  • Page 13: Fresh Air Supply Requirements

    B. 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 efficiency will be adversely affected.

    NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY. C. EXHAUST REQUIREMENTS IMPORTANT: Each AD-670 must be individually exhausted to the outdoors. 1. General Exhaust Ductwork Information Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork...
  • Page 15 IMPORTANT: Exhaust back pressure measured by a Magnehelic in the exhaust duct must be no less than 0 and must not exceed 1.0 inch (2.48 mb) of water column (W.C.). 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).

    1/2 psig (3.5 kPa). F. COMPRESSED AIR REQUIREMENTS The AD-670 requires compressed air to tilt the dryer, open and close the load doors, clean lint from the fan, and actuate the sprinkler valve. The dryer cannot operate without a supply of compressed air.

  • Page 23: Preoperational Tests

    G. 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 24 NOTE: Mechanical functions of the dryer are not allowed during the ON time. The blower (fan) must be OFF to perform mechanical functions. However the “STOP/CLEAR” key may be pressed at any time to end the Wrinkle Guard cycle. Mechanical functions of the dryer are allowed during the OFF time.

  • Page 25: Preparation For Operation/Start-Up

    12. Make a complete operational check of ALL safety-related circuits (i.e., lint drawer, door, and sail switches on gas models). 13. A reversing basket (tumbler) should never be operated with less than a 442 lb (200 kg) load (dry weight). The size of the load will affect the coast-down and dwell (stop) times.

  • Page 26: Shut Down Instructions

    NOTE: Lint drawer must be ALL the way in place to activate the safety switch otherwise the dryer will not start. 9. Check bolts, nuts, screws, terminals, and fittings for security. 10. Check to ensure air supply (80 PSI [5.51 bars]) is connected to the dryer. I.

  • Page 27: 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 28 MONTHLY Empty the compressed air filter bowl. Apply high-temperature grease to the four (4) 2-3/16” diameter basket (tumbler) drive shaft pillow block bearings. (Use Shell Alvania #2 grease or its equivalent.) Retighten setscrews in the collars of the four (4) 2-3/16” diameter basket (tumbler) drive shaft bearings. Clean any lint accumulation from the gas valve burner area at the right side of the dryer, the fan (impellor) motor, and the fan (impellor) bearings located in the dryer base.

  • Page 29: 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). Fan (impellor) V-belts, along with the motor and drive chains should be examined and replaced if necessary.

  • Page 35: Gas Train And Burner Description And Operation

    GAS TRAIN AND BURNER DESCRIPTION AND OPERATION The ADG-670’s atmospheric burner system is responsible for supplying the dryer with it’s heat input. It is a high/low system with a firing rate of 2.2 million BTUs per hour (554,400 kcal/hr) on hi-fire and 450,000 BTUs per hour (113,400 kcal/hr) on lo-fire.
  • Page 36 2. 1/2” N.P.T. Pilot Solenoid Valve – This is an on/off solenoid valve which is used to allow gas to flow through the line when pilot is called for and then discontinues gas when the heat cycle has been completed. There is no adjustment needed to this valve for natural or liquid propane (L.P.) gases.

  • Page 37: Main Gas Supply Line

    B. MAIN GAS SUPPLY LINE The main gas supply line is a 2” N.P.T. line, which feeds the gas required for both high and lo-fire. 1. Main Gas Valve - The main gas valve is a double solenoid gas valve containing two (2) safety shutoff valves in one (1) housing.

  • Page 38: Lo-Fire Gas Supply Line Loop

    C. LO-FIRE GAS SUPPLY LINE LOOP The lo-fire gas supply line loop is a 3/4” line, which is responsible for supplying the burner system with the gas required during lo-fire operation. 1. Adjustable Orifice - The adjustable orifice found in the lo-fire gas supply line controls the flow of gas to the burner during lo-fire.
