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.

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.

ELECTRONIC CONTROL FIELD SERVICE
MODE
The Field Service Mode for the L3D Controls
allows the field service technician to test the input
and outputs of the control. It also allows the
technician to step through the test cycle to operate
the individual components of the dryer.
Field Service more can be entered via manual
entry by employing a special Service Mode card
(available to commercial laundry owners) into the
SmartCard reader.
Manual entry into the Field Service mode requires
the Model Selector harness group #12
(165D1349G012) GE PART #WD21X10068 for
Electric units, group #11 (165D1349G011) GE
PART #WD21X10030 for Gas units to be installed
into the L3D control. To do so, power down the
machine, remove the currently installed Model
Selector plug and set it aside. Insert the appropri-
ate Model Selector harness and re-apply power to
the machine.
The LED display will show Fd (Field Service
Diagnostics) when the service mode is entered.
When any keypad is pressed an audible beep will
occur for 0.5 seconds. The intial step is labeled
step “0”. The user entry into diagnostics causes
the control to display Fd, and all LEDs on the
keypads to light up. The next displays by the
control are Dryer type (GAS/ELECTRIC), memory
version number. The displays last for 0.5 seconds.
When the LED display goes off you may proceed
to the next step by pressing the PERM PRESS
keypad, or to go back to the previous display press
the DELICATES keypad.
Termination of the Diagnostics Mode can be
accomplished in three ways.
1. Unplug the dryer.
