WARNING
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 inch socket on a torque
wrench, torque clamp nut and clamp bolt to 17 Nm (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.
