Operating Instructions
16. Do not handle a pump or pump motor
with wet hands or when standing on a
wet or damp surface, or in water.
17. Do not hang this product by the
carry handle. Sewage pumps should
be set firmly on their legs and
supported by rigid piping. This
eliminates twisting and damage
during pump operation.
18. Do not use an extension cord.
Do not walk on wet area until
all power has been turned off.
If the shut-off box is in
basement, call the electric company to
shut-off service to the house, or call the
local fire department for instructions.
Remove pump and repair or replace.
Failure to follow this warning can result
in fatal electrical shock.
Installation
In any
Installation
where property damage and/or personal
injury might result from an inoperative or
leaking pump due to power outages,
discharge line blockage or any other
reason, use a backup system(s).
1. Thread the discharge pipe or pipe
nipple into the dis charge connection.
2. If a check valve is used in a solids
handling system mount the check
valve in a horizontal position or at a
45° angle with the valve pivot on
top. In a vertical position, solids will
tend to lodge on the valve flapper
and can prevent it from opening.
3. Drill a 1/16" hole in the discharge
pipe ap prox i mate ly 1" to 2” above
the pump discharge when a check
valve is used. The hole prevents air
locking of the pump at the initial
start-up and if it should lose prime.

Information (Continued)
4. A gate valve should be installed in the
system after the check valve. This gate
valve should be a full port valve which
will pass 2" solids or as required by
state and local codes. This gate valve
permits removal of the pump and/or
check valve for servicing.
5. A union should be installed between
the check valve and the pump so the
pump can be removed with least
disturbance of the piping.
6. The RPP50 pump has a detachable
tether switch with a piggyback plug
(see Figure 3A). The length of the
tether (distance of cord from float to
clamp) should not be set shorter than
3-1/4 inches and should not be used in
a basin smaller than 14 inches in
diameter. If using a differential other
than the factory setting, be sure
when the pump shuts off at least 4”
of fluid is left in the basin so the
impeller remains submerged.
7. When any switch is used, rigid dis charge pipe is required. If the pump is
allowed to move, the tether switch
could be re strict ed by the basin wall,
pre vent ing the pump from operating.
8. RPPCAP50 models are supplied with a
“Switch Genius” capacitive water
sensor. Orient the pump in the basin
so that the “Switch Genius” water
sensor is 180° away from the inlet.
3
Make certain the incoming water
stream does not hit the “Switch
Genius” surface (See Figure 3B).
Before
removing
pump from basin for service, always
disconnect electrical power to pump
and control switch. For any work on
pump or switch, ALWAYS unplug the
power cord. Do not just turn off circuit
break er or unscrew fuse.
Maintenance
Make
certain
that the pump is unplugged before
attempting to service or remove any
component. This pump is assembled in
the factory using special equipment;
therefore only authorized service dealers
or qualified electricians should attempt
to repair this unit. Improper repair can
cause an electrical shock hazard.
The pump
contains
oil that may be under pressure because
of heat. Let the pump cool for a minimum
of two hours before servicing this unit.
1. Disassembly of the motor prior to
expiration of war ran ty will void the
warranty. It might also cause internal
leakage and damage to the unit. If
repairs are required, return the pump
to the dealer from whom it was pur chased or call 1-800-237-0987.
2. After the basin cover is removed
and necessary dis charge piping
disconnected, lift pump from basin.
