To minimize a possible shock hazard, the cord must be plugged into a mating 3-prong ground­ing-type receptacle, which has been grounded in accordance with National Electrical Code (ANSI/NFPA 70), and all local and state codes.
If a mating outlet is not available, it is the personal responsibility and obligation of the customer to have a properly grounded 3-prong outlet installed by a qualified electrician.
Removing the shipping strap is necessary for smooth operation. If the shipping strap is not removed, the washer will make excessive noise.
1. Do not cut yellow strap. Pull yellow strap firmly, until completely removed from washer. There will be two cotter pins on the end of the shipping strap when it is pulled out of the washer. The electrical plug is attached to this shipping strap.
2. The shipping strap plug must be completely removed from the washer for the self-level­ing legs to be released. Save the shipping strap for use in step 7.
IMPORTANT: Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Do not modify the plug provided with the appliance. If it will not fit the outlet, have a proper outlet installed by a quali­fied electrician.

3. Insert a flat washer into each end of the in­let hoses. Check that washers are firmly seated in couplings.
4. Attach hose to bottom inlet valve opening first. Then second hose to top inlet. Tighten couplings by hand; then use pliers to make an additional two-thirds turn. Slide washer onto cardboard or hardboard before mov­ing across floor.
Inlets are plastic. Do not strip or crossthread.
6. Place hose clamp over washer drain con­nector. Push drain hose onto washer con­nector. Use pliers to open clamp and slide clamp over drain hose. Check for good fit.
7. Measure and mark a point approximately 16″ (40.6 cm) from the plug end of the shipping strap. Cut the shipping strap at this point.
5. Move washer close to final position. Put the “hooked” end of drain hose into the standpipe. Estimate length of drain hose needed when washer is in final position. Hose must be cut exactly to length so the “hooked” end is held tightly over edge of standpipe. If drain hose is too long, cut straight end of hose. (Do not cut the “hooked” end of drain hose.) Do not force excess length of drain hose down the standpipe. This could cause siphoning. See step 8.
40.6 cm
8. Put the “hooked” end of drain hose into the standpipe. Tightly wrap the shipping strap around the standpipe. Push plug into the nearest hole in the shipping strap. Check that hose is not twisted or kinked and is securely in place.

9. Before attaching water inlet hoses, run water through both faucets into a bucket. This will get rid of particles in water lines that might clog hoses. Mark which is the hot water faucet.
10.Attach bottom hose (inlet marked “H”) to hot water faucet. Attach top (inlet marked “C”) to cold water faucet. Tighten coupling to faucet by hand, then use pliers to make final two-thirds turn.
11.Prop up the front of the washer about 4″ (10.2 cm) with a wood block, or similar object. The block needs to support the weight of the washer.
12.Screw the locknut onto each foot to within 1″ (2.5 cm) of the base.
13.Screw the feet into the correct holes at the front corner of the washer until the nuts touch the washer. NOTE: Do not tighten the nuts until the washer is level, step 17.
14.Tilt washer backward and remove the wood block. Gently lower washer to floor. Move washer to its permanent location. Remove cardboard or hardboard from under washer.
15.Tilt washer forward raising back legs 1″ (2.5 cm) off of floor. To adjust rear leveling legs, gently lower washer to floor.

top of the washer, first side-to-side, then front-to-back.
17.If washer is not level, adjust the front legs up or down. Make final check with level. Best results are obtained when the washer is tilted 1/4 bubble toward the rear and level side­to-side. When washer is level, use wrench to turn nuts on front legs up tightly against washer base. If nuts are not tight against washer base, the washer may vibrate.
MOVING THE WASHER
To move the washer to a new location, perform the following steps:
1. Remove the front legs from the base of the washer.
2. Place both rear leveling legs in the upper position and tape them securely in place.
3. Apply tape to the side and bottom of the cabinet near the rear.
4. Open the washer lid, wedge a blanket be­tween the tub ring and the cabinet top to keep the tub from moving.
5. Move the washer to the desired location. Be careful not to drop the washer while using a hand truck.

DRYER EXHAUST REQUIREMENTS
WARNING
6. 4″ (10.2 cm) metal exhaust vent is required. Plan the installation to use the fewest num­ber of elbows and turns. Use 4″ (10.2 cm) vent clamps to secure the vent system.
7. A metal flexible vent must be fully extended and supported when the dryer is in its final position. DO NOT KINK OR CRUSH THE
VENT.
Fire Hazard Use a heavy metal vent. Do not use a plastic vent. Do not use a metal foil vent. Failure to do so can result in death or
fire.
1. Do not use a non-metal flexible vent, a metal vent that is smaller than four inches in diameter, or exhaust hoods with magnetic latches.
2. The dryer must be exhausted outdoors.
3. Do not exhaust the dryer into a gas vent, chimney, wall, ceiling, or the concealed space of a building.
4. Do not install flexible vent in enclosed walls, ceilings, or floors.
5. If using an existing exhaust system, clean the lint from the entire length of exhaust system. Make sure the exhaust hood is not plugged with lint. The exhaust system should be inspected and cleaned yearly. Replace any plastic or metal foil exhaust vent with rigid metal, or flexible metal vent.
8. A metal flexible vent must be completely open to allow adequate exhaust air to flow.
9. Allow as much room as possible when using elbows or making turns. Bend vent gradually to avoid kinking. Remove any excess flexible vent to avoid sagging and kinking that may result in reduced airflow. The exhaust outlet is located at the center of the bottom dryer back. The exhaust vent can be routed up, down, left, right, and behind the dryer, or straight out the back.

The maximum length of an exhaust system depends upon the type of vent used, the num­ber of elbows, and the type of exhaust hood. The maximum lengths for both rigid and flex­ible venting is shown in the chart below.
For exhaust systems not covered by the ex­haust length chart, see the Whirlpool Service Manual: “Exhausting Whirlpool Dryers,” Part No. 603197, which is available from your Whirl- pool parts distributor. Also refer to Section 8.
If a dryer is installed in a confined area, it must be exhausted to the outside, and provision made for enough air for combustion and venti­lation. Check governing codes and ordinances.
A 4″ (10.2 cm) outlet hood is preferred, how­ever, a 2 1/2″ (6.4 cm) outlet exhaust hood may be used. A 2 1/2″ (6.4 cm) outlet creates greater backpressure than other hood types. For permanent installation, a stationary ex­haust system is required.
2-13
Page 28
MULTIPLE DRYER VENT INSTALLATION
A main exhaust vent can be used for exhaust­ing a group of dryers. The main exhaust vent should be sized to remove 200 CFM of air per dryer.
Large-capacity lint screens of proper design may be used in the main exhaust vent if checked and cleaned frequently.
The room where the dryers are located should have makeup air equal to or greater than the CFM of all the dryers in the room.
An exhaust hood should cap the exhaust vent to prevent exhausted air from returning into the dryer. The outlet of the hood must be at least 12″ (30.5 cm) from the ground or anything else that may restrict flow of exhaust air. If an exhaust hood cannot be used, the outside end of the main vent should have a sweep elbow directed downward.
A Back-draft Damper Kit, #3391910, is avail­able from your Whirlpool dealer and should be installed in each dryer's exhaust vent to pre­vent exhausted air from returning into the dry­ers, and to keep individual exhausts in balance within the main exhaust vent. Unobstructed air openings are required.
Each exhaust vent should enter the main vent at an angle pointing in the direction of the airflow.
Vents entering from the opposite side should be staggered to reduce the exhausted air from interfering with the other vents. The maximum angle of each vent entering the main vent should be no more than 30 degrees. Keep air openings free of dry cleaning fluid fumes. Fumes create acids which, when drawn through the dryer heating units, can damage dryers and loads being dried. A clean-out cover should be located on the main exhaust vent for periodic cleaning of the exhaust system.

INSTALLING THE DRYER
WARNING
Explosion Hazard
Keep flammable materials and vapors, such as gasoline, away from dryer.
Place dryer at least 18 inches (45.8 cm) above the floor for a garage installation.
Failure to do so can result in death, explosion, or fire.
2. Place two of the cardboard corners from the carton on the floor in back of the dryer. Firmly grasp the body of the dryer, and gently lay it on its back on the cardboard corners.
3. Look at the ridges on one of the leveling legs for a diamond marking. That is how far the leg is supposed to go into the hole.
4. Start to screw the leveling legs into the holes by hand. (You can use a small amount of liquid detergent to lubricate the screw threads so it is easier to turn the legs.) Use a 1″ wrench or socket wrench to finish turning the legs until you reach the diamond mark, then stand dryer up on its feet.
NOTE: Slide the cardboard or hardboard un­der the dryer before moving it across any flooring, to avoid damaging the floor covering.
WARNING
Excessive Weight Hazard
Use two or more people to move and install dryer.
Failure to do so can result in back or other injury.
1. Remove the tape from the front corners of the dryer. Open the dryer and remove the literature and parts packages. Wipe the interior of the drum thoroughly with a damp cloth.
5. Move the dryer close to its final position. Remove the cardboard or hardboard from under the dryer.
At this time, proceed to either “Gas Dryers” or “Electric Dryers” to complete the installation.
2-16
Page 31
GAS DRYERS
1. Remove red cap from gas pipe.
2. Connect the gas supply to the dryer. For L.P. gas installations, be sure to use pipejoint compound that is resistant to the action of L.P. gas. If flexible metal tubing is used, be certain there are no kinks in the tubing.
3. If it is necessary to open the toe panel for service, use a putty knife to press on the toe panel locks, located at the top corners of the panel. Pull downward on the toe panel to open it. The toe panel is hinged at the bottom.
4. Open the shutoff valve in the gas supply line.
5. Use a non-corrosive leak detection fluid to check for leaks. Bubbles around connec­tions will indicate a leak.
NOTE: Never test for gas leaks with a flame.
6. If a leak appears, shut off gas valve controls and adjust connections. Then check con­nections again. Close toe panel. All con­nections must be wrench tightened.
NOTE: The dryer door must be closed for the dryer to operate. When the door is open, the dryer will stop, but the timer will continue to run. To restart the dryer, close the door, and push the START button.
7. Connect the exhaust vent system to the dryer exhaust outlet and the exhaust hood, using 4″ (10.2 cm) clamps. Use caulking to seal the exterior wall opening around ex­haust hood.
8. Carefully move the dryer into its final posi­tion. Place a level on top of the dryer, first side-to-side, then front-to-back. If the dryer is not level, adjust the legs up or down until it is level.
9. If the burner does not ignite and you can feel no heat inside the dryer, shut off the dryer for five minutes. Check to make sure that all of the gas supply valve controls are on, and that the electrical cord is plugged in. Repeat this five-minute test.
10.If the drying time is too long, make sure that the lint screen is clean, and there is no obstruction to airflow, (i.e. kinked venting, foreign material in vent, vent hood stuck closed, or vent tubes too long; see page 2-13).
11.Lift the service door up at the back and remove it from the metercase. Install the chosen money acceptor, as instructed in the appropriate money acceptor section of this Job Aid.

MONEY ACCEPTOR INSTALLATION
ADVANTECH models come from the factory without money acceptors installed. The end user must install the money acceptor or combi­nation of acceptors of their choice. Money acceptors are available in three basic varieties, coinslides, coindrops and SMART Cards. The ADVANTECH control can accept inputs from all of these devices.
The control can be configured to operate with­out a money acceptor, or have a coinslide/ coindrop with an auxiliary interface, connected (card reader) at the same time. With multiple money acceptor installations, some features of ADVANTECH may be limited by the acceptor's capabilities. For example, if a coinslide is used on a dryer, the top-off purchase option is lim­ited to the full amount of the coinslide.
Whirlpool does warranty the proper operation of the control system when external connec­tions are made as described within this docu­ment. External circuits may induce EMI (elec­tromagnetic interference) which could result in
improper operation of the control system. It is the responsibility of the money acceptor manu­facturer to insure proper operation of the aux­iliary interface device with the ADVANTECH control. Product modifications void the Whirl­pool warranty.
The money acceptor type installed must be programmed into the control either manually or through use of the ADVANTECH manage­ment software and the PDA. Additionally the vend-amount of the money acceptor must match the vend-price programmed into the control. For information on setting vend-price and the money acceptor type using ADVANTECH Management Software and Palm, consult the Software Service Manual, Part #8524743.
If the washer or dryer is to be used without the ADVANTECH Management Software and Palm, infrared (IR) functionality must also be disabled to prevent unauthorized access to the control settings.

AUXILIARY DEVICE OVERVIEW INSTALLATION, WASHERS AND FREESTANDING DRYERS
Auxiliary devices include but are not limited to SMART Card devices, remote monitoring sta­tions, Internet monitors, distributed money ter­minals and other transaction stations. Cur­rently the only commonly used auxiliary device is a SMART Card. As more devices become common, additional descriptions will be pro­vided.
If the Auxiliary device is a SMART card unit, the card acceptor can physically reside in the loca­tion normally used by a coinslide or coindrop mechanism. Alternately, a washer and dryer model is offered without a metercase (full width console model), but provides a mounting loca­tion in the console for a SMART Card reader.

Pin Function
1 DC Power Return 2 DC Power 3 No Connection 4 Signal Input 5 Signal Output 6 Signal Ground
NOTE: When the thermal fuse opens the con­trol must be replaced! Prior to installation of the new control all auxiliary devices should be checked per manufacturers testing procedures to prevent control failure. Additionally the water valve on washers and the bias heater circuits should also be tested (see “Component Test­ing” in section 5).
CARD READER CIRCUIT
The +5 VDC and DC circuit ground indicated below are isolated from the AC line by a UL Class II transformer. No connection to earth ground or cabinet ground is to be made by the coindrop circuit. If a circuit other than an opto beam interrupter is used, for example a micro­processor controlled unit, the circuits must remain electrically isolated from one another.
COINDROP CIRCUITS
AT P10 AND P11
Security is only provided by physical access to the auxiliary communications port. There are no security codes imposed between the con­trol and the auxiliary device. Therefore, the auxiliary device must provide for its own secu­rity layer of protection.
The auxiliary device connection on the control board features a power output enabling device to be connected to the control without requiring an external low voltage power source (extra transformer). This helps reduce the end user cost of such devices. The transformer contains an internal one-time use thermal fuse at the primary, which opens when current draw is greater than the 200-mA limitation. An open thermal fuse not only disables the entire auxil­iary power supply but also power to the control.

AUXILIARY DEVICE INSTALLATION, WASHERS AND FREESTANDING DRYERS
For the purpose of installation instructions the only auxiliary device detailed will be a SMART Card reader. The SMART Card reader on all models is connected to the auxiliary input. When a SMART Card reader is installed, the reader becomes the primary over the control, and the control assumes the secondary role, display codes are then driven by the card reader. Codes will vary between card manu­facturers. If a code is displayed in the reader other than codes listed in this manual, consult the maker of the card reader for additional information.
NOTE: When routing the harness from the card reader to the control, care must be taken not to bundle the card reader harness with the washer harness. If the two harnesses are bundled together, signal interference may oc­cur that would prevent proper card reader operation.

PRODUCT OPERATION
ADVANTECH SYSTEM OVERVIEW
ADVANTECH Product flexibility allows a single washer or dryer to accept multiple payment systems over the life of the product. This elimi­nates the need to purchase different SKUs based on money acceptance requirements.
ADVANTECH allows use of multiple money
acceptors, as well as Palm
and SMART Card accountability systems at the same time. All ADVANTECH
models come equipped with an auxiliary communications port for connecting SMART Cards, Ethernet boxes, Internet con­trols, or additional devices. ADVANTECH does not require that purchasers be tied to an appli­ance manufacturer’s proprietary card reader. The ADVANTECH open-architecture design allows the use of a card system that best meets the current business requirements to be in­stalled into the product.
Whirlpool ADVANTECH Commercial Laun­dry Products allow the use of a Palm handheld device, also referred to as a “Personal Digital Assistant” (PDA), for washer and dryer instal­lation and setup. This includes setting special vend-prices, washer and dryer software up­grades, and transferring data to and from a personal computer (PC). Information is set up on a PC using ADVANTECH Management Software, which is then used to download ADVANTECH Handheld Software to the Palm. The Palm uses an infrared light beam to communicate information contained in the Management Software to the washer and dryer.
Before downloading the Handheld Software to the Palm, Management Software must be installed and running on the PC. Passwords, machine setup, and Handheld Software are available within the Management Software. Detailed information about setup and installa­tion of the ADVANTECH Management Soft­ware is available in the Software Service Manual, Part #8524743. Additional ADVANTECH literature can be located in the “Literature Cross-Reference Chart” on page 1-9.
Commands for the Management Software in­stalled on the PC are entered by using the keyboard or mouse. Commands for the Handheld Software are entered into the Palm by tapping the appropriate menu on its screen, using a stylus that is provided with the handheld device. Occasionally you may be asked to
enter text into the Palm
using the Graffiti text characters, or the Palm keyboard. Additional information regarding the use of Graffiti text and the Palm keyboard can be found in the Palm Owner’s Manual.
