For your new system to operate properly, you may need to clean the entire plumbing system of the precipitated iron that has collected in it or iron "bleed"
(staining) will continue to be a problem. The plumbing system includes all water treatment equipment (such as water softeners), water heaters, toilets,
and dishwashers. Please refer to the appropriate owner's manual for instructions.
To ensure optimal performance of the 3MAPPM Residential Iron Reduction System, you should check the water quality and verify the level of the filter
media every three (3) months. It will be necessary to perform maintenance on your filtration system in order to ensure continued performance. This is
due to low pH, high manganese and/or the sacrificial nature of the filter media. The severity of your pH or the amount of water used will determine how
often the filtration system will need to be serviced. To correct this condition, it will be necessary to add pH Plus to the filter bed. To correct this condition,
it will be necessary to add pH Plus to the filter bed, which can be purchased as a single unit or in a case of 6. Either of these items can be purchased
through your Dealer/Installer or our Customer Care Team at 855-3M-WATER (855-369-2837) . pH Plus is a pH boosting material that replenishes the same
material that was dissolved into your water to make iron and manganese reduction possible.
3M Purification Inc. recommends that you test your treated water pH once every three (3) months. When Iron is the only problem, a water pH needs to
be 7.2 higher. When manganese and iron are present, the treated water pH needs to 8.2 or higher. The levels can be checked on location with the use of
an inexpensive pH test kit that can be purchased locally or from 3M Purification. Our part number is "17N". When the pH falls below the recommended
level and iron or manganese is bleeding through into the finished water, it is time to add the pH Plus component to the filtration system. The amount of
material to add to a filtration system is as follows.
Standard bed filters
1- 3 ½ pound container of pH Plus for each cubic foot of filter material
Step By Step Procedure To Add Iron Reduction Replacement Media (pH Plus) To Your Iron Reduction System.
1)
Turn the inlet and outlet knobs of the bypass valve located on the back side of the control valve. See Figure 5, page 3-5 in Section 3 for proper
orientation.
2)
Manually initiate a backwash cycle to relieve water pressure from the inside of the filtration system.
3)
Remove the dome hole cap by rotating the cap to the left (counter clockwise) for access to the
media tank.
4)
Using a 1/2" diameter flexible tubing, siphon about 12" of water from the media tank to allow for
adding the pH Plus.
5)
Using the optional dome hole funnel (part # 6238731), pour the recommended amount of pH Plus
into the filter media and add water back to filter to expel any air pockets in the media tank.
6)
Remove funnel and clean the threads of the mineral tank dome hole to ensure fines or media are not
trapped in them. Replace the dome hole cap in media tank by rotating the cap to the right (clockwise).
7)
Slowly open the inlet side of the bypass and pressurize the filter, check for leaks, correct if necessary.
8)
Manually stage the control to backwash and clean the filter media of any fines that would be present until clear. Allow the control to complete regenera-
tion cycle completely and return to service. Refer to "HOW TO MANUALLY INITIATE IMMEDIATE REGENERATION", page 3-7.
9)
Slowly open the outlet side of the bypass and pressurize the dwelling.
