Installation, Operation and Care Of
CL-SERIES DISHWASHERS
SAVE THESE INSTRUCTIONS
GENERAL
CL machines are rack-type warewashers that move the racks from one end of the machine to the
other, exposing the ware to progressive wash and rinse zones. Pumps and final rinse are activated
by the inserted rack to energize the specific wash or rinse action needed. The CL-series machines
are offered in optional lengths, sections, features, and provide different speeds to meet productivity
and performance requirements. All CL-Series Dishwashers have electronic controls with digital
temperature displays.
The CL-DWR models have a drain water energy recovery system which includes drain water tempering
and all of the standard features of the CL. They use a heat exchanger to capture the energy from the
drain water and preheat incoming cold water for the final rinse. The CL-DWR units are only available
in hot water sanitizing mode, three phase, and come standard with a built-in electric booster heater,
which is designed to maintain final rinse temperature of 180°F with a minimum incoming cold water
temperature of 55 °F.
The CL-ADV models have an Automatic Soil Removal (ASR) system and include all of the standard
features of the CL-DWR. The ASR system automatically redirects food soil left over after pre-scrapping
to an external scrap basket located at the load end of the machine. This helps to keep the wash water
cleaner, reducing the frequency of water changes. This saves the customer money on chemicals
and water/energy. The CL-ADV-Series machines are only available in hot water sanitizing mode,
electric heat, three phase voltage supply, and come standard with a built-in electric booster heater.
The CL-ADV models are not available with a corner scrapper unit.
The CL-VL models have a ventless system and include all the standard features of the CL Base
models. The ventless system uses energy efficient heat-pump technology combined with energy
recovery to remove the need for direct venting while providing auxiliary heat to the wash tank. The
CL-VL machines require only a single cold-water supply and are only available in hot water sanitizing
mode, electric heat, three phase voltage supply, and come standard with a built-in electric booster
heater.
Tanks, chambers, frames, legs and adjustable feet are made of welded stainless steel construction.
Hinged inspection doors provide access to the interior wash and rinse zones. The CL66, CL76, and
CL86 models provide a 22-inch power scrapper section and hinged access door. The power scrapper
removes the heavy soil before the rack enters the wash zone.
Machines can be ordered as left-to-right or right-to-left operation and standard height or higher
than standard. Either electric, gas, or steam tank heat is specified at time of order. Machines come
standard ready to operate with high-temperature sanitizing mode.
Hobart offers three right-angle possibilities to put your machine in a corner installation (not available
on CL-VL models):
• The Side Loader moves the rack at a right angle into the machine from the scrapping area.
• The Direct Drive Unloader moves the rack at a right angle coming out of the machine to tabling
where the clean ware can be unracked.
• The Corner Scrapper puts a Power Scrapper in the corner location at the load end of your machine,
combining right angle entry with a scrapper section.

CHEMICAL SANITIZING
CL machines can be converted to operate with chemical sanitizing mode (with the use
of chemical sanitizers). Refer to Manager Menu programming instructions on page 30.
NOTE: Chemical sanitization is not available on the CL-DWR, CL-ADV, or CL-VL models.
CL models that operate with chemical sanitization use incoming water and final rinse water
at 120°F minimum.
INSTALLATION
UNPACKING
Immediately after unpacking the dishwasher, check for possible shipping damage. If the
machine is found to be damaged, save the packaging material and contact the carrier within
5 days of delivery.
NOTE: For CL-VL models, ventless heat pump assembly ships separate on its own skid.
Prior to installation, verify that the electrical service agrees with the specifications on the
machine data plate, which is located on the left-hand side of the control box.
After unpacking the dishwasher, remove the items shipped loose (standpipe, splash shields,
curtains, literature envelope with instructions and chamber hole plug kit) from inside the
dishwasher. For CL-ADV models only, remove the external ASR basket from inside the
dishwasher and install in the ASR housing located at the load end of the machine.
VENTLESS HEAT PUMP ASSEMBLY INSTALLATION
Refer to Hobart Service CL Ventless Installation manual, F-41299 .
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/CSA B149.1 and CSA C22.1 (latest editions).
ADJUST MACHINE HEIGHT AND LEVEL MACHINE
Set the dishwasher in its proper location. Adjust the height and level the machine by turning
the adjustable feet in or out as necessary.
DISH TABLE ASSEMBLY
Dish tables should be fitted into the dishwasher (Figs. 1, 2 & 3). Use silicone sealant between
table and lip of tank to prevent leakage. Dish tables should be sloped so that any water
carried from the dishwasher will drain back into the machine, but not from the scrapping area.
NOTE: The dishwasher must be in its final position, adjusted for proper height and properly
leveled before table assembly and plumbing connections are made.

PLUMBING CONNECTIONS
Plumbing connections must comply with applicable sanitary, safety
and plumbing codes.
Water Requirements
Proper water quality can improve ware washing performance by reducing spotting, enhancing
effectiveness of labor and extending equipment life. Water conditions vary from one location
to another. The recommended proper water treatment for effective and efficient use of this
equipment will also vary depending on the local water conditions. Ask your municipal water
supplier for details about local water conditions prior to installation.
Recommended water hardness is 3 grains of hardness per gallon or less. Higher hardness
may cause excessive formation of lime scale. Water hardness above 3 grains per gallon
requires water treatment. Water treatment has been shown to reduce costs associated with
machine cleaning, reduce deliming of the dishwasher and reduce detergent usage in the
dishwasher. Chlorides must not exceed 50 ppm.
High iron levels in the water supply can cause staining and may require
an iron filter. High chloride levels in the water supply can cause pitting and may
require a chloride removal system. Contact you local water treatment professional
for proper water treatment.
Sediment may require a particulate filter. Dissolved solids may require water treatment
such as a water softener, reverse osmosis system, etc. Contact your local water treatment
professional for proper water treatment.
If an inspection of the dishwasher or booster heater reveals lime build-up after the equipment
has been in service, water treatment is recommended. If a water softener is already in place,
ensure there is a sufficient level of salt. Contact your Hobart Service office for specific
recommendations.
NOTE: For CL-VL models, damage to heat pump system due to improper water quality may
not be covered under Hobart warranty.
Water Supply Connections
The plumber who connects this machine is responsible for making certain that both water
and steam lines are THOROUGHLY FLUSHED OUT BEFORE connecting to the dishwasher.
This ‘‘flush-out’’ is necessary to remove all foreign matter, such as chips (resulting from
cutting or threading of pipes), pipe joint compound from the lines or, if soldered fittings are
used, bits of solder or cuttings from the tubing. Debris, if not removed, may lodge in the
dishwasher's plumbing components and render them inoperative. Manual valves or solenoid
valves found defective by foreign matter and any expenses resulting from this debris are
NOT the responsibility of the manufacturer and associated repair costs are not covered
under warranty.
CL-BAS models require a single incoming hot water
supply. CL-DWR and CL-ADV models require a hot
and a cold water supply. CL-VL models require a single
cold-water supply. Use 1/2" minimum I.D. pipe size for the
incoming water supply line(s) to the machine (Fig. 5).

Required flowing water pressure to the dishmachine is 20 to 65 PSIG. If flowing pressures
higher than 65 PSIG are present, a pressure-regulating valve must be installed in the water
line to the dishmachine (by others). If flowing pressure is less than 20 psi, improper machine
operation may result. All CL models are equipped with a pumped rinse system; therefore,
a water pressure gauge is not required and is not supplied with the machine.
The water pressure regulator must have a relief bypass. Failure to use
the proper type of pressure regulator may result in damage to the unit.

GAS CONNECTION (When Machine is Equipped with Gas Tank Heat)
Check the gas data plate attached to the dishwasher on the side of the control box or refer
to the tag attached to the gas burner tubing for the type of gas to be used. All machines are
shipped configured for natural gas. If conversion to LP gas (propane) is required, a conversion
kit with instructions is supplied and must be installed before the machine is operated.
The burner is not adjustable. If flowing gas pressure is above 7" W.C. (natural gas) or 11" W.C.
(propane gas), an additional regulator valve (by others) must be installed in the supply line.
Static incoming line pressure should not exceed 14.0" W.C. for either propane or natural gas.
The gas supply line to the dishwasher must be provided with a shutoff valve per code. The appliance and its gas connections must be leak tested before
placing the appliance in operation. Use soapy water for leak tests. DO NOT use an
open flame.
The installation must conform with local codes, or in the absence of local codes, with the
National Fuel Gas Code, ANSI Z223.1 (latest edition), available from the American Gas
Association, Inc., 1515 Wilson Blvd., Arlington, VA 22209. In Canada, comply with CAN/
CSA B149.1 and CSA C22.1 (latest editions).
NOTE: For gas line pipe connections, use Loctite 565, Hobart part number 546292, or a
flexible sealant suitable for use with Natural and Propane Gases.
• The appliance and its individual shutoff valve must be disconnected from the gas supply
piping system during any pressure testing of that system at test pressures in excess of
1
/2 psig (3.45 kPa).
• The appliance must be isolated from the gas supply piping system by closing its individual

Failure to follow this procedure may damage the gas valve.
Gas heat machines must be provided with a means to exhaust the
flue gases to the exterior of the building.
Refer to Venting Requirements on pages 11 – 14.
The dishwasher must be installed so that the flow of combustion and ventilation air will not
be obstructed. Ensure that no electrical cables or plumbing are routed over the gas flue
area. Adequate clearances for air openings into the combustion chamber must be provided.
Make sure there is an adequate supply of make-up air in the room to allow for combustion
of the gas at the burner(s).
– 10 –
Keep the appliance area free and clear from all combustible substances. Do not obstruct
the flow of combustion and ventilation air. The dishwasher must have a minimum clearance
from combustible construction of 3" at the rear and 0" at the sides. A clearance of 23" must
be provided at the front and 20" at each end of the dishwasher for servicing and proper
operation.
The burner is ignited automatically by solid-state electronic circuitry. There is no pilot light.
Gas flow is regulated by the temperature control circuit.
VENTING REQUIREMENTS
For CL-VL models, no pant leg duct or canopy hood venting is required. Ensure dish room
HVAC system is adequately sized to handle dish machine heat dissipation (latent and sensible
heat). No HVAC supply or return grills to be installed within 24” of heat pump assembly.
NOTE: For machines equipped with gas tank heat, a connection point (APS1 and APS2) is
provided for a vent fan interlock switch to prevent the flow of gas if air flow is not detected
in the vent system. Normally closed switch to be provided and installed by others.
Type II Canopy Hood
Most commercial dishwashers must be provided with external venting per local codes. The
exception is electric or steam heat machines operating in the chemical or low temperature
sanitizing mode where the existing room ventilation will compensate for the vapors produced.
The local authority has final jurisdiction over this matter.
Venting can be provided by either a canopy hood over the whole machine (Fig. 11) or by
the pant-leg duct connection (Fig. 12).
A Hobart CL-Series dishwasher equipped with gas tank heat is not provided with a flue collar
connection and is not intended to have the flue directly connected to a ventilation system.
However, the products of combustion must be vented to the outside air. Exhaust air must
not be vented into a wall, a ceiling, or a concealed space of a building. A vent hood over the
entire dishwasher (Fig. 11) can be employed to vent both the moist air from the dishwashing
chamber and the flue gases from the gas heater. The volume of flue exhaust required for
venting moist air and flue gases using a single vent hood over the entire dishwasher must
be calculated using the Exhaust Flow Requirements on page 14.
A Type II canopy hood is recommended. A factory-built commercial exhaust hood may be
listed as conforming to Underwriters Laboratory's Standard 710 titled, Exhaust Hoods for
Commercial Cooking Equipment. Hoods must be installed according to the manufacturer's
instructions. Makeup air must be provided so that the exhaust flow rate results in a positive
building pressure in the room where the unit is located (more outside air than exhaust air).
Factory-built hoods not tested to UL Standard 710 and custom built hoods must comply with
the following specifications: They must be built from stainless steel, 0.022" [No. 24 Gage]
minimum thickness, or copper sheet weighing at least 24 ounces per square foot; the hood
must be secured in place by noncombustible supports and the hood must meet the Exhaust
Flow Requirements on page 14.

Pant-Leg Vent Connections
Gas heat machines must be provided with a means to exhaust the
flue gases to the exterior of the building.
Pant-Leg duct connectors (Fig. 12) alone DO NOT provide ventilation for the gas flue at
the rear of the machine. A mini-vent hood (Fig. 13) must be used or a canopy type hood
may be used (Fig. 11).
Moist air escapes from each end of the conveyor type dishwasher. The recommended
exhaust requirement is 200 CFM at the entrance end of the dishwasher and 400 CFM at
the discharge end. Optional vent hoods or extended hoods may be provided at each end
of the machine. Sufficient make-up air must be provided so the exhaust flow results in a
positive building pressure in the room in which the unit is located (more outside air than
exhaust air). Hoods are provided with 4" x 16" vent connectors with vent dampers which
allow adjustment during installation. Typical construction is for 'Pant-Leg' hood connections
to the 4" x 16" vent connectors (Fig. 12). Vent stacks must be watertight and fit inside the
vent connector openings.
If using the 'Pant-Leg' duct, a mini-vent hood (Fig. 13) must be used to vent the flue gases
on machines using gas heat. The mini-vent hood must be positioned a minimum of 18"
above the flue exit at the rear of the dishwasher and connected to existing duct work. The
volume of flue exhaust in the mini-vent hood should not exceed 200 CFM.
In either case, if a powered means of exhaust is used, an electrical interlock must be
provided (supplied and installed by others) to allow the flow of gas to the dishwasher burner
only when the exhaust system is in operation.
For more information, refer to the National Fuel Gas Code, ANSI Z223.1, NFPA54. In all
cases, local codes will prevail.

Exhaust Flow Requirements
The following is based on the 2018 International Mechanical Code (IMC):
The flow of air required for a vent hood is based on the linear length of the face of the hood,
measured along the front side, parallel with the front of the appliance (refer to LENGTH in
Fig. 14). The minimum net air flow for Type II hoods used with dishwashers is 100 CFM
per linear foot of hood length. Simply multiply the hood's length, in feet, times 100 CFM to
obtain the required flow rate.
Subtract make-up air flow supplied directly to a hood cavity, from the total exhaust flow rate
of the hood, if applicable.
For hood designs not covered by these calculations consult the latest edition of the IMC or
other local codes.

Motor Rotation — Three-Phase Only
Before placing a three-phase machine into service, check to verify that the
pump motor(s) rotates in the correct direction. Incorrect rotation will result in unacceptable
performance.
To check the pump motor's rotation:
Close the machine doors, press POWER on the controls and allow the machine to fill. When
the machine is completely filled, press POWER to turn the machine off.
Disconnect the electrical power to the machine and follow
lockout / tagout procedures. There may be multiple circuits. Be sure all circuits are
disconnected.
Remove the lower front panel below the doors. Reconnect the electrical power to the
machine, being careful not to touch any uninsulated electrical parts exposed by removing
the front panel. Press START/ENTER on the controls and verify the pump motor rotation
by observing the fan located at the top of the motor and ensure it matches the direction of
the arrow located on the front of the motor.
If the rotation of the pump motor is correct, press POWER to turn the machine off.
DISCONNECT ELECTRICAL POWER SUPPLY to the machine, and replace the front
panel.
If the pump motor(s) does not rotate in the proper direction, DISCONNECT ELECTRICAL
POWER SUPPLY to the machine. Reverse any two of the incoming power supply leads to
the TB1 terminal block located in the control box on top of the machine. If the machine was
converted to a dual or multiple point electric connection configuration, also reverse any two
of the incoming power supply leads to the other service connection(s).
Reconnect the electrical power to the machine. Re-check the pump motor's rotation.
If the rotation of the pump motor is correct, press POWER to turn the machine off. DISCONNECT
ELECTRICAL POWER SUPPLY to the machine. Replace the lower front panel.
Optional Equipment Control Connections
Electrical and grounding connections must comply with the applicable
portions of the National Electrical Code, NFPA 70 (latest edition) and/or other local
electrical codes.
Disconnect the electrical power to the machine and follow lockout/
tagout procedures. There may be multiple circuits. Be sure all circuits are disconnected.
Detergent Feeder
The maximum rating for a detergent dispenser connected to DPS1 and DPS2 (located on TB5) is
1.5 amps at line voltage. Refer to Chemical Feeder Installations, page 9.
Rinse Aid Feeder and/or Chemical Sanitizer Feeder
The maximum rating for a rinse aid dispenser and/or chemical sanitizer feeder connected
to RPS1 and RPS2 (located on TB5) is 1.5 amps at line voltage. Refer to Chemical Feeder
Installations, page 9.
– 15 –
Vent Fan Control
The maximum rating for a vent fan connected to VFC1 and VFC2 (located on TB5) is 1HP
@ 120VAC, 2.5HP @ 240VAC.
For machines equipped with electric or steam tank heat, the vent fan control circuit will turn
the roof exhaust fan on when the pump motor(s) starts and off after a pre-set time once
the final rinse turns off, eliminating the need for a separate switch on the wall. The factory
setting for the vent fan control time delay is 5 minutes. This time can be adjusted from 0
minutes to 999 minutes in the Manager Menu. Refer to Programming, page 30, to adjust
the vent fan control time delay parameter.
For machines equipped with gas tank heat, the vent fan control circuit will turn the roof exhaust
fan on and off with the power on the dish machine, eliminating the need for a separate switch
on the wall. When this circuit is utilized, the exhaust fan on the roof will turn on when the
power button on the CL dish machine is pressed turning the dish machine on and the fan
will turn off when the power button is pressed turning the dish machine off.
The dish machine does not supply any voltage thru this circuit. It is a controlling circuit
utilizing a dry contact. A hot wire from the roof fan control connects to one of the VFC
terminals located on the TB5 terminal block in the CL control box located on top of the unit
and a second wire connects to the second VFC terminal and wires to the roof fan control
completing the circuit. The dish machine will then close and open this circuit as it is powered
on and off, which will turn the roof exhaust fan on and off with the dish machine.
External Booster Connection
BSTR1 and BSTR2 contacts (located on TB5) are provided to control (on/off) an external
booster heater. 120VAC @ 0.15 amps is provided when the dish machine is powered on
to control the external booster switching circuit. Refer to the Non-Booster Conversion
Instructions (F-46016).

DISHWASHING
After the machine has filled, start the pumps by pressing the WASH button on the HMI (Fig.
24) or by inserting a rack into the machine.
The machine will operate only if the tanks have filled to the proper level and all doors are
closed. Press the STOP button on the HMI to stop the conveyor motor and pumps.
Pre-scrap the dishes thoroughly to remove large food particles and debris. DO NOT use
steel wool on ware that is to be loaded into the dishwasher.
Stack dishes in the racks. Do not stack dishes one on top of another, as water must have free
access to both sides of every dish. Stand plates and dishes up edgewise (Fig. 25). Cups,
glasses and bowls should be inverted in an open-type rack (Fig. 25) or a compartmented
rack. Silverware and other small pieces may be scattered loosely over the bottom of an opentype, flat-bottom rack. To minimize splash, position trays in the rack in the same direction
as the motion of the conveyor (Fig. 25).
DO NOT attempt to wash large items (pots, pans, trays, etc.) without first checking to make
sure they will fit through the machine opening. Such large items must not be washed in this
dishwasher unless they will easily pass through it.
DO NOT allow foreign objects to enter the dishwasher, especially metallic contaminants.

Fig. 25
When one rack has been loaded, slide it part way into the machine until the conveyor dogs
catch the rack. Start inserting another rack when the previous rack has completely passed
the curtain at the load end. The operation of the dishwasher is automatic. When a rack
enters the machine, the pumps and conveyor automatically start. Each rack moves through
the scrapper (if equipped), the wash and the rinse zones,and then out onto the clean dish
table. The final rinse will activate after a set period of time after a rack enters the machine.
Allow dishes to drain and air-dry before removing the ware from the rack.
The conveyor dwell feature, standard, allows the operator to stop the conveyor in order to
wash heavily soiled dishes for a longer period of time. To enter the dwell mode, press the
menu button on the HMI to access the menus. Using the arrows, scroll down to LOGIN
and enter code 1001 to access the manager menu. Use the arrows to scroll until DWELL is
highlighted and then press the enter button. Select ENABLE to start the DWELL cycle. To
stop the DWELL cycle, reenter the menu and select DISABLE or press the STOP button.
If a rack jams or if the load becomes excessive, an overload mechanism shuts off the
conveyor drive motor and displays ‘Conveyor jam. Unload rack and check for jam.’. Open
the doors and remove the jam. After the jam is cleared, close the doors and press the Enter
button. Press the WASH button to restart the dishwasher.
Tank temperatures are shown on the display (Fig. 24) when the machine is in operation.
The final rinse temperature displays – – – until a rack is in the rinse zone; then, the final rinse
water temperature displays. After the ware exits the rinse zone, the final rinse temperature
display returns to – – – .
– 24 –
Pot and Pan Mode
The pot and pan feature, standard on all CL models, allows the operator to wash heavily
soiled pots and pans by indexing the racks thru two pre-set wash zones for a specified
amount of time. Press the POT & PAN button located on the HMI (Fig. 24) to enter the pot
and pan mode. Insert a rack into the machine. Each rack will index twice thru the wash
zone by the pre-set time. The machine will return to normal operation by pressing the POT
& PAN button or the STOP button, or if the Auto Timer times out.
Optional Table Limit Switch
If a rack reaches the end of the unload table and trips the table limit switch, the conveyor
shuts off. The display alternates between the tank names and ‘Unload rack’. After the rack
is removed and the table limit switch resets, normal operation of the dishwasher resumes.
NOTE: Table limit switch must be Enabled in the Manager Menu when installed. Refer to
the Manager Menu programming, page 30.
Auto-Timer
To conserve energy, if no rack enters the machine for a preset amount of time, the auto
timer counts down and the pumps and conveyor shut off. The tanks continue to heat, and
tank temperatures display. To resume operation, insert a rack or press the WASH button.
NOTE: The auto timer shut off setting is preset from the factory at 1 minute. You can adjust
the setting from 1 to 360 minutes (1-minute increments). Refer to the Manager Menu
programming, page 30.
