STEP 1: Unpack DF filter unit, making sure to remove entire contents of the shipping container prior to
disposal.
STEP 2: The filter should be installed after the pressure tank or water meter and before the water
heater.
STEP 3: If filter media is already in the media tank, proceed to step 4. If media is shipped separately,
remove the fill port cap by using the wrench provided turning it counter-clockwise. Remove the
top screen. Add media using a funnel. Do not overfill the tank. At least 14" of freeboard (empty
space) is required at the top of the media tank. More media may have been provided than
required for initial fill. Save any extra media for future replenishment. Clean any media out of
the fill port threads. Do not replace the fill port cap and screen yet.
STEP 4: Shut off water at main supply. Relieve pressure by opening nearest faucet. On private well
systems, turn off power to pump and drain pressure tank. SHUT OFF FUEL SUPPLY TO
WATER HEATER!
STEP 5: Attach bypass valve to the fill port head. Place the bypass in the BYPASS position by turning
the handles so they point at each other. Please see Figure 1 below.
STEP 6: Cut main supply line as required to fit plumbing to inlet and outlet of DF filter. Use the port
marked DOWNFLOW INLET for the incoming water line. Use the port marked UPFLOW
INLET for the outgoing water line. DO NOT apply heat to any fitting attached to bypass or
control valve.
STEP 7: Fill the media tank with water through the top of the fill port using a garden hose or bucket.
Replace the top screen and the fill port cap.
STEP 8: Turn on water at main supply.
STEP 9: Turn the bypass valve to the SERVICE position. See Figure 1 below. Check carefullyfor leaks.
