Section 1. Safety Information
1.1 Important Safety Warning
NEVER OPERATE OR TEST THE FIL TER SYSTEM AT MORE THAN 50 PSI.
THIS FILTER OPERATES UNDER HIGH PRESSURE. WHEN ANY PART OF THE
CIRCULATING SYSTEM, i.e., FILTER, PUMP, VALVE(S), CLAMP, ETC. IS SERVICED,
AIR CAN ENTER THE SYSTEM AND BECOME PRESSURIZED WHEN THE SYSTEM IS
RESTARTED. PRESSURIZED AIR CAN CAUSE THE FILTER LID TO BE BLOWN OFF
WHICH CAN RESULT IN DEATH, SERIOUS PERSONAL INJURY OR PROPERTY DAMAGE.
TO AVOID THIS PO TEN TIAL HAZ ARD, FOL LOW ALL OF THE IN STRUC TIONS IN THIS
MAN U AL.
WARNING
1.2 General Safety Instructions
ATTENTION INSTALLER:
This manual contains important information about the installation, operation and safe use of this
product. This information should be given to the owner/operator of this equip ment.
1. Before repositioning valve(s) and before beginning the assembly, disassembly, or adjustment of the clamp, or
any other service of the circulating system; (A) turn the pump off and shut off any automatic controls to ensure
the system is not inadvertently started during servicing; (B) open the air release valve; (C) wait until all pressure
is relieved (air will have stopped flowing from the air release valve).
2. Whenever installing the filter clamp follow Section 3.4 of this manual, "Locking Ring Installation".
3. Once service on the circulation system is complete, follow Section 4 of this manual, "Start-up and
Operation".
4. Maintain circulation system properly. Replace worn or damaged parts immediately.
5. Be sure that the filter is properly mounted and positioned according to these installation instructions.
6. Do not pressure test above 50 PSI. Pressure testing must be done by a trained pool professional.
SAVE THESE INSTRUCTIONS.

Section 2. General Information
2.1 Introduction
This manual contains information for the proper installation and operation of the Jandy® CJ Cartridge Filters.
Procedures in this manual must be followed exactly.
To obtain additional copies of this manual contact us
at 707.776.8200 ext. 237. For address information see
back cover.
2.2 Description
Cartridge filters do not require sand or diatomaceous
earth as the filter medium. Instead they contain a filter
cartridge element which is easily removed for cleaning
or replacement.
Dirty water flows into the filter tank and is directed
through the filter cartridge. The debris is collected on
the surface of the cartridge as the water flows through
it. The water will travel through the central filter core
towards the bottom of the filter into the lower manifold.
Clean water is returned to the swimming pool through
the filter outlet port at the tank's bottom.
As debris collects in the filter, the pressure will rise
and water flow to the pool will diminish. The filter will
eventually become so plugged with debris that it will be
necessary to remove the filter cartridge and clean it (see
Section 6 "Cleaning the Filter").
NOTE A filter removes dirt and other suspended particles
but does not sanitize the pool. Pool water must be
sanitized and chemically balanced for clear water.
The filtration system should be designed to meet
local health codes. At a minimum, the system should
turnover the total volume of water in your pool two to
four times in a 24 hour period.
5. Use barrel unions to connect each component of
the water conditioning system for future servicing.
All Jandy filters come with these type of fittings.
WARNING
The maximum working pressure for this filter is 50
psi. Never subject the filter to pressure exceeding 50
psi, even when conducting hydrostatic pressure tests.
Pressures above 50 psi can cause the lid to be blown
off.
6. When performing hydrostatic pressure tests or
when testing for external leaks of the completed
filtration and plumbing system, ensure that
the maximum pressure the filtration system is
subjected to does not exceed the maximum
working pressure of any of the components
within the system.

2.3 General Requirements
1. For best overall performance place the system as
close to the pool as possible.
2. The filter should be located on a level concrete
slab so that the orientation of the valve outlets and
the pressure gauge are convenient and accessible
for the installation and operation of the unit.
3. Protect the filter from the weather.
4. If fitting a chlorinator and/or any other device into
the filtration plumbing circuit, great care must be
xercised to ensure that the appliance is installed in
accordance with the Manufacturer’s Instructions
and any standards that may exist.
