  • Page 16: 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 2 feet (0.60 meters) 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 dryer front.

  • Page 17: 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 18: 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 19 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. 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.
  • Page 20 It is suggested that the ductwork from each dryer (minimum 14-inches [35.56 cm]) not exceed 20 feet (6.09 meters) with no more than three (3) elbows (including dryer connections and outside exhaust outlets). If the ductwork exceeds 20 feet (6.09 meters) or has numerous elbows, the cross section area of the ductwork must be increased in proportion to the length and number of elbows in it.
  • Page 21 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 exhaust 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 22 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 exhaust 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 29: Steam Information

    H. STEAM INFORMATION It is your responsibility to have ALL steam plumbing connections made by a qualified professional to ensure that the 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 30 3. Installation Instructions To ensure that an adequate supply of steam is provided, be sure that the steam supply lines and steam return lines are sized and laid out as stipulated in this manual. Inadequate steam supply and steam return lines or improper steam plumbing will result in poor performance and can cause component failure.
  • Page 31 4. Steam Damper Air System Connections The dryer is manufactured with a pneumatic (piston) damper system, which requires an external supply of compressed air of 4.25 cfh (0.12 cmh) (refer to Section M for further compressed air requirements). The air connection is made to the steam damper solenoid valve which is located at the rear inner top area of the dryer just above the electric service relay box (refer to the illustration below).

  • Page 32: Water Information

    I. WATER INFORMATION BEFORE YOU START! CHECK LOCAL CODES AND PERMITS Call your local water company or the proper municipal authority for information regarding local codes. IMPORTANT: It is your responsibility to have ALL plumbing connections made by a qualified professional to assure that the plumbing installation is adequate and conforms to local, state, and federal regulations or codes.
  • Page 33 NOTE: The 3/4”-11.5 NH is a standard hose coupling screw thread. It is not to be confused with 3/4” N.P.T. The sealing of an NH connection is made with a washer opposed to the mating threads of an N.P.T. assembly. The two (2) thread designs are not compatible. IMPORTANT: Flexible supply line/coupling must be used.

  • Page 34: Preparation For Operation

    WARNING: If the water in the supply line or water solenoid valve freezes, the fire suppression system will be INOPERATIVE!! The manual ball cock shutoff valve must be located outside of the dryer at a distance from the dryer where it is easily accessible.

  • Page 35: Preoperational Tests

    K. 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 36 b. Steam Models Check to ensure that the steam damper is functioning properly. 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 37: Preoperational Instructions

    L. PREOPERATIONAL INSTRUCTIONS 1. The L.E.D. display reads “READY” (no cycle in progress). 2. Press the letter on the keypad corresponding to the cycle desired (i.e., key “D”). NOTE: “0-40” WILL REQUIRE THE “START/ENTER” KEY TO BE PRESSED AFTER THE NUMBER IS SELECTED IN ORDER TO ACCEPT THE SELECTION AND START DRYING.

  • Page 38: Compressed Air Requirements

    REVERSING TIMER SPIN/DWELL ADJUSTMENTS Timer models have an electronic reversing timer in the electrical service box, which is located in the upper left rear area of the dryer. Both the Dwell (stop) Time and the basket (tumbler) Spin Time are adjustable by mode selection switches located on the electronic timer (as noted in the illustration below).

  • Page 39: Shutdown Instructions

    3. Air Connection Air connection to this system is a 1/4” quick connection. N. SHUTDOWN 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.

  • Page 43: Section Vi: Routine Maintenance

    Maximum operating efficiency is dependent upon proper air circulation. The accumulation of lint can restrict this airflow. If the guidelines in this section are met, an ADC dryer will provide many years of efficient, trouble free, and most importantly, safe operation.

  • Page 44: Adjustments

    90 DAYS Remove lint from around basket (tumbler), drive motors, and surrounding areas. Remove lint from the gas valve burner area with a dusting brush or vacuum cleaner attachment. Impellor/fan (blower) shaft bearings should be lubricated using Shell Alvania #2 grease or its equivalent. Generically, this grease would be described as an NLGI grade 2 multipurpose industrial grease with a lithium thickener and mineral base oil.

  • Page 45: Lubrication

    C. LUBRICATION The fan shaft bearings and ALL the basket (tumbler) drive shaft and idler shaft bearings must be lubricated every 3 months. Use Shell Alvania #2 grease or its equivalent. Lubrication is necessary or premature bearing failure will be the result. The motor bearings are permanently lubricated and DO NOT require to be serviced.
