AFWFilters 5600 Series Installation Instructions Manual page 6

When filling the tank, do so slowly and ensure the
riser tube stays correctly positioned and centered in
the tank. If you have more than one bag of resin the
order does not matter and all of it should be used.
Once all the resin is loaded the tank will not be com-
pletely full, this is normal.
Step 2d: Finish filling tank with water -Optional-
Once the resin is loaded and your tank is positioned you may finish filling the tank with wa-
ter. This can help reduce air bubbles and ease initial startup.
Section 3: Attach the Control Head
Step 3a: Lubricate the O-rings
The tank O-ring (Img Left) seals the control valve to the tank, and the pilot O-ring (Img Right)
seals around the riser tube. Verify they are present and free
from nicks or kinks. Use a silicone lubricant or vegetable oil
to both O-rings. It is also recommended to verify that the
riser tube fits snugly into the pilot hole and that the O-ring
seals around it.
Step 3b: If Present - Inspect and install the top distributor
basket
Depending on system configuration your system may include a top distributor basket (Img
Left). If your system includes one it is recommended that
you use it. If you do not have one then it is not needed. If
you do have one the larger end will fit inside the bottom
of your control valve, with the smaller end sliding over the
riser tube pointing down into the tank (Img Right). Please
note that locking tabs hold it in place so a fair amount of
force is needed to install or remove it.
Step 3c: Screw on control head
Ensure the riser tube slips inside the pilot opening in the bottom of the head. Screw the head
down onto the resin tank until solid contact is made
between the tank and O-ring, then tighten about
another 1/4–1/3 of a turn and STOP. Once properly
tightened down check to ensure the tank and control
head meet evenly all the way around.
If you have KDF media (heavy
gold or brown media) it will be
added to the top of the tank.
DO NOT use Teflon tape or other
sealants on the threads between
the tank and valve. Hand tighten
only.
