Push frother onto the motor shaft, making sure the flat in the frother lines up with the flat on the motor shaft. 19. Connect the red/black and green wires to the hopper switch, Fig.10 and install the hopper support panel using the four #8-32 screws. 20. Install whipper chamber on the whipper chamber receptacle by twisting counterclockwise until tabs on the whipper chamber lock with the tabs on the whipper chamber receptacle. Be sure dispense port is pointing down. 21. Install dispense tip into the bottom of the whipper chamber. 22. Slip the mixing chamber onto the mixing chamber water inlet tube far enough so the mixing chamber will seat inside the whipper chamber. 23. Install hopper assembly in the dispenser by sliding hopper assembly on the hopper support panel until the slot in the bottom rear of the hopper seats against the pin and retainer plates on the hopper support panel.
