DETAILED SPECIFICATIONS
Design and Construction
USN72 is a fully-automatic dishwashing
machine constructed entirely of heavy-gauge
stainless steel. The stainless steel angle frame
provides a rigid, heavy-duty support for internal
components, tank and hood, enhancing the
reliability and extending the service life of the
machine.The tank and hood are of water-tight,
single-unit construction. The leak-proof
internally-mounted front door permits easy
access to the tank for cleaning. Perforated
stainless steel refuse screens and pump intake
strainer are easy to remove and clean.
Pump and Motor
The wash pump and rinse pump provide high-
pressure recirculating spray. The 2-hp pump
motor is wired through a magnetic contactor
and has thermal overload protection. Pump and
motor are mounted directly to the frame.
Spray System
Upper and lower wash spray arms distribute
high pressure “water knife” cleaning action
across every surface of the wares. 180°F
sanitizing spray is delivered through upper and
lower final rinse spray arms.
Rinse Saver
The standard rinse saver is comprised of a
magnetic switch which activates the final rinse
only when wares are present in the final rinse
area.
Tank Heating and Filling System
The machine has a manual fill and sight glass for
each tank. Proper tank temperature is main-
tained by thermostatically controlled electric
tank heat, or steam heat with positive low-water
protection.
Fully-automatic Operation
The “start” button starts the conveyor and
establishes control voltage to the pump motor,
rinse saver.
Rack Conveyor
The rack conveyor is stainless steel chain and
has rear lugs to prevent rack slippage. It is
driven by a 1/4-hp motor and uses 20" x 20"
racks.
Due to an ongoing value analysis program at
Champion, specifications contained in this catalog
are subject to change without notice.
Warning:
Plumbing and electrical connections
should be made by qualified workmen
who will observe all the applicable
plumbing, sanitary, safety and the
National Electrical Codes.
Plumbing Notes:
Because of the variation in house-supplied
water pressure, water pressure regulating
valve (PRV) may be needed (water PRV is
standard on machines with booster). The PRV
can either be purchased from Champion or
obtained locally.
Venting Notes:
Fabricated duct size: 11.88" x 3.88"
