill a 1/16”
hole in the discharge hose, or pipe 1”
to 2” above the Base (27). The hole
will prevent an air lock in the Mo-

age Pump to flood with water before
plugging Power Cord (1) into outlet.

outlet, the Motor (18) will start auto-
matically.
