External Micro-SD Adapter Upgrade Instructions.

To complete the upgrade, you will need a 20mm carbide hole saw to drill through the aluminum box to mount the remote micro-SD housing.

Before starting, it is best to remove the Unity controller to be able to work on it more easily.

First, you will want to locate the drill point on the top side of the box.  

There is a 3d printable bracket that can help with this, or use a ruler/measuring tape to mark the drill point.

Make sure the box cover plate is removed so that you can see and verify there is clearance inside the box. 

Next, drill the hole through the aluminum box, being very careful not to allow the bit to run inside the box.

Once the hole is made, if needed, you can clean the edges with a deburring tool or razor knife if there are any sharp metal filings left.   

Very Important: Be sure to vacuum or blow out all of the aluminum chips so that they do not damage any of the components inside.

Next, remove the micro-SD card from the housing on the board.  There are videos on YouTube showing how to do this.  See Here.

Next, install the remote micro-SD housing by passing the extension cable through the outside of the box and running the cable through the back nut.  Tighten the nut on the inside of the box, and you can rotate the housing on the outside to help with this.

Now, align the tip end of the extension cable into the SD holder on the control board and close the hinged clamp. This can be a little tricky so be patient. 

Now you can re-install the micro-SD into the new housing. 

 Lastly, test the unit out by plugging the controller into the main power and Ethernet before re-mounting the control box on the filtration unit, in case you need to re-seat the extension on the board. Once you verify that the controller and new SD adapter are working correctly, you can reinstall the Unity controller onto the filtration unit.
