    1-2. IMPORTANT SAfETY INfORMATION To avoid risk of fire, electric shock, serious injury, or death when using your dryer, follow these basic precautions: 1. Read all instructions before using the dryer. 2. Install dryer according to Installation Instructions. Refer to the Grounding Instructions in the Installation Instructions for proper grounding of the dryer. 3. Do not dry articles that have been cleaned in, washed in, soaked in, or spotted with gasoline, drycleaning solvents, or other flammable or explosive substances. Vapors could ignite or explode. 4. Do not use the dryer to dry clothes which have traces of any flammable substance, such as vegetable oil, cooking oil, machine oil, flammable chemicals, thinner, etc., or anything containing wax or chemicals, such as mops and cleaning cloths. Flammable substances may cause the fabric to catch fire by itself. 5. Do not store or use gasoline or other flammable vapors and liquids near this or any other appliance. 6. Do not allow children to play on or in dryer. Close supervision of children is necessary when the dryer is used near children, a safety rule for all appliances. 7. Before the dryer is removed for service or is discarded, remove doors to drying compartment. 8. Do not reach into the dryer if cylinder is rotating. 9. Do not install or store the dryer where it will be exposed to water and/or weather. 10. Do not tamper with dryer controls. 11. Do not repair or replace any part of the dryer or attempt any service, unless specifically recommended in user- maintenance instructions or in published user-repair instructions that you understand and have skills to carry out, if you are a consumer. 12. To reduce risk of electric shock or fire, do not use extension cords or adapters to connect the dryer to electrical power source. 13. Use the dryer only for its intended purpose, drying clothes. 14. Always disconnect the dryer from electrical supply before attempting any service. Disconnect the power cord by holding the plug, not the cord. 15. Do not use heat to dry articles containing foam rubber or similarly textured rubberlike materials.

    22. Never operate the dryer with the guards and/or the panels removed. 23. Do not operate the dryer with missing or broken parts. 24. Do not bypass safety devices. 25. Keep area around the exhaust opening and adjacent surrounding areas free from accumulation of lint, dust, and dirt. 26. Interior of dryer and exhaust duct should be cleaned periodically by qualified service personnel. 27. The dryer will not operate with loading door open. DO NOT bypass the door safety switch by permitting the dryer to operate with door open. The dryer will stop tumbling when the door is opened. Do not use the dryer if it does not stop tumbling when door is opened or starts tumbling without pressing or turning the START mechanism. Stop using the dryer and contact a qualified service technician. 28. Remove laundry immediately after the dryer stops. 29. ALWAYS follow the fabric care instructions supplied by the garment manufacturer. ■ Electrical service information Electrical Dryers 240 VAC, 60 Hz, 30 Amps, 3-wire or 4-wire installations Gas Dryers 120 VAC, 60 Hz, 15 Amps, 3-wire installations WARNING To reduce the risk of fire, electric shock, serious injury or death, all wiring and grounding must conform with the latest edition of the National Electric Code, or the Canadian Electrical Code, and such local regulations as might apply. It is the customers responsibility to have the wiring and fuses checked by a qualified electrician to make sure your home has adequate electrical power to operate the dryer. WARNING To avoid risk of personal injury or death due to electrical shock: - Observe all local codes and ordinances. - Disconnect the electrical power to the unit before servicing. - Ground the appliance properly. - Check with a qualified electrician if you are not sure this appliance is properly grounded. - DO NOT ground to a gas line. - DO NOT ground to a cold water pipe if pipe is interrupted by plastic, nonmetallic gaskets, or other insulating (nonconducting) materials. - DO NOT modify the plug on the power cord. If plug does not fit electrical outlet, have proper outlet installed by qualified electrician.

  • Page 6: Gas Dryer Power Supply

    ■ Gas dryer power supply This equipment MUST be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electrical current. This unit is equipped with a cord having a grounding wire with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded. Consult a qualified electrician or servicer if grounding instructions are not completely understood, or if doubt exists as to whether the equipment is properly grounded. Do not use an extension cord. If the product power cord is too short, have a qualified electrician install a three slot receptacle. This unit should be plugged into a separate 60 hertz circuit with the electrical rating as shown on the serial plate. ■ Proper grounding and polarization for 120 volts wall outlets For the safety of our customers and the service technician ALL gas Ground dryers have a three-prong power cord and MUST be connected to a Neutral properly polarized and grounded wall outlet. This information was written for those who do not understand grounding and polarization of a wall Neutral side outlet. A 120 VAC wall outlet must always be wired as shown right. Polarization - This means that the larger slot must be neutral and the 115±15 small slot must be hot (live). V.A.C. V.A.C. Mispolarized - The outlet is miswired so that the larger slot is hot (live) and the smaller slot is neutral. 115±12 Grounded - This means the round hole connection is connected to V.A.C.
