21 IMPORTANT : DO NOT use screen or caps on the outside opening of the exhaust duct work. Screens will clog with lint and caps will restrict the exhaust airflow. The duct work must be smooth on the inside with no projections from sheet metal screws or other obstructions which would collect lint.
22 E. ELECTRICAL REQUIREMENTS 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 with local and state regulations or codes.
23 2. Electrical Service Specifications IMPORTANT : The dryer must be connected to the electric supply shown on the data label that is affixed to the right side of the main electrical enclosure. In the case of 208 VAC or 240 VAC, the supply voltage must match the electric service specifications of the data label exactly .
24 3. Electrical Service The electrical power is connected the dryer at the high voltage section of the control cabinet. On the ADG-464 dryer, this section is located at the bottom left of the main electrical enclosure. The ADG-464 dryer must be supplied with two (2) independent input power lines.
25 F. FRESH AIR SUPPLY REQUIREMENTS When the dryer is operating, it draws in room air, heats this air through the tumbler (basket), and exhausts it out of the building.
26 SECTION IV PRE START-UP A. PREPARATION FOR OPERATION 1. The supply voltage must match the dryer voltage as stated on the aluminum dryer data label which is located on the inner right wall of the electrical cabinet. 2. A separate fused power supply must be connected into safety sprinkler circuit power connection.
27 SECTION V ROUTINE MAINTENANCE A. CLEANING A program or schedule should be established for periodic inspection, cleaning, and removal of lint from various areas of the dryer, as well as throughout the duct work system. The frequency of this cleaning can best be determined from experience at each location.
28 MONTHLY Grease the four (4) tumbler shaft pillow bearings with DC-44 ( Dow Corning ) grease or equivalent . DC-44 is a lithium grease that conforms to NLGI Grade 2 and has a temperature range of 40º F (4.4º C) to 400º F (204.4º C). Empty the compressed air filter bowl and add oil to the compressed air lubricator bowl.
29 SECTION VI COMPONENT SYSTEM DESCRIPTIONS A. TUMBLER (BASKET) SUPPORT and DRIVE SYSTEM IMPORTANT : Always keep the tumbler (basket) section of the dryer in an upright position when moving it.
30 3. Tumbler and Basket Drive System There are two (2) 5 HP tumbler drive motors. Each motor drives one of the 2-inch diameter tumbler drive shafts, and the motors spin simultaneously so that all four (4) sets drive wheels work together to spin the tumbler (basket).
31 1) Front Panel Electrical Connections: a) Front Position Switch Disconnect Plug; The front door position switch disconnect plug is located on the left side of the front doors. Disconnect this plug and feed the cable through the right hand side of the tumbler section.
32 B. MAIN AIR BLOWER and HEAT RECLAIMER SYSTEM The fan which moves the exhaust air through the ADG-464 dryer is a 22-inch diameter, squirrel cage wheel that is driven at 1,100 rpm by a 25 HP motor. This fan moves a maximum of 13,000 cfm (368 cmm) air through the dryer.
33 The dryer is equipped with a pneumatically operated heat reclaimer damper, which when opened, will recirculate approximately fifteen percent (15%) of the dryer’s exhaust air. The heat reclaimer damper is closed until ignition of flame has been established.
34 C. COMPRESSED AIR SYSTEM The compressed air system of the ADG-464 dryer consists of a number of pneumatic pistons located throughout the dryer, an FRL (Filter/Regulator/Lubricator) assembly, and pneumatic control panel. 1. Air Pistons: The pistons are actuated by solenoid and flow control valves that are under computer control.
35 3. Pneumatic Control Panel The pneumatic control panel of a two-way tilt dryer has two (2) tilting solenoid valves, one to control the front set of tilting pistons and a second to control the rear set of tilting pistons. A 1-Way Tilt dryer has only one (1) tilting solenoid valve.
36 4. Internal and External Pilot Air Supply On two-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.
37 D. GAS BURNER and IGNITION SYSTEM The ADG-464 dryer gas burner system operates an on/off gas rate sequences to accurately control the tumbler’s (basket’s) drying temperature.
38 1. Major Burner Components a. Burner Controller Module (BCM) The BCM (burner controller module) provides effective burner flame safeguard control through adjust able purge and trial-for-ignition timing.
39 2) L.E.D. (light emitting diode) and Neon Displays of the BCM (Burner Controller Module) a) Operating Interlock - L.E.D. (light emitting diode) is lit when: ALL safety interlock switches are closed applying a 120 VAC signal to terminal #7 of the burner controller module (BCM).
40 h) Burner Fan Air Switch Status Indicator - Neon is not lit; • Air switch is not closed after start-up of burner fan. • Door interlocks are open.
41 a) Burner Fan Air Switch The differential in air pressure is measured by the burner fan air switch, which is located next to the burner fan motor. If the combustion air is inadequate, this switch will prevent ignition. The setting of this switch is adjustable, and it should be set at 12 to 15 millimeters (.
42 d) Combustion Air Damper To produce the required combustion airflow, this damper can be adjusted. Remove the screen to get access to the damper. Moving the damper closer to the blower inlet opening will reduce the combustion airflow, and moving it away from the blower inlet opening will increase the airflow.
43 Top Motorized Gas Valve The valve sets the gas rate of 2,800,000 btu/hr (705,588 kcal/hr). To achieve this rate, the has pressure must be set for 2.5-inches water column (W.C.) - 6.22 mbar - for natural gas and 1.25 inch water column (W.C.) - .3.1 mbars - for L.
44 If ALL safety switches are closed, the burner controller module (BCM) will start the burner fan motor (BCM terminal #8). The BCM (burner controller module) waits 10-seconds to allow the blower motor to get up to speed, and then checks that the burner fan combustion air switch (BCM terminal #6) circuit is closed.
45 Once the flame probe signal is detected by the burner controller module (BCM), it waits 5-seconds to allow the pilot to stabilize and then opens the main motorized gas valves (BCM terminal #5) in sequence.
46 E. SAFETY DEVICES The ADG-464 dryer is equipped with numerous safety devices to ensure the dryer operates safely. The chart on the following page ( page 47 ) lists each device with its location, function, computer display message, and result of tripping.
