Maintenance - 3M 3MWTS Series Installation And Operating Instructions Manual

SECTION 4: MAINTENANCE
Replenishment of Salt Supply:
The salt storage capacity of the brine tank is approximately 82 kg. During each regeneration a specific 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.
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 advice. 3M Purification does not recommend the use of block type salt.
Brine Tank Clean-Out:
To help prevent service problems the brine tank should be emptied and flushed out with a garden hose annually or when dirt and other
insoluble 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.
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 fixtures. Mixing one to two ounces of Iron Reduction Media with every 36 kg. of salt added to brine tank will
help minimize these problems from occurring.
Please contact our Technical Service at 1300 345 837 for additional information.
Periodically Check Time of Day Setting:
Please contact your Dealer/Installer or our Technical Service at 1300 345 837 for additional information.
Periodically Check Time of Day Setting:
Power outages of eight hours or more will cause "TIME OF DAY" setting to become incorrect. To correct, refer to Section 3.
Malfunction of Unit:
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 18 for additional information).
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. Please contact our Technical Service at 1300 345 837 for additional information.
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 first. 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.
