FOOD EQUIPMENT
Printed On Recycled Paper
DESIGN: Fully automatic, flight-type dishwasher
machine, consisting of a 5' x 7' loading section
with power recirculating prewash, an 8' power
wash, power rinse and fresh water final rinse
section, and a 5', 7', 9' or 11' drying and
unloading section. Recirculating water prewash,
power wash, power rinse, and final rinse
compartments constructed with splash baffles
and flexible plastic strip curtains for effective
control and separation of spray systems. Specify
high or low temperature operation.
CONSTRUCTION: Tank and chambers are
heavy gauge stainless steel with No. 3 polish
on appearance surfaces. Stainless steel
frames, legs, and feet are standard. Three large
inspection doors with welded handles.
PUMPS: Recirculating pumps with Ni-Resist
impellers and face seal with stainless steel
metal parts and ceramic seat. Readily
removable motor-impeller assembly permits
quick inspection. All pumps are self-draining.
MOTORS: Hobart-built, grease-packed ball
bearings, splashproof design, ventilated with
inherent overload protection in each motor.
Recirculating prewash unit 2 H.P., power wash
and power rinse 3 H.P. each, conveyor

2 H.P.
Available in electrical specifications of
200-230/60/3 and 460/60/3 with manual reset.
CONTROLS: A stainless steel control center
with Power “On/Off” switch is mounted on top of
the center section. Controls use 115 volt pilot
circuit. Recessed “Start/Stop” controls at each
end of machine in stainless steel enclosure,
factory wired. Electrical components are
completely wired with 105°C, 600V thermo-
plastic insulated wire with stranded conductors
routed through covered wireway built into the
front of the machine above tank water level and
UL Listed electrical metallic tubing or liquid-tight
flexible metal conduit. Locking style electrical
connectors are used for connections between
machine sections. As an energy saving control
feature, operation of pumps, final rinse and
optional blower-dryer stop when conveyor stops.
FLIGHT TYPE CONVEYOR: Stainless steel
side links, and tie rods and conveyor tracks.
Injection molded, resilient Duraflex flight links to
accommodate flatware and trays in preferred
inclined position.
VAPOR CONTROL: Built in vent ducts with
dampers and drip shields located on both
ends of machine. Load end duct connection is
2" x 24" inside. Unload end duct connection is
4" x 24" inside.
RECIRCULATING PREWASH SECTION:
Removes soil by means of recirculated water
sprayed over dishes before they enter the power
wash zone. The unit receives its water from two
sources. The design provides for receiving all
detergent overflow water from the wash tank
and all the rinse tank overflow. Prewash
compartment is fitted with stainless steel upper
and lower wash arms having specially shaped
nozzles with large openings arranged to
effectively remove soil from all types of ware.
Prewash flushdown is supplied as standard.
Large removable one-piece perforated
stainless steel screen sloped downward to
deep perforated stainless steel basket. Baskets
and screens are removable from front of
machine.
DRAIN AND OVERFLOW: Prewash tank
equipped with bell type overflow and drain
valve. Closing the inspection door will
automatically close the drain valve.
POWER WASH AND POWER RINSE: Power
wash and power rinse tanks are equipped with
upper and lower stainless steel wash arms
with specially-shaped nozzles having large
openings and arranged to effectively direct
water jets to all ware surfaces. Wash arms are
easily removable without use of tools. Large
one-piece removable perforated stainless steel
screen sloped downward to deep perforated
stainless steel baskets. Baskets and screens
removable from front of machine.
DRAIN AND OVERFLOW: Power wash and
power rinse overflow system directs water
through internal connecting stainless steel
tubing to prewash section. Drain valve is
controlled from front of machine and is
automatically closed by closing inspection door.
TANK HEATING: Power Wash tank and Power
Rinse tank water temperatures are each
thermostatically controlled. The tank heat with
positive low water protection is automatically
activated when the Power switch is turned “On.”
If the tank is accidentally drained, the low water
protection device automatically turns the tank
heat off. Select one of the optional heats listed
under Optional Equipment—Tank Heating.
FINAL RINSE: Upper rinse arm has two rows of
nozzles above and lower arm has one row of
nozzles below dishware. Final rinse water line is
equipped with vacuum breaker on downstream
side of solenoid valve. Design provides for
collection and division of final rinse water after
use to power wash tank and power rinse tank.
Sanitizer and rinse agent dispenser injection
ports provided in final rinse piping above rinse
chamber. Final rinse water saver “Rinse Gate”
supplied as standard energy saving feature.
Machine (line) voltage, fuse protected terminal
provision for detergent and rinse agent
dispensers.
CONVEYOR DRIVE UNIT: Powered by a
Hobart-built, inherent overload protected
1
2 H.P. grease packed ball bearing motor. Trip
mechanism provided on unloading end of
conveyor. Jam protection is provided by load
sensing switch at drive platform. These devices
interrupt operation of the conveyor motor which
stops the conveyor, pumps and final rinse
flow. Operation is restarted automatically by
removing item which has actuated the trip
mechanism, or by operator switch if shutdown
resulted from other cause.
