The following are the specifications for the 75 Pound (34 kg) Steam Tumblers like the SPEED QUEEN SC75CSH.

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 advise the carrier as soon as it is discovered. A written claim should be filed immediately if articles are damaged or missing.

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

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

The following materials should be obtained locally for installation:

For All Tumblers:

• One circuit breaker.

For Steam Drying Tumblers Only (like the SPEED QUEEN SC75CSH):

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

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

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

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

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

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.

Venting: For maximum efficiency and minimum lint accumulation, tumbler air must be exhausted to the outdoors by the shortest possible route.

Make-Up Air: A tumbler is a forced air exhausted unit and requires provisions for make-up air to replace the air it exhausts. The recommended make-up air opening is 195 square inches (1258 sq. cm).

Properly sized exhaust ducts are essential. All elbows should be sweep type. Ducts must be assembled so interior surfaces are smooth. Do not use sheet metal screws to join vent sections. Improperly sized or assembled ductwork causes excess back pressure, leading to slow drying, lint collection, and fire hazard.

Exhaust ducts must be constructed of sheet metal or other noncombustible material, equivalent in strength 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. At no point may the cross area of installed venting be less than the cross area of the tumbler’s exhaust thimble. The maximum allowable length of venting is 14 feet (4.3 m) with two 90° elbows or equivalent. The following table shows the equivalent length of straight duct for a 90° elbow:

Collector Venting:

A main collector duct may be used if sized properly. 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. The collector system must be designed so static back pressure does not exceed the maximum allowable pressure specified on the installation sticker on the rear of the tumbler.

The following tables show the electrical requirements for the 75 Pound (34 kg) steam tumblers. The SC75CSH is a high pressure steam model.

REQUIREMENTS

HIGH PRESSURE STEAM DRYING TUMBLERS

NOTE: DO NOT use aluminum wire.

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.

2. Perform the following 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 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, 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 by unscrewing the four shipping capscrews at each corner. The lint panel door may need 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 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 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.

High pressure machines like the SC75CSH require a constant 80 to 100 psig (5.62 to 7.03 kg/sq. cm) steam service for optimum operation.

Installing Steam Solenoid Valve and Making Steam Inlet Connections:

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

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

3. 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.

WARNING: The flexible steam hoses connecting the solenoid steam valve to the coil inlets must have a 125 psig working pressure. A shut-off gate valve must be installed upstream from the solenoid steam valve. The steam solenoid valve must be supported so minimum load is exerted on the steam coil inlet connections.

Installing Steam Trap and Making Condensate Return Connections:

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

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

3. Install a steam trap to each strainer. The steam trap must be installed a minimum of 10 inches (25.4 cm) below the steam coil outlet connections.

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

5. Connect to the condensate return lines.

WARNING: The flexible steam hoses connecting the coil outlet connections and steam traps must have a minimum of 125 psig working pressure. A shutoff gate valve must be installed downstream from each steam trap so the condensate return line can be isolated for maintenance.

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. (Gas models only) Turn on gas supply at manual gas shut off valve in gas supply line.

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. (Gas models only) Start the tumbler and check the burner flame, adjust the gas inlet shutter if necessary.

8. (Gas and Electric models) 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.

9. Turn off the tumbler.

10. (Gas and Electric models) 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.

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.

The loading door switch turns off the tumbler any time the loading door is opened. To adjust, 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 a tumbling load. 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 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 belt (Poly V-belt) is self-adjusting and requires no adjustment.
