    SECTION I IMPORTANT INFORMATION A. RECEIVING AND HANDLING The dryer is shipped in a protective stretch wrap cover with protective cardboard corners and top cover (or optional box) as a means of preventing damage in transit. Upon delivery, the dryer and packaging, and wooden skid should be visually inspected for shipping damage.

  • Page 8: Safety Precautions

    4. Installation and service must be performed by a qualified installer, service agency, or gas supplier. 5. Dryers must be exhausted to the outdoors. 6. Although the MDG-50 is a very versatile dryer, there are some articles that, due to fabric composition or cleaning method, should not be dried in it.
  • Page 9 WARNING: DO NOT dry mop heads. Contamination by wax or flammable solvents will create a fire hazard. WARNING: DO NOT use heat for drying articles that contain plastic, foam, sponge rubber, or similarly textured rubber materials. Drying in a heated basket (tumbler) may damage plastics or rubber and may be a fire hazard.

    To increase bearing life and improve efficiency, the dryer should be tilted slightly to the rear. The lint coops of ALL MDG-50 model dryers are supported during shipping by a bracket. REMOVE THIS BRACKET BEFORE STARTING THE DRYER.

  • Page 13: Location Requirements

    B. LOCATION REQUIREMENTS Before installing the dryer, be sure the location conforms to local codes and ordinances. 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 (Liquid Propane [L.P.] Gas) or LATEST EDITION (for General Installation and Gas Plumbing) or Canadian Electrical Codes Parts 1 &...

  • Page 14: 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 above the dryer's outer top; 18-inches for locations with sprinkler systems, except along the front of the dryer, which may be closed if desired. NOTE: Allowances must be made for opening the control door.

  • Page 15: Fresh Air Supply Requirements

    D. FRESH AIR SUPPLY REQUIREMENTS The MDG-50 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. As a general rule, an unrestricted air entrance from the outdoors (atmosphere) of a minimum of 1-1/2 square feet is required for each dryer.

  • Page 16: 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 17: Horizontal Venting

    SINGLE DRYER VENTING IMPORTANT: For exhaust duct runs over 30 feet a minimum size of 10 inches must be used. HORIZONTAL VENTING When horizontal single 8-inch venting is used, the ductwork to the outlet cannot exceed 30 feet (refer to Illus. A below).

  • Page 18: Vertical Venting

    VERTICAL VENTING When vertical single 10-inch venting is used, the ductwork from the dryer to the outside outlet cannot exceed 60 feet (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 19 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. Each dryer is provided with a back draft damper. The individual ducts should enter the bottom or side of the main duct at an angle not more than 45°...
  • Page 20 HORIZONTAL VENTING ILLUS. C MAN4218 VERTICAL VENTING ILLUS. D. MAN4230...
  • Page 21 IMPORTANT VENTING REMINDERS 1. Ductwork size and installation should be done by a qualified professional. 2. The dryer must be exhausted to the outdoors. 3. Ductwork should be routed as short as possible to the outdoors with as few elbows as possible. 4.

    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 23 NOTE: Component failure due to improper voltage application will VOID THE WARRANTY. 3. Grounding A ground (earth) connection must be provided and installed in accordance with state and local codes. In the absence of these codes, grounding must conform to applicable requirements of the National Electrical Code ANSI/NFPA NO.
  • Page 24 INGLE HASE Ø LECTRICAL ONNECTIONS EADS Black White Green Positive Neutral Ground If local codes permit, power to the dryer can be made by the use of a flexible U.L. 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 25 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. IMPORTANT: A CIRCUIT SERVICING EACH DRYER MUST BE PROVIDED.
  • Page 26 M DG-50 (GAS) ELECTRICAL SERVICE SPECIFICATIONS (PER DRYER) IMPORTANT: 208 VAC AND 230/240 VAC ARE NOT THE SAME. When ordering, specify exact voltage. NOTES : A. When fuses are used they must be dual element, time delay, current limiting, class RK1 or RK5 ONLY.

  • Page 30 Consistent gas pressure is essential at ALL gas connections. It is recommended that a 3/4-inch pipe gas loop be installed in the supply line servicing a bank of dryers. An in-line pressure regulator must be installed in the gas supply line (header) if the (natural) gas pressure exceeds 12.0 inches of water column (W.C.) pressure.

  • Page 31: Preparation For Operation And Start-Up

    H. PREPARA TION FOR OPERATION AND 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 the top control (access) door.

  • Page 32: Preoperational Tests

    I. PREOPERA TIONAL TESTS 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. 1.

  • Page 33: Preoperational Instructions

    5. Make a complete operational check of ALL operating controls. NOTE: If computer program changes are required, refer to the computer programming section of the manual supplied with the dryer. 6. The dryer should be operated through one (1) complete cycle to assure that no further adjustments are necessary and that ALL components are functioning properly.
  • Page 34 NOTES: 1. If the anti-wrinkle program is active, the light emitting diode (L.E.D.) display will continue to read "donE," and the microprocessor controller (computer) will proceed through the anti-wrinkle program until the maximum "Active Guard Time" has expired or until the door is opened, whichever comes first.
  • Page 35 b. Select Temperature The dryer will start, the light emitting diode (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. IMPORTANT: If the door is opened during a cycle, both the heat and motor will stop.

  • Page 36: Shut Down Instructions

    2) Press the "E" on the keyboard (touch pad). 3) The light emitting diode (L.E.D.) display will quickly show "Ld30," "LC04," and "F180."
