INITIAL SET-UP 1. Always turn off pump and relieve tank pressure by opening Air Relief Valve before loosening Center Clamp or servicing filter. WARNING-SEPARATION HAZARD Tighten nut until spring coils touch each other. 2. To re-assemble Clamp on filter, make sure Clamp is located and centered properly over the filter flange. If Clamp is tight, tap Clamp with rubber mallet or block of wood to help seat it.

When a steady stream of water emerges from the Air relief Valve, close Air Relief Valve. STARTING THE FILTER Close the filter drain and the vent valve. CAUTION All suction and discharge valves must be open when starting the pump. Failure to do so could cause severe personal injury and/or property damage. Prime and start the pump following the manufacturer's instructions. Air trapped in the system will automatically vent to the pool. When there is a steady flow of water returning to the pool, the filter is ready for precoating. DO NOT operate the filter for more than one minute without the precoat charge.
