System Description: 

 

The softener tank has a Logix top mounted automatic control valve 
with an impulse meter to initiate regeneration.  The Logix Valve is 
constructed of non-corrosive Noryl

 material and is rated at a 

maximum working water pressure of 100 psi.  This softener includes 
a manually operated bypass device which enables the softener to be 
isolated from the water service lines for maintenance and service 
while maintaining the continuity of the (untreated) water supply.  It 
uses a 762 microprocessor based timer in conjunction with an 
internal impulse meter to actuate regeneration in the following ways: 
 

a. Microprocessor based water meter to initiate regeneration 
b. Manual regeneration button to start an emergency 

regeneration 

c. Calendar day override 
 

  NOTE:     THIS SOFTENER IS NOT INTENDED TO BE USED FOR TREATING WATER THAT    
                  IS MICROBIOLOGICALLY UNSAFE OR OF UNKNOWN QUALITY WITHOUT  
                  ADEQUATE DISINFECTION WHETHER BEFORE OR AFTER THE SYSTEM.
