BODY AND CLAMP RE-ASSEMBLY
1. Place the metal reinforced seal on the lower filter body (Fig 4).
Place the upper filter body on the Hayward DEX2422Z2 metal
reinforced seal and lower filter body in a position which allows
all operation and safety labels to be clearly visible and the upper
body to be centered on the lower filter body. Press down firmly
and evenly to set the upper filter body. (Fig 7)
2. Replace the filter clamp around the upper and lower filter
bodies. Hold the clamp ends to position the clamp on the filter
bodies with the clamp ends adjacent to the safety and operation
labels on the filter bodies. (Fig 7)
DO NOT HIT OR STRIKE CLAMP WITH HAMMER OR
METAL TOOLS.
3. Insert clamp bolt through the clamp ends and thread the clamp
nut onto clamp bolt with rounded end of the nut (Fig 8) towards
the ends of the clamp.
4. Never rely on hand tightening of clamp nut to clamp bolt.
Using a ¾" socket on a torque wrench, torque clamp nut to
clamp bolt to 150 inch-lbs. (Fig 9).
5. Follow Operation Instructions for "Starting the Pump and Filter
System" (Page 5).
