Maintenance - 3M APIF100 Installation And Operating Instructions Manual

Apif series resdential iron reduction systems

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.

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.

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".
