SPEED QUEEN SC50CG (01) PDF DOCUMENT

Failure to install, maintain, and/or operate the SPEED QUEEN SC50CG according to the manufacturer’s instructions may result in conditions which can produce serious injury, death, and/or property damage. It is important to understand that common sense, caution, and carefulness are factors that cannot be built into the tumbler and must be supplied by the person(s) installing, maintaining, or operating it.

General Operation:

• To reduce the risk of fire, electrical shock, serious injury or death, do not operate the tumbler if it does not perform according to these instructions. Immediately disconnect electrical service, shut off the gas supply, and contact an authorized service representative. Service and repairs are to be performed by authorized service representatives only.

• Read all instructions before using the tumbler.

• Do not tamper with controls or bypass any safety devices.

• 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 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.

• Run the tumbler with a load before putting it into service for the first time.

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

Flammable & Hazardous Materials:

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

• 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.

• Articles containing wax or cleaning chemicals.

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

• 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.

• Solvent gases and vapors from dry cleaning machines create acids when drawn through the heater of a drying tumbler. Be sure the make-up air for the SPEED QUEEN SC50CG is free of solvent gases and vapors. If dry cleaning machines are in the same area, the tumbler make-up air must come from a source free of these vapors.

Installation Safety:

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

• 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.

When requesting information or replacement parts for your SPEED QUEEN SC50CG tumbler, you must mention the model and serial numbers. The model and serial numbers can be found on the nameplate 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 the crate, carton, or cover are damaged or show signs of possible damage, have the carrier note the condition on the shipping papers before signing the shipping receipt. If damage is discovered later, advise the carrier of the condition as soon as it is discovered.

Remove the crate and protective cover as soon as possible and check the items listed on the packing list. Advise the carrier of any damaged or missing articles immediately. A written claim should be filed with the carrier if articles are damaged or missing.

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

Materials Required (Obtain Locally):

• One circuit breaker.

• For Gas Drying Tumblers: One gas shut-off valve for the gas service line to each tumbler.

Facilities Required:

• Floor: The SPEED QUEEN SC50CG 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, the tumbler air must be exhausted outdoors by the shortest possible route.

• Make-Up Air: A tumbler is a forced air exhaust system and requires provisions for make-up air to replace the air it exhausts.

Venting Requirements:

Properly sized exhaust ducts are essential for proper operation. All elbows should be the sweep type. 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.

• Individual Venting: It is preferred to exhaust tumblers individually to the outdoors. The maximum allowable length of venting is 14 feet (4.3 m) plus two 90° elbows or equivalent. If the duct length exceeds this, the diameter must be increased.

• Duct Sizing: The table below shows the equivalent length of straight duct for a 90° elbow.

• Collector Venting: A main collector duct may be used if sized properly. It must be tapered, and individual tumbler ducts must enter the collector duct at a 45° angle in the direction of airflow. Never connect a tumbler duct at a 90° angle to a collector duct.

• Make-Up Air Requirements:

The recommended make-up air opening for the SPEED QUEEN SC50CG is 144 square inches (928 sq. cm). At a minimum, tumblers must have at least 1 sq. in. (2.54 sq. cm) of opening for every 1000 BTU/hr of input rating for proper combustion. Protective louvers can reduce air movement by approximately 40%, so the opening size must compensate for the area taken up by louvers.

Electrical Requirements for 50 Pound (22 kg) Gas Models:

Grounding Instructions:

The SPEED QUEEN SC50CG 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.

Follow these 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 tumbler.

2. Perform the following wiring steps:

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

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

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

d. Connect the wire leads to the disconnect switch. For 1 Phase Units, connect one lead to the top left connection point and the other lead to the top right connection point. For 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 only, check the electrical service phase sequence:

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

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

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

Positioning the Tumbler:

The tumbler can be removed from its shipping skid before or after moving it to the 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 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 of the tumbler is evenly distributed and it does not rock.

Leveling the Tumbler:

The SPEED QUEEN SC50CG 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.

Gas Requirements:

The size of the gas service pipe depends on many variables (lengths, tees, etc.). Before connecting, make certain the gas service is the same as specified on the nameplate.

• Natural Gas: Must be supplied at 6 ½ ± 1 ½ 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). A vent to the outdoors must be provided in the room where the tumbler is installed.

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.

Gas Connection Procedure:

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

3. 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.

Pressure Testing Warnings:

• 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 a 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 (the gas valve handle should be parallel with the gas line).

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

NOTE: The ignition control circuitry will verify the airflow switch is open before starting the cylinder motor. Once the motor starts, air flowing through the tumbler will close the airflow switch. The tumbler will purge air for 18 seconds. Ignition will then start with a three-second release of gas from the gas valve and sparking of the ignitor. If ignition does not occur during the 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 a lockout, open the access door and press the red button on the ignition control. Close and lock the access door, verify the gas shut-off valve is in the “on” position, and return to step 3.

Shutting Down the System:

If the tumbler will not start, or for service, 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 (the gas valve handle should be at a right angle to the gas line).

The cycle length is determined by the number of pins on the cam. The formula is: Timer Motor Speed (60) divided by the number of pins on the cam = Cycle Length (in minutes).

Removal of Existing Timing Cam:

1. Rotate the cam by hand until the “V” notch lines up beneath a ratchet tooth.

2. Insert a narrow screwdriver under the nylon cam, close to the clock shaft. Lift gently off the shaft, ensuring pressure is directed upward and the “V” notch clears the ratchet tooth.

Installation of New Timing Cam:

1. Insert the drive fork into the timing cam with the wide prong in the wide hole of the cam.

2. Position the timing cam and drive fork over the timer shaft, aligning the timer flat with the drive fork and the “V” notch with one of the ratchet teeth.

3. Press the timing cam down firmly to seat it onto the motor shaft.

4. Remove all accumulated time by turning the cam counterclockwise until the switch shuts off. Apply moderate clockwise pressure to the fully seated timing cam and drive against the timing motor shaft. The meter must be advanced electrically for one full cycle before an accurate measure of time can be made.

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 of the gas shut-off valve should be parallel with the gas supply line when in the “ON” position.

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 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 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.

9. Turn off the tumbler.

10. Check the air flow switch operation 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 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 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 lint screen.

Air shutter adjustments will vary by location. Opening the shutter increases primary air, while closing it decreases primary air. Adjust as follows:

1. Unlock and open the access door.

2. Start the tumbler and check the flame pattern. A correct air and gas mixture is indicated if the flame pattern 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 smokey.

3. To adjust the air shutter, 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 is flowing through the tumbler. If the flame pattern flares to the right and left, it indicates no air is flowing 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 corrected before adjusting the air flow switch. Always adjust air flow at installation.

The counterweight should be adjusted so that 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. 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 is not opening as described in step 2, it needs 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 6 inches, it needs 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.

Loading Door Switch Adjustment:

The loading door switch turns off the tumbler anytime the door is opened. To adjust:

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″ (7.5 cm) plus or minus 1/4″ (0.635 cm).

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

4. If the 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 new adjustment.

Cylinder Door Strike Adjustment:

The door strike must have sufficient tension to hold the door closed against the force of a tumbling load. Proper adjustment is when 8 to 15 pounds (35.6 N – 66.7 N) of pull force 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 when finished.

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 Poly V-belt is self-adjusting and requires no adjustment.

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