Installing The Filter Lid And Clamp Ring - Pentair FullFloXF 4000 Series Installation And User Manual

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
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 filter clamp together.
3. Insert the T-bolt through the other side of the clamp
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 to fit the clamp
properly.
c. Continue to tighten until the spring coils touch.
d. Tap around the entire clamp again and verify
the spring coils remain touching. If not,
continue to tighten the nut.
Note: The clamp is installed correctly only when the
spring coils remain touching after tapping the clamp
(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
