READ, UNDERSTAND, AND FOLLOW ALL SAFETY AND OPERATION INSTRUCTIONS.
FAILURE TO FOLLOW SAFETY AND OPERATION INSTRUCTIONS CAN RESULT IN SEVERE PERSONAL INJURY
OR DEATH.
CAUTION To reduce risk of injury, do not permit children to use or climb on this product. Closely
supervise children at all times. The ANSI/NSPI-4 Standard (above-ground and on-ground pools) advises
that components such as the filtration system, pumps, and heaters be positioned to prevent their being
used as a means of access to the pool by young children
.
WARNING COMPONENT SEPARATION HAZARD
Pool and spa water circulation systems operate under hazardous pressure during start up, normal
operation, and possibly after pump shut off. Pressure in system can cause explosive component
separation of the upper filter body if safety and operation instructions are not followed. Severe
personal injury or death can result.
This product should be installed and serviced only by a qualified pool professional.
TO AVOID COMPONENT SEPARATION
• Follow all safety and operation instructions.
• Do not operate water circulation system if a system component is assembled improperly, damaged,
missing, or not a genuine Hayward component.
• Before performing maintenance on the water circulation system, verify all system and pump controls
are in OFF position and filter manual air relief valve is in the OPEN position.
• Use ONLY Hayward clamp system components: DEX2421JKIT clamp assembly, DEX2421J2 nut/bolt
assembly, and a DEX2422Z2 metal reinforced seal.
Non-Hayward components may fail in use and cause explosive separation.
• Never rely on hand tightening the clamp nut to the clamp bolt. Using a ¾” socket on a torque wrench,
torque clamp nut and clamp bolt to 150 inch-lbs.
• Before starting system pump, insure filter manual air relief valve body is in LOCK position in filter
upper body.
• Before starting the system pump, verify that all system valves are set in a position to allow water from
the filter to return back to the pool.
• Before starting the system pump, the manual air relief valve must be in the OPEN position.
• When starting pump, do not stand over or near filter.
• If water leakage appears in the area of the filter tank clamp, immediately turn off all system circulation
pumps and electrical power. Do not return to the filter until all water flow has stopped. Reassemble
the clamp system per the instructions in this owner’s manual to stop the leak.
• Return to filter to close manual air relief valve only when a steady stream of water (Not air or air and
water mix) is discharged from the manual air relief valve.
• Do not change filter control valve position while system pump is running.
WARNING EXCESS PRESSURE HAZARD
Pressure testing of the pump and filter system in excess of the 50 PSI can cause explosive separation of
the components. Component separation can result in severe personal injury or death.
This is the safety-alert symbol. When you see this symbol on your equipment or in this manual, look for one of
the following signal words and be alert to the potential for personal injury or death.
WARNING Warns about hazards that could cause serious personal injury or, death, and or major property
