In the absence of such codes or ordinances the location must conform with the National Fuel Gas Code ANSI.Z223.1 LATEST EDITION, or in Canada, the installation must conform to applicable Canadian Standards: CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGA-B149.2-M91 (L.P.

  • Page 11: Dryer Enclosure Requirements

    C. DRYER ENCLOSURE REQUIREMENTS Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of 12-inches (30.48 cm) above the dryer’s outer top; 18-inches (45.72 cm) for steam dryers, except along the front of the dryer which may be closed if desired.

  • Page 12: Fresh Air Supply Requirements

    D. FRESH AIR SUPPLY REQUIREMENTS This appliance may only be installed in a room that meets the appropriate ventilation requirements specified in the national installation regulations. The air supply (make-up air) must be given careful consideration to assure proper performance of each dryer. An unrestricted source of air is necessary for each dryer.

  • Page 13: Exhaust Requirements

    E. 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-limit, or lint chamber hi-heat protector thermostat. The dryer must be installed with a proper exhaust duct connection to the outside.
  • Page 14 SINGLE DRYER VENTING IMPORTANT: For exhaust duct runs over 25 feet (7.62 meters) a minimum size of 10-inches (25.4 cm) must be used. HORIZONTAL VENTING When a single 8-inch (20.32 cm) horizontal vent is used, the ductwork to the outlet cannot exceed 25 feet (7.62 meters) refer to Illus.
  • Page 15 VERTICAL VENTING When vertical single 10-inch (25.4 cm) venting is used (refer to Illus. B below), the ductwork from the dryer to the outside outlet cannot exceed 40 feet (12.19 meters) (refer to Illus. B below). This calculation compensates for the use of a maximum of three (3) elbows including the two (2) elbows creating the 180°...
  • Page 16 MULTIPLE DRYER (COMMON) VENTING If it is not feasible to provide separate exhaust ducts for each dryer, ducts for individual dryers may be channeled into a common main duct.

    F. ELECTRICAL INFORMATION 1. Electrical Requirements It is your responsibility to have ALL electrical connections made by a properly licensed and competent electrician to assure that the electrical installation is adequate and conforms to local and state regulations or codes. In the absence of such codes, ALL electrical connections, materials, and workmanship must conform to the applicable requirements of the National Electrical Code ANSI/NFPA NO.
  • Page 19 2) Electric Models ONLY ALL electrically heated dryers must be connected to the electric service shown on the dryer’s data label, which is affixed to either the backside of the upper control door or left side panel/wall area behind the control door. The connecting wires must be properly sized to handle the rated current. NOTE: Electrically heated service (amperage) specifications/requirements are not available at the time of printing.
  • Page 20 INGLE HASE Ø LECTRICAL ONNECTIONS EADS Black White Green White Neutral Ground If local codes permit, power to the dryer can be made by the use of a flexible UL listed power cord or pigtail (wire size must conform to rating of dryer), or the dryer can be hard wired directly to the service breaker panel.
  • Page 21 5. 3-Phase (3ø) Wiring Connections / Hookup 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 is done internally to the dryer. No single- phase (1ø) input connection is required on a 3-phase (3ø) dryer.
  • Page 22 CAUTION: The dryer must be grounded. A ground lug has been provided for this purpose. IMPORTANT: A CIRCUIT SERVICING EACH DRYER MUST BE PROVIDED. The only electrical connections to the dryer are the 3-phase (3ø) leads (L1, L2, L3, and sometimes Neutral) and ground.

Gas) or LATEST EDITION (for General Installation and Gas Plumbing), as well as local codes and ordinances and must be done by a qualified professional.
  • Page 27 NOTE: Undersized gas supply piping can create a low or inconsistent pressure, which will result in erratic operation of the burner ignition system. Consistent gas pressure is essential at ALL gas connections. It is recommended that a 3/4-inch (19.05 mm) pipe gas loop be installed in the supply line servicing a bank of dryers.

  • Page 28: Steam Information

    H. STEAM INFORMATION It is your responsibility to have ALL plumbing connections made by a qualified professional to assure that the steam plumbing installation is adequate and conforms with local and state regulations or codes. Care must be exercised when leveling steam dryers into final position. After leveling the dryer, check the downward pitch of the heat exchanger from front to rear with a level.
  • Page 29 a. The presence of condensate in the steam supply will cause water hammer and subsequent heat exchanger (steam coil) failure. The steam supply connection into the main supply line must be made with a minimum 10-inch (25.4 cm) riser. This will prevent any condensate from draining towards the dryer. b.
  • Page 30 4. Steam Damper Air System Connections The dryer is manufactured with a pneumatic (piston) damper system, which requires an external supply of compressed air. The air connection is made to the steam damper solenoid valve, which is located at the rear inner top area of the dryer just in front of the electric service relay box.
  • Page 31 5. Steam Damper System Operation The steam damper, as shown in the illustration below, allows the coil to stay constantly charged eliminating repeated expansion and contraction. When the damper is opened, the air immediately passes through the already hot coil, providing instant heat to start the drying process. When the damper is closed, ambient air is drawn directly into the tumbler, allowing a rapid cool down.
  • Page 32 6. Steam Damper Air Piston (Flow Control) Operation Adjustment Damper operation was tested and adjusted prior to shipping at 80 PSI (5.51 bar). If damper air adjustment is necessary, locate the flow control valve and make the necessary adjustments as noted below. American Dryer Corp.

  • Page 33: Preparation For Operation / Start-Up

    I. PREPARATION FOR OPERATION / START-UP The following items should be checked before attempting to operate the dryer: 1. Read ALL “CAUTION,” “WARNING,” and “DIRECTION” labels attached to the dryer. 2. Check incoming supply voltage to be sure that it is the same as indicated on the dryer data label affixed to the left side panel area behind top control (access) door.

  • Page 34: Preoperational Test

    J. PREOPERATIONAL TEST ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test should be performed before the dryer is publicly used. It is possible that adjustments have changed in transit or due to marginal location (installation) conditions. Installer must instruct the user on how to correctly operate the dryer before leaving.

  • Page 35: Preoperational Instructions

    NOTE: The sail switch can be checked for proper operation by opening the lint drawer. While pushing the lint drawer switch in, start a drying cycle. The heating unit should not activate (wait 30-seconds). If heat does activate, make the necessary adjustments to the sail switch. 5.
  • Page 36 d. Once the preprogrammed dryness level and cool down period have been reached, or the maximum automatic time has expired, the tone (buzzer) will sound for 5-seconds, and the L.E.D. display will read “donE,” at which time the dryer will shut off. NOTES: 1.
  • Page 37 b. Select Temperature... The dryer will start, the L.E.D. display will read the temperature cycle selected, and the drying time portion of the L.E.D. display will read “00” and count upward as time elapses, or the vended time will count downward, depending on the program parameter setting.
