MAINTENANCE
Adding Salt
Fill the salt tank only with nugget or pellet salt that is specifically for water softeners only. DO NOT USE rock salt,
road salt or other types of impure salts. Use only high grade water softener salt (Sodium Chloride). You can use
Potassium Chloride but you will need to increase salt settings (see page 12). Check the salt level monthly. It is
important to ALWAYS maintain the salt level above the water level. To add salt, simply slide open the salt tank lid
and add the salt directly into the brine tank. Be sure the brine well cover is on and fill only to the height of the brine
well. The salt tank should never be empty.
DO NOT OVERFILL THE SALT TANK TO THE TOP. 2-3 bags at a time are enough.
YOU WILL NOT BE ABLE TO SEE THE WATER ONCE YOU ADD A COUPLE OF BAGS OF SALT. IF YOU WANT
TO CHECK THE WATER LEVEL, OPEN THE LID ON THE BRINE WELL.
Preventing and breaking a Salt Bridge
Humidity or wrong type of salt may create a cavity between the water and the salt. This action,
known as “bridging”, prevents the brine solution from being made, leading to your water supply
being hard. If you suspect salt bridging, pour some warm water over the salt to break up the
bridge. Allow four hours to produce a brine solution, and then manually regenerate the softener.
This should always be followed up by allowing the unit to use up any remaining salt and then
thoroughly cleaning out the brine tank.
If you are unable to break the bridge this way, take a strong rod and carefully push down the salt,
working it up and down. Do not pound on the walls of the tank. If the wrong kind of salt has been
used, take it out and fill with nugget or pellet salt.
Care of Your Softener
To retain the attractive appearance of your new water softener, clean occasionally with mild
soap solution. Do not use abrasive cleaners, ammonia or solvents.
Cleaning the Injector Assembly
Sediment, salt and silt will restrict or clog the injector. A clean water supply and pure salt will prevent this from
happening. The injector assembly is located on the right side of the control valve. This assembly is easy to clean.
Shut off the water supply to your softener and reduce the pressure by opening a cold soft water faucet. Using a
screwdriver, remove the two screws holding the injector cover to the control valve body. Carefully remove the
assembly and disassemble as shown in Figure 6. The injector orifice is removed from the valve body by carefully
turning it out with a large screwdriver. Remove the injector throat the same way. Carefully flush all parts including
the screen. Use a mild acid such as vinegar to clean the small holes in the orifice and throat.
Reassemble using the reverse procedure.
