Maintenance - Wayne 331301-001 Operating Instructions Manual

Installation
(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.
