Upon delivery, visually inspect the crate carton and parts for any visible shipping damage. If there is 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. Remove the crate and protective cover and check the items against the packing list. File a written claim with the carrier immediately if articles are damaged or missing. IMPORTANT: Remove the shipping tape from the two back draft dampers located in the exhaust thimble.

The following materials, which must 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 JCB50EG 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: Construction must not block airflow at the top rear of the tumbler. Doing so would prevent an adequate air supply to the tumbler’s combustion chamber.

Properly sized exhaust ducts are essential for the operation of your SPEED QUEEN JCB50EG. For maximum efficiency and minimum lint accumulation, tumbler air must be exhausted to the outdoors by the shortest possible route.

• 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 4 inches (10.2 cm) larger in diameter 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 each tumbler individually. At no point may the cross area of the installed venting be less than the cross area of the tumbler’s exhaust thimble.

• **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 to the collector duct.

• 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 maximum allowable length of venting is 14 feet (4.3 m) and two 90° elbows or equivalent. Use the following table to determine the equivalent length of straight duct for 90° elbows.

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

The SPEED QUEEN JCB50EG is a forced air exhausted tumbler 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).

• At a minimum, the tumbler must have at least 1 sq. inch (2.54 cm²) of opening for every 1000 BTU/hr of input rating for proper combustion.

• Protective louvers in the opening can reduce air movement by approximately 40%, so the opening must be sized to compensate for the area taken up by louvers.

• 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.

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.

The SPEED QUEEN JCB50EG is a reversing model. It must be grounded. Improper connection of the equipment grounding conductor can result in a risk of electric shock. DO NOT connect a “Stinger Leg” from a three-phase service to a single-phase machine.

Terminal Block Connection for Reversing Gas & Steam Models (230/50/1):

GAS AND HIGH PRESSURE STEAM DRYING TUMBLERS

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. Follow these sub-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 electrical service and momentarily start the tumbler. Check the direction of cylinder rotation. If the cylinder rotates clockwise (viewed from the front), the phase sequence is correct.

b. If the cylinder rotates counterclockwise, 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 to the installation location. To remove, 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 away these four capscrews; 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 JCB50EG 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 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.

The size of the gas service pipe depends on many variables like length and fittings; 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. This can be achieved by installing a one-inch pipe gas loop. Line pressure must be maintained at 6-1/2″ ± 1-1/2″ water column inches for Natural Gas, or 11 ± .3 water column inches for L.P. Gas, with all gas appliances running.

WARNING: To reduce the risk of fire or explosion, if the SPEED QUEEN JCB50EG 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.

The following table is for Natural Gas at 6½ ± 1½ inch water column pressure, based on a 0.3″ water column pressure drop.

Note: Table has been truncated for brevity. Refer to the full table in the manual for all values.

Before connecting, verify the gas service is the same as specified on the nameplate. Natural Gas requires 6½ ± 1½ inch water column pressure. L.P. Gas requires 11 ± .3 inch water column pressure. If service is not correct, DO NOT CONNECT; the burner orifice and gas valve must first be converted by authorized personnel.

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 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).

IMPORTANT: DO NOT block airflow at the top rear of the tumbler with laundry, etc. This would prevent an 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 tumblers.

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

• A 0-inch clearance is permitted for the first 4 inches (10.16 cm) along the front of the machine.

• A minimum of 24 inches (61 cm) is recommended at the rear for maintenance purposes, with 36 inches (91.4 cm) being ideal.

• The enclosure must include a provision for make-up air.

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 its operating instructions. The ignition control circuitry will verify the airflow switch is open, then start the cylinder motor. Air flowing will close the airflow switch. The tumbler will purge air for 18 seconds, then ignition will start with a three-second release of gas and sparking of the ignitor.

NOTE: 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, open the access door, press the red button on the ignition control, close and lock the access door, verify the gas shut-off valve is “on,” and return to step 3.

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

Removal of Existing Cam:

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

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

Installation of New 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 fully seat the 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.

To figure time increments, use this 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.

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.

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 (handle parallel with the line for “ON”).

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 not, 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 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.

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: Before adjusting, ensure all lint is removed from the lint compartment and screen. Adjustments vary based on location, vent system, and gas pressure.

1. Unlock and open the access door.

2. Start the tumbler and check the flame pattern. A correct flame is primarily blue with small yellow tips and bends to the right of the heater section. A yellow, lazy, and smokey flame indicates too little air.

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 is flowing through the tumbler. A flame that flares to the right and left 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 ducts. These conditions must be checked and corrected before adjusting the switch. Always adjust air flow at installation.

The air flow switch is factory-set but can be adjusted 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 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.

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

1. Start the tumbler.

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 coupler COUNTERCLOCKWISE until it stops.

c. Tighten the lower screw on the switch coupler.

d. Return to step 1 to verify correct operation.

The door strike must be adjusted to have sufficient tension to hold the loading door closed against the force of a tumbling load. Proper adjustment is achieved 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 when finished.

WARNING: To reduce the risk of serious injury or death, disconnect power to the tumbler before performing this operation. The guard MUST be reinstalled on the rear of the tumbler after belt adjustment is made.

Proper tension is when the belt can be depressed approximately 1/2 inch (1.27 cm) with light thumb pressure at a point midway between the sheave and motor pulley. The upper poly V-belt is self-adjusting.
