SECTION 7: MAINTENANCE
REPLENISHMENT OF SALT SUPPLY:
The salt storage capacity of the brine tank is approximately 160 lbs. During each regeneration a specifi c amount of salt is consumed, thus requiring its periodic
replenishment (the frequency is dependent on the regeneration schedule). Always replenish salt before the supply is exhausted to assure a continuous supply
of softened water.
TYPE OF SALT TO USE:
Most types of water softener salt may be used. There are advantages and disadvantages to every type of salt. Please ask your local dealer for his advice. Your
unit is designed to compensate for the disadvantages. 3M Purifi cation does not allow the use of block type salt with water softeners.
BRINE TANK CLEAN-OUT:
To prevent service problems the brine tank should be emptied and fl ushed out with a garden hose when dirt and other insolubles accumulate. The clean-out
frequency depends on the type of salt used and regeneration frequency. The clean-out should be done when the salt level is low. Steps to follow:
1)
Disconnect brine draw line at either end.
2) Turn brine tank upside down and discard old salt.
3) Remove the salt grid platform and rinse out with a garden hose.
4) Reinstall salt grid platform and reconnect brine line.
5) Add about 3 gals. of water (6 gals. for units with extended grid legs) to brine tank before adding new salt. Perform approximately once a year if rock salt
is used; with other types of salt, approximately once every other year.
PREVENTING IRON-FOULING OF MEDIA BED:
If iron is present in the water supply, the water softener media bed will eventually become iron-fouled, resulting in reduced softening capacity and rust-stained
fi xtures. Mixing one to two ounces of Iron reduction media with every 80 lbs. of salt added to brine tank will minimize these problems from occurring. Iron
reduction media is available from your dealer.
PERIODICALLY CHECK TIME OF DAY SETTING:
Power outages will cause Time Of Day timer setting to become incorrect. To reset, refer to appropriate refer to appropriate instructions on how to set back-
washing control in Section 3.
MALFUNCTION OF UNIT:
Your water softener, under normal conditions, should provide years of trouble-free service; however, since it is a mechanical device, it can malfunction. (Refer
to Section 4, SERVICE INSTRUCTIONS, if necessary).
CHANGE OF OPERATING CONDITIONS:
Should your family size, your water usage habits, or your water quality change, the regeneration program settings may have to be adjusted. Consult your
dealer if any of the above occur.
