To assure compliance, consult local building code requirements. The tumble dryer must not be installed or stored in area where it will be exposed to water and/ or weather.

IMPORTANT: DO NOT block the airflow at the rear of the tumble dryer with laundry or other articles. Doing so would prevent adequate air supply to the combustion chamber of the tumble dryer.

A typical tumble dryer enclosure is shown in Figure 1. Note the minimum and maximum dimensions. Local codes and ordinances must be complied with.

Installation

Position and Level the Tumble Dryer

The tumble dryer may be moved with or without the skid. To remove the skid, unscrew the four shipping bolts, and discard them.

To fit a 170 pound tumble dryer (with shipping skid) through an 8 foot (2.43 meters) high door, you must remove the front access panel. The upper 3 inches (76 mm) of the stove must also be removed on 170 pound gas tumble dryers. Removing the entire gas or steam heater assembly and the shipping skid, will reduce the height of the 120 pound tumble dryer to 70 inches (1778 mm), and the 170 pound tumble dryer to 75 inches (1905 mm).

Level the tumble dryer to within 0.125 inch (3 mm) from front-to-rear (level on cylinder rib), and side-toside (level on top panel). Shim under corners to level and stabilize unit. Tumble dryer must not rock.

Before Placing Tumble Dryer into Service

1. Remove or open all panels and check accessible bolts, nuts, screws, terminals and fittings for tightness.

2. Check V-belt tension and adjust if necessary. Refer to appropriate paragraphs in Adjustments Section.

3. Replace all panels and guards.

4. Turn on electrical supply to tumble dryer.

5. Open supply valve for gas or steam heated tumble dryers.

6. After performing the previous checks, start the tumble dryer by pressing START (hold for approximately 3 seconds). Release the start button and open the loading door. The cylinder should stop rotating within 7 seconds after the door is opened.

7. Gas tumble dryers: Start the tumble dryer and check the burner flame. Adjust the gas inlet shutter as required. Refer to Adjustments section.

IMPORTANT: The Electronic Ignition system will attempt to light the gas by sparking for the “trial for ignition” period. If gas does not ignite within this period, the ignition control will go into a safety lockout and the valve will no longer open until the control is reset. Refer to Tab le 1. It may be necessary to restart several times to bleed air out of gas lines. To reset, open and close loading door, then start.

), or L.P.

) in the countries

Models are built in two different configurations:

 Regulated Natural Gas – Injector is sized for

Natural Gas, second family, group H (E) at 20 mbar inlet pressure. Regulator/governor is operational. Gas valve CAN be field converted to a non-regulating type.

 Unregulated L.P. (Liquefied Petroleum) Gas –

Injector is sized for L.P. Gas, third family, group 3+ at 28.37 mbar inlet pressure. Regulator/ governor is blocked open. Gas valve CAN be field-converted to a regulating type.

Serial plates supplied from the factory are configured for the countries of GB/IE/PT/ES/IT/GR/LU/CH. These instructions pertain to the situations when the country of use or gas supply is different than that on the serial plate.

Tab l e 2 describes the different gases that are available in different CE countries, and how the machines need to be configured to operate with those gases. In the CE, there are Natural Gas configurations that do not allow for machine regulation, and L.P. Gas configurations that must be regulated. For L.P. Gas, third family B/P at 50 mbar, order Regulated Natural Gas machines and convert according to Tab l e 2 .

Exhaust Requirements

A drying tumble dryer produces combustible lint. To reduce the risk of fire, the tumble dryer must be exhausted to the outdoors.

W057R1

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, ceiling, crawl space under a building, or concealed space of a building.

W506

WARNING

To reduce the risk of fire due to increased static pressure, we do not recommend installation of in-line secondary lint filters or lint collectors. If secondary systems are mandated, frequently clean the system to assure safe operation.

W749

Layout

Wherever possible, install tumble dryers along an outside wall, where duct length can be kept to a minimum and makeup air can be easily accessed. Construction must not block the airflow at the top rear of the tumble dryer. Doing so would prevent adequate air supply to the tumble dryer combustion chamber.

Make-up air openings with louvers will restrict air flow. The opening must be increased to compensate for area taken up by louvers.

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

Venting

Make-Up Air

A tumble dryer is forced air exhausted and requires provisions for make-up air to replace air exhausted by tumble dryer. Refer to Ta bl e 3 .

IMPORTANT: Do not obstruct flow of combustion and ventilation air.

IMPORTANT: Installing in-line filters or lint collectors will cause increased static pressure. Failure to maintain the secondary lint system will decrease tumble dryer efficiency and may void machine warranty.

For maximum efficiency and minimum lint accumulation, tumble dryer must be exhausted to the outdoors by the shortest possible route.

Proper sized exhaust ducts are essential for proper operation. All elbows should be sweep type. Exhaust ducts must be assembled so the interior surfaces are smooth, so the joints do not permit the accumulation of lint. DO NOT use plastic, thin foil or Type B flexible ducts – rigid metal ducts are recommended. Use exhaust ducts made of sheet metal or other noncombustible material. Use of duct tape or poprivets on all seams and joints is recommended, if allowed by local codes.

Verify that old ducts are thoroughly cleaned before installing new tumble dryer(s).

25

Exhaust Requirements

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.

W355

WARNING

T496I

CUT

NOTE: Exhaust ducts must 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 inch (0.495 mm) thick.

Where the exhaust duct pierces a combustible wall or ceiling, the opening must be sized per local codes. The space around the duct shall be sealed with noncombustible material.

NOTE: For best performance, provide an individual exhaust duct for each tumble dryer. Do not install a hot water heater in a room containing tumble dryers. It is better to have the water heater in a separate room with a separate air inlet.

Alternate Venting for 120 Pound tumble dryers

The 120 pound tumble dryer is equipped from the factory to exhaust from the top; however, it may be converted to exhaust out the rear by doing the following (refer to Specifications and Dimensions section):

1. Remove belt guard cover.

2. Remove 10 inch (254 mm) diameter elbow and vertical duct.

3. Cut out shape from belt guard cover. Refer to Figure 5.

4. Screw octagonal piece over 10 inch (254 mm) diameter opening in top of belt guard.

5. Attach new exhaust duct to exhaust thimble on rear panel, following all requirements in this section.

6. Replace belt guard cover.

70420801 (EN)

Exhaust Requirements

Individual Venting

For maximum efficiency and performance, it is preferred to exhaust tumble dryer(s) individually to the outdoors.

IMPORTANT: At no point may the cross sectional area of installed venting be less than the cross sectional area of the exhaust outlet of the tumble dryer.

The exhaust duct must be designed so the static back pressure measured 12 inches (305 mm) from the exhaust outlet does not exceed the maximum allowable pressure specified on the installation sticker on the rear of the tumble dryer.

NOTE: Static back pressure must be measured with the tumble dryer running.

The maximum allowable length of venting of the same diameter as the exhaust thimble is 14 feet (4.3 meters) 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 meters). Cross section area of a rectangular duct must be increased by 20% for each additional 20 feet (6.1 meters). Refer to Tabl e 4 to determine equivalent venting:

NOTE: The maximum length of a flexible metal duct must not exceed 7.87 ft. (2.4 m) as required to meet UL2158, claus 7.3.2A.

Manifold Venting

While it is preferable to exhaust tumble dryers individually to the outdoors, a main collector duct may be used if it is sized according to Figure 8. This illustration indicates minimum diameters, and should be increased if collector length exceeds 20 feet (6.1 meters). Manifold duct may be rectangular in cross section, as long as area is not reduced. Provisions should be made for lint removal and cleaning of duct.

Manifold duct must be tapered, as shown in Figure 6. Individual tumble dryer ducts must enter manifold duct at a 45° angle in the direction if airflow.

NOTE: Never connect a tumble dryer duct at a 90° angle to a collector duct. Refer to Figure 6. Doing so will cause excessive back pressure, resulting in poor performance. Never connect two tumble dryer exhaust ducts directly across from each other at the point of entry to manifold duct.

Duct Diameter

10 in. (254 mm) 12 in. (305 mm) 14 in. (356 mm) 16 in. (406 mm) 18 in. (457 mm)

Equivalent Length (ft.) = 1.17 x Duct Diameter (in.)

Example: A 12 inch (305 mm) diameter duct’s equivalent length of 14 feet (4.3 meters) of duct and two 90° elbows is:

Equivalent Length: = 14 ft. (4.3 m) + (2) 90° elbows

One 90° elbow = 11.6 ft. (3.5 m) One 90° elbow = 14 ft. (4.3 m) One 90° elbow = 16 ft. (4.9 m) One 90° elbow = 18.7 ft. (5.7 m) One 90° elbow = 21 ft. (6.4 m)

Equivalent Length

of Rigid Straight Duct

Table 4

= 14 ft. (4.3 m) + 14 ft. (4.3 m)

+ 14 ft. (4.3 m)

= 42 ft. (12.8 m)

With the tumble dryer in operation, airflow at any point in the duct should be at least 1200 feet per minute (366 meters per minute) to ensure that lint remains airborne. If 1200 feet per minute (366 meters per minute) cannot be maintained, schedule monthly inspections and cleaning of the ductwork.

T438I

Figure 6

Exhaust system must be designed so static back pressure measured 12 inches (305 mm) from exhaust thimble does not exceed maximum allowable pressure specified on installation sticker on rear of tumble dryer. This must be measured with all tumble dryers running that are vented into collector.

With the tumble dryer in operation, airflow at any point in the duct should be at least 1200 feet per minute (366 meters per minute) to ensure that lint remains airborne. If 1200 feet per minute (366 meters per minute) cannot be maintained, schedule monthly inspections and cleaning of the ductwork.

WARNING

To reduce the risk of fire or explosion, DO NOT CONNECT THE GAS LINE TO THE TUMBLE DRYER IF THE GAS SERVICE IS NOT THE SAME AS THAT SPECIFIED ON THE TUMBLE DRYER SERIAL PLATE! It will first be necessary to convert the gas burner orifice and gas valve. Appropriate conversion kits are available.

W060R1

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 0.5 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 0.5 psig (3.45 kPa).

W061R2

WARNING

To reduce the risk of fire or explosion, if the tumble dryer is to be connected to Liquefied Petroleum (L.P.) gas, a vent to the outdoors must be provided in the room where the tumble dryer is installed.

W062R1

IMPORTANT: Any product revisions or conversions must be made by the Manufacturer’s Authorized Dealers, Distributors or local service personnel.

The following must be furnished and installed by the customer for the gas service line to each tumble dryer. Refer to Figure 10.

 Sediment traps

 Shut-off valves

 Supply pressure taps

It is important that equal pressure be maintained at all tumble dryer gas connections. This can be done by installing a one inch (25 mm) pipe gas loop. Refer to Figure 11.

IMPORTANT: The installation must comply with local codes or, in the absence of local codes:

 with the latest edition of the “National Fuel

Gas Code,” ANSI Z223.1/NFPA 54 in the U.S.A.

Electrical Requirements

To reduce the risk of electric shock, fire, explosion, serious injury or death:

• Disconnect electric power to the tumble dryer before servicing.

• Close gas shut-off valve to gas tumble dryer before servicing.

• Close steam valve to steam tumble dryer before servicing.

• Never start the tumble dryer with any guards/panels removed.

• Whenever ground wires are removed during servicing, these ground wires must be reconnected to ensure that the tumble dryer is properly grounded.

W002R1

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 may result in a risk of electric shock.

W068

To reduce the risk of fire and electric shock, if electrical supply is coming from a three phase service, DO NOT connect a “High Leg” or “Stinger Leg” to a single phase machine. On a three phase machine, if there is a “High Leg” or “Stinger Leg” it should be connected to L3.

W069

WARNING

In case of servicing (or putting the tumble dryer out of order), disconnect the tumble dryer from the main supply by switching off the circuit breaker.

W796

IMPORTANT: Electrical connections must be made by a qualified electrician using data on serial plate, installation manuals and wiring diagram provided with machine and according to local codes. Install a circuit breaker as close to the tumble dryer as possible. If more than one tumble dryer is being installed, a circuit breaker must be provided for each.

NOTE: Connect machine to an individual branch circuit not shared with lighting or other equipment.

NOTE: 3 Phase Machines Only - Do not use fuses to avoid the possibility of “single phasing” and causing premature failure of the motors.

NOTE: To ensure protection against shock, this tumble dryer MUST be electrically grounded in accordance with the local codes or, in the absence of local codes, with the latest edition of the National Electrical Code ANSI/NFPA No. 70. In Canada the electrical connections are to be made in accordance with CSA C22.1 latest edition Canadian Electrical Code, Part I and/or local codes. Electrical work should be done by a qualified electrician.

Grounding Instructions

This tumble dryer must be grounded. In the event of malfunction or breakdown, grounding will reduce the risk of electric shock by providing a path of least resistance for electric current. This tumble dryer 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 appropriate ground location.

Metal conduit and/or BX cable is not considered ground. Connecting the Neutral from the electrical service box to the tumble dryer ground screw does not constitute a ground. A dedicated ground conduit (wire) must be connected between the electrical service box ground bar and the tumble dryer ground screw.

70420801 (EN)

For CE Models Only

All electrical connections should be made by a qualified electrician.

To reduce the risk of electrical shock, deenergize the electrical circuit being connected to the tumble dryer before making any electrical connections. Never attempt to connect a live circuit.

W070R1

WARNING

Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

W071

Steam Requirements

WARNING

All system components must have a 125 psig (8.6 bar) working pressure. Shut-off valves must be installed upstream of the steam solenoid valve and downstream of each steam trap so components can be isolated for maintenance or emergency purposes.

All components (solenoid valve, traps) must be supported to minimize loads on the tumble dryer steam coil connections.

W480R2

NOTE: Machines require a constant 80 to 100 psig (5.62 to 7.03 kg/sq. cm) steam service for optimum operation. The maximum allowable steam pressure for use with 60 Hertz or 50 Hertz tumble dryers is 125 psig (8.6 bar). In no case may the pressure exceed the above value. Drying performance is significantly reduced at lower steam pressures.

Obtain specific steam service pipe sizes from steam system supplier or a qualified steam fitter.

 Refer to Figure 14 and Figure 15 for proper

steam pipe configurations.

 To prevent condensate draining from headers to

tumble dryer, piping should have a minimum 12 inch (305 mm) rise above respective header. Do not make steam connection to header with a horizontal or downward facing tee or elbow.

 Whenever possible, horizontal runs of steam

lines must drain, by gravity, to respective steam header. Water pockets or an improperly drained steam header will provide wet steam, causing improper operation of tumble dryer. If pockets or improper drainage cannot be eliminated, install a bypass trap to drain condensate from the low point in the steam header to the return.

NOTE: To prevent water hammering, route return lines below outlets of steam coils.

Piping Recommendations

 Trap each steam coil individually. Always keep

the trap clean and in good working condition.

 When tumble dryer is on the end of a line of

equipment, extend header at least 4 feet (1.2 meters) beyond tumble dryer. Install shut-off valve, union, check valve and bypass trap at end of line. If gravity return to boiler, omit trap.

 Insulate steam supply and return line for safety of

operator and safety while servicing tumble dryer.

 Keep tumble dryer in good working condition.

Repair or replace any worn or defective parts.

 In both steam supply and steam return line, it is

recommended that each have a pipe union and shut-off valve. This will enable you to disconnect the steam connections and service the tumble dryer while your laundry facility is in operation.

 Connect the steam solenoid valve to the related

steam coil inlet connection with nipples, flex hoses, unions and tee.

 Strainers may require cleaning due to materials

from hoses or pipes.

 Install vacuum breaker (optional), bucket trap

with built-in strainer and check valve. For successful operation of tumble dryer, install trap 18 inches (457 mm) below coil and as near to the tumble dryer as possible. Inspect trap carefully for inlet and outlet markings and install according to trap manufacturer's instructions. If steam is gravity returned to boiler, omit trap but install vacuum breaker and check valve in return line near tumble dryer.

 Gravity return requires entire return plumbing be

below steam coil outlets.

 Install union and shut-off valve in return line and

make final pipe connections to return header.

The steam trap must be installed and the coil outlet connections must be connected to the condensate return lines. The following steps outline the procedure for installing the steam trap and connecting the condensate return lines. Refer to Figure 14 and Figure 15 for typical installations.

1. Use flexible lines between steam inlet solenoid and steam coils, as well as outlet between steam coil and traps.

2. If necessary, install a strainer to the end of each flexible hose.

3. Install a steam trap to each strainer.

IMPORTANT: Steam trap must be installed a minimum of 18 inches (457 mm) below the steam coil outlet connections.

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

5. Connect to the condensate return lines.

6. For steam solenoid valve wiring connections, refer to Wiring Diagram supplied with tumble dryer.

Thermal Oil Prep

It is the responsibility of the customer to install appropriate coil and heating system for thermal oil prep models. Alliance Laundry Systems, LLC. is not responsible for the performance or safety of the customer installed thermal oil system. To ensure proper operation, refer to the Specifications and Dimensions section for the BTU input of equivalent steam models. Thermal oil systems that do not deliver appropriate BTUs will dry slower. For solenoid valve wiring connections, refer to the Wiring Diagram supplied with tumble dryer.

Adjustments

To reduce the risk of electric shock, fire, explosion, serious injury or death:

• Disconnect electric power to the tumble dryer before servicing.

• Close gas shut-off valve to gas tumble dryer before servicing.

• Close steam valve to steam tumble dryer before servicing.

• Never start the tumble dryer with any guards/panels removed.

• Whenever ground wires are removed during servicing, these ground wires must be reconnected to ensure that the tumble dryer is properly grounded.

Gas Burner Air Shutter

NOTE: 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 the inlet shutters, be sure that all lint is removed from lint compartments and lint screen.

Air shutter adjustment will vary from location to location and will depend on the vent system, number of units installed, make-up air and line gas pressure. Opening the shutter increases the amount of primary air supplied to the burner, while closing the shutter decreases the primary air supply. Adjust air shutter as follows:

4. Open or close air shutter as necessary to obtain proper flame intensity.

5. After air shutter is adjusted for proper flame, tighten air shutter adjusting screw securely.

Refer to Figure 16.

1. Remove the upper access panel and burner inspection hole plate.

2. Start the tumble dryer and check the flame pattern. If the flame pattern is straight up, insufficient air is flowing through the tumble dryer. A flame pattern that flares to the right and left indicates no air is flowing through the tumble dryer. Correct air and gas mixture is indicated if the flame pattern is primarily blue, with small yellow tips, and bends to the left of the heater section. Too little air is indicated if the flame is yellow, lazy and smoky.

3. To adjust the air shutter, loosen air inlet shutter adjusting screw.

Airflow Switch

The airflow switch is set at the factory for proper operation. No adjustment necessary.

The airflow switch operation may be affected by shipping tape still in place, lack of make-up air, or an obstruction in the exhaust duct. These should be checked and the required corrective action taken.

IMPORTANT: Airflow switch vane must remain closed during operation. If it opens and closes during the drying cycle, this indicates insufficient airflow through the tumble dryer. If 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 airflow switch is indicating insufficient airflow.

NOTE: To properly mount the airflow switch bracket, or in case of a load not drying, the airflow switch bracket may need to be checked for proper alignment. Be sure the locator pins are securely in their respective holes before tightening the bracket

Belt Drive

The drive assemblies consist of motors, belts, eyebolts and a step pulley.

The pulley diameters are sized to produce a cylinder speed of 37-39 RPM for 120 pound models or 29-31 RPM for 170 pound models.

The step pulley assembly is used for speed reduction as well as a means of adjusting belt tension. The pulley mounting plate is attached to the cabinet. The frame mounting plate has vertically slotted holes allowing up and down movement of the step pulley mounting plate for belt adjustment.

Adjust the belt tension as follows:

1. Disconnect electrical power to the tumble dryer before attempting any adjustments to the drive assembly.

2. Loosen pulley mounting plate bolts.

3. Loosen the upper nut on the final drive eyebolt.

4. Rotate the lower nut of the final drive eyebolt clockwise until proper belt tension is achieved.

5. Rotate upper nut clockwise against the lower nut in order to lock it into place.

6. Tighten pulley mounting plate bolts. Recheck belt tension.

7. If necessary, adjust the drive motor belt tension eyebolt using a similar procedure.

8. Adjust blower belt tension on 120 pound 50 Hertz tumble dryers and all 170 pound tumble dryers using a similar procedure.

NOTE: Proper tensions for new belts are 45-55 pounds for the motor belt, 55-65 pounds for the final drive, 60-65 pounds for 120 pound blower, and 75-80 pounds for 170 pound blower measured with a Borroughs Belt Tension Gauge. Using a Browning Belt Tension Gauge, the motor belt deflection should be 0.31 inch at five pounds pressure, and final drive belt deflection should be

0.25 inch at five pounds pressure.

Belts should not slip or make any noise when starting up under normal load.
