    4. Installation and service must be performed by a qualified installer, service agency, or gas supplier. 5. Dryer(s) must be exhausted to the outdoors. 6. Although ADC produces a very versatile machine, there are some articles that, due to fabric composition or cleaning method, should not be dried in it.
  • Page 9 7. A program should be established for the inspection and cleaning of lint in the burner area, exhaust duct work, and area around the back of the dryer. The frequency of inspection and cleaning can best be determined from experience at each location. WARNING: The collection of lint in the burner area and exhaust duct work can create a potential fire hazard.

    (2) bolts located in the lint chamber area, remove the lint door. To increase bearing life and improve efficiency, the dryer should be tilted slightly to the rear. The lint coops of ALL ADG-758 dryers are supported during shipping by a bracket. REMOVE THIS BRACKET BEFORE STARTING THE DRYER.

  • Page 16: 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) - (18-inches [45.72 cm] or more is recommended for ease of installation, maintenance, and service) - above the dryer outer top, except along the front of the dryer which may be partially closed in if desired. The clearance between the bulkhead header and the dryer must be a minimum of 4-inches (10.16 cm) and must not extend more than 4-inches (10.16 cm) to the rear of the front.

  • Page 17: Fresh Air Supply

    D. FRESH AIR SUPPLY When the dryer is operating, it draws in room air, heats it, passes this air through the basket (tumbler), and exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors. If the make-up air is inadequate, drying time and drying efficiency will be adversely affected.

  • Page 18: Exhaust Requirements

    E. EXHAUST REQUIREMENTS 1. General Exhaust Duct Work Information Exhaust duct work should be designed and installed by a qualified professional. Improperly sized duct work will create excessive back pressure which results in slow drying, increased use of energy, overheating of the dryer, and shutdown of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler) hi-heat thermostats.
  • Page 19 NOTE: Where the exhaust duct work passes through a wall, ceiling, or roof made of combustible materials, the opening must be 2-inches (5.08 cm) larger (all the way around) than the duct. The duct must be centered within this opening. a.
  • Page 20 IMPORTANT: For extended duct work runs, the cross section area of the duct work can only be increased to an extent. When the duct work approaches the maximum limits noted in this manual, a professional heating venting air conditioning (HVAC) firm should be consulted for proper venting information.
  • Page 21 3. Multiple (common) Dryer Venting IMPORTANT: For extended duct work runs, the cross section area of the duct work can only be increased to an extent. When the duct work approaches the maximum limits noted in this manual, a professional heating venting air conditioning (HVAC) firm should be consulted for proper venting information.

  • Page 26 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. For gas dryers manufactured for operation at 3-phase (3ø), the electrical connections are made at the power distribution block located in the service box at the rear, upper left corner of the dryer.
  • Page 27 ø 3) 3-Phase (3 ) Wiring Connections (Hookup) - for NON-REVERSING MODELS ONLY ø The electrical connections on ALL 3-phase (3 ) gas model dryers are made into the rear service box located at the upper left area of the dryer. NOTE: A CIRCUIT SERVING EACH DRYER MUST BE PROVIDED.

It is important that gas pressure regulators meet applicable pressure requirements and that gas meters be rated for the total amount of ALL the appliance BTU's (kilocalories) being supplied. The dryer is provided with a 3/4"...
  • Page 31 Consistent gas pressure is essential at ALL gas connections. It is recommended that a 3/4 inch (1.91 cm) pipe gas loop be installed in the supply line serving 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 - 29.9 millibars - pressure.

  • Page 32: Preparation For Operation/Start-Up

    H. 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 back side of the top front control/service door.

  • Page 33: Preoperational Tests

    I. PREOPERATIONAL 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 34 4. 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. IMPORTANT: The dryer basket (tumbler) is treated with a protective coating. ADC suggests tumbling old clothes or material in the basket (tumbler), using a mild detergent to remove the protective coating.

  • Page 35: Preoperational Instructions

    7. REVERSING MODELS ONLY -basket (tumbler) dryer should never be operated with less than a 30 lb. (13.61 kg) load (dry weight). The size of the load will affect the coast- down and dwell (stop) times. The basket (tumbler) must come to a complete stop before starting in opposite direction.

  • Page 36: Shut Down Instructions

    K. SHUT DOWN INSTRUCTIONS If the dryer is to be shut down (taken out of service) for a period of time, the following MUST BE performed; 1. Discontinue power to the dryer either at the external disconnect switch or the circuit breaker. 2.
