Follow these steps carefully to install the replacement filter head and clamp system.

1. Prepare the Filter System:
   • Turn off the pool pump and any automatic controls.
   • Close all valves leading to and from the filter to isolate it.
   • Open the air relief valve on the top of the filter to release any trapped air and pressure. Ensure the pressure gauge reads zero.
   • Open the filter drain plug to drain water from the filter tank.
2. Remove the Old Filter Head:
   • Once the filter is depressurized and drained, loosen the clamp system that secures the old filter head to the filter tank.
   • Carefully remove the old filter head and clamp. Inspect the filter tank's sealing surface for any debris or damage. Clean if necessary.
3. Install the New Filter Head and O-ring:
   • Inspect the new O-ring for any cuts or damage. Lightly lubricate the O-ring with a silicone-based lubricant specifically designed for pool equipment.
   • Place the lubricated O-ring into the groove on the filter tank or the new filter head, ensuring it is seated correctly and evenly.
   • Carefully position the new filter head onto the filter tank, aligning it properly.
4. Secure with the New Clamp System:
   • Place the new clamp system around the flange of the filter head and the filter tank.
   • Indsæt bolten gennem clamp ends and secure it with the nut and washer.
   • Spænd clamp bolt evenly and gradually using a wrench. Alternate tightening sides to ensure even pressure around the entire clamp. Do not overtighten, as this can damage the clamp or filter components. The clamp should be snug, holding the head firmly in place without excessive force.

   • Close the filter drain plug.
   • Open the valves leading to and from the filter.
   • With the air relief valve still open, turn on the pool pump.
   • Allow the filter tank to fill with water and air to escape through the air relief valve. Once a steady stream of water emerges from the air relief valve, close it.
   • Check for any leaks around the filter head and clamp system. If leaks are present, turn off the pump, relieve pressure, and re-tighten the clamp.
