instructions may result in serious injury.
1. Make sure clamp is located and centered properly over the filter flange.
2. Both sides of the clamp must be tightened firmly and evenly until spring coils touch each other (see illustration
below).
3. Final space between both clamp halves should be equal.
The following sleeve nut assembly, which includes a spring, two (2) washers (small and large hole) and a sleeve nut,
provides a visual means of ensuring that the clamp is tight.
Before Starting the Filter System
1. Obtain a supply of operating chemicals, D.E., and a pool test kit. Use only the swimming pool grades of D.E.,
such as:
CELATOM (Eagle-Picher Industries, Inc.)
AQUA-CEL (Johns-Manville Products Corporation)
DICALITE 4200 (Grefco, Inc.)
WITCO (Witco Corporation)
2. Superchlorinate the pool water by adding unstabilized granular or liquid chlorine. Stabilized forms of chlorine
are recommended for normal daily use after the initial clean up of the water. Follow chemical manufacturer's
recommendations for superchlorination and daily use.
Start-Up & Operation

Starting the Filter

Close the filter drain and the vent valve.
CAUTION
Failure to do so could cause severe personal injury and/or property damage.
1. Prime and start the pump following the manufacturer's instructions.
2. Air trapped in the system will automatically vent to the pool. Once air has escaped the filter and a steady
stream of water is returning to the pool, the filter is ready for pre-coating. DO NOT operate the filter for
more than one (1) minute without the pre-coat charge.
– All suction and outlet valves MUST be OPEN before operating the filter system.
