The model and serial numbers for your SPEED QUEEN SCB30XG tumbler will be found on the nameplate. The nameplate is located on the rear of the tumbler or underneath the door hinge.

Upon delivery, visually inspect the crate, carton, and parts for any visible shipping damage. If there is damage or signs of possible damage, have the carrier note the condition on the shipping papers before signing the receipt, or advise the carrier as soon as it is discovered. A written claim should be filed with the carrier immediately if articles are damaged or missing.

Remove the crate and protective cover and check items against the packing list. IMPORTANT: Remove shipping tape from the two back draft dampers located in the exhaust thimble.

The following materials, which should be obtained locally, are required for installation:

• One circuit breaker.

• One gas shut-off valve for the gas service line to the tumbler.

FLOOR: The SPEED QUEEN SCB30XG 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 to the tumbler’s combustion chamber.

VENTING: For maximum efficiency and minimum lint accumulation, tumbler air must be exhausted to the outdoors by the shortest possible route.

MAKE-UP AIR: The room must have adequate make-up air to replace the air exhausted by the tumbler.

Properly 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.

• **Material:** Exhaust ducts must 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.

• **Clearance:** Where the exhaust duct pierces a combustible wall or ceiling, an opening with a diameter 4 inches (10.2 cm) larger than the duct must 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 the SPEED QUEEN SCB30XG individually to the outdoors. At no point may the cross area of the installed venting be less than the cross area of the tumbler’s exhaust thimble.

• **Maximum Length:** The maximum allowable length of venting is 14 feet (4.3 m) and two 90° elbows or equivalent. If the required length exceeds this, the duct diameter must be increased.

• **Airflow:** With the tumbler in operation, airflow at any point in the duct must be at least 1200 feet (366 m) per minute to ensure that lint remains airborne.

The SPEED QUEEN SCB30XG tumbler is a forced-air exhausted appliance and requires provisions for make-up air to replace the air it exhausts.

• **Recommended Opening:** The manufacturer’s recommended make-up air opening is 144 square inches (928 sq. cm) for each 30-pound tumbler.

• **Minimum Opening:** At a minimum, the tumbler must have at least 1 sq. inch (2.54 sq. cm) of opening for every 1000 BTU/hr of input rating for proper combustion.

• **Louvers:** Protective louvers in an opening to the outdoors can reduce air movement by approximately 40%. The opening must be sized larger to compensate for the area taken up by louvers.

• **Other Appliances:** Make-up air openings for a room containing the tumbler and/or other gas-fired appliances must be increased sufficiently to prevent downdrafts in any vents when all tumblers are in operation. Do not locate gravity-vented appliances between the tumbler(s) and make-up air openings.

WARNING: Solvent gases and vapors from dry cleaning machines create acids when drawn through the heater of a drying tumbler. These acids are corrosive to the drying tumbler as well as to the laundry load being dried. Be sure make-up air is free of solvent gases and vapors. If dry cleaning machines are in the same area as the tumbler, then the tumbler make-up air must come from a source free of solvent gases and vapors.

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 the tumbler.

The SPEED QUEEN SCB30XG 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 the 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 SPEED QUEEN SCB30XG tumbler:

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. Follow these steps:

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

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.

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

3. For three-phase units, check the electrical service phase sequence.

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

The SPEED QUEEN SCB30XG 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 the 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.

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 placing 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.

The size of the gas service pipe depends on many variables. Specific pipe size information should be obtained from your gas supplier. It is important that equal gas pressure be maintained at all tumbler gas connections, which can be achieved by installing a one-inch pipe gas loop.

WARNING: To reduce the risk of fire or explosion, if the SPEED QUEEN SCB30XG tumbler is to be connected to Liquefied Petroleum (L.P.) gas, a vent to the outdoors must be provided in the room where the tumbler is installed.

Before connecting gas piping to the SPEED QUEEN SCB30XG, make certain the gas service is the same as specified on the nameplate.

• **Natural Gas:** Must be supplied at 6 1/2 ± 1 1/2 inch water column pressure (1.62 ± .37 kPa).

• **L.P. Gas:** Must be supplied at 11 ± .3 inch water column pressure (2.74 ± .07 kPa).

If the gas service is not the same as specified, DO NOT CONNECT THE GAS LINE. The gas burner orifice and gas valve must be converted first by authorized personnel.

Connection Steps:

1. Purge air and sediment from the gas service line before connecting it loosely to the tumbler.

2. Purge the remaining air until the odor of gas is detected, then tighten the connection.

3. Use pipe compound resistant to the actions of L.P. gas on all pipe threads.

WARNING: Check all pipe connections, internal and external, for gas leaks using a soapy solution. To reduce the risk of explosion or fire, DO NOT USE AN OPEN FLAME TO CHECK FOR GAS LEAKS! Gas connections should be checked annually for leakage.

WARNING: The tumbler and its individual shut-off valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45 kPa). The tumbler must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressure equal to or less than 1/2 psig (3.45 kPa).

Lighting the System:

1. Turn the machine disconnect switch, located on the rear of the tumbler, to the “on” position.

2. Turn the gas shut-off valve, located on the rear of the tumbler, to the “on” position (gas valve handle should be parallel with the gas line).

3. Start the tumbler, following the operating instructions that accompanied it.

Shutting Down the System:

If the tumbler will not start, remove it from service by turning the machine disconnect switch to the “off” position and turning the gas shut-off valve to the “off” position (gas valve handle should be at a right angle to the gas line).

The ignition control circuitry on your SPEED QUEEN SCB30XG will verify the airflow switch is open before starting. Once the motor starts, the airflow switch closes, and the tumbler will purge air for 18 seconds. Ignition will then start with a three-second release of gas and sparking of the ignitor.

If ignition does not occur during this first three seconds, the ignition control will “lockout,” causing the gas valve to close and a red button on the ignition control to illuminate.

To reset the ignition system, open the access door and press the red button on the ignition control. Close and lock the access door, verify that the gas shut-off valve is in the “on” position, and attempt to start the tumbler again.

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. Turn on the gas supply at the manual gas shut-off valve in the gas supply line. The handle should be parallel with the gas supply line when in the “ON” position.

5. Press and hold 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 it doesn’t stop, adjust the cylinder door interlock.

6. Load the tumbler with clothes or clean rags.

7. Start the tumbler and check the burner flame, adjusting the gas inlet shutter if necessary.

8. Check the airflow 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).

9. Turn off the tumbler.

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

1. Set the temperature selector to HIGH.

2. Insert the required amount of coins.

3. Press and hold 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 the metered time expires, the motor will stop, indicating the drying cycle is finished.

NOTICE: Both air inlet shutters on the burner must be adjusted for proper combustion and maximum efficiency. Before adjusting, ensure all lint is removed from the lint compartment and screen.

1. Unlock and open the access door.

2. Start the tumbler and check the flame pattern. A correct mixture is indicated if the flame is primarily blue with small yellow tips and bends to the right of the heater section. Too little air is indicated if the flame is yellow, lazy, and smoky.

3. To adjust, loosen the air inlet shutter adjusting screw.

4. Open or close the air shutter as necessary to obtain the proper flame intensity.

5. After adjustment, tighten the air shutter adjusting screw securely.

6. If the shutter is correctly adjusted but the flame pattern is straight up, it indicates insufficient primary air. A flame pattern that flares to the right and left indicates no air is flowing through the tumbler.

WARNING: Air flow switch operation may be affected by a clogged lint screen, lack of make-up air, or obstructions in ducts. These conditions must be checked and corrected before adjusting the switch. Always adjust airflow 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. 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. This indicates proper adjustment.

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 it toward the disc until it operates correctly.

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