ELECTRICAL REQUIREMENTS Electrical Connection To properly install your dryer, you must determine the type of electrical connection you will be using and follow the instructions provided for it here. • This dryer is manufactured ready to install with a 3-wire electrical supply connection. The green cabinet-grounding conductor is permanently connected to the neutral conductor (white wire) within the dryer.
If using a power supply cord: Use a UL listed power supply cord kit marked for use with clothes dryers. The kit should contain: • A UL listed 30 amp power supply cord, rated 120/240-volt minimum. The cord should be type SRD or SRDT and be at least 4 ft (1.22m) long. The wires that connect to the dryer must end in ring terminals or spade terminals with upturned ends. • A UL listed strain relief.
ELECTRICAL CONNECTION Power Supply Cord Direct Wire WARNING WARNING Fire Hazard Use a new UL listed 30 amp power supply cord. Use a UL listed strain relief. Disconnect power before making electrical connections. Connect neutral wire (white or center wire) to center terminal (silver). Ground wire (green or bare wire) must be connected to green ground connector. Connect remaining 2 supply wires to remaining 2 terminals (gold). Securely tighten all electrical connections.
6. Replace strain relief (with power cord inserted) back into the terminal block cover. Do not tighten strain relief nut. 4-Wire Connection: Power Supply Cord B A D C A. 4-wire receptacle (NEMA type 14-30R) B. 4-prong plug C. Ground prong D. Neutral prong E.

4-Wire Connection: Direct Wire Direct wire cable must have 5 ft (1.52 m) of extra length so dryer can be moved if needed. Strip 5″ (12.7 cm) of outer covering from end of cable, leaving bare ground wire at 5″ (12.7 cm). Cut 1-1/2″ (3.8 cm) from three remaining wires. Strip insulation back 1″ (2.5 cm). Shape ends of wires into a hook shape. 2. 3. 4.

B 3-Wire Connection: Direct Wire Use where local codes permit connecting cabinet-ground conductor to neutral wire. Direct wire cable must have 5 ft (1.52 m) of extra length so dryer can be moved if needed. Strip 3-1/2″ (8.9 cm) of outer covering from end of cable. Strip insulation back 1″ (2.5 cm). If using 3-wire cable with ground wire, cut bare wire even with outer covering.
3. Place the hooked ends of the other power supply cable wires under the outer terminal block screws (hooks facing right). Squeeze hooked ends together. Tighten screws. 4. 5. 2-9 Replace the terminal block cover on the back of the dryer. Tighten strain relief nut.
VENTING REQUIREMENTS IMPORTANT: Observe all governing codes and ordinances. WARNING Improper venting can cause moisture and lint to collect indoors, which may result in: • Moisture damage to woodwork, furniture, paint, wallpaper, carpets, etc. • Housecleaning problems and health problems. Fire Hazard Use a heavy metal vent. Do not use a plastic vent. Do not use a metal foil vent. Failure to follow these instructions can result in death or fire.
PLAN VENT SYSTEM Typical Exhaust Installations Typical installations vent the dryer from the rear of the dryer. A Special Provisions For Mobile Home Installations The exhaust vent must be securely fastened to a noncombustible portion of the mobile home structure and must not terminate beneath the mobile home. Terminate the exhaust vent outside. B C A. Exhaust hood B. Flexible metal vent or rigid metal vent C. Elbow Alternate Installation For Close Clearances Venting systems come in many varieties.
2. Determine vent length. The maximum length of the exhaust system depends upon: • The type of vent (rigid metal or flexible metal). • The number of elbows used. • Type of hood. Vent Length Chart Number of 90° Type of vent turns or elbows Recommended hood styles are shown here. B Box or louvered Angled hoods hoods 0 Rigid metal 90 ft (27.4 m) 80 ft (24.4 m) Flexible metal 64 ft (19.5 m) 58 ft (17.7 m) 1 Rigid metal 80 ft (24.4 m) 70 ft (21.3 m) Flexible metal 58 ft (17.7 m) 52 ft (15.
CONNECT VENT 1. 2. 4. Using the coupling supplied with the dryer, connect the exhaust vent to the coupling and secure with a 4″ (10.2 cm) vent clamp. See Illustration below. If connecting to existing vent, make sure the vent is clean. Turn the coupling (together with the exhaust vent) counterclockwise in the air discharge outlet on the back of the dryer. The dryer exhaust vent must fit over the coupling and inside the exhaust hood. A B CD E A. Coupling B. Vent clamp C. Vent coupler D. Vent clamp E.

PRODUCT OPERATION THEORY OF OPERATION HEATER OPERATION In the Low temperature setting, a switch opens the circuit to R2, and it is removed, and drying takes place with the R1 element only. This dryer uses a dual element heater. Depending on the selected temperature, either one or both of the elements will be in the circuit during the drying mode. In the Normal temperature setting, both elements are in the circuit. One element (R1) is controlled by the operating thermostat.
AIRFLOW DRUM MOTION Primary air is introduced into the dryer through the slots in the air intake cover. The main drive motor is reversible. It starts in one direction, stops, then reverses direction. It continues this throughout the drying cycle. MOISTURE SENSOR A moisture sensor circuit is created through the drum baffles and the brushes on the outside of the drum.
DRYER USE STARTING THE DRYER 4. Press the TEMPERATURE button to select the recommended temperature setting for the type of load being dried. 5. Turn the cycle knob to the recommended setting for the type of load being dried. 6. After a short beep sounds, press the START button. WARNING STOPPING & RESTARTING Explosion Hazard Keep flammable materials and vapors, such as gasoline, away from dryer. Do not dry anything that has ever had anything flammable on it (even after washing).
• Avoid drying heavy work clothes with lighter fabrics. This could cause overdrying of lighter fabrics, leading to increased shrinkage or wrinkling. LOADING Load clothes loosely into the dryer. Do not pack the dryer. Allow space for clothes to tumble freely. The following chart shows the maximum load you can place in your compact dryer. Expect longer drying times. Cycle And TemperatureTips • Dry most loads using an automatic cycle. • Line dry bonded or laminated fabrics.
See following table for recommended cycles and temperature settings. Fabric Type Cycle End of Cycle Signal The dryer sounds a signal to let you know when the cycle is finished. The signal is not adjustable and cannot be turned off. The signal is helpful when you are drying permanent press, synthetics, and other items that should be taken out as soon as the dryer stops.

COMPONENT TESTING Before testing any of the components, perform the following checks: • Control failure can be the result of corrosion on connectors. Therefore, disconnecting and reconnecting wires will be necessary throughout test procedures. • All tests/checks should be made with a VOM or DVM having a sensitivity of 20,000 ohmsper-volt DC, or greater. • Check all connections before replacing components, looking for broken or loose wires, failed terminals, or wires not pressed into connectors far enough.
