Installation, Operation, and Care Of
C-LINE A, W, & AW DISHWASHERS
SAVE THESE INSTRUCTIONS FOR FUTURE USE
GENERAL
C-Line A, W, or AW Dishwashers are fully automatic, rack-type washers that convey the rack from
one end of the machine to the other, exposing the ware to progressive wash / rinse action. It has a
stainless steel tank and chamber with a welded stainless steel angle frame, stainless steel legs, and
stainless steel adjustable feet. Front inspection door(s) provide access to the interior of the wash
chambers. CRS and CPW models also have a prewash inspection door. The C44A/AW, CRS66A/AW,
CCS66A/AW, CPW80A/AW, C64A, CRS86A, CCS86A, and CPW100A machines are the only models
capable of either high- or low-temperature operation. The C88A and C88W families are not available
for low-temperature operation. Machines are available with steam, gas, or electric heat. A Prewash
Unit or Recirculating Scrapper are also available.
Model C44A
Right to Left Operation
– 4 –
STANDARD EQUIPMENT
Controls (Fig. 1)
Fig. 1
The controls are mounted on top of the chamber. There are three operational control switches housed in
the control box: Power (On-Off); Motor (On-Off); and Timer (Manual-Auto). A pilot circuit transformer
provides a reduced voltage of 115 volts for the machine controls. When equipped for gas heat, a step-down
transformer provides a reduced voltage of 24 volts for the igniter board(s) and valves.
Motor and Pump Units
The wash / rinse pump and motor are centrifugal-type cast stainless steel with stainless steel impeller. The
2 HP motor is available in the following voltages:
Volts Hz Phase Volts Hz Phase
208-240 60 1 200-240 50 3
208-240 60 3 380-415 50 3
200-240 50 1 380 60 3
480 60 3
600 60 3
1
The conveyor drive motor is a
⁄6 HP gear motor with the same voltage as the wash / rinse pump motor.
A 1 HP prewash pump motor is standard on CRS, CCS, and CPW models. A 2 HP prewash pump motor
is optionally available on the CPW models only. Voltage and construction are the same as the wash / rinse
pump motor.
All motors have built-in thermal overload protection with manual reset.
Vacuum Breakers
The final rinse and fill lines contain atmospheric vacuum breakers that prevent any reverse flow of water
from the dishwasher into the potable water supply.
Heater Protection
A float-activated switch located in the wash tank (and rinse tank if included) automatically turns off the heat
supply if the water level is too low. Once the water returns to the proper level, the heating circuit becomes
operational if heat is demanded.
An overtemperature protector is also provided for electric and gas heat. If overheating should occur, the
heat supply will be turned off. Turn the Power switch Off and contact your local Hobart service office.
– 5 –
Thermometers
Dial thermometers for wash and final rinse are indicated in
°
F and °C on the faceplate.
Door Interlocks
Door interlock switches will prevent machine operation while an inspection door is open. If a door is opened
while the machine is operating, the pumps and conveyor will automatically turn off. After the door is closed,
the machine must be restarted by pushing the Motor switch On.
Wash and Rinse Arms
Upper and lower prewash, wash, and final rinse arms are removable. All machines have metal final rinse
arms. A CPVC final rinse piping system is available for those machines offering low temperature operation
(if so ordered).
RS Unit and CS Unit
CCS86A, CCS110A, CCS86W, CCS110W)
(CRS66A, CRS66AW, CRS76A, CRS86A, CRS110A , CRS86W, CRS110W, CCS66A, CCS66AW, CCS76A,
The 22" Recirculating Scrapper is a power prewash unit which uses overflow water, hence, no fill valve is
required.
PW Unit
(CPW80A, CPW80AW, CPW90A, CPW100A, CPW124A, CPW100W, CPW124W)
The 36" Prewash unit is a large power prewash unit which uses overflow water, hence, no fill valve is
required.
Dual Rinse Unit
(C64W, CRS86W, CCS86W, CPW100W, C88W, CRS110W, CCS110W, CPW124W)
The 36" Dual Rinse Unit provides a dedicated final rinse in combination with a pumped auxiliary rinse. The
dual rinse section is only available on two-tank C64A or C88A parent units.
Auto Fill
Close door(s) and push the Power switch On. After a 5-second delay, the machine fills automatically.
Auto Timer
The Auto Timer switch is located on the left side of the control box. Designed to save electrical power, it
is adjusted to shut off pump and drive motors a set amount of time after the last rack exits the dishwasher.
To restart, slide a rack into the machine or push the Motor switch On. To change the time setting, contact
your local Hobart-authorized service office.
Common Drain
A stainless steel common drain tube connects the dishwasher and prewash drains together, thus requiring
only one drain connection at installation. A unit with a dual rinse section is also plumbed for a common drain.
Front Panel
Stainless steel front panel conceals pumps and plumbing.
Common Water Connection
A single water connection for Fill and Final Rinse is standard. This requires a minimum incoming water
temperature of 180°F for high-temperature machines (140°F for low-temperature machines).

INSTALLATION
UNPACKING
Immediately after unpacking the dishwasher, check it for possible shipping damage. If this machine is
found to be damaged, save the packaging material and contact the carrier within 15 days of delivery.
Prior to installation, verify that the electrical service agrees with the specifications on the machine data
plate, which is located on the right-hand side of the control box.
The electrical diagram is located on the inner surface of the control box cover.
After unpacking the dishwasher, remove the items shipped uninstalled (overflow tube, pump intake
strainer, curtains, and chamber hole plug kit) and instructions from inside the dishwasher. Set the
dishwasher in its proper location. Adjust the height and level by turning the adjustable feet. NOTE: The
dishwasher must be positioned and leveled before making plumbing connections. Remove shipping block
from the drive motor.
INSTALLATION CODES
Installation must be in accordance with state and local codes, or in the absence of local codes, with
the National Fuel Gas Code, ANSI Z223.1 (latest edition) if applicable, and the National Electrical Code
ANSI/NFPA 70 (latest edition). In Canada, the installation standards are: CAN/CGA B149.1,
CAN/CGA B149.2, and CSA C22.2 No.1 (latest editions).
ASSEMBLY
Dish tables should be fitted into the dishwasher (Fig. 2). Use Mastic between table and lip of tank to prevent
1
leakage. Rack track height should be from
⁄4" to 5⁄16" (Fig. 2) above the tank lip. Dish tables should be sloped
so that any water carried from the dishwasher will drain back into it.
Fig. 2
– 8 –
Remove the strainer basket and strainer pans from the wash chamber (Fig. 3).
Place the pump intake strainer on the three hooks as shown in Fig. 4.
Place the overflow tube in the retainer (Fig. 5).

Shipping length limitations require that the Dual Rinse Unit be shipped separately on longer three-tank
machines. Assemble as follows:
Remove Front Panels and Wireway Covers from both parent machine and Dual Rinse unit.
Remove Track bolts and nuts at the connecting end of both Parent machine and Dual Rinse unit. Save
the longer bolts (and washers and nuts) for reconnection of tracks after Parent machine and Dual
Rinse units are bolted together.
