TSC-66 Traditional
Series
Specifications
NOTE:
The TSC-66 series conveyor dishmachines are
N
SF International Inc. (NSF) and Underwriters
Laboratories Inc. (UL) listed. They also meet the require-
ments of A.S.S.E. Standard No. 1004.
PERFORMANCE:
Fully automatic, single tank, rack
conveyor dishwasher designed to wash, rinse, and sani
-
tize tableware and utensils commonly associated with
the preparation and consumption of food items in a com-
mercial foodser
vice operation. Sanitization is accom-
plished through hi-temp sanitization utilizing 180-195°F
fresh water rinse. The unit conveys standard 20” x 20”
dishracks first through a recirculatied (120 GPM) 110 -
140°F prewash and then through a recirculating deter-
gent laden wash section where 270 gallons per minute
(GPM) of 160°F wash water is pumped over the dishrack
to remove the food soil. The rack is then 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 66 gallons per
hour between 180-195°F at 15-25 PSI flow pressure for
maximum hourly rack capacity of 119 racks per hour.
CONSTRUCTION:
All stainless steel components
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 wash tank, and
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:
Internal prewash pump located
inside the prewash tub is totally stainless steel as is the
impeller. T
he prewash pump itself is tot
ally integral with
the motor. prewash water is recirculated from the pre
-
wash tank through the manifolds and prewash arm system
at the rate of 120 G

CONVEY
OR SYSTEM:
R
acks are conveyed
through the machine by a center-mounted, heavy-duty
stainless steel pawl bar with stainless steel cast, counter-
weighted, wide surface pawls. The pawl bar is designed
to not interfere with spray patterns in the 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. 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 7.0 feet per
minute for hi-temp machines.
CHAMBER:
The chamber has a standard clearance
of 18”.
CONTROLS:
Controls are located in a stainless steel
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 wash and rinse sections only when a rack is
being washed or rinsed 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 circuitr
y will be operated from a 1
1
0 volt control
circuit transformer. The unit is completely wired with
105°C, 600V thermoplastic insulated wire and routed
through U
L approved conduit.
FILL:
Initial fill of the prewash tank and wash tank is
automatic when the machine is initially energized. The
prewash tank fill line needs to be hooked up to a 110 -
140°F potable water line; the wash tank fill line needs to
be hooked up to a 180°F minimum potable water line
which normally would be supplied by an external booster
heater or our optional Hatco booster heater packages. Fill
is controlled by standard solenoid valves and vacuum
breaker assemblies. The incoming water solenoids are
activated by stainless steel float systems located in the
tanks for required maintenance of the water levels.
RECIRCULATING PREWASH:
The prewash
tank itself has a 17.25 gallon capacity and maintains the
water level with a separate fill connection from the rest
of the mac
hine. The automatic fill is controlled through
an internal float and an external solenoid valve. Washing
action is accomplished by recirculating water in the pre-
wash t
ank through upper and lower prewash arms. All
prewash arms are easily removable and along with
removable end caps, are easily cleanable without the use
of tools.
R
ECIRCULATING WASH:
T
he wash tank itself
has a 20.4 gallon capacity and maintains that level with
a skimming type overflow. Washing action is accom-
plished by recirculating detergent laden water in the
wash tank through upper and lower wash arms. Make-up
water comes from the final rinse section and is con-
trolled at approximately 2 GPM. The arms themselves are
extended and create a longer wash section than compet-
itive models. Wash section is automatically activated by
racks as they pass through. Wash arms, upper and lower,
contain 36 separate stripping nozzles for superior perfor-
mance. All 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 pro-
vided to allow easy installation of detergent concentra-
tion sensor and dispenser tubing by others.
FINAL RINSE:
Fresh pressurized rinse water enters
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 into the final
rinse line by others. Total final rinse flow rate is 3.9 GPM.
DRAIN, OVERFLOW, AND MAKE-UP:
The
machine is designed to maintain appropriate wash tank
water levels at all times even at low pressures. T
he over-
flow system is designed to automatically skim the sur-
face of the wash tank. 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. A large lever locat-
ed on the front panel of the machine operates a drain
valve and drains the machine completely.
PRESSURE REDUCING VALVE:
Factory
installed on incoming water line to control water pressure.
