8 SECTION III INSTALLATION PROCEDURES Installation should be performed by competent technicians in accordance with local and state codes. In the absence of these codes, the installation must conform to applicable AMERICAN NATIONAL STANDARDS: ANSI.Z223.1-LATEST EDITION (National Fuel Gas Code) and/or ANSI/NFPA NO. 70-LATEST EDITION (National Electri[...]

9 B. LOCATION REQUIREMENTS Before installing the dryer, be sure the location conforms to local codes and ordinances. In the absence of such codes or ordinances the location must conform with the National Fuel Gas Code ANSI.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[...]

10 Dryers may be positioned side wall to side wall. However, a 1/16" minimum allowance must be made for opening and closing of the control door and the lint door. It is suggested that the dryer be positioned about two (2) feet away from the nearest obstruction for ease of installation, maintenance, and service (to be measured from the back gua[...]

11 D. FRESH AIR SUPPLY The SUPER AD-30 air supply (make-up air) must be given careful consideration to assure proper performance of each dryer. An unrestricted source of air is necessary for each dryer. As a general rule, an unrestricted air entrance from the outdoors (atmosphere) of a minimum of 1-1/2 square feet is required for each dryer. If reg[...]

12 E. EXHAUST REQUIREMENTS Exhaust duct work should be designed and installed by a qualified professional. Improperly sized duct work will create excessive back pressure which results in slow drying, increased use of energy, and shutdown of the burner by the airflow (sail) switch, burner hi-limit, or lint chamber hi-heat protector thermostat. CAUTI[...]

13 SINGLE DRYER VENTING IMPORTANT : For exhaust runs over 10 feet a minimum duct size of 10-inches must be used. H ORIZONT AL V ENTING When single 10-inch venting is used, the duct work from the dryer to the outside outlet cannot exceed 30 feet (refer to Illus. A below ). This calculation of 30 feet compensates or allows for the use of a maximum of[...]

14 If the length of the duct run or quantity of elbows used exceeds the above noted specifications, the cross section area of the duct work must be increased in proportion to the number of elbows or duct run added. IMPORTAN T: For extended duct work runs, the cross section area of the duct can only be increased to an extent. For extended duct work [...]

15 MULTIPLE DRYER (Common) VENTING H ORIZONT AL V ENTING If it is not feasible to provide separate exhaust ducts for each dryer, ducts for individual dryers may be channeled into a common main duct. Each dryer is provided with a back draft damper. The individual ducts should enter the bottom or side of the main duct at an angle not more than 45° i[...]

16 Illus. C (refer to the previous page { page 15 }) shows the minimum cross-section area for horizontal multiple dryer venting. These figures must be increased in proportion if the main duct run from the last dryer to where it exhausts has numerous elbows or is unusually long. IMPORTANT : For extended duct work runs, the cross-section area of the [...]

17 IMPORTANT VENTING REMINDERS 1. Duct work size and installation should be done by a qualified professional. 2. The dryer must be exhausted to the outdoors. 3. Duct work should be routed as short as possible to the outdoors with as few elbows as possible. 4. Avoid 90° turns ... use 30° or 45° turns instead. 5. The size of the duct work must be [...]

18 F. ELECTRICAL INFORMATION 1.

19 The electrical connections on ALL single-phase (1ø) gas and steam dryers are made into the rear service box located at the upper left area of the dryer. NOTE : On gas and steam dryers, to convert from 208 VAC to 240 VAC (or vice versa), the 24 VAC transformer wiring must be changed. 2) Electric Dryers ONLY ALL electrically heated dryers must be[...]

20 If local codes permit, power to the dryer can be made by the use of a flexible U.L. listed power cord/ pigtail (wire size must conform to rating of dryer), or the dryer can be hard wired directly to the service breaker panel. In both cases, a strain relief must be installed where the wiring enters the dryer . S I N G L E -P H A S E (1 Ø ) E L E[...]

21 5. 3-Phase (3 ø ) Wiring Connections The only electrical input connections to the dryer are the 3-phase (3ø) power leads (L1, L2, L3, and some times Neutral) and ground. Single phase (1ø) power for the control circuit is done internally to the dryer. No single-phase (1ø) input connection is required on a 3-phase (3ø) dryer. a. 3-Phase (3ø)[...]

22 CAUTION: The dryer must be grounded. A ground lug has been provided for this purpose. IMPORTANT: A separate circuit serving each dryer must be provided. The only electrical connections to the dryer are the 3-phase (3ø) leads (L1, L2, L3, and sometimes Neutral) and ground. Single-phase (1ø) power for the control circuit is done by the factory a[...]

In the absence of such codes, ALL plumbing connections, materials, and workmanship must conform to the applicable requireme[...]

25 2. Technical Gas Data a. Natural Gas The natural gas supply pressure to the dryer must be between 6 and 12 inches water column. If the pressure is too low, ignition failure and/or slow drying time may result. Excessively high supply pressure will result in erratic operation of the gas valve's internal pressure regulator. The pressure measur[...]

26[...]

27 Consistent gas pressure is essential at ALL gas connections. It is recommended that a 3/4-inch pipe gas loop be installed in the supply line serving a bank of dryers. An in-line pressure regulator must be installed in the gas supply line (header) if the (natural) gas pressure exceeds 12.0 inches of water column pressure. Refer to the illustratio[...]

28 H. STEAM INFORMATION It is your responsibility to have ALL plumbing connections made by a qualified professional to assure that the gas plumbing installation is adequate and conforms with local and state regulations or codes. Care must be exercised when leveling steam dryers into final position. After leveling the dryer, check the downward pitch[...]

29 Install an inverted bucket steam trap and check valve at least 12-inches below the steam coil as near to the coil as possible. A vacuum breaker should be installed in the piping. This will prevent the condensing steam from causing a vacuum inside the coil, and possibly damaging the coil. The supply and return lines should be insulated. This will[...]

30 3. Steam Damper Air System Connections The pneumatic (piston) damper system requires a clean, dry, regulated external supply of compressed air. The air connection is made to the system solenoid valve which is located on the rear electric service box. 2) Air Connection Air connection to system --- 1/8" N.P.T. 3) Air Regulation No air regulat[...]
