Replacing The WPLLD Sensor
Checking the Functional Element Orifice (For Red Jacket Pumps)

WPLLD Sensor Installation
1. Remove the protective plastic cap from the WPLLD sensor.
2. If the sensor is being installed at altitudes above 2,000 feet, open the vent screw at
least two turns, but not more than three turns, to vent any internal pressure.
(WPLLD sensors are equipped with a vent screw to equalize internal pressure.)
3. Retighten the vent screw securely to prevent water from entering. (Failure to
release internal pressure in the WPLLD sensor at altitudes above 2,000 feet could
cause inaccurate pressure readings and false line leak alarms.)

Cut the orange wire (FE Petro
pumps) or the yellow wire
(Red Jacket pumps) running
through the motor capacitor
storage well and strip each end
to expose 1/2-inch of bare
wire. Twist the wire nut over the
two ends of the colored wire
you just cut and stripped and
the already stripped end of one
of the black wires from the
Wireless Line Leak Sensor.

Vent screw - If you are installing
this sensor above an altitude of
2000 feet you must loosen this
screw (2 - 3 turns CCW) to
release any internal pressure,
and then retighten the screw.
Cut the black wire from
the power source to the capacitor
and strip each end to expose
1/2-inch of bare wire. Twist
the wire nut over the two ends
of the black wire you just cut
and stripped and the already
stripped end of one of the black
wires from the sensor.
