MICROCOMPUTER CONTROLS FOR RELIABILITY AND PERFORMANCE

The new microcomputer control provides LED digital display of cycle (Fill, Wash, Rinse) and temperature. Built-in, self
diagnostics makes service fast and easy, if it should ever be needed.

The AM-14 is field convertible to either hot water or low temperature chemical sanitizing and features “flexible timing for
special applications”. Capacity varies from 52 racks per hour to 80 racks per hour depending on operating mode.
Unit has equal capacity to some two-rack fill and dump dishwashers, but requires only half the space and consumes
less water.

AM-14/AM-14C
DISHWASHERS

The microcomputer-based control system is built into the AM-14
Series Dishwashers. Model AM-14 is for straight-thru operation with
a third (front) door for inspection, and AM-14C for corner installation.
Each is available in standard electrical specifications of 208-240/60/1,
208-240/60/3, 480/60/3 and all are 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 2-6 GR. FOR BEST
RESULTS.

CONSTRUCTION: Tank and wash chamber constructed of

#16 gauge stainless steel, arc-welded. Unitized welded stainless
steel tank, frame and stainless steel feet. Wash chamber and front
of tank above motor compartment are polished satin finish. Stainless
steel snap-in front panel – no fasteners required.

DOOR LIFT: Doors coupled by stainless steel door handle, spring
counterbalanced (except the front inspection door). All doors guided
for ease of operation and long life.

PUMP: With Ni-Resist 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, 1 H.P., with inherent thermal protection,
grease-packed ball bearings, splashproof design, ventilated.
Single-phase is capacitor-start, induction-run type. Three-phase is
squirrel-cage, induction type.

MICROCOMPUTER CONTROL SYSTEM: Hobart microcomputer
controls, assembled within water-protected enclosure, provide built-in
performance and reliability.

The microcomputer control, switches and contactors are housed in a
single stainless steel enclosure, mounted on right-hand or left-hand
side (AM14) or 90° (AM14C) of dishwasher below table level. Control
enclosure is field adjustable to an alternate lower position of 1011⁄16"
from table. The line voltage electrical components are completely
wired with 105°C, 600V thermoplastic insulated wire with stranded
conductors and routed through listed electrical conduit. Low-voltage
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 LED remains on during this period, completing the
program. If the microcomputer is interrupted during a cycle by the
door-cycle switch, the microcomputer is reset to the beginning of the
program. Hot Water Sanitizing – 62 seconds (AM14: 53 Racks/hr.;
AM14C: 52 Racks/hr.): 40 Second Wash, 4 Second Dwell, 9 Second
Rinse, 9 Second Sani-Dwell. Chemical Sanitizing (Normal Duty) –

53 Seconds (AM14: 62 Racks/hr.; AM14C: 60 Racks/hr.):
40 Second Wash, 4 Second Dwell, 9 Second Rinse. Chemical
Sanitizing (Light Duty) – 40 Seconds (AM14: 80 Racks/hr.;
AM14C: 76 Racks/hr.): 27 Second Wash, 4 Second Dwell, 9 Second

Rinse (130°F Minimum). All of the above programs and many more
can be pre-selected by your Hobart service technician.

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: Upper revolving rinse arm with eight rinse spray nozzles.
The stainless steel upper and lower rinse arms are easily removable
without tools. Lower revolving rinse arm with eight nozzles lifts out for
inspection. 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 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 doors. Drain seal is large diameter, high
temperature “O” ring. Cover for overflow is integral part of stainless
steel strainer system.

STRAINER SYSTEM: Equipped with large, exclusive self-flushing,
easily removable perforated stainless steel strainer and large
capacity soil basket. Submerged soil basket minimizes frequent
removal and cleaning.

HEATING EQUIPMENT: Standard tank heat is 5KW electric
immersion heating element. Regulated power immersion tube gas
burner system is optional at extra cost. A solid-state ignitor board
controls the gas valve and provides flame ignition. A transformer
steps the control circuit voltage down to 24 volts to power the ignitor
board and gas valves. Gas Heated Dishwasher: For natural gas, gas
pressure (customer connection) not to exceed 7" W.C. For liquified
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.

STANDARD EQUIPMENT: In addition to the standard features listed
on the front are the following–latest design door cycle switch, ratio fill,
stainless steel adjustable feet. Adjustable height control panel.
Chamber, tank and all doors of 16 gauge stainless steel. Detergent
injector and sensing connections provided as well as connection in fill
line for rinse agent and sanitizer dispensing. Manual by-pass switch.

OPTIONAL EQUIPMENT AT EXTRA COST – ELECTRIC
BOOSTER HEATER: Electric booster adequately sized to raise

110°F inlet water to 180°F (not available on gas heat machines).
Pressure gauge for incoming water.

CONTROLS: Optional 90° controls on C models.
ACCESSORIES: 193⁄4" x 193⁄4" Peg and Combination All-Plastic

Dishracks. Desirable functional accessories can be furnished at
added cost. See listed options and accessories on this specification
sheet. Write to the factory for special requirements not listed above.
