PERFORMANCE:
rack conveyor dishwasher with a recirculating prewash
designed to prewash, 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 through hitemp sanitization utilizing 180-195°F fresh water rinse.
The unit conveys standard 20” x 20” dishracks through a
recirculating prewash section where 120 gallons per
minute (GPM) of 110-140°F water is pumped over the
rack to mechanically prepare the ware for washing. Next,
the rack is conveyor driven into a detergent laden wash
section where 270 gallons per minute of 150°F wash
water is pumped over the dishrack to remove the food
soil. It then enters the power rinse section where a recirculating rinse of 160°F water at 270 GPM is pumped
over the dishrack. Finally, the rack is conveyor driven into
a final rinse section where a fresh water final rinse spray
system removes remaining residual detergent and sanitizes. The unit must be connected to a potable water line
capable of supplying 222 gallons per hour between 180195°F at 15-25 PSI flow pressure for maximum hourly
rack capacity of 287 racks per hour.
CONSTRUCTION:
are 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, recirculating rinse tank, and final rinse chamber are formed and heliarc welded 16 gauge #2B finish.
Hood is 16 gauge #3 finish. Stainless steel feet are
adjustable ±1/2”.
PREWASH PUMP:
inside the prewash tub is totally stainless steel as is the
impeller. The pump is integral with the motor and selfdraining. Prewash water is recirculated from the prewash
tank through the manifolds and prewash arm system at
the rate of 120 GPM.
PREWASH PUMP MOTOR:
enclosed, fan cooled type motor drives the prewash
pump. 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.
WASH PUMP:
wash tub is totally stainless steel as is the impeller. The
pump is integral with the motor and self-draining. Wash
water is recirculated from the wash tank through the
manifolds and wash arm system at the rate of 270 GPM.

with the motor and self-draining. Wash water is recirculated from the power rinse tank through the manifolds
and wash arm system at the rate of 270 GPM.
POWER RINSE PUMP MOTOR:
ly enclosed, fan cooled type motor drives the wash
pump. Single-phase motors are capacitor start, induction
run with internal thermal overload protection. Threephase 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
not to interfere with spray patterns in the prewash, wash,
recirculating rinse, and final 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. Single-phase motors are capacitor start,
induction run with internal thermal overload protection.
Three-phase motors are induction run with external overload protection. Pawl bar 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 8.0 feet per minute.
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:
of 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 and 60
quart 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, recirculating rinse and final 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, recirculating rinse
and final rinse contact time. The unit is completely wired
with 1
05°C, 600V thermoplastic insulated wire and routed through UL approved conduit. The control circuit is
protected by a manual reset 1 AMP overload protector
located on the front of the control box.
FILL:
Initial fill of the prewash, wash and power rinse
tanks are automatic when machine is initially energized.
There is a fill line to the wash and power rinse tanks and
a separate fill line to the prewash tank. Each fill line is
controlled by its own 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. 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 and
power rinse 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
tank water levels.
RECIRCULATING PREWASH:
tank has a 16.0 gallon capacity and maintains that level
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. Make-up water comes from the wash tank at the
rate of approximately 2 GPM. All three prewash arms are
easily removable and along with removable end caps, are
easily cleanable with
RECIRCULATING WASH:
15.4 gallon capacity and maintains that level with a skimming type overflow. Washing action is accomplished by
recirculating detergent laden water in the wash tank
through upper and lower wash arms. Make-up water
comes from the power rinse section and is controlled at
approximately 2 GPM. The wash arms are 18” long. 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.

type overflow. Rinsing action is accomplished by recirculating final rinse water in the 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 are 12” long. The power rinse section is automatically activated by racks as they pass through. Power
rinse arms, upper and lower, contain 32 separate stripping nozzles for superior performance. Both power rinse
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.
FINAL RINSE:

valve, and approved vacuum breaker assembly which is
plumbed to upper and lower final rinse arms located at
the output end of the machine. A single row of fan jet
nozzles are located on both rinse arms. Connection point
is provided for rinse agent injection into the final rinse
line by others. Total final rinse flow rate is 3.7 GPM.
DRAIN, OVERFLOW, AND MAKE-UP:
machine is designed to maintain appropriate prewash,
wash, and power rinse tank water levels at all times even
at low pressures. The overflow system is designed to automatically skim the surface of the prewash, wash, and
power rinse tanks. Make-up water from the final rinse
replenishes the power rinse tank which replenishes the
wash tank, which in turn replenishes the prewash tank as
well as maintains appropriate water levels and temperatures. Large levers located on the front panel of the
machine operate valves that drain the machine completely.
