To reduce the risk of fire, electrical shock, serious injury or death to persons when using your SPEED QUEEN JCB75CG dryer, follow these basic precautions:

1. Do not allow children to play on or in the tumbler. Close supervision of children is necessary when the tumbler is used near children. This is a safety rule for all appliances.

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

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

4. Failure to install, maintain, and/or operate this machine according to the manufacturer’s instructions may result in conditions which can produce serious injury, death and/or property damage.

5. Run tumbler with a load before putting tumbler into service.

6. Always disconnect the electrical power to the tumbler before servicing. Disconnect power by shutting off the appropriate circuit breaker or fuse and by turning off the disconnect switch located on the rear of the tumbler.

7. All manually operated models are factory-equipped with an emergency stop button located on the front panel. If the emergency stop function is desired on coin-operated models, an external emergency stop switch may be installed as specified on the machine wiring diagram. Activation of the emergency stop switch stops all machine control circuit functions, but does not remove all electrical power from the machine.

To reduce the risk of fire, electrical shock, serious injury or death to persons when using the SPEED QUEEN JCB75CG, follow these basic precautions:

• Read all instructions before using tumbler.

• DO NOT tamper with controls.

• DO NOT 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 tumbler if cylinder is revolving.

If the tumbler does not perform according to these instructions, immediately disconnect electrical service, shut off gas supply and contact an authorized service representative. Service and repairs are to be performed by authorized service representatives only.

To avoid creating any flammable vapors which may explode, ignite or cause corrosive damage, DO NOT dry the following materials in the SPEED QUEEN JCB75CG:

• 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 rubberlike 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.

The following warning labels will be found on the SPEED QUEEN JCB75CG drying tumbler:

• **Fire Hazard Symbol:** A clothes dryer produces combustible lint. TUMBLER MUST BE EXHAUSTED OUTDOORS.

REVERSING MOTOR SIZES

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

Remove the crate and protective cover as soon as possible and check the items listed on the packing list.

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

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 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 manufacturer’s recommended make-up air opening is 195 square inches (1258 sq. cm). At a minimum, the tumbler 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 can reduce air movement by approximately 40%, so the opening must compensate for the area taken up by louvers.

Properly sized exhaust ducts are essential for proper operation. All elbows should be sweep type. Exhaust ducts must be constructed of sheet metal or other noncombustible material, with smooth interior surfaces to reduce lint accumulation. Do not use sheet metal screws to join vent sections.

Individual Venting: It is preferred to exhaust the tumbler individually to the outdoors. The maximum allowable length of venting is 14 feet (4.3 m) with two 90° elbows or equivalent. At no point may the cross area of installed venting be less than the cross area of the exhaust thimble of the tumbler.

Collector Venting: A main collector duct may be used if sized properly. The collector duct must be tapered, and individual tumbler ducts must enter the collector duct at a 45° angle in the direction of air flow. Never connect a tumbler duct at a 90° angle or connect two ducts directly across from each other.

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 table below shows how to determine equivalent venting length for elbows:

The SPEED QUEEN JCB75CG is a gas model. The electrical requirements are as follows:

NOTE: DO NOT use aluminum wire.

The SPEED QUEEN JCB75CG drying 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 drying 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. Check with a qualified serviceman for proper grounding procedures, as 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.

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. 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 (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 can be removed from its shipping skid before or after moving it to its installation location. To remove it from the skid, unscrew 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 is evenly distributed and the tumbler does not rock.

Leveling:

The SPEED QUEEN JCB75CG 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 (length, tees, etc.). Specific pipe size information should be obtained from a gas supplier. It is important that equal gas pressure is maintained at all tumbler gas connections. This can be achieved by installing a one-inch pipe gas loop.

WARNING: If the tumbler is connected to Liquefied Petroleum (L.P.) gas, a vent to the outdoors must be provided in the room where the tumbler is installed.

Gas Connections:

Before connecting, ensure the gas service is the same as specified on the nameplate.

• NATURAL GAS service must be supplied at 6½ ± 1½ inch water column pressure (1.62 ± .37 kPa).

• L.P. GAS service must be supplied at 11 ± .3 inch water column pressure (2.74 ± .07 kPa).

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

Purge air and sediment from the gas service line before connecting it loosely to the tumbler. Purge remaining air until the odor of gas is detected, then tighten the connection. Use pipe compound resistant to 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.

The following table shows the required gas pipe size for 1,000 BTU Natural Gas (.64 specific gravity) at 6½ ± 1½ inch water column pressure, based on a 0.3″ water column pressure drop for the given length.

IMPORTANT: DO NOT block airflow at the top rear of the tumbler with laundry, etc. Doing so would prevent adequate air supply to the tumbler’s heat chamber.

WARNING: To reduce the risk of serious injury, install lockable doors to prevent public access to the rear of the tumblers.

A typical tumbler enclosure can touch the tumbler’s top and side panels. Follow these clearance requirements:

• **Top Clearance:** Clearance of the tumbler cabinet from combustible construction must be a MINIMUM of 12 inches (30.5 cm) at the top.

• **Front Side Clearance:** 0″ clearance is permitted for the first 4″ (10.16 cm) of the side panel from the front. After the first 4″, a maximum of 4″ (10.16 cm) clearance to an adjacent structure is allowed.

• **Side Clearance (from non-door side):** 0″ clearance is permitted.

• **Rear Clearance:** A minimum of 24″ (61 cm) and a recommended 36″ (91.4 cm) clearance is needed for maintenance purposes.

Be aware that there may be local codes and ordinances which must also be complied with.

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 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 the gas shut-off valve is in the “on” position, and return to step three.

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 (the gas valve handle should be at a right angle to the gas line).

To figure time increments, use the formula: Timer Motor Speed (60) divided by the number of pins on the cam = Cycle Length (minutes). Cams are available with 1 to 12 pins.

Example: 60 ÷ 5 (Pin cam) = 12 minute cycle.

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 the pressure is directed upward and that the “V” notch clears the ratchet tooth.

INSTALLATION OF NEW TIMING CAM:

1. Insert the drive 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 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; 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. Turn on the gas supply at the manual gas shut-off valve in the gas supply line (gas models only). 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 the cylinder does not stop rotating, adjust the cylinder door interlock.

6. Load the tumbler with clothes or clean rags.

7. Start the tumbler and check the burner flame; adjust 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). Adjust if necessary.

9. Turn off the tumbler.

10. Check airflow switch operation 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.

Manual Dual Timer Tumbler:

1. Set the temperature selector to HIGH and set the drying and cool-down selectors to their maximum settings.

2. Press and hold the Push-to-Start Button for approximately three (3) seconds. The motor will start, the heat system will turn on, the drying indicator will light, and the drying selector will rotate counterclockwise.

3. When the drying selector reaches zero (0), the heat system will shut off, the drying indicator will turn off, the cooling indicator will light, and the cooling selector will rotate counterclockwise.

4. When the cooling selector reaches zero (0), the motor will stop, and the cooling indicator will turn off, indicating the drying cycle is finished.

Coin Operated Tumbler:

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.

Electronic Control Tumbler:

The tumbler 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.

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

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 the air shutter is adjusted for a proper flame, tighten the air shutter adjusting screw securely. The control panel may have to be removed temporarily to loosen the air shutter screws to turn the shutter.

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

WARNING: To reduce the risk of fire, airflow 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 airflow 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. 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, 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 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 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 the loading door switch, 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″ (7.5 cm) plus or minus 1/4″ (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″ (7.5 cm) plus or minus 1/4″ (0.635 cm).

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

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 inside. Proper adjustment is achieved when a pull of 8 to 15 pounds (35.6 N – 66.7 N) 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.
