AM SELECT TALL
DISHWASHER
The microcomputer-based control system is built into the
AM Select dishwasher. It is available in standard electrical
specications of 208-240/60/1, 208-240/60/3, 480/60/3,
200-240/50/3, 380-415/50/3 and is equipped with a reduced
voltage pilot circuit transformer.
*CAUTION: CERTAIN MATERIALS, INCLUDING SILVER,
ALUMINUM AND PEWTER ARE ATTACKED BY SODIUM
HYPOCHLORITE (LIQUID BLEACH) IN THE CHEMICAL
SANITIZING DISHWASHER MODE OF OPERATION. WATER
HARDNESS MUST BE CONTROLLED TO 4-6 GRAINS FOR
BEST RESULTS.
CONSTRUCTION: Drawn tank, tank shelf and feet constructed
of 16 gauge stainless steel. Wash chamber and front trim panel
above motor compartment are polished, satin nish. Frame is
12 gauge stainless steel, chamber is 18 gauge, and removable
trim panels are 20 gauge.
CHAMBER: Stainless steel chamber with large 20
3
⁄4" W x 27" H
opening will accommodate 18" x 26" sheet pans or a 60-quart
mixing bowl.
CHAMBER LIFT: Chamber coupled by stainless steel handle,
spring counterbalanced. Chamber guided for ease of operation
and long life.
PUMP: With stainless steel pump and impeller, integral with
motor assures alignment and quiet operation. Pump shaft seal
with stainless steel parts and a carbon ceramic sealing interface.
Easily removable impeller housing permits ease of inspection.
Capacity 160 GPM. Pump is completely self-draining.
MOTOR: Built for Hobart, 2 H.P., with inherent thermal
protection, grease-packed ball bearings, splash-proof design,
ventilated. Single-phase is capacitor-start, induction-run type.
Three-phase is squirrel-cage, induction type.
MICROCOMPUTER CONTROL SYSTEM: Hobart micro-
computer controls, assembled within water-resistant enclosure,
provide built-in performance and reliability.
The microcomputer control, relays and contactors are housed
behind a stainless steel enclosure, hinged to provide easy
access for servicing. The line voltage electrical components are
completely wired with 105°C, 600V thermoplastic insulated wire
with stranded conductors and routed through listed electrical
conduit. Electrical components are wired with type ST cord.
Line disconnect switch NOT furnished.
CYCLE OPERATION: The microcomputer-timing program is
started by closing the doors, which actuates the door cycle
switch. The microcomputer energizes the wash pump motor
contactor during the wash portion of the program. After the
wash, a dwell permits the upper wash manifold to drain. At the
end of the dwell, the nal rinse solenoid valve is energized.
After the nal rinse valve closes, Sani-Dwell (Hot Water Mode
only) permits sanitization to continue. The Rinse display remains
on during this period, completing the program. If the micro-
computer is interrupted during a cycle by the door-cycle switch,
the microcomputer is reset to the beginning of the program.
Hot Water Sanitizing (58 racks per hour) – 57 seconds: 38
Second Wash, 2 Second Dwell, 10 Second Rinse, 7 Second
Sani-Dwell. Chemical Sanitizing (65 racks per hour) – 50
Seconds: 38 Second Wash, 2 Second Dwell, 10 Second Rinse.
Other programs can be pre-selected by your Hobart service
technician.
Manual wash cycle selector also provides selection of 2-, 4- or
6-minute wash cycles for heavier washing applications.
WASH: Hobart revolving stainless steel wash arms with
unrestricted openings above and below provide thorough
distribution of water jets to all dishware surfaces. Arms are easily
removable for cleaning and are interchangeable. Stainless steel
tubing manifold connects upper and lower spray system.
RINSE: Rotating rinse arms, both upper and lower, feature
14 rinse nozzles. The stainless steel upper and lower rinse arms
are easily removable without tools for inspection and are
interchangeable. Diaphragm-type rinse control solenoid valve
mounted outside machine. Machine is equipped with special hot
water vacuum breaker on downstream side of rinse valve –
mounted 6" above uppermost rinse opening. Easy open brass
line strainer furnished.
FILL: Microcomputer controlled ll valve installed on upstream
side of rinse vacuum breaker. Ratio ll method is used giving the
correct ll at any owing water pressure. (20 PSIG minimum
necessary for proper rinsing.)
DRAIN AND OVERFLOW: Large bell type automatic overow
and drain valve controlled from inside of machine. Drain
automatically closed by lowering chamber. Drain seal is large
diameter, high temperature “O” ring. Cover for overow is
integral part of the stand pipe.
STRAINER SYSTEM: Equipped with large, exclusive self-
ushing, easily removable perforated stainless steel, one-piece
strainer and large capacity scrap basket. Submerged scrap
basket minimizes frequent removal and cleaning.
HEATING EQUIPMENT: Standard tank heat is 5KW electric
immersion heating element. Regulated power infrared gas
immersion tube system is optional at extra cost. A solid-state
igniter board controls the gas valve and provides ame ignition.
A transformer steps the control circuit voltage down to 24 volts
to power the igniter board and gas valves.
Gas Heated Dishwasher: For natural gas, gas pressure
(customer connection) not to exceed 7" W.C. For liqueed
petroleum, gas pressure to burner (customer connection) not to
exceed 11" W.C. If gas pressure is higher than 7" W.C. natural or
11" W.C. LP, a pressure regulating valve must be supplied (by
others) in the gas line to the dishwasher. Water temperature
regulation is controlled by thermistor sensor in combination with
microcomputer controls. The tank heat and positive low water
protection microcomputer circuits are automatically activated
when the main power switch is turned “on”. If tank is accidentally
drained, low water protection device automatically turns heat
off. Gas immersion tube is additionally protected by a high limit
device mounted on the surface of the tube. These features are
standard with the Hobart Microcomputer Control System.
OPTIONAL EQUIPMENT AT EXTRA COST – ELECTRIC
BOOSTER HEATER: Electric booster with Sense-A-Temp
TM
technology adequately sized to raise 110°F inlet water to 180°F
(not available on gas heat machines).
ACCESSORIES: 19

cycle audible alarm (eld activated). Delime notication (eld
activated). Desirable functional accessories can be furnished
at added cost. See listed options and accessories on this
