    INSTALLATION PROCEDURES Installation should be performed by qualified professionals in accordance with local and state codes. In the absence of these codes, installation must conform to applicable AMERICAN NATIONAL STANDARDS: ANSI Z223.1-LATEST EDITION (NATIONAL FUEL CODE) ANSI/NFPA No. 70-LATEST EDITION (NATIONAL ELECTRIC CODE) 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 13: Dryer Enclosure Requirements

    Even though a 12-inch clearance is acceptable, it is recommended that the rear of the dryer be positioned approximately 2 feet away from the nearest obstruction, i.e., wall, for ease of installation, maintenance, and service. 1. Leveling The Dryer To increase bearing life, improve efficiency, and provide for better automatic closure of main doors, the tumbler should be tilted slightly to the rear.

  • Page 14: Fresh Air Supply

    D. Fresh Air Supply Air supply (make-up air) must be given careful consideration to assure proper and safe performance of each dryer. An unrestricted source of air of 550 cfm is necessary for each tumbler. An unrestricted air entrace from the outdoors (atmosphere) of a minimum of 2 square feet is required for each dryer.

  • Page 15: Exhaust Requirements

    E. Exhaust Requirements General Information Exhaust duct work should be designed and installed by a competent technician. Improperly sized duct work will create excessive back pressure which results in slow drying, increased use of energy, and shutdown of the burner by airflow (sail) switch, burner hi-limit, or lint chamber hi-heat protector thermostat.
  • Page 16 IMPORTANT: Exhaust back pressure measured by a manometer at the dryer exhaust duct area must not exceed 0.3 inches of water column. NOTE: Careful consideration should be given to where the exhaust duct is located in relation to the make-up air openings. If make-up air opening is too close to exhaust outlet, lint and fumes will be drawn back in to the dryer area through these openings.
  • Page 17 The illustration below shows the duct work connection points and what internal duct work is included in the dryer. The exhaust connection at the TOP basket (tumbler) must be made at the blower duct inside the cabinet. No internal duct work is included for the TOP basket/tumbler. (Not available from ADC and must be purchased elsewhere).
  • Page 18 a. Connecting Both Top Baskets (Tumbler) and Bottom Baskets (Tumbler) Together Both the top basket (tumbler) and the bottom basket (tumbler) can “Y” together to form one connection point. The bottom basket (tumbler) already includes 6-inch diameter ducting extending to the lower back guard area. The minimum connection at this point is 8 inches.
  • Page 19 2. Single Dryer Venting Where possible, it is suggested that a separate exhaust duct be provided for each dryer. The exhaust duct work should be laid out in such a way that the duct work travels as directly as possible to the outdoors with as few turns as possible.
  • Page 21 b. Single Dryer Venting - with common (top basket [tumbler] and bottom basket [tumbler] connected together) exhaust connections. If the top and bottom baskets (tumblers) connect or “Y” together as noted is Section E1, the minimum diameter size at the “Y” or point of connections is 10 inches in diameter (80 square inches cross-sectional area).
  • Page 22 The main common duct may be any shape so long as the minimum cross-sectional area is provided. The main duct should be tapered with the diameter increasing before each individual duct is added as per the illustration [MAN2172] on page 19 and the illustration [MAN2171] on page 20. The maximum length of venting from the last dryer to where it exhausts is the following: VERTICAL -------- venting run must not exceed eight (8) feet.
  • Page 23 NOTE: The distance between the dryer single ducts being connected to the main common duct must be a minimum of 31-1/2 inches (the dryers width). NOTE: The duct work should be laid out in such a manner where allowances are made at the rear area of the dryer for removal of rear service panels/guards.
  • Page 24 These figures must be increased in proportion if the main duct run from the last dryer has numerous elbows or is unusually long. For extended runs or where more elbows are added, the cross-sectional area of the duct can only be increased to an extent and a professional HVAC firm should be consulted for proper venting information.
  • Page 25 IMPORTANT: No more then four (4) dryers (eight [8] baskets [tumblers]) can be connected to one (1) common duct (vent). NOTE: The distance between the dryer single ducts being connected to the main common duct must be a minimum of 31-1/2 inches (the dryers width). The duct work should be laid out in such a manner where allowances are made at the rear area of the dryer for removal of rear service panels/guards.
  • Page 26 Important Venting Reminders 1. Duct work sizing and installation should be done by a qualified professional. 2. The dryer must be vented to the outdoors. 3. The duct work should be routed as short as possible to the outdoors with as few turns 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 installations adequate and conforms with local and state regulations or codes. In the absence of such codes, ALL electrical connections, material, and workmanship must conform to the applicable requirements of the NATIONAL ELECTRIC CODE ANSI/NFPA NO.
  • Page 28 NOTE: IT IS REQUIRED that a circuit serving each basket (tumbler) be provided. 3. Grounding Grounding (earth ) connections 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 ELECTRIC CODES ANSI/NFPA NO.

  • Page 29: Gas Information

    The dryer must be isolated from the gas supply piping system by closing its individual manual shut-off valves during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa). AD-530HS ERVICE PECIFICATIONS WIRE APPROX.
  • Page 30 IMPORTANT: Failure to isolate or disconnect dryer from supply as noted can cause irreparable damage to the gas valves...VOIDING THE WARRANTY. WARNING: FIRE or EXPLOSION COULD RESULT. 1. Gas Supply The gas dryer installation must meet the AMERICAN NATIONAL STANDARD, NATIONAL FUEL GAS CODE ANSI Z223.1-LATEST EDITION or in Canada, the CANADIAN INSTALLATION CODES CAN/ CGA-B149.1-M91 (Natural Gas) or CAN/CGA-B149.2-M91 (L.P.
  • Page 31 NLET EACH BASKET NPUT EACH BASKET NPUT TOTAL FOR BOTH BASKETS N.P.T. = N ATIONAL Natural Gas Regulation is controlled by each gas valve’s internal regulator. Incoming supply pressure must be consistent between a minimum of 6.0 inches and a maximum of 12 inches water column pressure. c.
  • Page 32 IMPORTANT:Water column pressure of 4.0 inches for natural gas dryers and 10.5 inches for L.P. gas is required at the gas valve pressure tap of each dryer for proper and safe operation. A 1/8” N.P.T. plugged tap, accessible for a test gauge connection, must be installed in the main gas supply line immediately upstream of each dryer.

  • Page 33: Preparation For Operation

    H. Preparation For Operation The following items should be checked before attempting to operate the dryer: 1. Read and follow 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 located behind the left coin control panel, on the right wall (refer to SECTION IX [pages 48 and 49] of this manual).
  • Page 34 NOTE: The dryer can be stopped at any time by opening the main door. To restart dryer, shut the main door and press desired setting. 4) Open main door to stop dryer, and change selection to “PERM PRESS” (medium) setting. Repeat this procedure, but change the selection (setting) to “HIGH TEMP”.
  • Page 35 The dryer is equipped with a Hot Surface Ignition (HSI) system which has internal diagnostics. If ignition is not established after the first attempt, the heat circuit HSI module will try two (2) additional times and if a flame is not established the HSI module will lock out until it is manually reset. To reset the HSI system, open and close the main door and restart the dryer (press desired temperature selection).
