9 2. Reassembly Instructions For Dryers Shipped In Three (3) Pieces When the dryer is shipped in three (3) pieces, the tumbler and the tumbler base sections are shipped as two (2) separate pieces. The heat console section is shipped as the third piece.
10 c. Reassemble The Tumbler (Basket) Section To The Tumbler (Basket) Base Lift the tumbler (basket) section with a cable through the eye bolts on top of the section.
11 B. LOCATION REQUIREMENTS The model ADS-464 dryer requires 36-inches of space on each side of the dryer and 36-inches of space behind the unit for ease of maintenance and tilting. The dryer must be leveled for proper operation. If shimming is required, put 9-1/2” x 9-1/2” metal shims under the base feet.
12 b. Rear Tilt Piston Lines This connection is made at the rear of the dryer in the space between the lower heat console section and the tumbler (basket) base section. Insert the 3/8” poly-flo tube coming from the tumbler (basket) base section to the 3/8” brass fitting marked with the corresponding number.
13 c. Load Door Piston Air Lines and Cool Down Damper Piston Air Lines The load door cylinder pneumatic connections are made in the lower heat console section, in the area behind the pneumatic panel. To connect the 1/4” poly-flo lines into the corresponding needle valves, match the number on the line with the number on the needle valve.
14 2. Electric a. Tumbler (Basket) Motors The disconnects for the two (2) tumbler (basket) motors are located in the lower heat console. The right drum (tumbler/basket) motor disconnect is located in the lower heat console on the upper shelf towards the left.
15 c. Annunciator, Pendent, Over-Burner, and RTD (Resistive Temperature Device) Cable Remove the four (4) bolts that hold on the character (464) panel. Open the door to the main electrical enclosure, the female end of the RTD (Resistance Temperature Device) cable will be found there.
16 d. Pendent On the top of the heat console section of the dryer near the pendent, there is a junction box with four (4) cables coming out of it. Two (2) of the cables from the junction box have connectors on the end, a 5-pin connector and an 11-pin connector.
17 e. Tumbler Junction Box Disconnect Remove the four (4) bolts that hold on the lower left side panel, then remove the panel. The safety panel is next to be removed. This is done by removing the six (6) bolts on the bottom of the safety panel where the tumbler section and the base meet.
18 D. EXTERNAL SUPPLY CONNECTIONS 1. Sprinkler Water Supply A 40 PSI supply of water must be connected into the 1” N.P.T. sprinkler connection located on the left side of the tumbler base. 2. Compressed Air Supply A minimum of 20 cubic feet per hour (cfh) at 80 PSI of dry, clean, and regulated compressed air must be supplied to the dryer.
19 3. Steam Supply and Condensate Return Connections The steam supply into the dryer is made into the 2-1/2” F.T.P. pipe fitting located on top of the heat module console.
20 4. Exhaust Ducting The dryer’s exhaust air must be vented to the outdoors by the shortest route possible with the number of elbows kept to a minimum. The duct should be designed and installed by qualified technicians. Improperly designed duct work may reduce the airflow through the dryer, causing improper and unsafe drying conditions.
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 230/240 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 ADS-464 dryer, this section is located at the bottom left of the main electrical enclosure. The ADS-464 dryer, with sprinkler option, 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 G. STEAM INFORMATION It is your responsibility to have ALL plumbing connections made by a qualified professional to assure that the steam plumbing installation is adequate and conforms with local and state regulations or codes.
27 c. Flexible hoses or couplings must be used. The dryer vibrates slightly when it runs and this will cause the steam coil connections to crack if they are hard piped to the supply and return mains. e. A 3/4” vacuum breaker should be installed for each unit in the piping.
28 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.
29 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.
30 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.
31 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.
32 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).
33 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.
34 B. MAIN AIR BLOWER and HEAT RECLAIMER SYSTEM The fan which moves the exhaust air through the ADS-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.
35 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.
36 C. COMPRESSED AIR SYSTEM NOTE : Current Production models use a Filter Regulator Assembly while Past Production models used a Filter/Regulator/Lubricator (FRL) Assembly.
37 3. Pneumatic Control Panel The pneumatic control panel of a 2-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.
38 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.
39 D. SAFETY DEVICES The ADS-464 dryer is equipped with numerous safety devices to ensure that the dryer operates safely. The chart on the following page ( page 40 ) lists each device with it’s location, function, computer display message, and result of tripping.
