Directions: To begin inflation open external stopper and pull to extend out. Attach adapter nozzle to the inflation end, insert pump and turn on. When fully inflated, push the valve in with the pump, sealing the internal stopper. Twist adapter, backing the pump out of valve while maintaining the seal. Fully remove pump and close external stopper. Valve should appear depressed into itself. Deflation: Remove adapter nozzle from inflation end and attach to the deflation end of pump.
