N-8 DISPOSER
DESIGN AND CONSTRUCTION
• Waste chamber design permits dual directional operation when used with reversing control or switch, doubling the life
cycle of the shattering mechanism. Regular waste chamber available with either 4 1/2” or 7” throat size.
• Basic body components are cast gray iron, machined, primed and painted. 8” diameter rotor with (2) bolt-on
reversible impact bars and sizing ring are cast ductile iron, machined, balanced and heat treated.
• Flexible drain connector. Fastens quickly to either metal or PVC drain line (2” pipe size).
• Stainless steel legs and feet, adjustable from 0” to 2”.
• Disposer connects to cone or sink assembly by means of a neoprene isolation sleeve and (2) stainless steel clamps.
• Offset Design: For maximum space utilization, disposer is also available with an 8” off-set waste chamber for both
cone and sink attachments. (Available with 7” diameter throat size only.)
MOTOR
• Reversing, continuous duty, 1725 RPM (1425 RPM, 50 Hz), full rated horsepower, double sealed, permanently
lubricated ball bearings.
• Thermal overload protection with manual reset button.
• Available for single phase or three phase installations.
• Available in 1 1/2 HP for light waste, 2 HP for standard use, 3 HP for heavy duty use.
• Dual voltage windings allow multi-voltage operation by motor lead connection. (See motor wiring diagram)
115-230 Volts, 60Hz; 110/220 Volts, 50 Hz, 1 Phase
208-230/460 Volts, 60 Hz; 190-220/380-440 Volts, 50 Hz, 3 Phase
(See table for ampere draw per horsepower, volts & phase)
