IMPORTANT: Remove the shipping tape from the two back draft dampers located in the exhaust thimble.

For your electric SPEED QUEEN SCB75CE tumbler, you will need to obtain one circuit breaker locally.

FLOOR

The drying tumbler 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.

MAKE-UP AIR

A tumbler is a forced air exhaust and requires provisions for make-up air to replace the air exhausted by the tumbler.

Proper sized exhaust ducts are essential for proper operation. All elbows should be sweep type. Exhaust ducts must be assembled so interior surfaces are smooth to reduce lint accumulation. Do not use sheet metal screws to join vent sections.

Exhaust ducts shall be constructed of sheet metal or other noncombustible material, equivalent in strength and corrosion resistance to galvanized sheet steel not less than 0.0195 inches (0.495 mm) thick.

Where an exhaust duct pierces a combustible wall or ceiling, an opening having a diameter of 4 inches (10.2 cm) larger than the duct’s diameter shall be provided, with the duct centered in the opening. The space around the duct must be sealed with non-combustible material.

Individual Venting

It is preferred to exhaust tumblers individually to the outdoors. The cross-sectional area of the installed venting must not be less than the cross-sectional area of the tumbler’s exhaust thimble. The maximum allowable length of venting is 14 feet (4.3 m) plus two 90° elbows or equivalent. With the tumbler in operation, airflow at any point in the duct must be at least 1200 feet (366 m) per minute to ensure lint remains airborne.

Equivalent Length (feet) (m) = 1.17 x Duct Diameter (inches) (cm)

The recommended make-up air opening for the 75-pound SPEED QUEEN SCB75CE is 195 square inches (1258 sq. cm). At a minimum, tumblers must have at least 1 in² (2.54 cm²) of opening for every 1000 BTU/hr (252 Kcal/hr) of input rating for proper combustion.

Protective louvers in an opening to the outdoors can reduce air movement by approximately 40%. The opening must compensate for the area taken up by louvers.

If it is necessary to duct make-up air to the tumbler, increase the area of the ductwork by 25% to compensate for any restriction in air movement.

Yes. Please adhere to the following warning:

WARNING: To reduce the risk of fire and accumulation of combustible gases, DO NOT exhaust tumbler air into a window well, gas vent, chimney or enclosed, unventilated area such as an attic wall, ceiling, crawl space under a building, or concealed space of a building.

NOTE: Do not install wire mesh or screen in the exhaust opening as lint will build up and prevent proper discharge of air from tumblers. The inside of the duct shall be smooth. Do not use sheet metal screws to join sections.

The following tables outline the electrical requirements for 75 Pound (34 kg) tumblers like the SPEED QUEEN SCB75CE.

REQUIREMENTS

ELECTRIC DRYING TUMBLERS

NOTE: DO NOT use aluminum wire.

Your SPEED QUEEN SCB75CE tumbler must be grounded. In the event of a malfunction or breakdown, grounding will reduce the risk of electric shock by providing a path of least resistance for electric current. The tumbler must be connected to a grounded metal, permanent wiring system; or an equipment grounding conductor must be run with the circuit conductors and connected to the PE Busbar.

WARNING: To reduce the risk of fire and electric shock, check with a qualified serviceman for proper grounding procedures. Improper connection of the equipment grounding conductor can result in a risk of electric shock.

WARNING: To reduce the risk of fire and electric shock, if electrical supply is coming from a three phase service, DO NOT connect a “Stinger Leg” to a single phase machine.

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.

Use the following steps to connect electrical service to the tumbler:

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

2. Making connections:

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

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

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

d. Connect wire leads to the disconnect switch.

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 the 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 and reverse any two leads at the connections.

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

Positioning

The tumbler can be removed from its shipping skid before or after moving to its installation location. To remove it from the skid, unscrew the four shipping capscrews (one at each corner). The lint panel door will need 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 is evenly distributed and the tumbler does not rock.

Leveling

The tumbler 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. Check the front-to-rear level by rotating the 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, adjust if necessary (refer to 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″ (7.5 cm) plus or minus 1/4″ (0.635 cm). If the cylinder does not stop rotating, adjust the cylinder door interlock.

6. 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″ (3.81 cm). Adjust if necessary.

7. Turn off the tumbler.

8. Check air flow switch operation again by opening the lint panel. Heating systems should shut off when the lint panel is opened approximately 6″ (15.24 cm) with a full load.

Coin Operated Tumbler

1. Set temperature selector to HIGH.

2. Insert the required amount of coins.

3. Press and hold in the Push-to-Start Button for approximately three (3) seconds. The motor will start and the heat system will turn on.

4. Near the end of the cycle a preset 2 1/2 minute cool down cycle will start.

5. When metered time expires, the motor will stop, indicating the drying cycle is finished.

Electronic Control Tumbler

Your SPEED QUEEN SCB75CE comes equipped with Electronic Control, which gives the owner a variety of programming options. To learn how to use the Electronic Control, consult the supplemental manual.

The air flow switch is factory-set for proper operation. If an adjustment is needed, follow these steps:

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 ducts. These conditions must be checked and corrected before adjusting the air flow switch. Always adjust air flow at installation.

The counterweight should be adjusted so airflow will force the disc away from the cabinet when the lint panel is opened 6 inches (15.24 cm) with a full load. Adjust as follows:

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 does not open as described, it needs to be MORE sensitive. Depress the spring clip and move the counterweight toward the disc. Retest 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 is 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 anytime the loading door is opened. To adjust it, follow these steps:

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

4. If the switch does not close at the correct position:

a. Close the loading door completely.

b. Loosen the lower screw on the switch coupler and rotate the 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 tumbling load. 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. Once adjusted, retighten the jamnut.

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.

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

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

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.

6. The upper belt (Poly V-belt) requires no adjustment as it is self-adjusting.

WARNING: To reduce the risk of serious injury or death, the guard MUST be installed on the rear of the tumbler after 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 between the lint screen and hood 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.
