Maintenance; Replenishment Of Salt Supply; Brine Tank Clean-Out; Iron-Fouling Of Mineral Bed - 3M 3MWTS100 Installation And Operating Instructions Manual

The salt storage capacity of the brine tank is approximately 180 lbs. (82 kg). During each regeneration a specifi c amount of salt is consumed, thus requiring
its periodic replenishment for a continuous supply of softened water. The frequency and salt dosage level is dependent on the regeneration schedule. Always
replenish salt before the supply is exhausted.
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 advice. 3M
Purifi cation does not recommend the use of block type salt.
To help prevent service problems the brine tank should be emptied and fl ushed out with a garden hose annually or when dirt and other insolubles accumulate.
The clean-out should be done when the salt level is low. Do not perform this clean-out procedure during regeneration cycle.
Steps to follow:
(1) Disconnect brine line at either end.
(2) Turn brine tank upside down and discard old salt.
(3) Remove the salt shelf and rinse both the tank and salt shelf with a garden hose.
(4) Reinstall salt shelf and reconnect brine line.
(5) Before loading salt, using a pail or garden hose, add enough water to the brine tank to cover the lower portion of the salt shelf. Then add salt to brine tank.
Add one (1) cup of unscented laundry bleach to the brine well to sanitize the system.
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 xtures. Mixing one to two ounces of Iron Reduction Media with every 80 lbs. of salt added to brine tank will help minimize these problems from occurring.

Power outages of eight hours or more will cause "TIME OF DAY" setting to become incorrect. To correct, refer to Section 3.
Your water softener, under normal conditions, should provide years of virtually trouble-free service; however, since it is a mechanical device, it can malfunction.
(Please refer to our Troubleshooting Guide under Section 6, page 6-1 for additional information).
Should your family size, your water usage habits, or your water quality change, the regeneration program settings may have to be adjusted. Please contact
our Customer Care Team at 855-3M-WATER (855-369-2837) for additional information.
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.
