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.

Gas, Electric or Steam Drying Tumblers:

• One circuit breaker.

Steam Drying Tumblers Only:

• One steam shut-off gate valve for steam service line to be connected upstream of solenoid steam valve.

• Two steam shut-off gate valves for each condensate return line.

• Flexible steam hoses with a 125 psig (pounds per square inch gauge) (8.79 kg/sq. cm) working pressure for connecting steam coils.

• Two steam traps for steam coil outlet to condensate return line.

• One steam pressure relief valve rated at 125 psig. (8.79 kg/cm²).

FLOOR

The SPEED QUEEN SCB75CSH 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. Doing so 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.

For maximum efficiency and performance, it is preferred to exhaust tumbler(s) individually to outdoors. At no point may the cross area of installed venting be less than the cross area of the exhaust thimble of the tumbler.

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). 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:

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.

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

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 opening to 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.

AWARNING: 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 the 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.

AWARNING: 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 SCB75CSH 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 circuit conductors and connected to the PE Busbar.

AWARNING: To reduce the risk of fire and electric shock, check with a qualified serviceman for proper ground procedures. Improper connection of the equipment grounding conductor can result in a risk of electric shock.

AWARNING: To reduce the risk of fire and electric shock, if electrical supply is coming from a three phase service, DO NOT connect a “Stinger Leg” to a single phase machine.

AWARNING: 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 electrical service phase sequence (three phase only).

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

To check the electrical service phase sequence (three phase only), follow these steps:

a. Energize the electrical service and momentarily start the tumbler. Check the direction of the cylinder rotation. If the cylinder rotates clockwise (viewed from 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.

The tumbler may be removed from its 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 remove 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.

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 adequate air supply to the tumbler’s heat chamber.

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

A typical tumbler enclosure can touch the tumbler top and side panels. Note the following minimum and maximum dimensions. Be aware that there may be local codes and ordinances which must also be complied with.

• Top Clearance: 12″ (30.5 cm) minimum.

• Side Clearance: 0″ clearance permitted for the first 4″ (10.16 cm) from the front, then a maximum of 4″ (10.16 cm).

• Rear Clearance: 24″ (61 cm) minimum, 36″ (91.4 cm) recommended for maintenance purposes.

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

High pressure machines require a (constant) 80 to 100 psig (5.62 to 7.03 kg/sq. cm) steam service for optimum operation. Low pressure machines require a (constant) 10 to 15 psig (.70 to 1.05 kg/sq. cm) steam service for optimum operation. The size of the steam service pipe is dependent upon many variables (length, tees, high pressure system, low pressure system, etc.). Specific pipe size information should be obtained from the steam system supplier or a qualified steam fitter.

The following steps outline the procedure for installing the steam solenoid valve and connecting steam service:

a. Install a manual shut-off gate valve in the condensate return line after the steam trap for each coil.

b. Connect the steam solenoid valve to the related steam coil inlet connection with nipples, flex hoses, unions, tee, and pressure relief valve.

c. Install a gate shut-off valve in the steam supply line. Connect the shut-off gate valve outlet to the solenoid steam valve inlet connection.

AWARNING: The flexible steam hoses connecting the solenoid steam valve to the coil inlets must have a 125 psig (pounds per square inch gauge) (8.79 kg/sq. cm) working pressure. A shut-off gate valve must be installed upstream from the solenoid steam valve. This way, steam can be shut off for maintenance purposes, or in the event the hose ruptures. The steam solenoid valve must be supported so minimum load is exerted on the steam coil inlet connections.

A steam trap must be installed and coil outlet connections must be connected to condensate return lines. The following steps outline the procedure:

a. Connect a flexible hose to each steam coil outlet.

b. Install a strainer to the ends of each flexible hose.

c. Install a steam trap to each strainer.

IMPORTANT: The steam trap must be installed a minimum of 10 inches (25.4 cm) below the steam coil outlet connections.

d. Install a gate shut-off valve to each steam trap.

e. Connect to condensate return lines.

AWARNING: The flexible steam hoses connecting the coil outlet connections and steam traps must have a minimum of 125 psig (pounds per square inch gauge) (8.79 kg/sq. cm.) working pressure. A shutoff gate valve must be installed downstream from each steam trap so the condensate return line can be isolated in the event a steam trap requires maintenance. Each steam trap must be supported so minimum load is exerted on the coil outlet connection.

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

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

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.

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.

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.

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 metered time expires, the motor will stop, indicating the drying cycle is finished.

The 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 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 which 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 at the specified 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 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.

AWARNING: 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.
