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 5)
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 5)
⚠
WARNING
– 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
6) towards the ends of the clamp.
4. Never rely on hand tightening of clamp nut to clamp bolt.
Using a ¾ inch socket on a torque wrench, torque clamp nut
to clamp bolt to 17 Nm (150 inch-lbs). (Fig 1).
5. Follow Operation Instructions for "Starting the Pump and
Filter System"
VACUUMING
Vacuuming can be performed directly into the filter whenever
needed. Backwash filter after vacuuming, if required.
REMOVING THE MANUAL AIR RELIEF VALVE
Your Filter comes with a Manual Air Relief Valve (MAR) pre-installed from the factory.
For Qualified pool professionals only: If MAR valve needs to be serviced, follow these instructions carefully.
1. Turn off all system circulation pumps and all electric power on the pad.
2. Set all system valves in a position to prevent water from flowing to the filter.
3. The manual air relief valve must be placed in the OPEN position.
4. Wait until all water leakage has stopped.
5. Grasp the MAR body at the flats, turn the MAR counterclockwise until the indicator on the on the MAR flange is aligned
with the "UNLOCK" position on the upper filter body.
6. Pull straight up to remove the MAR, a slight rocking motion may help.
