  • Page 18: Dryer Enclosure Requirements

    C. DRYER ENCLOSURE REQUIREMENTS Even though a 12-inch (30.48 cm) clearance is acceptable, it is recommended that the rear of the dryer be positioned approximately 2 feet (0.60 meters) from the nearest obstruction (i.e., wall) for ease of installation, maintenance, and service. Bulkheads and partitions should be made from noncombustible materials. The clearance between the bulkhead header and the dryer must be a minimum of 4-inches (10.16 cm) and must not extend more than 4-inches (10.16 cm) to the rear of the dryer front.

  • Page 19: Fresh Air Supply Requirements

    D. 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 drying efficiency will be adversely affected.

  • Page 20: Exhaust Requirements

    IMPORTANT: Make-up air must be provided from a source free of dry cleaning solvent fumes. Make-up air that is contaminated by dry cleaning solvent fumes will result in irreparable damage to the motors and other dryer components. NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY. E.
  • Page 21 ALL ductwork should be smooth inside with no projections from sheet metal screws or other obstructions, which will collect lint. When adding ducts, the ducts to be added should overlap the duct to which it is connected. ALL ductwork joints must be taped to prevent moisture and lint from escaping into the building. Additionally, inspection doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning of lint from the ductwork.
  • Page 22 2. Single Dryer Venting Where possible, it is suggested to provide a separate exhaust duct for each dryer. The exhaust duct should be laid out in such a way that the ductwork travels as directly as possible to the outdoors with as few turns as possible.
  • Page 23 IMPORTANT: For extended ductwork runs, the cross section area of the duct can only be increased to an extent. Maximum proportional ductwork runs cannot exceed 20 feet (6.09 meters) more than the original limitations of 20 feet (6.09 meters) with two (2) elbows. When the ductwork approaches the maximum limits as noted in this manual, a professional heating, venting, and air conditioning (HVAC) firm should be consulted for proper venting information.
  • Page 24 The main duct may be any shape or cross-sectional area, so long as the minimum cross section area is p r o v i d e d . T h e illustrations on page 21 show the minimum cross section area for multiple dryer round or square venting.

    H. STEAM INFORMATION It is your responsibility to have ALL steam plumbing connections made by a qualified professional to assure that the installation is adequate and conforms to local and state regulations or codes. IMPORTANT: Failure to comply with the requirements stipulated in this manual can result in component failure, which will VOID THE WARRANTY.
  • Page 37 a. The pressure of the condensate in the steam supply will cause water hammer and subsequent heat exchanger (steam coil) failure. The steam supply connection into the main supply line must be made within a minimum 12-inch (30.48 cm) riser. This will prevent any condensate from draining towards the dryer.
  • Page 38 4. Steam Damper Air System Connections The steam dryer is manufactured with a pneumatic (piston) damper system, which requires an external supply of compressed air. The air connection is made to the steam damper solenoid valve, which is located at the rear inner top area of the dryer just above the electric service relay box (refer to the bottom illustration on page 35).
  • Page 39 6. Steam Damper Air Piston (Flow Control) Operation Adjustment System Although the damper operation was tested and adjusted prior to shipping at 80 PSI (5.51 bars), steam damper operation must be checked before the dryer is put into operation. Refer to page 34 for instructions to check steam damper system operation.

  • Page 40: Preparation For Operation

    I. PREPARATION FOR OPERATION The following items should be checked before attempting to operate the dryer: 1. Read ALL “CAUTION,” “WARNING,” and “DIRECTION” labels attached to the dryer. 2. Check incoming supply voltage to be sure that it is the same as indicated on the dryer data label located on the left side panel/wall area behind the control door as shown on page 9.

  • Page 41: Preoperational Tests

    J. 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 42 c. Steam Models 1) Check to insure that steam damper is functioning properly. a) The steam damper should not “slam” (open/closed) when it reaches the end of (piston) travel. Additionally, the steam damper should not bind or stop during travel. If either of these conditions occur, the flow control must be adjusted.

  • Page 48: 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 49 STEAM DRYERS Clean the steam coil fins. We suggest using compressed air and a vacuum cleaner with brush attachment. WARNING: When cleaning steam coil fins, be careful not to bend the fins. If fins are bent, straighten by using a fin comb, which is available from local air conditioning supply houses. 90 DAYS Remove lint from around basket (tumbler), drive motors, and surrounding areas.

  • Page 50: Adjustments

    B. ADJUSTMENTS 7 DAYS AFTER INSTALLATION AND EVERY 6 MONTHS THEREAFTER Inspect bolts, nuts, screws (bearing setscrews), and nonpermanent gas connections (unions, shutoff valves, orifices, and grounding connections). Motor and drive belts should be examined. Cracked or seriously frayed belts should be replaced. Tighten loose V-belts when necessary. Complete operational check of controls and valves.
