SECTION 8: MAINTENANCE
Depending on your water quality, it may be necessary to perform maintenance on your fi lter system in order to ensure continued performance. This is to both low
pH, high manganese and 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 lter will need
to be serviced. To correct this condition, it will be necessary to add MPH adder to the fi lter bed. The part number is MPH04, and can be purchased as a single unit
or in a case of 6, which is MPH0406. Either of these items can be purchased through our wholesale chain in your area. MPH0406 is a 3 ½ pound jar of pH boost-
ing 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 a quarter. When Iron is the only problem, a water pH needs to be 7.2 higher. When Man-
ganese 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 Inc.. 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 MPH adder component to the fi lter. The amount of material to add to a fi lter is as follows.
Standard bed fi lters (identifi ed by an “S” in the model number, i.e. APIF100S or no “S”, i.e. APIF100)
1- 3 ½ pound jar of MPH adder for each cubic foot of fi lter material
Manganese bed fi lters (Identifi ed by an “M” in the model number, i.e APIF100M)
2- 3 ½ pound jars of MPH adder for each cubic foot of fi lter material.

Step by step procedure to add MPH adder 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 fi gure 3 in section 3 for proper orientation.
2) Manual initiate a backwash cycle to relieve water pressure from the inside of the fi lter.
3) Disconnect the drain line and set aside.
4) Remove the latch on the clamp assembly and separate the clamp assembly. Set aside in a secure location for reuse.
5) Slowly lift the control valve straight up and off the fi lter vessel. Do not rock the control from side to side as this might damage the controller or distributor
tube.
6) Using the funnel and centering device supplied with the unit originally, install over the distributor tube and inside the opening of the fi lter vessel to aid in add-
ing the MPH adder material.
7) Using a ½ diameter fl exible tubing siphon about 12” of water from the fi lter vessel to allow for adding the MPH adder.
8)
Pour the recommended amount of MPH adder into the fi lter media and add water back to fi lter to expel any air pockets in the fi lter vessel.
9)
Reinstall the control valve back on top of fi lter vessel. You may want to apply some silicone lubricant to the O-rings, distributor tube and the inside of the
fi lter vessel opening to facilitate for easier installation. Allow the control valve to rest on the fi lter vessel fl ange and with one steady downward motion push
the control into the vessel opening to seat properly. Manually stage control valve to the service position. Refer to Page 3-8, “HOW TO MANUALLY INITIATE
IMMEDIATE REGENERATION”.
10) Reinstall the clamp assembly around both the control valve and fi lter vessel fl ange and secure the latch. See Figure 7 for proper orientation in on page 3-12.
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) Slowly open the outlet side of the bypass and pressurize the dwelling.
14) Manual stage the control to backwash and clean the fi lter media of any fi nes that would be present till clear. Allow the control to complete regeneration cycle
completely and return to service. Refer to page 3-8, “HOW TO MANUALLY INITIATE IMMEDIATE REGENERATION”.
