will add water to the brine cabinet. Do not add
water at any other time.

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 tank 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.

and/or manganese are present in the raw water
supply is not recommended.
