F-40079 – AM Select Tall Dishwasher
As continued product improvement is a policy of Hobart, specifications are subject to change without notice.
AM SELECT TALL
DISHWASHER
The microcomputer-based control system is built into the  
AM Select dishwasher. It is available in standard electrical 
specifications 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 finish. Frame is  
12 gauge stainless steel, chamber is 18 gauge, and removable 
trim panels are 20 gauge.
CHAMBER: Stainless steel chamber with large 20

" 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 final rinse solenoid valve is energized.  
After the final 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 fill valve installed on upstream 
side of rinse vacuum breaker. Ratio fill method is used giving the  
correct fill at any flowing water pressure. (20 PSIG minimum 
necessary for proper rinsing.)
DRAIN AND OVERFLOW: Large bell type automatic overflow 
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 overflow is 
integral part of the stand pipe.
STRAINER SYSTEM: Equipped with large, exclusive self-
flushing, 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 flame 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 liquefied 
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).
