1. If the white connector is not fully accessible then the
sensor module must be removed from the case in order
to reassemble the solenoid connector to the sensor

2. Remove the battery cover (Item #10) from the RetroFlush
sensor assembly (Item #9).
3. Remove the battery case (Item #15) and disconnect from
the sensor.
4. Remove the sensor module (Item #12) held in place by
two screws (Item #13) and rubber plug (Item #14).

grease provided to prevent damage while reassembling
the unit. Insert the solenoid (Item #7) into the housing
and install the solenoid retaining clip (Item #8). When
installed properly, the end of the solenoid is free to rotate.
Notes: Be careful not to crimp the battery wires while
inserting the solenoid into the housing. Also, be sure
the blue and gray wires of the solenoid valve extend
into the sensor module cavity of the housing (Item #9).
6. Connect the sensor module blue and gray wires to the
solenoid valve blue and gray wires and reinstall the
sensor module.
Note: Be very careful not to crimp the
wires when reinstalling the sensor module. Replace
the two screws (do not over tighten) and rubber plug
holding the sensor module in place.
7. Replace the battery pack and reconnect to the sensor.
