Installation Notes
Turn off the pump and relieve system pressure. Remove the filter lid and lift out the element. Extract the old O-ring, clean the groove and lid flange of any debris or buildup. Lubricate the new CXFHR1001 O-ring with a pool-safe lubricant, seat it properly into the groove, replace lid and re-prime the system. Check for leaks upon restart.
Maintenance Tip
Inspect the O-ring each season for flattening, cracks or chemical damage. Replace if the lid begins to leak or the O-ring appears deformed—maintaining a tight seal helps ensure efficient filtration and longer cartridge life.
