Specifications
The AJ-66 series conveyor dishmachines are
NOTE:
listed by the National Sanitation Foundation (NSF),
Underwriters Laboratories Inc. (UL), and by the Canadian
Standards Association (CSA). They also meet the requirements of A.S.S.E. Standard No. 1004.
PERFORMANCE:
conveyor dishwasher with a recirculating prewash
designed to wash, rinse, and sanitize tableware and utensils commonly associated with the preparation and consumption of food items in a commercial foodservice operation. Sanitization is accomplished either through hi-temp
sanitization utilizing 180-195°F fresh water rinse or
through low-temp sanitization utilizing a sanitizer agent
(5.25% sodium hypochlorite) injected into 140°F minimum
fresh water rinse. The unit conveys standard 20” x 20”
dishracks through
120 gallons per minute (GPM) of 110-140°F water is
pumped over the rack to mechanically prepare the tableware for washing. Next, the rack is conveyor driven into a
detergent laden wash section where 270 GPM of 160°F
(140°F in a low-temp chemical sanitizing machine) wash
water is pumped over the dishrack to remove the food soil.
Finally, the rack is conveyor driven into a final rinse section where a fresh water final rinse spray system removes
residual detergent and sanitizes. For hi-temp sanitizing, the
unit must be installed to a potable water line capable of
supplying 234 gallons per hour between 180-195°F at 20
PSI flow pressure for maximum hourly rack capacity of
248 racks per hour. For low-temp sanitizing, the unit must
be installed to a potable water line capable of supplying
234 gallons per hour betwee
flow pressure for maximum hourly rack capacity of 234
racks per hour. An NSF recognized chemical feeder system must be supplied and installed by others and must
inject a minimum of 50 PPM 5.25% sodium hypochlorite
(chlorine) into the final rinse line to meet chemical sanitization requirements.
CAUTION:
have an adverse effect on materials including, but not limited to, silver and silver plate, pewter, and aluminum.
CONSTRUCTION:
304 series stainless steel. No 400 series stainless steel
and/or plastics are utilized. Frame is constructed of 2”
diameter stainless steel tubing formed and completely
saddle welded for superior strength. The prewash tank,
wash tank, and rinse chamber are formed and heliarc

WASH PUMP:
wash tub is totally stainless steel as is the impeller. The
wash pump itself is totally integral with the motor. Wash
water is recirculated from the wash tank through the
manifolds and wash arm system at the rate of 270 GPM.
PREWASH PUMP MOTOR:
enclosed, fan cooled type motor drives the prewash pump
and arms. Single-phase motors are capacitor start, induction run with internal thermal overload protection. Threephase motors are i

Single-phase motors are capacitor start, induction run with
internal thermal overload protection. Three-phase motors
are induction run with external overload protection. Motor
shaft is supported by permanently lubricated grease
packed ball bearings.
CONVEYOR SYSTEM:
through the machine by a center-mounted, heavy-duty
stainless steel pawl bar with stainless steel cast, counterweighted, wide surface pawls. The pawl bar is designed to
not interfere with spray patterns in the prewash, wash,
and rinse section. The pawl bar is driven by a 1/4 HP
motor and worm drive gear reduction unit. The conveyor
motor itself is totally enclosed, non-ventilated. Singlephase motors are capacitor start, induction run with internal thermal overload protection. Three-phase motors are
induction r
conveyor drive unit is mounted on the left hand side of the
machine and is enclosed with a removable stainless steel
cover. Maximum conveyor speed is 6.9 feet per minute for
hi-temp machines and 6.5 feet per minute for low-temp
chemical sanitizing machines.
ADJUST-A-PEAK:
mechanical feature located on the pawl bar drive unit itself
and allows the end-user to slow down the speed of the
conveyor drive unit when enhanced results are required
(i.e. baked-on food soil) or increase the speed of the conveyor drive unit when maximum capacity is required. By
slowing down the conveyor, a rack of tableware remains in
the prewash, wash, and rinse sections for longer periods of
time. When soil loads are heavy (i.e. pots and pans, trays,
and bun pans), adjusting the conveyor to slower speeds
means outstanding results.
CHAMBER:
25” which is the highest clearance in the industry---even
higher than competitive higher hood options. This adds to
the versatility of the machine since you can easily accommodate larger utensils such as sheet pans an
mixing bowls. The combination of a higher hood in conjunction with manually slowing down the conveyor utilizing
the Adjust-A-Peak feature produces superior results as
well as adding to the versatility of the machine.

CONTROLS:
control box mounted on top of the machine for ease of
access and increased reliability. Power “ON/OFF” switch
is the only manual switch required. “Energy Guard” fully
automates the machine and utilizes switching logic to
operate prewash, wash, and rinse sections only when a
rack is in place as well as turning the conveyor off when a
rack exits the machine and there are no other racks in the
machine. Regardless of machine voltage, all control circuitry will be operated from a 110 volt control circuit transformer. Again, the Adjust-A-Peak feature eliminates the
need for manual controls since you have the ability to slow
down the conveyor for extended prewash, wash, and rinse
contact time. The unit is completely wired with 105°C,
600V thermoplastic insulated wire and routed through UL
approved conduit.
a manual reset 1 AMP overload protector located on the
front of the control box.
FILL:
automatic when machine is initially energized. There are
separate fills to each tank and each is controlled by its
own standard solenoid valve and vacuum breaker assembly. The prewash tank needs to be hooked up to a water
line capable of filling with 110-140°F incoming potable
water rather than filling with 180°F from the booster
heater through the wash tank as does the competition. If
the cold water thermostat option is utilized in the prewash,
an additional cold water line needs to be hooked up to the
machine. The wash tank fill line needs to be hooked up to
a 180°F minimum incoming potable water line which normally would be supplied by an external booster heater or
our own optional Hatco booster heater packages. The fill
solenoids for both tanks are activated by stainless steel
float systems located in the individual tanks for required
maintenance of tank water levels.
RECIRCULATING PREWASH:
itself has a
with a skimming type overflow. Prewashing action is
accomplished by recirculating 110-140°F water through 12
separate stripping nozzles through two upper arms and
one lower arm. This superior action removes heavy soil
and deposits it in a large outside deep well scrap basket
located on the front of the machine for easy access. A
secondary removable pump intake strainer protects the
pump itself. Make-up water comes from the wash at the
rate of approximately 2 GPM. All three wash arms are easily removable and along with removable prewash arm end
caps, are easily cleanable without the use of tools.
RECIRCULATING WASH:
15.4 gallon capacity and maintains that level with a skimming type overflow that flows excess wash water into the
prewash tank. Washing action is accomplished by recirculating detergent laden wash water in the wash tank
through upper and lower wash arms. Make-up water
comes from the final rinse section and is controlled at
approximately 2 GPM. The arms themselves are extended
and create a longer wash section than competitive models.
Controls are located in a stainless steel

Wash section is automatically activated by racks as they
pass through. Wash arms, upper and lower, contain 43
separate stripping nozzles for superior performance. Both
wash arms are easily removable and along with removable
wash arm end caps, are easily cleanable without the use
of tools. Large stainless steel strainer pans as well as a
pump intake strainer for secondary protection are readily
accessible and removable for cleaning purposes.
Knockouts and connections are provided to allow easy
installation of detergent concentration sensor and dispenser tubing by others.
FINAL RINSE:
the machine through a standard “Y” strainer, solenoid
valve, and approved vacuum breaker assembly and is
plumbed to upper and lower final rinse arms located at
the output end of the machine. Single rows of fan jet
nozzles are located on both rinse arms. Connection points
are provided for both rinse agent injection and sodium
hypochlorite (low-temp chemical sanitizing machines
only) into the final rinse line by others. Total final rinse
flow rate is 3.9 GPM.
DRAIN, OVERFLOW, AND MAKE-UP:
machine is designed to maintain appropriate prewash and
wash tank water levels at all times even at low pressures.
The overflow system is designed to automatically skim the
surface of both tanks. Make-up water from the final rinse
system not only replenishes the wash water but also helps
maintain appropriate water levels as well as appropriate
wash tank temperatures. Large levers located on the front
panel of the machine operate drain valves and drains the
prewash and wash tanks completely.
