Section 1. Important Safety Instructions

1.1

Safety Instructions

MAXIMUM OPERATING PRESSURE OF THE FILTER IS 50 PSI.
NEVER SUBJECT THE FILTER TO ANY OPERATING PRESSURE EXCEEDING 50 PSI.
• Pressurized air in a system 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. Ensure that all air is out of the system before operating the equipment.
• Do not connect the system to an unregulated city water system or other external source of pressurized water producing pressures greater than 35 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.
• To minimize risk of severe injury or death, the filter and/or pump should not be subjected to the piping 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, locking devices 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 100º F (38º C).
• Limit test to 24 hours. After test, visually check system to be sure it is ready for operation.
NOTICE: These parameters apply only to Jandy equipment. For non-Jandy equipment, consult the equipment manufacturer.
To avoid electrical shock hazard, which can result in serious injury or death:
• Ensure that all electrical to the system is turned off before approaching, inspecting or troubleshooting any leaking valves or plumbing that may
have caused other electrical devices in the surrounding area to get wet.
• Water discharged from an improperly positioned filter or valve can create an electrical hazard which can cause death, serious injury or property damage.
• Improper dial valve installation can cause product failure or also cause the filter dial to be blown off, which can result in death, serious personal
injury or property damage.
• Never attempt to adjust or remove the dial valve when the pump is running or there is pressure in the system. this can cause product failure or
also cause the filter dial to be blown off, which can result in death, serious personal injury or property damage.
• Maintain your pressure gauge in good working order. The pressure gauge is the primary indicator of how the filter is operating.
• Creating high vacuum levels can cause the tank vessel to crack and leak with the potential for property damage.
• Be sure that all provisions for waste water disposal meet local, provincial or national codes. During any backwash or draining process, 100 gallons
or more of water will be discharged. Do not discharge water where it will cause flooding or damage.
• To avoid damaging the laterals (spokes), slowly add the filter media until the laterals are fully covered. Consult Installation and Operation Manual
for complete sand filling instructions. Cracked or broken laterals (spokes) will cause sand to be discharged to the pool.
• Use equipment only in a pool or spa installation.
• Before repositioning valve(s) and before beginning the assembly, disassembly, 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. (C) wait until all pressure is relieved (air will have stopped flowing from the air release valve).
• When installing the threaded lid follow Setup section, Install the Filter Lid in this manual.
• Once service on the circulation system is complete, follow the Startup And Operation section of this manual.
• 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. Use equipment only in a pool or spa installation.
