and your water supply is turned on.
3. Press and hold regenerate button
until controller advances to the next
step. Continue this process until you
see Brine Refill.
Allow the tank to fill with the proper
amount of water. The controller will then
advance the valve to Home position.
STEP 12 Fill Brine Cabinet With Salt
Fill brine cabinet with salt. Use clean white pellet, cube-style, or solar salt.
Do not mix pellet with solar salt.
NOTICE: Always keep the salt level above the water level. For convenience, fill the cabinet 3/4 when
refilling with salt.
If salt level was below water level before salt was added, wait two (2) hours for
saturated brine before starting any regeneration.
NOTICE: Use of potassium chloride when iron and/or manganese are present in the raw water
supply is not recommended.
STEP 13 Complete the Installation
1. Ensure bypass valve is left in the Service position. (see Service Position above)
2. Ensure water supply is on.
3. Open inlet valve and turn on electricity to water heater. For gas water heaters,
return the gas cock to "On."
4. Turn on a cold water tap and allow water softener to flush for 20 minutes or until approx.
72 gallons (270 L) have passed through. It is normal to see dark colored water from faucets
when first flushing the softener. This procedure is required to meet NSF compliance. Verify
the controller indicates water flow. (See Step 10 - Setting the Controller)
