  • Page 17: Dryer Enclosure Requirements

    C. DRYER ENCLOSURE REQUIREMENTS Even though a 12-inch (30.48 cm) clearance is acceptable, it is recommended that the rear of the dryer be positioned approximately 24-inches (60.96 cm) from the nearest obstruction (i.e., wall) for ease of installation, maintenance, and service. Bulkheads and partitions should be made from noncombustible materials. 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 18: Fresh Air Supply Requirements

    D. FRESH AIR SUPPLY REQUIREMENTS 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 19: Exhaust Requirements

    E. EXHAUST REQUIREMENTS 1. General Exhaust Ductwork Information 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, overheating of the dryer, and shutdown of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler) hi-heat thermostats.
  • Page 20 a. Outside Ductwork Protection 1) 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.
  • Page 21 It is suggested that the ductwork from each dryer not exceed 20 feet (6.09 meters) with no more than two (2) elbows (excluding dryer connections). If the ductwork exceeds 20 feet (6.09 meters) or has numerous elbows, the cross-sectional area of the ductwork must be increased in proportion to the length and number of elbows in it.
  • Page 22 IMPORTANT: For extended ductwork runs, the cross section area of the ductwork can only be increased to an extent. Maximum proportional ductwork runs cannot exceed 20 feet (6.09 meters) more than the original limitations of 20 feet (6.09 meters) with two (2) elbows.

  • Page 24: Electrical Information

    IMPORTANT: For extended ductwork runs, the cross section area of the ductwork can only be increased to an extent. Maximum proportional ductwork runs cannot exceed 20 feet (6.09 meters) more than the original limitations of 20 feet (6.09 meters) with two (2) elbows.

  • Page 30 IMPORTANT: The dryer and its individual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa). NOTE: The dryer must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure test of the gas supply system at test pressures equal to or less than 1/2 psig (3.5 kPa).

  • Page 31: Steam Information

    H. STEAM INFORMATION It is your responsibility to have ALL plumbing connections made by a qualified professional to assure that the gas plumbing installation is adequate and conforms to local and state regulations or codes. IMPORTANT: Failure to comply with the requirements stipulated in this manual can result in component failure, which will VOID THE WARRANTY.
  • Page 32 a. The pressure of the condensate in the steam supply line 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 12-inch (30.48 cm) riser. This will prevent any condensate from draining towards the dryer.

  • Page 33: Com Pressed Air Supply

    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 of the top console.
  • Page 34 6. Steam Damper Air Piston (Flow Control) Operation Adjustment Although the steam damper operation was tested and adjusted prior to shipping at 80 PSI (5.51 bar), steam damper operation must be checked before the dryer is put into operation. Refer to page 33 for instructions to check steam damper operation.

  • Page 35: 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 that is affixed to the left side panel/wall area behind the control door (refer to the illustration on page 9).

  • Page 36: Preoperational Tests

    J. 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 37 b. Steam Models 1) Check to insure that the steam damper is functioning properly. a) The steam damper should not “slam” (open or closed) when it reaches the end of (piston) travel. Additionally, the steam damper should not bind and/or stop during travel. If either of these conditions occur, the flow control must be adjusted.

  • Page 38: Compressed Air Requirements

    K. COMPRESSED AIR REQUIREMENTS The dryer requires an external supply of compressed air (2.5 cfh at 80 PSI [0.07 cmh at 5.51 bar] for gas models and 3.25 cfh at 80 PSI [0.09 cmh at 5.51 bar] for steam models). For steam models, compressed air is necessary for the air operated steam damper.

  • Page 39: Shutdown Instructions

    L. SHUTDOWN INSTRUCTIONS If the dryer is to be shutdown (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.

  • Page 40: Service/Parts Information

    SERVICE/PARTS INFORMATION A. SERVICE 1. Service must be performed by a qualified trained technician, service agency, or gas supplier. If service is required, contact the reseller from whom the ADC equipment was purchased. If the reseller cannot be contacted or is unknown, contact the ADC Service Department for a reseller in your area. NOTE: When contacting the ADC Service Department, be sure to give them the correct model number and serial number so that your inquiry is handled in an expeditious manner.

  • Page 41: Warranty Information

    WARRANTY INFORMATION A. RETURNING WARRANTY CARDS 1. Before any dryer leaves the ADC factory test area, a warranty card is placed on the back side of the main door glass. These warranty cards are intended to serve the customer where we record the individual installation date and warranty information to better serve you should you file a warranty claim.

  • Page 43: Routine Maintenance

    ROUTINE MAINTENANCE A. CLEANING A program and/or schedule should be established for periodic inspection, cleaning, and removal of lint from various areas of the dryer, as well as throughout the ductwork system. The frequency of cleaning can best be determined from experience at each location. Maximum operating efficiency is dependent upon proper air circulation.
  • Page 44 STEAM DRYERS Clean the steam coil fins. Compressed air and a vacuum cleaner with brush attachment are suggested. NOTE: When cleaning steam coil fins, be careful not to bend the fins. If fins are bent, straighten by using a fin comb, which is available from any local air conditioning supply house. 90 DAYS Remove lint from around basket (tumbler), drive motors, and surrounding areas.

  • Page 45: Adjustments

    B. ADJUSTMENTS 7 DAYS AFTER INSTALLATION AND EVERY 6 MONTHS THEREAFTER Inspect bolts, nuts, screws, (bearing setscrews), grounding connections, and nonpermanent gas connections (i.e., unions, shutoff valves, and orifices). Motor and drive belts should be examined. Cracked or seriously frayed belts should be replaced. Tighten loose V-belts when necessary. Complete operational check of controls and valves.
