OTHER FEATURES 

 

Control Operation during a Power Failure  

 

In  the  event  of  a  power  failure,  the  valve  will  keep  track  of  the  time  and  day  for  48  hours.    The 
programmed settings are stored in a non-volatile memory and will not be lost during a power failure.  If 
power  fails  while  the  unit  is  in  backwash,  the  valve  will  finish  backwash  after  power  is  restored.    If  the 
valve misses a scheduled backwash due to a power failure, it will queue backwash at the next backwash 
time once power is restored. 

 

New Sounds 

 

You  may  notice  new  sounds  as  your  iron  filter  operates.  The  backwash  cycle  lasts  approximately  15 
minutes. During this time, you may hear water running intermittently to the drain. 

 

Care of Your Iron Filter 

 

To retain the attractive appearance of your new Iron Filter, clean occasionally with mild soap solution.  Do 
not use abrasive cleaners, ammonia or solvents.
