Step 5

If media is already in the MEDIA TANK proceed to Step 6.

If media is shipped separately, follow these steps to center the distributor tube and load the fi lter media into the media tank to ensure the successful
installation of your MCA Series Iron Reduction System.

Remove the control valve by rotating the valve head assembly to the left or counter-clockwise and set aside to reassemble after media is loaded into
the tank.

Tilt media tank to a 45 degree angle until gravel shifts to the side of the tank and dimple at bottom of media tank is visible. This will allow you to place the
distributor tube basket assembly in the dimple on the bottom of the media tank.

Place media tank back in upright position and ensure gravel at the bottom of the media tank is level. Place centering tool on the distributor tube that is pro-
vided in the parts bag.

Locate the fi lter media that will be used in the iron reduction system and load into the media tank. Note: Never add media above line indicated on
side of tank. You may have received more media than required for the initial fi ll, save extra media for future replenishment. When fi nished adding
media, remove centering tool. Using a pail or garden hose slowly fi ll the media tank to the top to displace any air from the tank. Use a clean rag to
wipe the opening of the media tank to remove any dust or sediment before moving to the next step.

Place the control valve on top of the media tank. Engage the threads of the control valve into the threads of the media tank. Turn the valve clockwise
until it seats onto the media. Ensure a water tight seal by turning the valve another quarter turn.

CAUTION

To reduce the risk associated skin, eye, and respiratory tract irritation from gravel and fi lter media during installation:

• Gravel and several types of fi lter media may be used in this product, depending upon the application. During installation, dust may cause irritation to skin, eyes,

and respiratory tract.

• Utilize a NIOSH-approved dust fi lter mask, protective gloves, and appropriate eye protection when handling and pouring gravel and fi lter media.
• To request an MSDS relating to this product, call 203-238-8965 or go to www.3M.com , select country, and use the search engine to search MSDS. For emergen-

cies, call 800-364-3577 or 651-737-6501 (24 hours).

Step 6

Turn off the electrical source to the water well pump or the close the water shut off
valve on a municipal water supply to the dwelling once again. Depressurize the water
system by opening the nearest faucet to drain water from the water system in order to
allow the installation of the MCA Series Iron Reduction System.

Step 7

Determine location and cut the water line on the supply side of the pressure tank as
required to fi t the plumbing to the control valve connection fi ttings. You may want to in-
stall a separate three valve bypass prior to the control valve in case the supplied bypass
valve requires maintenance in order to provide undisturbed water use.

Step 8

Assemble and attach bypass valve to the control valve. See Figure 4 if needed. Make
certain the water enters inlet and discharges through the outlet side of the bypass
valve. Arrows can be viewed on the bypass valve to confi rm the correct fl ow path.
At this time make certain the bypass valve is in the bypass position and leave in that
position until instructed to place in the service position. Refer to Figure 4 for proper
operation.

CAUTION

To reduce the risk associated with property damage due to water leakage:

•

Do not

use torches or other heat sources near plastic plumbing, as damage may occur.

• Take care when using pliers or pipe wrenches to tighten plastic fi ttings, as damage may occur.
• On plastic fi ttings, use thread sealing tape only. Never use pipe sealant or pipe dope on plastic fi ttings, as damage may occur.

Step 9

Loosen set screw and pull out drain line fl ow control (DLFC) assembly from valve body (see Figure 4). Unscrew drain line elbow from DLFC. Apply PTFE
tape to threads. Reassemble to valve body, making certain DLFC assembly is fully inserted into valve body before tightening set screw.

Attach drain line to drain line fi tting. To prevent back pressure from reducing fl ow rate below minimum required for backwash, drain line must be sized
according to run length and relative height. Be careful not to bend fl exible drain tubing sharply enough to cause “kinking” (if kinking occurs drain line
MUST be replaced!).
