Installing the Filter Lid and Clamp Ring
Follow these instructions exactly to prevent the lid from separating from the filter during system start-up
or operation. (See Important Warnings and Safety Instructions, page i-ii).
REQUIRED TOOLS:
• Ratchet Wrench
• 7/8" Socket
• Socket Extender (if needed)
• Rubber Mallet
PROCEDURE:
1. Ensure the O-ring is clean and in position in the lower
tank half. Press the FullFloXF
Style D.E. Filter lid onto the lower half so the O-ring fits
in between the tank halves.
2. Hold the ends of the clamp ring apart and place over
both upper and lower tank flanges. Bring the ends of
the clamp ring together.
3. Insert the T-bolt through the other side of the clamp
ring and hold together.
4. Place the small washer onto the T-bolt.
5. Place the spring, large washer and barrel nut onto the
T -bolt and tighten the nut by hand. Be sure the clamp
ring fits easily on the tank flanges.
6. After tightening by hand:
a. Use a 7/8 in. wrench (ratchet wrench
recommended) to tighten further.
b. Tap around the outside of the clamp ring with
a rubber mallet (or similar tool) multiple times
around the entire clamp ring to fit the clamp ring
properly.
c. Continue to tighten until the spring coils touch.
d. Tap around the entire clamp ring again and verify
the spring coils remain touching. If not, continue
to tighten the nut.
Note: The clamp ring is installed correctly only when
the spring coils remain touching after tapping the
clamp ring (See Figure 7).
7. Close the waste drain plug at the bottom of the filter.
8. Follow Start-Up Instructions exactly (see page 8).
DO NOT tighten the nut or attempt to adjust the clamp ring or lid while the system is turned on or under
pressure. This could cause the lid to separate from the filter
