STANDARD FEATURES Continued
The system is complete with the standard and optional
equipment listed in this specifi cation. All sections are
effectively baffl ed, and water from the fi nal rinse is completely
controlled for repeated use until it is fi nally disposed of
through the waste disposal system.
Construction: Fully welded 16 gauge, type 304/18 – 8, No. 4
mill fi nish stainless steel tanks, hood, frame, legs and adjustable
feet. The entire tank area is covered with stainless steel
perforated strainer pans which are easily removable by hand for
cleaning. All internal construction is stainless steel. The machine
is NSF standard No. 3 approved and conforms to UL 921.
Conveyor Table: The conveyor table is constructed from 12
gauge, type 304/18 – 8, No. 4 mill fi nish stainless steel. The
table is 24" front to back and has the front edge turned up 3"
and the back edge turned up 13". The conveyor table and turned
up edges are in one piece with radius corners and all the edges
hemmed to form a smooth watertight continuous table.
The table has watertight butt joints, located where necessary to
allow for the easy movement and assembly of the system. The
system does not require any fi eld welding to install. The table is
supported by stainless steel leg sets with one leg forward and one
leg back, and with a cross brace for strength and rigidity. Each leg
has adjustable stainless steel bullet feet. The sets are mounted
to the table on approximately 3 foot centers. The table has formed
stainless steel conveyor tracks mounted to the front and back of the
turned up edges and at a height to keep the conveyor from touching
the table. The table is pitched from the clean portion to the soiled
area for water drainage.
Conveyor: The conveyor consists of a series of stainless steel 20"
square dollies each of which has four single rack stainless steel ball
bearing wheels. These wheels roll in the aforementioned tracks and
hold the dollies up off of the table. The dollies are interconnected,
and when moving from a continuous conveyor, traveling in the
direction shown on the plan. Each dolly is equipped with a plastic
all-purpose rack which receives most types of soiled ware and holds
it in the position for washing. Every third dolly is equipped with a
wiper which conveys water and food soil that drops onto the table, to
the scrapping tank for removal. The conveyor system is powered by
a ½ HP variable speed drive. The drive assembly rotates a stainless
steel chain which, in turn, engages three dollies simultaneously,
providing the propelling force. Because the conveyor system rolls
on ball bearing wheels, it can be moved forward manually in case
a jam occurs. The entire drive assembly is mounted in the table
backsplash, outside of the machine proper and away from any
possible contamination by food soil. The conveyor has start-stop
switch located at stations convenient to the operators. The conveyor
can be stopped or started without turning off the machine itself.
Power Scrapper: The power scrapping section is mounted in the
curved 90° quadrant as indicated on the plan. Stainless steel center
fed manifolds above and below the ware with stricture free jets and
directional vanes are interchangeable, upper and lower and from
tank to tank and easily removed without tools. A 2 HP, 1750 rpm
pump and motor is capable of spraying 225 GPM of pre-wash water
over the ware. Manifold water restrictors are provided so that water
pressure from top to bottom can be adjusted to the type of ware
being washed. The motor has an easily removable front inspection
plate and is self-draining. The food soil drops onto stainless steel
strainer pans which cover the tank. The screens are held in an
inclined position, which, coupled with the water action, fi nal rinse
feedback and scrapping trough, automatically moves the food soil to
the waste system mounted outside the tank. A 12" wide, 12 gauge
stainless steel scrap trough, mounted outboard of the conveyor
table, is part of the scrapping system. It is in the shape and length
as shown on the plan. The trough has a water inlet at the head
which is controlled manually by the operator. The heavy food soil is
deposited in the trough and is fl ushed directly to the waste disposal
system. The food soil deposited in the trough, and the soil which is
removed by the scrapping action, are both transferred to the waste
disposal system continuously and automatically. The scrapper is
also equipped with a cold water aquastat that control the water
temperature in the scrapper tank so that food proteins are not baked
onto the ware due to excessive heat.
Mandatory Power Wash: Stainless steel center fed manifolds
above and below the ware with stricture free jets and directional
vanes are interchangeable, upper and lower and from tank to
tank and easily removed without tools. Stainless steel end caps
are removable without tools. A 2 HP, 1750 rpm pump and motor
is capable of spraying 225 GPM over the ware. Manifold water
restrictors are provided so that water pressure from top to bottom
can be adjusted to the type of ware being washed. The motor has
an extended stainless steel shaft with packless ceramic seal. The
pump has easily removable inspection plates, front and end, and is
self-draining.
Power Rinse: Stainless steel center fed manifolds above and
below the ware with stricture free jets and directional vanes are
interchangeable, upper and lower and from tank to tank and easily
removed without tools. Stainless steel end caps are removable
without tools. A 2 HP, 1750 rpm pump and motor are capable of
spraying 225 GPM over the ware. Manifold water restrictors are
provided so that water pressure from top to bottom can be adjusted
to the type of ware being washed. The motor has an extended
stainless steel shaft with packless ceramic seal. The pump has
easily removable inspection plates, front and end,
and is self-draining.
Final Rinse: Stainless steel fi nal rinse arms are mounted above
and below the ware. The fi nal rinse is activated only when ware is

in the fi nal rinse section by a rinse rake. Continuous rinsing, or
rinsing action in conjunction with conveyor operation will not be
acceptable. The expended fi nal rinse water is piped directly to
the power scrapper tank for reuse, by-passing the power wash
tank completely. This ensures that the wash detergent is not
diluted. The fi nal rinse is isolated from the preceding stage which
prevents splash over and assures a proper rinse. The fi nal rinse
is contained in a 24" long 16 gauge stainless steel hood.
Clean-up Hose: The warewashing system is provided with a
quick-coupling hose bib, plumbed in the 140° water supply
line complete with a 25
hose and nozzle to facilitate cleaning
procedures on the warewasher and general clean-up in the

and machine has the approval of the Underwriters Laboratory,
as well as the California Industrial Accident Commission Safety
Regulation, electrical division. All internal wiring of the machine is
complete in waterproof conduit and fi ttings and terminates in the
enclosure to a make-up box.
Mounted Circuit Breakers: The warewashing system is equipped
with mounted circuit breakers housed in a stainless steel panel
in conjunction with the main control panel. Each motor, including
the disposer, are protected by an individual circuit breaker.
One three-wire service is suffi cient for connecting the electrical
service. This ensures that the warewashing system is wired
correctly and that any electrical motor or element failure does not
shut the machine down.
