• Make sure the unit is properly installed with all piping complete
• All of the required media has been properly loaded in the tank

With all piping and installation completed, and with the mineral in the tank, proceed as follows:
1. Open the manual by-pass valve. The manual inlet and outlet valves are to remain closed.
2. Connect the power to the MX III controller. The controller display window will light up.

4. Open the cover of the enclosure and manually rotate the stager to the #1 (BACKWASH) position. The stager mo-
tor will rotate back to the #4 (SERVICE) position. This is done to conrm the controller’s homing signal is opera-
tional.
5. Press and hold the EXTRA CYCLE button on the front of the controller. This will advance Unit 1 to the backwash
step. The Unit 1 stager should rotate to the step 1 (BACKWASH) position.
6. Slowly open the softener’s manual inlet supply valve. Do not open fully. Full ow of water could cause loss of me-
dia. Continue to ll slowly until all air is expelled and only water ows to the drain. Water will enter from the bottom
of the resin tank as air is expelled from the top drain. If the system is supplied with an air vent make sure that the
valve is open during this process.

Backwash until the water looks clean when caught in a container.

rotate to the STEP 2 (BRINE/SLOW RINSE) position. There will be a slow ow to the drain.
9. While the unit is in the Brine/Slow Rinse position, check the level in the brine tank. The level should be dropping
at a slow rate (approximately 2” per minute).
