Section 1. Safety Information

WARNING
FOR YOUR SAFETY: This product must be installed and serviced by a professional pool/spa service technician. The procedures in this instruction sheet must be followed exactly. Improper installation and/or operation may void the warranty.
WARNING
Ensure that all electrical power to the system is turned off before approaching, inspecting or troubleshooting any leaking valves that may have caused other electrical devices in the surrounding area to get wet. Failure to do so could result in an electrical hazard that could result in death or serious injury due to electrical shock, and may also cause damage to property.
WARNING

• Do not connect the system to an unregulated city water system or another external source of pressurized water producing pressures greater than 35 PSI.
• Pressurized air in the 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. Be sure all air is out of the system before operating or testing the equipment.

WARNING
To minimize the 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.
• AIR PRESSURE MUST NOT be used for pressure testing.
• Water pressure for the test must NOT EXCEED 35 PSI.
• Water temperature for the test must NOT EXCEED 100°F (38°C).
• Limit test to 24 hours. After the test, visually check the system to be sure it is ready for operation.

Notice: These parameters apply to Jandy equipment only. For non-Jandy equipment, consult the equipment manufacturer.

CAUTION
Never run the pump without water. Running the pump “dry” for any length of time can cause severe damage to both the pump and motor and may void the warranty.

WARNING
To avoid the risk of damage or injury, verify that all power is turned off before starting this procedure.
