5. Begin to tighten nut using a 7/8" wrench. Then tap around the outside of the filter clamp with a
mallet (or similar tool) to insure uniform loading and proper seating of the clamp. Continue tapping
and tightening until the spring coils touch each other. Do not tighten beyond this point.
6. Follow the procedures in Section C, System Restart Instructions.
7. The spring coils should be checked at least once per month to ensure that they continue to touch
each other, indicating that the clamp is under sufficient tension. If coils fail to touch repeat Step
B.5 in this section, above.
C. SYSTEM RESTART INSTRUCTIONS
THIS FILTER OPERATES UNDER HIGH PRESSURE. WHEN ANY PART OF THE
CIRCULATING SYSTEM (e.g., CLAMP, PUMP, FILTER, VALVES, ETC.) IS SERVICED, AIR CAN
ENTER THE SYSTEM AND BECOME PRESSURIZED. PRESSURIZED AIR CAN CAUSE THE
LID TO BE BLOWN OFF WHICH CAN RESULT IN SEVERE INJURY, DEATH, OR PROPERTY
DAMAGE. TO AVOID THIS POTENTIAL HAZARD, FOLLOW THESE INSTRUCTIONS.
1.
Open the High Flow™ manual air relief valve until it snaps into the full open position (this
only requires a quarter turn counter-clockwise). Opening this valve rapidly releases air
trapped in the filter.
2. Stand clear of the filter tank, then start the pump.
3. Close the High Flow™ manual air relief valve after a steady stream of water appears.
4. The system is not working properly if either of the following conditions occur.
a. A solid stream of water does not appear within 30 seconds after the pump's inlet basket fills
with water.
b. The pressure gauge indicates pressure before water outflow appears.
If either condition exists, shut off the pump immediately, open valves in the water return line
to relieve pressure, and clean the air relief valve, see Section F, Cleaning the High Flow™
manual air relief valve. If the problem persists, call (800) 831-7133 for assistance.
D. CLEANING FILTER MANUALLY
Operating the filter system without filter internal components installed can allow air to
accumulate within the filter. Pressurized air can cause the lid to blow off which can result in
severe injury, death or property damage. Always operate filter system with filter internal
components installed.
The following information should be read carefully since it outlines the proper manner of care and operation for
your filter system. As a result of following these instructions and taking the necessary preventative care, you can
expect maximum efficiency and life from your filtration system.
