INSTALLATION PROCEDURES SECTION 3 INSTALLATION PROCEDURES Installation should be performed by competent technicians in accordance with local and state codes. In the absence of these codes, installation must conform to applicable AMERICAN NATIONAL STANDARDS: ANSI Z223.1 -LA TEST EDITION (NA TIONAL FUEL CODE) or ANSI/NFPA No.70 LATEST EDITION (NATIONAL ELECTRIC CODE or in CANADA, the installation must conform to applicable CANADIAN STANDARDS: CAN/CGA-B149.1-M91 (Natural Gas) or CAN/CGA-BI49.2-M91 (L.P.
INSTALLATION PROCEDURES B. 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 nearest obstruction (i.e., wall) for ease of installation, maintenance, and service. Bulkheads and partitions should be made from noncombustible materials.
INSTALLATION PROCEDURES C. 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. Ignition problems and sail switch "fluttering" problems may result, as well as premature motor failure from overheating.
INSTALLATION PROCEDURES 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 VOIDS THE WARRANTY. D. EXHAUST REQUIREMENTS 1. General Exhaust Duct Work Information Exhaust duct work should be designed and installed by a competent technician.
INSTALLATION PROCEDURES IMPORTANT: DO NOT use screens or caps on the outside of opening of exhaust duct work. Figure.3-3 Outside Duct Work Protection 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. It is suggested that the use of 90° turns in ducting be avoided; use 30° and/ or 45° angles instead.
INSTALLATION PROCEDURES Figure.3-4 Single Dryer Venting IMPORTANT: For extended duct work runs, the cross section area of the duct work can only be increased to an extent. Maximum proportional duct work runs cannot exceed twenty (20) feet more than the original limitations of twenty (20) feet with two (2) elbows. When the duct work approaches the maximum limits as noted in this manual, a professional heating venting air conditioning (HV AC) firm should be consulted for proper venting information.
INSTALLATION PROCEDURES 3. Multiple Dryer (Common) Venting If it is not feasible to provide separate exhaust ducts for each dryer, ducts from individual dryers may be channeled into a "common main duct." The individual ducts should enter the bottom or side of the main duct at an angle not more than 45° in the direction of air flow and should be spaced at least 48-3/8 inches apart.
INSTALLATION PROCEDURES Figure.3-5 Multiple exhaust connection.
INSTALLATION PROCEDURES Figure.3-6 Multiple exhaust connection.
INSTALLATION PROCEDURES Figure.3-7 Multiple exhaust connection. CAUTION: Improperly sized or installed exhaust duct work can create a potential fire hazard. Where possible, it is desirable to provide a separate exhaust air duct for each dryer. The duct should go as directly as possible to the outside air. Avoid sharp 90o right-angle turns in the ducting; use 30o or 45o angles, instead. The radius of the elbows should preferably be 1-1/2 times the diameter of the duct.
INSTALLATION PROCEDURES more than 45o. The main duct should be tapered with the diameter increasing before each individual duct is added. Inadequate exhaust facilities may cause high temperature limit switches or airflow switches to shut off the dryers. Do not disable the switches, which are provided for your safety. Instead, investigate the exhaust ducting.
INSTALLATION PROCEDURES WARNING: 208 VAC and 230/240 VOLTS ARE NOT THE SAME. Any damage done to dryer components due to improper voltage connection will automatically VOID THE WARRANTY. 3. Grounding A ground (earth) connection must be provided and installed in accordance with state and local codes. In the absence of these codes, grounding must conform to applicable requirements of the NATIONAL ELECTRIC CODE (ANSI/NFPA NO.70-1984).
INSTALLATION PROCEDURES Providing local codes permit, power to the dryer can be made by the use of a flexible U.L. listed cord/pigtail (wire size must conform to the rating of the dryer), or the dryer can be hard wired directly to the service breaker. In all cases, a strain relief should be used both where the wiring enters the dryer and the service box. Power connector (R, S, T) Figure.3-9 Electric Power Connector. F.
INSTALLATION PROCEDURES 1. Gas Supply The gas dryer installation must meet the American National Standard: National Fuel Gas Code Z223.1 – LATEST EDITION, or in Canada, the Canadian Installation Codes CAN/CGA – B149.1 – M91 (Natural Gas) or CAN/CGA – B149.2 – M91 (L.P.
