Removing the Electronics Box

2. Unplug the the data cable from the control box.                                                                                                                                                                       


3. On the bottom of the electronics box you will find a Phillips screw. Remove this screw to release the electronics box.                                                                                                 


4. Gently pull the electronics box a few inches from the control box. There are five wires still connected, so do not pull this too far.                                                  


5a. Find the two connectors on the back of the electronics box. Three wires are attached with one connector and two wires with the other connector. For each connector, gently depress the tab.


5b. Slide the connector away from the electronics box. This will free the electronics box from the main control box.                                                                


Installing the New Electronics Box

1a. Attach both connectors to the new electronics box.                                                                                


1b. Push each connector until it snaps into the base.                                                                                              



2. Push up gently on the electronics box to the control box. Use caution to prevent pinching or damaging the wires.


3. Assemble the screw to the electronics box.                                                                                                               


4. Insert the data cable to the data port on the bottom of the control box. Push to secure.

3. Carefully press the tab with a flathead screwdriver to swing open.

4. Press the end of the tab to release the wire connector. Do this for both tabs. Pull the connectors away from the base.    



Installing The New Electronics Box

1. Align the red mark on the tab with the red dot on the electronics box. Inset the connectors from the new control box into the base of the electronics box.


2. Push each connector until it snaps into the base.



3. Insert the top of the electronics box into the control box. Swing closed until the tab locks in (Use caution to prevent pinching or damaging the wires).     


4. Insert the data cable to the data port on the bottom on the control box. Ensure the cable is pushed all the way into the control box. The data cable plug goes into a two-stage socket. To insure this is fully inserter, push the plug until it feels like it is seated in the socket, then apply a little extra pressure until it locks into the socket and is fully seated.                               


5. Insert the battery pack or AC adaptor to the control box power port. Ensure the cable is pushed all the way to the control box. Push the cable until it can not be pushed any farther  

Before connecting the battery holder or optional AC adapter with the power splitter, ensure that there are no people or objects are within 3 feet of the faucet. These could interfere with the start up process.
