Releasing either ring with pressure on system will cause tank or tank head to blow off base, causing severe
injury or major property damage. NEVER adjust, tighten or loosen ring when tank is under pressure. If filter
leaks at the ring, do not adjust the ring. Instead, follow instructions under “Filter Disassembly”, below and
“Filter Assembly”, Page 8.
Hazardous Pressure
Regularly inspect clamp assemblies for cracked, corroded or broken welds and worn or stripped threads.
If any wear or damage shows, replace the complete ring.
!
Tension stresses and aggressive pool chemicals can aggravate mechanical wear. Tank clamp assemblies
and nuts or plastic knobs should be replaced every five years.
!
Do not use a filter that shows cracks, corrosion or distortion.
