- Page 5 Check Your Pumping Rate and Water Pressure: Two water system conditions must be checked carefully to avoid unsatisfactory operation or equipment damage: 1) MINIMUM water pressure required at the water softener inlet is 20 psi (138 kPa). IF WATER PRESSURE IS OVER 80 psi (552 kPa), A PRESSURE RE- DUCING VALVE MUST BE INSTALLED IN THE WATER SUPPLY LINE AHEAD OF THE WATER SOFTENER.
- Page 6 Facts to Remember While Planning Your Installation: 1) All installation procedures MUST conform to local and state plumbing codes. 2) If lawn sprinkling, a swimming pool, or geothermal heating/cooling or water for other devices/activities are to be treated by the water softener, a larger model MUST be selected to accommodate the higher fl...

- Page 14 SECTION 4: MAINTENANCE Replenishment of Salt Supply: The salt storage capacity of the brine tank is approximately 180 lbs. (82 kg). During each regeneration a specifi c amount of salt is consumed, thus requiring its periodic replenishment for a continuous supply of softened water (the frequency and salt dosage level is dependent on the regeneration schedule). Always replenish salt before the supply is exhausted.

Twist a fl at blade screwdriver in the slot between the control valve body and the meter. When the meter is part way out it is easy to remove the water meter from the housing. Once the water meter is removed from the control valve body, gently pull forward on the turbine to remove it from the shaft.
