FILTER OPERATES UNDER HIGH PRESSURE.
When any part of the circulating system, (e.g., clamp, pump, filter, valve(s), etc.), is serviced, air can enter the system and become
pressurized. Pressurized air can cause the lid to separate which can result in severe injury, death, or property damage.
To avoid this potential hazard, follow these instructions:
1. Before repositioning valve(s) and before beginning the assembly, disassembly, or adjustment of the clamp or any other
service of the circulating system: (A) Turn the pump OFF and shut OFF any automatic controls to ensure the system is NOT
inadvertently started during the servicing; (B) open the manual air relief valve; (C) stand clear of the filter; (D) wait until all
pressure is relieved.
2. Whenever installing the filter clamp FOLLOW THE CLAMP INSTALLATION INSTRUCTIONS EXACTLY.
3. Once service on the circulating system is complete FOLLOW SYSTEM RESTART INSTRUCTIONS EXACTLY.
4. Maintain circulation system properly. Replace worn or damaged parts immediately, (e.g., clamp, pressure gauge, valve(s),
o-rings, etc).
5. Be sure that the filter is properly mounted and positioned according to instructions provided.
