• Always follow the fabric care instructions supplied by the garment manufacturer.

• Remove laundry immediately after the tumbler stops.

• Do not reach into the tumbler if the cylinder is revolving.

• Do not allow children to play on or in the tumbler. Close supervision of children is necessary when the tumbler is used near children.

• Before the tumbler is removed from service or discarded, remove the door to the drying compartment.

• Do not install or store the tumbler where it will be exposed to water and/or weather.

• Always disconnect the electrical power to the tumbler before servicing.

• To reduce the risk of serious injury, install lockable door(s) to prevent public access to the rear of the tumbler.

To avoid creating any flammable vapors which may explode, ignite, or cause corrosive damage, DO NOT dry the following materials in your SPEED QUEEN SC50EG:

• Articles that have been cleaned in, soaked in, washed in, or spotted with gasoline, dry cleaning solvents, or other flammable/explosive substances.

• Plastics or articles containing foam rubber or similarly textured rubber-like materials.

• Articles that have traces of flammable substances like cooking oil, machine oil, flammable chemicals, or thinner. Do not put articles soiled with vegetable or cooking oil in the dryer, as these oils may not be removed during washing. Due to the remaining oil, the fabric may catch on fire by itself.

• Articles containing wax or cleaning chemicals.

• Fiberglass curtains or draperies (unless the label says it can be done).

• Use only for drying water-washed fabrics.

The model and serial numbers for your SPEED QUEEN SC50EG will be found on the nameplate. The nameplate is located on the rear of the tumbler or underneath the door hinge.

REVERSING MOTOR SIZES

FLOOR: The SPEED QUEEN SC50EG may be installed on any level floor capable of supporting 100 pounds per square foot (488 kg/m²). Floor covering materials such as carpeting or tile should be removed.

LAYOUT: Whenever possible, the tumbler should be installed along an outside wall where duct length can be kept to a minimum, and make-up air can be easily accessed. Construction must not block airflow at the top rear of the tumbler, as this would prevent an adequate air supply.

VENTING: For maximum efficiency and minimum lint accumulation, tumbler air must be exhausted to the outdoors by the shortest possible route. Proper sized exhaust ducts are essential. Exhaust ducts shall be constructed of sheet metal or other noncombustible material.

MAKE-UP AIR: The tumbler is a forced air exhausted unit and requires provisions for make-up air to replace the air it exhausts. The recommended make-up air opening is 144 square inches (928 sq. cm). Protective louvers can reduce air movement by approximately 40%, so the opening must compensate for the area taken up by louvers.

REQUIREMENTS (Reversing Models)

ELECTRIC DRYING TUMBLERS (NOTE: DO NOT use aluminum wire.)

WARNING: All electrical connections should be made by a qualified electrician. To reduce the risk of electrical shock, de-energize the electrical circuit being connected to the tumbler before making any electrical connections. Never attempt to connect a live circuit.

1. Install a circuit breaker as close to the tumbler as possible. If more than one tumbler is being installed, a circuit breaker should be provided for each tumbler.

2. a. Connect conduit-encased leads to the circuit breaker.

2. b. Turn “off” the disconnect switch on the tumbler and open the junction box.

2. c. Insert conduit-encased leads through one of the knockout holes in the junction box.

2. d. Connect wire leads to the disconnect switch.

• 1 Phase Units: Connect one lead to the top left connection point. Connect the other lead to the top right connection point.

• 3 Phase Units: Connect one lead to each connection point.

2. e. Connect a ground wire to the PE Busbar in the junction box.

3. Check electrical service phase sequence (three-phase only) as follows:

a. Energize electrical service and momentarily start the tumbler. Check the direction of the cylinder rotation. If the cylinder rotates clockwise (viewed from the front), the phase sequence is correct. If it rotates counterclockwise, proceed with step “b”.

b. Disconnect power and reverse any two leads at the connections.

4. Close the junction box cover and turn “on” the disconnect switch.

Positioning:

The tumbler may be removed from its shipping skid before moving to the installation location. Remove the tumbler from the skid by unscrewing the four shipping capscrews (one at each corner). The lint panel door will have to be removed to access two front capscrews. NOTE: Do not throw these four capscrews away – they are the leveling legs.

Screw the four leveling legs back into the level adjusting fittings from the top. Slide the tumbler to its permanent location. Keep the tumbler as close to the floor as possible. All four legs must rest firmly on the floor so the weight of the tumbler is evenly distributed. The tumbler must not rock.

Leveling:

The SPEED QUEEN SC50EG should be leveled within 1/8 inch (3.2 mm) from front to rear, and 1/8 inch (3.2 mm) from side to side. To check the front-to-rear level, rotate the clothes cylinder until one rib is at the bottom, then place a level on that bottom rib. The side-to-side level should be checked by placing a level on the front and rear of the top panel.

1. Remove or open all panels and inspect accessible bolts, nuts, screws, terminals, and fittings for security.

2. Check belt tension and adjust if necessary (refer to the Adjustment Section).

3. Energize the electrical circuit to the tumbler circuit breaker and turn on the tumbler disconnect switch.

4. Load the tumbler with clothes or clean rags.

5. Press and hold in the Push-to-Start Button for approximately three (3) seconds. Release the button and open the cylinder door. The cylinder should stop rotating within seven (7) seconds after the door is opened 3 inches (7.5 cm) plus or minus 1/4 inch (0.635 cm). If the cylinder does not stop, adjust the cylinder door interlock.

6. Start the tumbler.

7. Check the air flow switch operation by opening the lint panel. The heating system should shut off when the lint panel is opened approximately 1-1/2 inches (3.81 cm). Adjust if necessary.

8. Turn off the tumbler.

9. Check the air flow switch operation again by opening the lint panel. The heating system should shut off when the lint panel is opened approximately 6 inches (15.24 cm) with a full load.

Your SPEED QUEEN SC50EG comes equipped with an Electronic Control, which gives the owner a variety of programming options. To learn how to use the Electronic Control, consult the supplemental manual that was provided with your machine.

NOTICE: The control panel must be in place and the access door closed before attempting to adjust the air flow switch.

IMPORTANT: The air flow switch disc must remain closed during operation. If it opens and closes during the drying cycle, this indicates insufficient air flow through the tumbler.

WARNING: To reduce the risk of fire, air flow switch operation may be affected by a clogged lint screen, lack of make-up air, or obstructions in the ductwork. These conditions must be checked and necessary corrections made before adjusting the switch.

The counterweight should be adjusted so air flow will force the disc away from the cabinet when the lint panel is opened 6 inches (15.24 cm) with a full load. To adjust:

1. Load the tumbler.

2. Start the tumbler. Open the lint panel 6 inches (15.24 cm). The airflow disc should move away from the cabinet, opening the switch contacts and shutting off the heat system. This indicates proper operation.

3. If the switch is not opening as described, it should be adjusted to be MORE sensitive. Depress the spring clip and move the counterweight toward the disc. Retest by opening the lint panel and continue moving the counterweight toward the disc until it operates correctly.

4. If the switch opens BEFORE the lint panel is opened the proper distance, it should be adjusted to be LESS sensitive. Depress the spring clip and move the counterweight away from the disc. Retest and continue moving the counterweight away from the disc until it operates correctly.

The loading door switch turns off the tumbler any time the loading door is opened. To adjust it, follow these steps:

1. Start the tumbler following the operating instructions.

2. Slowly open the loading door. The cylinder and heating system should stop when the door is open 3 inches (7.5 cm) plus or minus 1/4 inch (0.635 cm).

3. Slowly close the loading door. The loading door switch should close with an audible “click” when the loading door is closed 3 inches (7.5 cm) plus or minus 1/4 inch (0.635 cm).

4. If the loading door switch does not close at the correct point:

a. Close the loading door completely.

b. Loosen the lower screw on the switch coupler and rotate the switch coupler COUNTERCLOCKWISE until it stops.

c. Tighten the lower screw on the switch coupler.

d. Return to step 1 to verify the loading door switch operation.

The door strike must be adjusted to have sufficient tension to hold the loading door closed against the force of the load tumbling against it. Proper adjustment is when 8 to 15 pounds (35.6 N – 66.7 N) of pull is required to open the door.

To adjust, open the door, loosen the jamnut on the door strike, and turn the door strike screw in or out as required. Retighten the jamnut once the adjustment is correct.

WARNING: To reduce the risk of serious injury or death, disconnect power to the tumbler before performing this operation.

Proper tension is when the belt can be depressed approximately 1/2 inch (1.27 cm) by applying light thumb pressure at a point midway between the sheave and motor pulley. The upper belt (Poly V-belt) is self-adjusting and requires no adjustment.

1. Remove the guard from the rear of the tumbler.

2. To adjust the belt tension, loosen the adjusting bolt holding the idler housing assembly to the housing support.

3. To tighten the V-belt:

a. Loosen the lower nut on the adjusting bolt.

b. Turn the bolt up until the belt has proper tension.

c. Tighten the upper and lower nut or adjusting bolt.

4. To loosen the V-belt:

a. Loosen the top nut on the adjusting bolt.

b. Turn the bolt down until the belt has proper tension.

c. Tighten the upper and lower nut or adjusting bolt.

5. Replace the guard on the rear of the tumbler.

WARNING: To reduce the risk of serious injury or death, the guard MUST be installed on the rear of the tumbler after the belt adjustment is made.

1. Make certain the drying cycle has ended.

2. Open the loading door.

3. Unlock and remove the lint panel.

4. Remove accumulated lint in the lint compartment. Lint left in the compartment will be drawn back onto the lint screen and restrict air circulation.

5. Clean lint from the lint screen. If the lint screen is torn, replace it immediately. A torn lint screen allows lint to flow into the ductwork system, restricting air circulation.

6. Ensure the lint screen covers the entire opening in the lint screen hood. Gaps allow lint to flow into the ductwork.

7. Wipe any accumulated lint off the thermostat sensing probe. Lint buildup on the sensing probe will cause overheating of the tumbler.

8. Replace and securely lock the lint panel.
