THIS SYSTEM OPERATES UNDER HIGH PRESSURE
When any part of the circulating system, (e.g., closure, pump, lter, 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. Let air and pressure out of system before and after servicing.
a. Shut off pump and RELIEVE PRESSURE by opening the manual air/pressure relief valve before
servicing, including before tightening the clamp bolt. Follow the Opening the Filter, page 4
instructions exactly.
b. Follow the start-up instructions given Start-Up Instructions on page 6 exactly after completing
service. The air/pressure relief valve must remain open until water comes out, allowing all air out
of the system.
2. Install lid and clamp ring properly.
a. Follow the Installing the Filter Lid and Clamp Ring on page 5 instructions exactly. The nut must
be tightened until the spring is compressed when clamp is installed. Tap the clamp with a rubber
mallet or similar tool after clamp installation to ensure proper seating.
3. Maintain circulation system properly to help prevent air entering the system.
a. Replace worn or damaged parts immediately, (e.g., closure, pressure gauge, valve(s), O-rings, etc.).
b. Maintain proper water level in the pool or spa.
4. Verify that the return line to the pool is unobstructed. Ensure return valves are open and any winterizing
plugs are removed.
Your lter is a piece of machinery, do not tamper with it, attempt to disassemble it or otherwise adjust it unless you fully
understand it's operation. Serious injury or death can occur if the equipment is improperly handled. Consult a pool
service professional for maintenance and service assistance.
Always disconnect power to the pool circulating system at the circuit breaker before servicing the lter. Ensure that
the disconnected circuit is locked out or properly tagged so that it cannot be switched on while you are working on the
lter. Failure to do so could result in serious injury or death to serviceman, pool users or others due to electric shock.
