Page 14: Unpacking/Setting Up
B. UNPACKING/SETTING UP Remove protective shipping material (i.e., plastic wrap, and/or optional shipping box) from dryer. IMPORTANT: Dryer must be transported and handled in an upright position at all times. The dryer can be moved to its final location while still attached to the skid or with the skid removed.
Page 15 1. LEVELING DRYER a. To level dryer, place 4-inch square metal shims (refer to illustration above) or other suitable material under the base pads. It is suggested that the dryer be tilted slightly to the rear. 2. If more headroom is needed when moving dryer into position, the top console (module) may be removed.
Page 16: Dryer Enclosure Requirements
C. DRYER ENCLOSURE REQUIREMENTS Even though a 12-inch clearance is acceptable, it is recommended that the rear of the dryer be positioned approximately two (2) feet (24-inches) from the nearest obstruction (i.e., wall) for ease of installation, mainte- nance, 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 and must not extend more than 4- inches to the rear of the dryer front.
Page 17: Fresh Air Supply
D. FRESH AIR SUPPLY 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 18: 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 motors and other dryer components. NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY. E.
Page 19 ALL duct work 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 con- nected. ALL duct work 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 duct work for periodic inspection and clean-out of lint from the duct work.
Page 20 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 duct work travels as directly as possible to the outdoors with as few turns as possible.
Page 21 (minimum for gas dryers or 72 Kw electric dryers) or 16-inch (minimum for steam dryers or 80 Kw electric dryers) duct is added. IMPORTANT: The AD-120ES is not provided with a back draft damper. When exhausted into a multiple (common) exhaust line, a back draft damper must be installed at each dryer duct.
Page 22 The main duct may be any shape or cross sectional area, so long as the minimum cross section area is provided. The illustrations on page 19 and page 20 show the minimum cross section area for multiple dryer round or square venting.
