GENERAL SAFETY FIRST Your safety and the safety of others is very important. We have provided many important safety messages in this Job Aid and on the appliance. Always read and obey all safety messages. This is the safety alert symbol. This symbol alerts you to hazards that can kill or hurt you and others. All safety messages will follow the safety alert symbol and either the word “DANGER” or “WARNING.
WARNING IMPORTANT Electrostatic Discharge (ESD) Sensitive Electronics ESD problems are present everywhere. ESD may damage or weaken the electronic control assembly. The new control assembly may appear to work well after repair is finished, but failure may occur at a later date due to ESD stress. • Use an antistatic wrist strap. Connect the wrist strap to the green ground connection point, or to an unpainted metal surface in the appliance.

INSTALLATION INFORMATION WASHER INSTALLATION INSTRUCTIONS WARNING Electrical Shock Hazard Disconnect power before servicing. Replace all parts and panels before operating. Failure to do so can result in death or electrical shock. Check location where washer will be installed. Proper installation is your responsibility. Make sure you have everything necessary for correct installation.
If codes permit and a separate ground wire is used, it is recommended that a qualified electrician determine that the ground path is adequate. Do Not ground to a gas pipe. Check with a qualified electrician if you are not sure the washer is properly grounded. Do Not have a fuse in the neutral or ground circuit. A 120-volt, 60-Hz, AC-only, 15- or 20ampere fused electrical supply is required. (Time-delay fuse or circuit breaker is recommended.
INSTALLING THE WASHER 4. WARNING Excessive Weight Hazard Use two or more people to move and install washer. Failure to do so can result in back or other injury. 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. Removing the shipping strap is necessary for smooth operation.
6. 7. 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. 9. 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 in. (10.2 cm) with a wood block, or similar object.
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. 16. Check for level by placing a level on 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 side to side.
MONEY ACCEPTOR INSTALLATION If the coinslide is installed in the washer, it must be removed prior to changing the vend price. If the coinslide has not yet been installed, skip to step 6. 1. Unplug washer or disconnect power. 2. Remove meter case top access panel. 3. Remove any existing money acceptor if currently installed. If the current acceptor is a coinslide, unscrew the coinslide retaining bolt with a 5/16″ socket by turning counterclockwise, and remove the bolt.
6. Install the washer coinslide extension onto the coinslide using the screws packed with the coinslide kit. The vend price may now be adjusted from $.25 to $2.00 on a V8 coinslide as needed. To change the vend price, follow steps 7-14. 7. Set the coinslide and extension assembly on a level surface and remove the return spring(s) from the spring bracket. 8. Place coins in the coinslide of the proper vend amount (factory preset on coinequipped models is $1.
13. Reinstall the three insert retaining plate screws, flip the coinslide over, and reinstall unused inserts (up to 4 count). Reinstall the spring bracket and retaining screw. 18. Insert the coinslide retaining bolt from the meter case top access panel into the back of the coinslide, and hand tighten to start the threads prior to using any tools to avoid stripping the coinslide or retaining bolt threads. 14. Release the coinslide and reinstall the coinslide return spring(s) onto the spring bracket. 15.
SMART CARD INSTALLATION 7. WARNING Electrical Shock Hazard Disconnect power before servicing. Replace all parts and panels before operating. Failure to do so can result in death or electrical shock. T-15 Torx Screws 8. 9. 1. Unplug washer or disconnect power. 2. 3. Remove meter case top access panel. Remove any existing money acceptor if currently installed.
12. Close the console and replace the two Torx T-15 screws. 13. Install the card reader into the upper meter case opening. Push the card reader into the meter case, then lock it by pushing down slightly. Push Down To Lock Insert SMART Card Reader Into Top Slot 14. Install the card reader retaining screw included with the kit, or a standard coinslide retaining bolt. 15. Reconnect power and set the vend price on the set up card. 16. Snap the coin box cover plate over the coin box opening. 17.
THEORY OF OPERATION The Whirlpool High Efficiency Top Load Commercial Washer is the first top-loading washing machine to receive Energy Star® designations. The High Efficiency Top Load Commercial Washer is designed to successfully wash clothes with up to approximately 28% less water per load*. The washer uses a series of “spray rinses” rather than a “deep rinse,” as in other conventional washers. As water is sprayed onto the spinning clothes, they become saturated with water and detergent.
Two water levels allow efficient use of the washer for both large and small loads. Four wash/rinse temperature combinations help to provide the right washing conditions for a wide range of fabrics: Heavy (Hot/Cold), Regular (Warm/Warm), Permanent Press (Warm/Cold), and Colorfast (Cold/Cold). The High Efficiency Top Load Commercial Washer has the following unique components: • Automatic Temperature Control.
