POSI-CLEAR™ RP Cartridge Filter Installation and User’s Guide
THIS SYSTEM 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. 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.
b. Follow
Startup Instructions
exactly after completing service (page 3).
The air/pressure relief valve
must remain open until water comes out
, allowing all air out of the system.
2. Install lock ring properly.
a. Follow
Lock Ring Installation Instructions
exactly (page 3).
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.
AVOID DAMAGING SYSTEM
Never Exceed Maximum Pressure of Components.
The maximum working pressure of this filter is 50 psi. Never
subject this filter to higher pressure, even when conducting hydrostatic pressure tests. Pressures above 50 psi can damage your filter.
Be sure the maximum pressure of the filter system does not exceed the maximum pressure of any components within the system
(typically stated on each component), including during hydrostatic or external leak tests. Exceeding the maximum pressure of a
component can result in that component failing. If you do not know the pool or spa system operating pressure, install an ASME
approved automatic Pressure Relief or Pressure Regulator in the circulation system set to the lowest working pressure of any of the
components in the system.
Certain codes may require pressure testing the system. Performing pressure tests increases the risk of
component failure. Due to the potential risk that can be involved, keep the pressure test to the minimum time
required by the local code and take precautions. If pressure testing is necessary, follow these precautions:
1. Keep people away.
a. Do not allow people to work around the system when the circulation system is under pressure test.
Post appropriate warning signs and establish a barrier around the pressurized equipment. If the
equipment is located in an equipment room, lock the door and post a warning sign.
2. Never exceed maximum operating pressure.
a. When performing hydrostatic pressure tests or when testing for external leaks of the completed filtration
and plumbing system, ensure that the Maximum Pressure that the filtration system will be subjected
to does not exceed the maximum working pressure of any of the components contained within the
system.
