Installation, Operation and Care Of

CLeN-SERIES DISHWASHERS

SAVE THESE INSTRUCTIONS

GENERAL

CLeN 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nalrinseareactivated

bytheinsertedracktoenergizethespecicwashorrinseactionneeded.TheCLeN-series machines

are offered in optional lengths, sections, features, and provide different speeds to meet productivity

and performance requirements. All CLeN-Series Dishwashers have electronic controls with digital

temperature displays.

The CLeN-EGR models have a drain water energy recovery system which includes drain water

tempering and all of the standard features of the CLeN. They use a heat exchanger to capture the

energyfromthedrainwaterandpreheatincomingcoldwaterforthenalrinse.TheCLeN-EGR

units are only available in hot water sanitizing mode, three phase, and come standard with a built-in

30kWboosterheater,whichisdesignedtomaintainnalrinsetemperatureof180°Fwithaminimum

incomingcoldwatertemperatureof55°F.

The CLeN-ADV models have an Automatic Soil Removal (ASR) system and include all of the

standard features of the CLeN-EGR. 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 CLeN-ADV-Series machines are only available in hot

water sanitizing mode, electric heat, three phase voltage supply, and come standard with a 30KW

built-in booster heater. The CLeN-ADV models are not available with a corner scrapper unit (CLCS).

The CLeN-VL models have a ventless system and include all the standard features of the CLeN

Basemodels.The ventlesssystemuses energyefcientheat-pumptechnology combined with

energy recovery to remove the need for direct venting while providing auxiliary heat to the wash

tank. The CLeN-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 30KW

built-in 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. CLPS 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. Either electric, gas, or steam tank

heatisspecied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 CLeN-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 (CLCS models) puts a Power Scrapper in the corner location at the load

end of your machine, combining right angle entry with a scrapper section.

– 5 –

CHEMICAL SANITIZING

CLeN machines can be converted to operate with low-temperature sanitizing mode (with

the use of chemical sanitizers). Refer to Sanitation Mode programming instructions on

page 36. NOTE: Chemical sanitization is not available on the CLeN-EGR, CLeN-ADV, or

CLeN-VLmodels.

Hot water sanitizing mode is designated by "High Temp." on the display when the machine

is turned on. Low-temperature or chemical sanitizing mode is designated by "Low Temp."

on the display when the machine is turned on.

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 CLeN-VL models, ventless heat pump assembly ships separate on its own skid.

Priortoinstallation,verifythattheelectricalserviceagreeswiththespecications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(overowtubeorstandpipe,

splash shields, curtains, extra wash arm caps, and literature envelope with instructions and

chamber hole plug kit) from inside the dishwasher. For CLeN-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 CLeN Ventless Installation manual, F-45820.

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ttedintothedishwasher(Figs.1,2&3).Usesiliconesealantbetween

table and lip of tank to prevent leakage. Rack track height should be from 1/4 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 the machine, but not from the scrapping area.

NOTE: Thedishwashermustbeinitsnalposition,adjustedforproperheightandproperly

leveled before table assembly and plumbing connections are made.

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efcientuseofthis

equipment will also vary depending on the local water conditions. Ask your municipal water

supplierfordetailsaboutlocalwaterspecicspriortoinstallation.

Recommended water hardness is 3 grains of hardness per gallon or less. Chlorides must not

exceed 30 parts per million. Water hardness above 3 grains per gallon should be treated by

a water conditioner (water softener or in-line 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.

NOTE: For CLeN-VL models, damage to heat pump system due to improper water quality

may not be covered under Hobart warranty.

Sediment,silica,chloridesorotherdissolvedsolidsmayrequireparticulateltrationorother

water treatment.

If an inspection of the dishwasher or booster heater reveals lime buildup after the equipment

has been in service, in-line water treatment is recommended. Contact your local Hobart

Serviceofceforspecicrecommendations.

PLUMBING CONNECTIONS

Plumbing connections must comply with applicable sanitary, safety

and plumbing codes.

The plumber who connects this machine is responsible for making certain that both water

and steam lines are THOROUGHLY FLUSHED OUT BEFORE connecting to any manual

valve or solenoid valve.

This‘‘ush-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ttingsare

used, bits of solder or cuttings from the tubing. Debris, if not removed, may lodge in the

valves 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.

Drain Connection

Thecommondrainforthetank(s)requiresonlyoneconnectiontotheoordrain.Thedrain

can be connected at either end. A pipe plug is provided for the opposite end. NOTE: For

CLeN-EGR and CLeN-ADV models, the factory drain plumbing may need to be relocated to

opposite side of drain body (Fig. 5). Connect the drain (Fig. 6) through a trap to the sewer

using2"NPTpipe.Ifagreasetrapisrequiredbycode,itshouldhaveaminimumow

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).

Keep the appliance area free and clear from all combustible substances. Do not obstruct

theow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owisregulatedbythetemperaturecontrolcircuit.

VENTING REQUIREMENTS

For CLeN-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.

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naljurisdictionoverthismatter.

Venting can be provided by either a canopy hood over the whole machine (Fig. 12) or by

the pant-leg duct connection (Fig. 13).

A Hobart CLeN-Seriesdishwasherequippedforgastankheatisnotprovidedwithauecollar

andisnotintendedtohavetheue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. 12) can be employed to vent both the moist air from the dishwashing chamber and

theuegasesfromthegasheater.Thevolumeofueexhaustrequiredforventingmoist

airandue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owrateresultsinapositive

Pant-Leg Vent Connections

Gas heat machines must be provided with a means to exhaust the

ue gases to the exterior of the building.

Pant-Leg duct connectors (Fig. 13) alone DO NOTprovideventilationforthegasueat

the rear of the machine. A mini-vent hood (Fig. 14) must be used or a canopy type hood

may be used (Fig. 12).

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.Sufcientmake-upairmustbeprovidedsotheexhaustow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.13).Ventstacksmustbewatertightandtinsidethe

vent connector openings.

Ifusingthe'Pant-Leg'duct,amini-venthood(Fig.14)mustbeusedtoventtheuegases

on machines using gas heat. The mini-vent hood must be positioned a minimum of 18"

abovetheueexitattherearofthedishwasherandconnectedtoexistingductwork.The

volumeofue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 pro-

videdtoallowtheow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 2015 International Mechanical Code (IMC):

Theow 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.15).Theminimumnetairow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owrate.

Subtractmake-upairowsupplieddirectlytoahoodcavity,fromthetotalexhaustow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.

ELECTRICAL CONNECTIONS — DISHWASHER

Electrical and grounding connections must comply with the applicable

portions of the National Electrical Code, ANSI / 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.

Connect a permanent electrical power supply to the terminal block in the control box on top

of the machine. Refer to the machine data plate for proper connection information and the

electrical diagram located inside the control box cover.

Motor Rotation — Three-Phase Only

Before placing a three-phase machine into service, check to verify that the

conveyor motor rotates in the correct direction. (The control box is pre-wired at the factory

so that all motors are phased together. If the conveyor motor rotation is correct, the pump

motors will also be correct.) Incorrect rotation will result in unacceptable performance.

To check the conveyor motor's rotation:

Closethemachinedoors,pressPOWERonthekeypadandallowthemachinetoll.When

themachineiscompletelylled,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 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 keypad and verify proper motor rotation, as follows:

The conveyor motor and clutch must rotate counterclockwise for machines with right-to-left

operation, and clockwise for machines with left-to-right operation.

If the rotation of the conveyor motor is correct, press POWER to turn the machine off.

Disconnect electrical power to the machine, and replace the front panel.

If the conveyor motor does not rotate in the proper direction, disconnect the electrical power

to the machine. At the machine control box on top of the machine, reverse any two of the

incoming power supply leads, either the leads to the entire machine, or the leads to the

motor and controls if they are wired independent of the heaters. Do not simply reverse the

leads to the conveyor motor.

Reconnect the electrical power to the machine. Re-check the conveyor motor's rotation.

The conveyor motor and clutch must rotate counterclockwise for machines with right-to-left

operation, and clockwise for machines with left-to-right operation.

If the rotation of the conveyor motor is correct, press POWER to turn the machine off.

Disconnect the electrical power to the machine. Replace the top cover to the control box,

and replace the 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 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 is 1.5 amps at line voltage. Refer to Chemical Feeder Installations, page 9.

Vent Fan Control (Not Available on CLeN-VL models)

The maximum rating for a vent fan connected to VFC1 and VFC2 is 1HP @ 120VAC, 2.5HP

@ 240VAC.

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 CLeN 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 5TB terminal block in the CLeN control box 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 open and close this circuit as it is powered on and off,

which will turn the roof exhaust fan on and off with the dish machine.

CLeN-EGR AND CLeN-ADV ENERGY RECOVERY SETUP

Disconnect the electrical power to the machine and follow lockout/

tagout procedures. There may be multiple circuits. Be sure all circuits are disconnected.

Set up procedures must be performed after hot and cold water connections

have been completed, tank(s) are full, and machine is ready for operation.

1. Turn main power to machine OFF at customers disconnect.

2. Ensure tank(s) are empty. If not empty, pull drain lever(s) and allow tank(s) to drain.
