EQUIPMENT INFORMATION RECORD

Section 1. Important Safety Instructions

READ AND FOLLOW ALL INSTRUCTIONS

WARNING

MAXIMUM OPERATING PRESSURE OF THE FILTER IS 35 PSI.
NEVER SUBJECT THE FILTER TO ANY OPERATING PRESSURE EXCEEDING 35 PSI

• 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.
• Pressurized air in a system can cause product failure or also cause the dial valve to be blown off which can result in death, serious personal injury or property damage.
• 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 lter 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 lter 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 lter dial to be blown off, which can result in death, serious personal injury or property damage.

CAUTION

• Maintain your pressure gauge in good working order. The pressure gauge is the primary indicator of how the filter is operating.
• Creating high vacuiffll 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), slovdy add the filter media until the laterals are fully covered. Consult Installation and Operatm Manual for complete sand filling instructions Cracked or broken laterals (spokes) will cause  sand to be discharged to the pool.

All plumbing connections should be in accordance with local plumbing and building codes. Do not use pipe joint compound, glue or solvent on the union nut threads.

5.1 Filter Valve Functions
Filter pump must be turned off prior to making any adjustments to the multiport valve. When starting the pump after making adjustments to the valve be sure to stand clear of the filter. Ensure that all provisions for waste water disposal meet local, state or national codes. Set Valve Handle to:

• FILTER: Water passes through filter sand and returns back to the pool. Set for Normal filtration operation. Multiport Valve should be in this position for all typical filtration and sanitation circulation.
• WASTE: Water bypasses filter sand and is routed to waste port.
• RECIRCULATE: Water bypasses filter sand and is returned to the pool.
• CLOSED: Closes all passages through the Multiport Valve.
• WINTER: This valve position leaves the multiport valve handle disengaged and all passages through the valve open for draining. Once the filter is drained, it is recommended that the valve handle be kept in the Winter position.
• BACKWASH: Water passes through filter sand in reverse and is sent to the waste port. With pump running, periodically check water clarity in sight glass. Once water is visably clear, the backwash cycle is complete.
• RINSE: Water passes through filter sand to waste. Use after backwash cycle to clean debris from the Multiport Valve. Rinse should run for 1-2 minutes.

5.2 Initial Startup

1. Make sure that all connections are secure and that any glued piping connections or joints have had sufficient time to cure.

2. Backwash filter sand.
   • Set multiport valve to backwash.

3. Turn on filter pump.
   • Water will discharge from waste port.
   • While pump is running, periodically check the water clarity through the sight glass or at the waste port.
   • Once water is visibly clear the backwash cycle is complete.
   • See Section 5.1, Filter Valve Functions for details.

4. Turn off filter pump.

5. Set valve to rinse.

6. Stand clear of filter and turn on the filter pump.
   • Water will discharge from waste port.

7. Allow filter to run for 1-2 minutes.

8. Turn off filter pump.

9. Set multiport valve to filter.
