housings on the set prefilter bracket.
3. Fully open the concentrate valve by turning it counterclockwise. Fully close the recycle valve by
turning it clockwise. Next, turn on the water feed to the system and then provide power to the
unit. The system will turn on automatically when it detects sufficient feed water. Let the unit
flush for 30 minutes, this will remove the winterization solution.
4. After 30 minutes of flushing, power off the unit. Hook up the roduct to Tank connection, the
eed from Desalinator and reset the recycle and concentrate valves to their normal operating
positions. The unit is now ready for operation.
