Important Safety Warnings
• Do not connect system to an unregulated city water system or other external source of pressurized
water producing pressures greater than 35 PSI.
• Pressurized air in system can cause product failure or also cause the ﬁ lter lid to be blown off which
can result in death, serious personal injury, or property damage. Be sure all air is out of system
before operating or testing the equipment.
MAXIMUM OPERATING PRESSURE OF THE FILTER IS 50 PSI. NEVER SUBJECT THE FILTER
TO ANY OPERATING PRESSURE EXCEEDING 50 PSI.
This filter operates under high pressure. When any part of the circulating system, i.e., filter, pump,
valve(s), etc. is serviced, air can enter the system and become pressurized when the system is
restarted. Pressurized air can cause product failure or also 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.
To minimize risk of severe injury or death the filter and/or pump should not be subjected to the piping
system pressurization test.
Local codes may require the pool piping system to be subjected to a pressure test. These
requirements are generally not intended to apply to the pool equipment such as filters or pumps.
Jandy pool equipment is pressure tested at the factory.
If however this WARNING cannot be followed and pressure testing of the piping system must include
the filter and/or pump BE SURE TO COMPLY WITH THE FOLLOWING SAFETY INSTRUCTIONS:
• Check all clamps, bolts, lids, lock rings and system accessories to ensure they are properly
installed and secured before testing.
• RELEASE ALL AIR in the system before testing.
• Water pressure for test must NOT EXCEED 35 PSI.
• Water temperature for test must NOT EXCEED 100°F (38°C).
• Limit test to 24 hours. After test, visually check system to be sure it is ready for operation.
Notice: These parameters apply to Jandy equipment only. For non-Jandy equipment, consult equipment manufacturer.
1.2 General Safety Instructions
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.
Use equipment only in a pool or spa installation.
Before repositioning valve(s) and before beginning the assembly, disassembly, or removal or adjustment of the
lid, 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; and (C) wait until
all pressure is relieved (air will have stopped flowing from the air release valve).
Whenever installing the threaded lid follow Section 3.7 of this manual, "Lid Installation".
Once service on the circulation system is complete, follow Section 4 of this manual, "Start-up and Operation".
Maintain circulation system properly. Replace worn or damaged parts immediately.
Be sure that the filter is properly mounted and positioned according to these installation instructions.
Do not pressure test above 35 PSI. Pressure testing must be done by a trained pool professional.
