  • Page 22: External Supply Connections

    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.
  • Page 23 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. The maximum operating steam supply pressure is 150 psig (10.34 bar). The presence of condensate in the steam supply will cause water hammer and subsequent steam coil (battery) failure.
  • Page 24 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.
  • Page 25 The duct work must be smooth on the inside with no projections from sheet metal screws or other obstructions which would collect lint. Inspection doors must be installed at strategic points in the duct work for periodic lint removal. Use smooth sweeping elbows instead of sharp 90º elbows. The radius of an elbow should be at least 1-1/2 times the duct diameter.

  • Page 26: Electrical Requirements

    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. In the absence of such codes, ALL electric connections, materials and workmanship must confirm to the applicable requirements of the National Electrical Code ANSI/NFPA NO.
  • Page 27 2. Electrical Service Specifications ADS-464 (Steam) LECTRICAL IMPORTANT: 208 VAC and 230/240 VAC ARE NOT THE SAME. When ordering, specify exact voltage. A. Fuse ratings are dual-element, time-delay, current limiting, class RK1 or RK5 ONLY. NOTES: B. Circuit breakers are thermal magnetic (industrial) type ONLY. For others, calculate/verify correct breaker size according to appliance amp draw rating and type of breaker used.
  • Page 28 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. One is 3-phase (3ø) electric service that feeds the dryer itself, and the other is single-phase (1ø) electric service that feeds the safety sprinkler system.

  • Page 29: Fresh Air Supply Requirements

    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. Therefore, the room air must be continually replenished from the outdoors. If makeup air is inadequate, drying time and efficiency will be adversely affected, and safety will be compromised.

  • Page 30: Steam Information

    IMPORTANT: Failure to comply with the requirements stipulated in this manual can result in component failure which will VOID THE WARRANTY. NOTE: The ADS-464 is manufactured with a pneumatic (piston) damper system which requires an external supply of air (80 psi ± 10 psi).

  • Page 31: Shut Down Instructions

    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. This will prevent the condensing steam from causing a vacuum inside the coil and possibly damaging the coil.

  • Page 32: 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. 3.

  • Page 33: 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. Maximum operating efficiency is dependent upon proper air circulation.

  • Page 39 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. Then, the damper piston is actuated, opening the dampers recirculating fifteen percent (15%) of the exhaust air back over the gas burner and into the tumbler (basket).

  • Page 40: Compressed Air System

    NOTE: Current Production models use a Filter Regulator Assembly while Past Production models used a Filter/Regulator/Lubricator (FRL) Assembly. (Refer to the illustrations below.) The compressed air system of the ADS-464 dryer consists of a number of pneumatic pistons located throughout the dryer, a Filter Regulator assembly, and pneumatic control panel.
  • Page 41 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.
  • Page 42 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. When 120 volts is supplied to the “S5” side of the front tilting piston solenoid valve coil, the round internal spool in the core of the solenoid will move, allowing 80 PSI air to flow into the bottom ports of the front tilting pistons, while the top ports of these pistons are bled to the atmosphere.
