There is an indentation in the bottom of the tank that will allow the distributor tube to be centered. A flashlight may be needed to verify the tube is in the center of the tank.
Pour it evenly around the hole to ensure it is well distributed in the tank and pour slow enough to keep from plugging the hole. A helper may be needed to hold the funnel during the filling process.
NOTE: It is recommended that a dust mask and safety goggles be worn to prevent possible injury.
Remove the funnel and cap from the distributor tube.
Place the upper basket over the distributor tube and push the valve onto the tank. Thread the valve on the tank by turning it clockwise. Be sure not to cross thread the valve on the tank.
DO NOT use tools to tighten the valve or damage could occur.
