Wil-Gard™ Diaphragm Sensor Installation
Step 1
The Wil-Gard™ sensor wires must be
installed between the primary diaphragm
and the back-up diaphragm, on both sides
of the pump, at the six o’clock position.
They should be positioned approximately
half the distance to the shaft from the edge
of the diaphragm.
Step 2
Prior to installing the liquid chamber, and
after positioning the Wil-Gard™ sensor
cable between the primary and back-up
diaphragms, run the sensor cable along the
diaphragm bead but outside the pump. Now
install the liquid chamber and large clamp
band.
Step 3
When installing the liquid chamber and large
clamp band, route the Wil- Gard™ sensor cable
to the inside of the large clamp-band fastener.
Next, reconnect the Wil-Gard™ module.
NOTE: Use caution to ensure that the
sensor wires are not damaged or
pinched by the clamp band.
