STARTUP & PROGRAMMING 

The control valve is pre-programmed at factory. You can however change the default settings or to change regeneration 
frequency. We recommend setting backwash every 3 days with a minimum 10 minute backwash and 5 minute rinse cycle. If 
you have questions about programming, please call Rainfresh at 1800-667-8072. 

When power is first supplied, the valve electronics may take up to two minutes to initialize.  During this time the screen will 
show “INTIALIZING WAIT PLEASE”.  Do not touch any buttons at this time.  When the valve reaches the service position, it 
will display the following information in sequence:
