Section 7: MAINTENANCE
Plumbing System Clean-Up
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.
General Maintenance
To ensure optimal performance of the APPM Residential Iron Reduction System, you should check the water quality and verify the level of the fi lter media
every three (3) months. It will be necessary to perform maintenance on your fi ltration system in order to ensure continued performance. This is due to
low pH, high manganese and/or the sacrifi cial nature of the fi lter media. The severity of your pH or the amount of water used will determine how often
the fi ltration system will need to be serviced. Either of these items can be purchased through your Dealer/Installer or our Customer Service Department
at 1-800-222-7880. 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 Purifi cation 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 Purifi cation. Our part number is “17N”. When the pH falls below the recommended
level and iron or manganese is bleeding through into the fi nished water, it is time to add the pH Plus component to the fi ltration system. The amount of
material to add to a fi ltration system is as follows.

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 fi ltration system.
3) Disconnect the drain line and set aside.
4) Locate the connection nuts between the bypass and the control valve. Turn counter-clockwise
to loosen the nuts. Remove bypass from control valve. (See Figure 11).
5) Remove the control valve from the media tank by rotating the valve head assembly to the left
(counter-clockwise). When valve is detatched from threads of the tank, slowly lift the control
valve straight up and off the media tank. Do not rock the control from side to side as this
might damage the controller or distributor tube. Set aside to reassemble after media is loaded
into tank.
6) Using the funnel and centering device supplied with the unit originally, install over the dis-
tributor tube and inside the opening of the media tank to aid in adding the pH Plus material.
7) Using a 1/2” diameter fl exible tubing, siphon about 12” of water from the media tank to allow
for adding the pH Plus.
8) Pour the recommended amount of pH Plus into the fi lter media and add water back to fi lter to expel any air pockets in the media tank.
9) Remove funnel and centering tool. Clean the threads of the mineral tank to ensure no fi nes or media is trapped in them.
10) Reinstall the control valve back on top of media tank by placing the control valve on top of the tank and rotating the valve head assembly to the right
(clockwise) until it is hand tight and facing forward.
11) Connect both the bypass and the drain line to the control valve and hand tighten only the connection nuts.
12) Slowly open the inlet side of the bypass and pressurize the fi lter, check for leaks, correct if necessary.
13) Manually stage the control to backwash and clean the fi lter media of any fi nes 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.
14) Slowly open the outlet side of the bypass and pressurize the dwelling.
