  • Page 23 a. Reassembly For 2 Door/Rear Tilt (Pass Thru) Gas Dryers: Lift the basket (tumbler) section onto the base. 1) Rear tilt dryers have two (2) tilting pistons. The two (2) pistons are in the front corners of the base and there are two (2) piston posts in the rear corners of the base. On the top of both tilting pistons and both piston posts are clevis blocks.
  • Page 24 B. LOCATION REQUIREMENTS The tilt model dryer requires 18-inches (45.72 cm) on the right side of the dryer for ease of service. For the left side clearance on a 1 door dryer is 18-inches (45.72 cm), and for a 2 door dryer 36-inches (91.44 cm) is required due to the side exhaust.
  • Page 25 C. 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 26 D. EXHAUST REQUIREMENTS NOTE: For 1 door dryers, the 24-inch (60.96 cm) diameter exhaust duct exits from the rear of the base. For 2 door dryers, the 24-inch (60.96 cm) diameter exhaust duct exits from the left side of the base. 1.
  • Page 27 The internal dimensions of the dryer’s rectangular exhaust vent ductwork is 8-1/2” x 21-inches (20.6 cm x 53.5 cm). A transition piece to 24-inches (60.96 cm) in diameter round is supplied. The location’s exhaust duct must be at least 24-inches (60.96 cm) in diameter or, for a rectangular duct, have a cross-sectional area of 452 square inches (2,916 square centimeters).
  • Page 30 a. Outside Ductwork Protection 1) To protect the outside end of horizontal ductwork from the weather, a 90º 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 180º turn to point the opening downward.
  • Page 31 E. COMPRESSED AIR SUPPLY SYSTEM The compressed air supply system of the tilting dryer consists of a number of pneumatic pistons located throughout the dryer. The pistons are actuated by solenoid and flow control valves that are under computer control. The pneumatic pistons are used to: -Tilt the Dryer For Loading and Unloading -Open and Close The Load and Unload Doors...
  • Page 32 3. Optional Automatic (Piston Operated) Load/Unload Doors If the dryer is equipped with the automatic door option then the loading doors are operated by two (2) pneumatic pistons located above the load doors. On 2 door dryers, the unloading doors on the back of the dryer will also be controlled by two (2) pistons, located above the unload doors.
  • Page 33 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, material, and workmanship must conform to the applicable requirements of the National Electrical Code ANSI/NFPA NO.
  • Page 34 WARNING: 208 VAC and 230 VAC ARE NOT THE SAME. Any damage done to dryer components due to improper voltage connections will automatically VOID THE WARRANTY. NOTE: ADC reserves the right to make any changes in specifications at any time without notice or obligation.
  • Page 35 3. Electrical Connections NOTE: A wiring diagram is included with each dryer and is located in the blueprint pocket inside the left side control cabinet. The main electrical input connections to the dryer are the 3-phase (3ø) power leads (L1, L2, and L3), GROUND, and in the case of 4 wire service, the Neutral.
  • Page 36 The adjustment of the dryers in the field for elevations over 2,000 feet (609.6 meters) are made by changing each burner orifice. If this conversion is necessary, contact the reseller who sold the dryer or contact the ADC factory.
  • Page 37 2. Technical Gas Data a. Gas Specifications Natural Gas Manifold Pressure* 3.5 inches W.C. Inline Pressure - 12.0 inches - 29.9 mb 6.0 inches W.C. 14.92 mb Shaded areas are stated in metric equivalents * Measured at gas valve pressure taps when the gas valves are on. b.
  • Page 38 Consistent gas pressure is essential at ALL gas connections. It is recommended that a 2-inch (5.08 cm) 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 (29.9 mb) of water column (W.C.) pressure.
  • Page 39 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 testing of the gas supply piping system at test pressures equal to or less than 1/2 psig (3.5 kPa).
  • Page 40 7. When the programmed drying time has expired, the Phase 7 OPL microprocessor controller (computer) will proceed into the Cool Down Cycle (Mode). 8. Once the Cool Down Cycle begins at the end of the heat cycle the L.E.D. display will read COOL DOWN TEMP ___/___MINUTE REMAINING.
  • Page 41 If one (1) burner lights and the other does not, then the system will shut both burners off and the burner fault code will be displayed showing which of the two (2) burners failed to ignite. NOTE: During the purging period, verify that ALL gas shutoff valves are open. 3) Once ignition is established, a gas pressure test should be taken at each gas valve pressure tap of the dryer to assure that the water column (W.C.) pressure is correct and consistent.
  • Page 42 4. GAS MODELS - The sail switch damper assembly was installed and adjusted at the factory prior to shipping. However, each sail switch adjustment must be checked to assure that this important safety control is functioning. 5. GAS MODELS - Be sure that ALL gas shutoff valves are in the open position. 6.
