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

Advise the carrier of any damaged or missing articles as soon as possible. A written claim should be filed with the carrier immediately if articles are damaged or missing.

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

The following materials should be obtained locally:

For all Electric Drying Tumblers:

• One circuit breaker.

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.

Properly sized exhaust ducts are essential for proper operation. All elbows should be sweep type. Do not install elbows with a radius less than shown in the table below. Exhaust ducts must be assembled so interior surfaces are smooth to reduce the accumulation of lint. Do not use sheet metal screws to join vent sections. Improperly sized or assembled ductwork causes excess back pressure which results in slow drying, lint collecting in the duct, lint blowing back into the room, and increased fire hazard.

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

Where the exhaust duct pierces a combustible wall or ceiling, an opening having a diameter of 4 inches (10.2 cm) larger than the diameter of the exhaust duct shall be provided, with the duct centered in the opening. When ducts pass through walls, ceilings, floors, or partitions, the space around the duct shall be sealed with non-combustible material.

Individual Venting: For maximum efficiency and performance, it is preferred to exhaust tumbler(s) individually to the outdoors. 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: While it is preferable to exhaust tumblers individually to the outdoors, a main collector duct may be used if it is sized appropriately. Collector duct may be rectangular in cross-section, as long as area is not reduced. Provisions should be made for lint removal and cleaning of the collector duct. The collector duct must be tapered. 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. Never connect two tumbler exhaust ducts directly across from each other at the point of entry to the collector duct.

The maximum allowable length of venting is 14 feet (4.3 m) and two 90° elbows or equivalent. If the equivalent length of a duct required for an installation exceeds the maximum allowable equivalent length, the diameter of a round duct must be increased by 10% for each additional 20 feet (6.1 m). The cross-section area of a rectangular duct must be increased by 20% for each additional 20 feet (6.1 m). The table below shows how to determine equivalent venting.

Example: A 6-inch (15.2 cm) diameter duct’s equivalent length of 14 feet (4.3 m) of duct and two 90° elbows is:

Equivalent length = 14 feet (4.3 m) + (2) 90° elbows

= 14 feet (4.3 m) + 7 feet (2.1 m) + 7 feet (2.1 m)

= 28 feet (8.5 m)

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

The manufacturer’s recommended make-up air opening for each tumbler is 195 square inches (1258 sq. cm) for 75-pound tumblers. 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 the opening to the outdoors can reduce air movement by approximately 40%. The opening must compensate for the area taken up by louvers.

Make-up air openings for a room containing tumbler(s) and/or gas-fired hot water heater or other gravity-vented appliances must be increased sufficiently to prevent downdrafts in any vents when all tumblers are in operation. Do not locate gravity-vented appliances between tumbler(s) and make-up air openings. If it is necessary to duct make-up air to tumbler(s), increase the area of work by 25% to compensate for any restriction in air movement.

REQUIREMENTS

ELECTRIC DRYING TUMBLERS (Note: DO NOT use aluminum wire)

The SPEED QUEEN JC75CE 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.

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 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. This will make it possible to disconnect each tumbler for maintenance purposes.

2. 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. Check the electrical service phase sequence (three-phase only) as follows:

a. Energize 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 the cylinder 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 Drying Tumbler:

The tumbler may be removed from the skid before moving to the installation location or moved while still attached to the skid. Remove the tumbler from the skid by unscrewing four shipping capscrews (one at each corner) and removing the tumbler from the skid. The lint panel door will have to be removed in order to remove 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 and level. 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. The tumbler must not rock.

Leveling Drying Tumbler:

Each 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 clothes cylinder until one rib is at the bottom, then place a level on the bottom rib. The side-to-side level should be checked by placing a level on the front and rear of the top panel.

IMPORTANT: DO NOT block airflow at the top rear of the tumbler with laundry, etc. Doing so 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.

IMPORTANT: Install tumblers with sufficient clearance for servicing and operating.

NOTICE: CLEARANCE OF TUMBLER CABINET FROM COMBUSTIBLE CONSTRUCTION MUST BE A MINIMUM OF 12 INCHES (30.5 cm) AT THE TOP.

• 0″ clearance is permitted for the first 4″ (10.16 cm) from the front.

• A maximum of 4″ (10.16 cm) is allowed for the front overhang.

• A minimum of 12″ (30.5 cm) clearance is required at the top.

• At the rear, a minimum of 24″ (61 cm) is required, with 36″ (91.4 cm) recommended for maintenance purposes.

• 0″ clearance is allowed on the sides.

Cams that allow other timer increments are available through your distributor.

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.

REMOVAL OF EXISTING TIMING 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. Lift gently off the shaft. Make sure that 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 the timing cam 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. For gas models only: Turn on 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 the cylinder does not stop rotating, adjust the cylinder door interlock (refer to Adjustment Section).

6. Load the tumbler with clothes or clean rags.

7. For gas models only: Start the tumbler and check the burner flame, adjust the gas inlet shutter if necessary (refer to Adjustment Section).

8. Check 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 (refer to Adjustment Section).

9. Turn off the tumbler.

10. Check air flow 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.

The SPEED QUEEN JC75CE tumbler comes equipped with Electronic Control. The Electronic Control 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 set at the factory for proper operation. Steam models do not have an air flow switch. However, if there is a problem with the airflow switch, it should be adjusted as follows:

NOTICE: The control panel must be in place and the access door closed before attempting to adjust the air flow switch.

IMPORTANT: The air flow switch disc must remain closed during operation. If it opens and closes during the drying cycle, this indicates insufficient air flow 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, obstructions in the vertical recirculation stack, or in the customer-installed main or collector ducts. These conditions must be checked and necessary corrections made before adjusting the air flow switch. Always adjust air flow at installation.

Electric Models: If the switch remains open, or pops open and closed during the cycle, the heating system will shut off. The cylinder and fan will continue to operate even though the air flow switch is malfunctioning.

Adjustment Steps:

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 and adjustment.

3. If the switch is not opening as described in step “2”, it should be adjusted 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 the switch operates as described in step “2”.

4. If the switch opens BEFORE the lint panel is opened the proper distance, it should be adjusted to be LESS sensitive. Depress the spring clip and move the counterweight away from the disc. Retest by opening the lint panel and continue moving the counterweight away from the disc until the switch operates as described in step “2”.

The loading door switch turns off the tumbler any time the loading door is opened. To adjust the loading door switch, follow these steps:

1. Start the tumbler following the operating instructions that accompanied it.

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 when the loading door is closed 3″ (7.5 cm) plus or minus 1/4″ (0.635 cm):

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 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 against it. 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, and turn the door strike screw in or out as required. 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.

3. To tighten the V-belt:

a. Loosen the lower nut on the adjusting bolt.

b. Turn the bolt up until the belt has proper tension.

c. Tighten the upper and lower nut or adjusting bolt.

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 requires no adjustment since 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 lint 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 lint screen hood allow lint to flow into the ductwork system, restricting air circulation.

7. Wipe any accumulated lint off the thermostat sensing probe. Lint buildup on the sensing probe will cause overheating of the tumbler.
