Unpacking/Setting Up _________________

Remove protective shipping material (i.e., plastic wrap and optional shipping box) from the dryer.

Important

!Dryer must be transported and handled in an upright position at all times.

The dryer can be moved to its final location while still attached to the skid or with the skid removed. To remove the skid from the T20, simply lift the unit off of the skid; for the T30, T50, or T75, locate and remove the 2 bolts securing the base of the dryer to the wooden skid. One is located at the center rear and the other is at the center front.

With the skid removed, use caution and assure all four leveling legs are fully retracted if the dryer is to be slid into its final position.

Leveling Dryer

The dryer is equipped with 4 leveling legs, 1 at each corner of the base. For optimum performance the dryer should be level front-to-backandside-to-side.

Dryer Enclosure Requirements _______

Commercial Type II

JLA Limited

113429 - 9

Domestic Type I (T20, T30, T50 Only)

A = 6-inches(15.24 cm)

B = 24-inches(60.96 cm)

EXAMPLE: For T50, 2 unrestricted openings measuring 6-inchesby24-inches(15.24 cm by 60.96 cm) are acceptable.

If a closet door is installed: unobstructed air openings are required. The air openings shall be located 3-inches(7.62 cm) from the lower opening (above floor level) and upper opening (below ceiling). The total free area of the air openings in the door shall not be less than 130 inch2 (838.708 cm2) for T20; 179 inch2 (1154.836 cm2) for T30; and 293 inch2 (1890.319 cm2) for T50. Louvered doors with equivalent air openings are acceptable.

No other fuel-burningappliance shall be installed in the same closet as the dryer.

Fresh Air Supply Requirements _______

When the dryer is operating, it draws in room air, heats it, passes this air through the tumbler, and exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. If the make-upair is inadequate, drying time and drying efficiency will be adversely affected. Ignition problems and sail switch “fluttering” problems may result, as well as premature motor failure from overheating. The dryer must be installed with provisions for adequate combustion andmake-upair supply.

Air supply (make-upair) must be given careful consideration to ensure proper performance of each dryer. As a general rule, an unrestricted air entrance from the outdoors of 110 inch2 (710 cm2) is required for each T75, 90 inch2 (580 cm2) for each T50, 55 inch2 (354 cm2) for each T30, and 40 inch2 (258 cm2) for each T20. (Based on 1 inch2 [6.5 cm2] per 1,000 Btu [252 kcal].)

It is not necessary to have a separate make-upair opening for each dryer. Commonmake-upair openings are acceptable. However, they must be set up in such a manner that themake-upair is distributed equally to all the dryers.

To compensate for the use of registers or louvers used over the openings, this area must be increased by approximately 33%. Make-upair openings should not be located in an area directly near where exhaust vents exit the building.

Allowances must be made for remote or constricting passageways or where dryers are located at high altitudes or predominantly low pressure areas.

Note

!Component failure due to dry cleaning solvent fumes will void the warranty.

A = 10-inches(25.4 cm)

B = 11-inches(27.94 cm)

EXAMPLE: For a bank of 4 T30 dryers, 2 unrestricted openings measuring 10-inchesby11-inches(25.4 cm by 27.94 cm) are acceptable.

Important

!Make-upair must be free of dry cleaning solvent fumes.Make-upair that is contaminated by dry

cleaning solvent fumes will result in irreparable damage to the motors and other dryer components.

Exhaust Requirements________________

Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork will create excessive back pressure, which results in slow drying, increased use of energy, and shutdown of the burner by the airflow (sail) switch, burner hi-limits,or lint chamberhi-limitprotector thermostat. The dryer must be installed with a proper exhaust duct connection to the outside.

The dryer shall not be exhausted into any gas vent, chimney, wall, ceiling or concealed space of a building.

Caution

!This dryer produces combustible lint and must be exhausted to the outdoors.

Improperly sized or installed exhaust ductwork can create a potential fire hazard.

The ductwork should be laid out in such a way that the ductwork travels as directly as possible to the outdoors with as few turns as possible. There should be a minimum 6-inch(15.24 cm) clearance between the back guard and the first bend in the ductwork for ease of servicing. Single or independent dryer venting is recommended. It is suggested that the use of 90° turns be avoided; use 30° and/or 45° bends instead. The radius of the elbows should preferably be1-1/2times the diameter of the duct. All ductwork should be smooth inside with no projections from sheet metal screws or other obstructions, which will collect lint. When adding ducts, overlap the duct being connected. All ductwork joints must be taped to prevent moisture and lint from escaping into the building. Back draft dampers must be installed in all commonly ducted systems. Inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning of lint from the ductwork.

Important

!It is recommended that exhaust or booster fans not be used in the exhaust ductwork system.

113429 - 9

Telephone 01422 822282

15

Important

! Exhaust back pressure measured by a manometer/magnehelic in the exhaust duct must

be no less than 0 and must not exceed 0.6 in WC (1.48 mb).

Note

!When the exhaust ductwork passes through a wall, ceiling, or roof made of combustible materials, the

opening must be 2-inches(5.08 cm) larger than the duct (all the way around). The duct must be centered within this opening.

As per the National Fuel Gas Code, “Exhaust ducts for type 2 clothes dryers shall be constructed of sheet metal or other noncombustible material. Such ducts shall be equivalent in strength and corrosion resistance to ducts made of galvanized sheet steel not less than 26 gauge (0.0195-inches[0.50 mm]) thick.”

The ductwork for this appliance must be suitable for the appliance category in accordance with national installation regulations of the country of destination.

Outside Ductwork Protection

To protect the outside end of the horizontal ductwork from the weather, a 90° elbow bent downward should be installed where the exhaust exits the building. If the ductwork travels vertically up through the roof, it should be protected from the weather by using a 180° turn to point the opening downward. In either case, allow at least twice the diameter of the duct between the duct opening and the nearest obstruction (refer to the diagram).

Important

!Do not use screens, louvers, or caps on the outside opening of the exhaust ductwork.

Single Dryer Venting

Important

!For extended ductwork runs, the cross-sectionalarea of the ductwork can only be increased to an

extent. When the ductwork approaches the maximum limits as noted in this manual, a professional HVAC firm should be consulted for proper venting information.

Horizontal Venting

When horizontal dryer venting is used, the length of the ductwork from the dryer to the outside exhaust outlet, must not exceed 20 feet (6.10 meters). The minimum diameter of this ductwork must be at least 4-inches(10.16 cm) for T20,6-inches(15.24 cm) for T30, and8-inches(20.32 cm) for T50 and T75. Including tumbler/dryer elbow connections or elbows used for outside protection from the weather, no more than 1 elbow should be used in the exhaust duct run. If more than 1 elbow is used, thecross-sectionalarea of the ductwork must be increased.

Vertical Venting

When vertical dryer venting is used, the length of the ductwork from the dryer to the outside exhaust outlet, must not exceed 12 feet (3.66 meters). The minimum diameter of this ductwork must be at least 4-inches(10.16 cm) for T20,6-inches(15.24 cm) for T30, and8-inches(20.32 cm) for T50 and T75. Including tumbler/dryer elbow connections or elbows used for outside protection from the weather, no more than 3 elbows should be used in the exhaust duct run. If more than 3 elbows are used, thecross-sectionalarea of the ductwork must be increased.

Multiple Dryer (Common) Venting

Important

!For extended ductwork runs, the cross-sectionalarea of the ductwork can only be increased to an

extent. When the ductwork approaches the maximum limits as noted in this manual, a professional HVAC firm should be consulted for proper venting information.

If it is not feasible to provide separate exhaust ducts for each dryer, ducts from individual dryers may be channeled into a “common main duct.” The individual ducts should enter the bottom or side of the main duct at an angle not more than 45º in the direction of airflow. The main duct should be tapered, with the diameter increasing before each individual duct is added.

Grounding

A ground (earth) connection must be provided and installed in accordance with local, state, and national regulations or codes of the country of origin. In the absence of these codes, grounding must conform to applicable requirements of the National Electrical Code ANSI/NFPA NO. 70-LATESTEDITION, or in Canada, the installation must conform to applicable Canada Standards: Canadian Electrical Codes Parts 1 & 2 CSAC22.1-1990or LATEST EDITION. The ground connection may be to a proven earth ground at the location service panel.

For added personal safety, when possible, it is suggested that a separate ground wire (size per local codes) be connected from the ground connection of the dryer to a grounded cold water pipe. Do not ground to a gas pipe or hot water pipe. The grounded cold water pipe must have metal-to-metalconnection all the way to the electrical ground. If there are any nonmetallic interruptions, such as, a meter, pump, plastic, rubber, or other insulating connectors, they must be jumped out with a wire (size per local codes) and securely clamped to bare metal at both ends.

Important

!For personal safety and proper operation, the dryer must be grounded.

Provisions are made for ground connection in each dryer at the electrical service connection area.

Warning

!Electrical Grounding Instructions – This dryer is equipped with a 3-prong(grounding) plug for your

protection against shock hazard and should be plugged directly into a properly grounded 3-prongreceptacle. Do not cut or remove the grounding prong from this plug.

Electrical Connections

A wiring diagram is located behind the control panel for connection data.

If local codes permit, power to the dryer can be made by the use of a flexible UL listed power cord/pigtail (wire size must conform to rating of dryer), or the dryer can be hard wired directly to the service breaker panel. In both cases, a strain relief must be installed where the wiring enters the dryer.

For CE Models Only

The means for disconnection from the supply must be incorporated into wiring having a minimum contact separation of 3.0mm in all poles.

Single-Phase(1ø)

Wiring Connections/Hookup

The electrical input connections are made into the rear service box located at the upper right area of the dryer. The ground connection is made to the copper lug, also provided in this box. To gain access, the service box cover must be removed.

Caution

!The dryer must be grounded. A ground lug has been provided for this purpose.

Input connection wiring must be sized properly to handle the dryer’s current draw. This information is printed on the dryer’s data label.

Important

!A strain relief must be used where the input wiring enters the oven assembly.

Electrically Heated Models Only

The electrical input connections are made at the rear service box located at the right upper section of the dryer. The ground connection is made to a copper lug also provided in this area. To gain access, remove rear service cover.

The only electrical input connections to the dryer are the 3-phase(3ø) power leads (L1, L2, L3, and sometimes neutral) and ground.Single-phase(1ø) power for the control circuit and for anysingle-phase(1ø) motors (if present) is done internally to the dryer by the factory at the oven contactor. Nosingle-phase(1ø) input connection is required on a3-phase(3ø) dryer.

The neutral will only be used on 4-wireservice. This is typical for380-416V,50 Hz.

Caution

!The dryer must be grounded. A ground lug has been provided for this purpose.
