REPLENISHMENT OF SALT SUPPLY:
The salt storage capacity of the brine tank is approximately 160 lbs (72.6 kg). 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:
Any type of water softener salt may be used. There are advantages and disadvantages to every type of salt. Please ask your local dealer for advice. Your unit is
designed to compensate for the disadvantages. 3M does not recommend the use block type salt.
BRINE TANK CLEAN-OUT:
As part of routine maintenance, 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 salt used and regeneration frequency. The clean-out should be done when the salt level is low. Steps to follow:
(1) Disconnect brine line at either end.
(2) Turn brine tank upside down and discard old salt.
(3) Rinse out with a garden hose.
(4) Reconnect brine line.
(5) Add about 3 gallons of water (6 gallons 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 MINERAL BED:
If iron is present in the water supply, the softener mineral bed will eventually become iron-fouled, resulting in reduced softening capacity and rust-stained fi x-
tures. Mixing one to two ounces of Mineral Cleaner with every 80 lbs. of salt added to brine tank will minimize these problems from occurring. Mineral Cleaner
is available from your dealer.
PERIODICALLY CHECK TIME OF DAY SETTING:
Power outages will cause Time Of Day time clock setting to become incorrect. To reset, refer to appropriate How To Set Time Clock (Or Meter) Regeneration
Control page, 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 5, 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.
SPECIAL SERVICE INSTRUCTIONS:
Under normal circumstances removal of the valve should not be required. However, if it must be removed, disconnect the plumbing attached to the bypass valve
fi rst. Then, rotate the valve head assembly to the left or counter-clockwise. Before attempting any disassembly, pressure should be relieved by shutting off water
to the system and opening a faucet. Upon reassembly, all o-rings should be lubricated with silicone grease. Reattach valve head assembly by rotating to the right
or clockwise until valve head assembly is seated to the tank hand tight. Reconnect the plumbing to the bypass valve.
