Troubleshooting
Use the following troubleshooting information to resolve possible problems with your filter.
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 filtering system:
a. Do NOT attempt to adjust or service without consulting your dealer, or a qualified
technician.
b. Read the entire Installation & User’s Guide before attempting to use, service or adjust the
filtering system.
2. Before repositioning valve(s) and before beginning the assembly, disassembly, or any other
service of the filter 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
bleeder valve; (C) wait until all pressure is relieved.
3. Whenever installing the filter closure FOLLOW THE FILTER CLOSURE WARNINGS EXACTLY.
4. Once service on the irrigation system is complete FOLLOW INITIAL START-UP INSTRUCTIONS
EXACTLY.
5. Maintain irrigation system properly. Replace worn or damaged parts immediately, (e.g., closure,
pressure gauge, valve(s), o-rings, etc.).
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.
