WARNING — THIS FILTER OPERATES UNDER HIGH PRESSURE
When any part of the circulating system, (e.g., closure, pump, filter, valve(s), etc.), is serviced, air can enter the system and become
pressurized. Pressurized air can cause the top closure to separate which can result in severe injury, death, or property damage.
To avoid this potential hazard, follow these instructions:
1. If you are not familiar with your pool filtering system and/or heater:
2. Before repositioning valve(s) and before beginning the assembly, disassembly, or any other service of the circulating system:
3. Whenever installing the filter closure FOLLOW THE FILTER CLOSURE WARNINGS EXACTLY.
4. Once service on the circulating system is complete FOLLOW INITIAL START-UP INSTRUCTIONS EXACTLY.
5. Maintain circulation system properly. Replace worn or damaged parts immediately, (e.g., closure, pressure gauge, valve(s),
6. Be sure that the filter is properly mounted and positioned according to instructions provided.
Note: Turn off power to unit prior to attempting service or repair.
