  • Page 33: Location Requirements

    B. LOCATION REQUIREMENTS Before installing the dryer, be sure the location conforms to local codes and ordinances. In the absence of such codes or ordinances the location must conform with the National Fuel Gas Code ANSI.Z223.1 LATEST EDITION, or in Canada, the installation must conform to applicable Canadian Standards: CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGA-B149.2-M91 (Liquid Propane [L.P.] Gas) or LATEST EDITION (for General Installation and Gas Plumbing).
  • Page 34: Fresh Air Supply Requirements

    C. FRESH AIR SUPPLY REQUIREMENTS When the dryer is operating, it draws in room air, heats it, passes this air through the 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 efficiency will be adversely affected.
  • Page 35: Exhaust Requirements

    D. EXHAUST REQUIREMENTS NOTE: For 1 door dryers, the 20-inch (50.8 cm) diameter exhaust duct exits from the rear of the base. For 2 door dryers, the 20-inch (50.8 cm) diameter exhaust duct exits from the left side of the base.
  • Page 36 The internal dimensions of the dryer’s rectangular exhaust vent ductwork are 8-inches x 20-inches (20.3 cm x 50.8 cm). A transition piece 20-inches (50.8 cm) in diameter round is supplied. The location’s exhaust duct must be the minimum exhaust size requirement of the ductwork (20-inches [50.8 cm] round duct or 315 square inches [2,032 square centimeters] square duct) from the dryer to the outside exhaust outlet for a horizontal run, with no more than one (1) elbow must not exceed 30 feet (9.14 meters) for gas and 20 feet (6.09 meters) for steam dryers.

  • Page 40 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 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 41: Compressed Air Supply System

    E. COMPRESSED AIR SUPPLY SYSTEM The compressed air 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: •...
  • Page 42 3. Internal/External Pilot Air Supply On 2-way tilt dryers, a pneumatic safety circuit is incorporated to prevent both front and rear tilting pistons from extending their rods at the same time. When 24 volts is supplied to the “12” side of the front tilting piston solenoid valve coil, the round internal spool in the core of the solenoid will move, allowing 80 psi (5.51 bar) air to flow into the bottom ports of the front tilting pistons, while the top ports are bled to the atmosphere.

  • Page 54 4. Steam Damper System Operation The dryer’s steam damper in the Heating Mode as shown in Diagram 1, allows the coil to stay constantly charged eliminating repeated expansion and contraction. When the damper is opened, the air immediately passes through the already hot coil, providing instant heat to start the drying process. When the damper is closed, ambient air is drawn directly into the tumbler, allowing a rapid cool down.
  • Page 55: Steam Damper Actuator System

    I. STEAM DAMPER ACTUATOR SYSTEM The system consists of a hinged damper plate, pneumatic piston, and a 24 volt solenoid valve with a needle valve to control the speed of the piston actuation. On a call for heat, a 24 volt signal is applied to the 3-way/2-position solenoid valve. This signal switches the valve so that compressed air is sent to the piston.
  • Page 56: Preoperational Test

    K. PREOPERATIONAL TEST 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.
  • Page 57 NOTE: Dryer can be stopped at any time by opening the main door or by pressing the “CLEAR/ STOP” key. To restart the dryer, press the “ENTER/START” key or a preprogrammed cycle key (i.e., “E”). NOTE: Pressing touchpad key “A,” “B,” “C,” “D,” or “F” will also start the dryer. The six preprogrammed drying cycles (“A”...
  • Page 58: Preparation For Operation/Start-Up

    2) Make a complete operational check of ALL safety-related circuits (i.e., lint drawer switch and sail switches on gas models). 3) Reversing tumbler dryers should never be operated with less than a 100 lb (45.4 kg) load (dry weight), since the load’s weight affects tumbler coast time during a direction reversal command. It is important that the tumbler come to a complete stop prior to starting in opposite direction.
  • Page 59: Shutdown Instructions

    9. Rotate the tumbler (drum) by hand to be sure it moves freely. 10. Check bolts, nuts, screws, terminals, and fittings for security. 11. Check to ensure air supply (80 psi [5.51 bar]) is connected to the dryer. 12. STEAM MODELS – check to ensure ALL steam shutoff valves are open. M.

  • Page 63: Routine Maintenance

    SECTION VI 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.
  • Page 64 MONTHLY Empty the compressed air filter bowl. EVERY 3 MONTHS Clean lint accumulation from the gas valve/burner area at the top of the dryer, the fan (impellor) motor, and the fan/impellor bearings located in the dryer base. NOTE: To prevent damage, avoid cleaning and/or touching ignitor/flame-probe assembly. EVERY 6 MONTHS Check fan (impellor) and drive motor V-belts for tightness and wear.
  • Page 65: Adjustments

    B. ADJUSTMENTS 7 DAYS AFTER INSTALLATION AND EVERY 6 MONTHS THEREAFTER Inspect bolts, nuts, screws (bearing setscrews), non-permanent gas connections (unions, shutoff valves, orifices, and grounding connections). Motor and drive belts should be examined. Cracked or seriously frayed belts should be replaced.
  • Page 66: Component System Descriptions

    SECTION VII COMPONENT SYSTEM DESCRIPTIONS A. TUMBLER DRIVE SYSTEM The tumbler is supported and driven by four (4) 11-inch (27.94 cm) diameter drive wheels. Two (2) of these wheels are attached to a 1-1/2” (3.81 cm) diameter idler shaft, while the other two (2) are attached to a 1-1/2” (3.81 cm) diameter drive shaft.
  • Page 67: Tumbler

    B. TUMBLER The tumbler is made of 14-gauge stainless steel perforated panels, four (4) stainless steel ribs, and two (2) outer tumbler rings made of rolled steel angle iron that has been turned on a lathe for smoothness. The tumbler is a completely welded assembly so the perforated panels are not removable.

System will extinguish fires that may start in the drying tumbler. A series of sensors positioned throughout the tumbler and interfaced with the microprocessor will trigger the S.A.F.E.
  • Page 74 If the rear area of the dryer, or the water supply is located in an area where it will be exposed to cold/freezing temperatures, provisions must be made to protect these water lines from freezing. WARNING: If the water in the supply line or water solenoid valve freezes, the S.A.F.E. system will be INOPERATIVE!! IMPORTANT: Appliance is to be connected to the water mains using a new hose set and the old hose set should not be reused.
  • Page 75: Optional Manual Bypass

    OPTIONAL MANUAL BYPASS Provisions are made in the dryer’s S.A.F.E. system for the installation of an optional manual bypass. Depending on the model dryer, the connections for the manual bypass are made at the “T” or “four way” fitting located in the outlet supply side of the water solenoid valve.
