GE Commercial Gas and Electric Dryers have a

Rating Plate located on the front inside door

opening at the top right. It lists the Model Number,

UL listings, and individual product serial number.

You can see the rating plate by simply opening the

dryer door.

CAUTION!: Always disconnect appliance from

power prior to servicing to avoid shock hazard.

A mini-manual is provided inside the control panel

and has basic service information. On the back

side of the mini-manual is the product schematic,

which is valuable in troubleshooting any problems.

Resistances, voltages, and wiring colors are

shown and can be used with a volt-ohm meter to

check circuitry, and components.

The illustrations on the right provide graphic

information on how to access the mini-manual by

removing (4) T-20H Torx screws from the top of

the control panel and rolling it over on the top of

the dryer. The second illustration shows mini-

manual location, as well as SmartCard reader

access.

FEATURES

GE Commercial Laundry clothes dryers

DNCJ440E/GA0W (equipped with a BridgePoint

Card reader), and DNCK440E/GA0W (equipped

with ESD Card reader) provides new technology

and flexibility to the proven GE dryer platform.

These two systems provide the Commercial Laun-

dry operators with the ability to control pricing,

usage, and a multitude of functions, along with

audit functions for successful operation control

including activity reports.

Laundry Logic Management Software provides full

audit/transactional records displayed in 30 reports.

Theft and vandalism is greatly reduced by removing

cash from the dryer. Collection activities are re-

duced increasing productivity.

End users benefit because all the information is

stored on a card that retains all necessary usage

information. In both units a central reader station is

located at the Laundry site, the user inserts money

and the card is encoded to provide the service level

required by the user. The card is then inserted into

the dryer reader port, and the cycle is selected by

the user and the card is adjusted to charge for

usage.

The user can then replenish their card for the next

usage at the ESD Value Transfer Machine or VTM,

for BridgePoint the SmartLaundryTM Cash2Card

Value-Add Terminal (for all options contact

BridgePoint at 1-800-562-5875, or ESD at 1-800-

523-1510, ext. 104) for more information on termi-

nals. The product warranty specifies that the Card

Reader is serviced by the readers’ original equip-

ment manufacture, readers are available and listed

as GE Part #’s for the following models:

DNCJ440E/G BRIDGEPOINT READER

WH12X10217, and

DNCK440E/G

ESD READER

WH12X10218.

The Keypad electronic Card Reader models have

Field Service Diagnostics mode, which records

certain faults and retains them for review by the

servicer. A cycle progession mode can also be

enabled to make a check of normal component

operation.

The durable electronic controls replace timers and

analog buttons with membrane keypads, and

functions with printed PC board, onboard trans-

former and programmed logic.

INSTALLATION HIGHLIGHTS

It is IMPORTANT to read and understand the

complete installation instructions for your GAS or

ELECTRIC Commercial SmartCard dryers. The

installation highlights will cover exhausting tips,

gas line installation tips, and electric dryer hookup

requirements. Full comprehensive installation

instructions for your particular model is shipped

with every dryer. FOR QUESTIONS ON INSTAL-

LATION, CALL: 1-800-626-2003.

A good installation makes for good performance

and consist of the following steps as outlined in

your installation instruction shipped with the

appliance.

STEP 1- Prepare the area and exhaust for instal-

lation of new dryer.

STEP 2- Check and make sure the existing exter-

nal exhaust is clean and meeted the installation

specifications.

STEP 3- Remove the foam shipping pads.

STEP 4- Move the dryer to the desired location.

STEP 5- Connect powersupply.

STEP 6- Connect the external exhaust.

STEP 7- Level your dryer.

STEP 8- Check the operation of the power supply

and venting.Check the installation instruction for

special installation for Alcove or Closet, Bathroom

or Bedroom, Mobile or Manufactured Home, for

side and bottom exhaust. They are completely

covered in the product installation instructions.

FOR YOUR SAFETY:

WARNING

Use only rigid metal or flexible metal 4” diameter

ductwork for exhausting to the outdoors. Never

use plastic or other combustible, easy to puncture

ductwork.

This appliance must be properly grounded and

installed per the appliance installation instructions

shipped with every appliance.

Do not install or store appliance in an area where

it will be exposed to water and/or weather.

Install the dryer where the temperature is above

500F. for correct operation of dryer controls.

EXHAUSTING:

The MOST IMPORTANT element to good perfor-

mance is VENTING the dryer. With out sufficient

airflow dry times will be longer and linting will

develop.

If you are installing in an existing wall duct make

sure that you make sure the internal duct opening

is clear and that the hood damper opens and

closes freely.

Minimum clearance to combustible surfaces and

for air openings are: 0 in. clearance both sides and

1 in. rear. Consideration must be given to provide

adequate clearance for installation and service.

REMOVE LINT FROM WALL EXHAUST

PREPARING FOR INSTALLATION OF NEW

DRYER

EXHAUSTING:

NOTE: The correct exhaust installation is

YOUR RESPONSIBILITY.

Problems due to incorrect installation are NOT

covered in the warranty.

The MAXIMUM ALLOWABLE length of the ex-

haust system depends upon the type of duct,

number of turns, the type of exhaust hood (wall

cap), and all conditions noted below. Both rigid

and flexible metal are shown in the chart below.

EXHAUST SYSTEM CHECK LIST

HOOD OR WALL CAP

-Terminate in a manner to prevent back drafts or

entry of birds or other wildlife.

-Termination should present minimal resistance to

the exhaust air flow and should require little or no

maintenance to prevent clogging.

-NEVER install a screen in or over the exhaust

duct. This could cause lint build up.

-Wall caps must be installed at least 12 in. above

ground level or any other obstructions with the

opening pointing down.

-If roof vents or louvered plenums are used, they

must be equivalent to a 4-in. dampened wall cap

in regard to resistance to air flow, prevention of

back drafts, and maintenance requied to prevent

clogging.

SEPARATION OF TURNS:

-For best performance, separate all turns with at

least 4 ft. of straight duct., including distance

between last turn and exhaust hood.

TURNS OTHER THAN 900

-One turn of 450or less may be ignored

-Two 450 turns should be treated as one 900 turn.

-Each turn over 450 shold be treated as one 900

turn.

SEALING OF JOINTS

-All joints should be tight to avoid leaks. The male

lend of each section of duct must point away from

dryer.

-Do not assemble the ductwork with fasterners

that extend into the duct. They will serve to collect

lint.

-Duct joints can be made air tight by wrapping the

overlapped joints with duct tape.

-Horizontal runs should slope down toward the

outdoors 1/2 in. per foot.

INSULATION:

Duct work that runs through an unheated area or

is near air conditioning, should be insulated to

reduce condensation and lint build-up.

WARNING! - TO REDUCE THE RISK

OF FIRE OR PERSONAL INJURY:

-Exhausting the dryer to the outdoors is strongly

recommended to prevent large amounts of moisture

from being blown into the room.

-Use only metal duct.

-Do not terminate exhaust in a chimney, any gas vent,

under an enclosed door (crawl space), or into an

attic. The accumulated lint could create a fire

hazard.

-Provide an access for inspection and cleaning of the

exhaust system, especially at turns. Inspect and

clean at least once a year.

-Never terminate the exhaust into a common duct with

kitchen exhaust. A combination of lint and grease

could create a fire hazard.

-Do not obstruct incoming or exhausted air.

INSTALLATION HIGHLIGHTS/VENTING

The dryer comes ready for rear exhausting. Refer

to your installation instructions if space is limited

and you need to exhaust from the sides or bottom

of cabinet.

An example of standard rear exhaust vented at

floor level is shown below.

INSTALLATION HIGHLIGHTS/LEVELING

It is also important that you take the time to level

the dryer. It helps to remove vibration, “walking”,

and improves clothing turn over rate for improved

drying. Illustration below show the correct method

to level the dryer.
