3 WARNING: DO NOT dry rags or articles coated with gasoline, kerosene, paint, wax, or grease. FIRE OR EXPLOSION COULD RESUL T . WARNING: DO NOT dry mop heads. Contamination by wax or flammable solvents will create a fire hazard. WARNING: DO NOT use heat for drying articles that contain plastic, foam, sponge rubber, or similarly textured rubberlike [...]

4 SECTION II SPECIFICA TIONS NOTE: ADC reserves the right to make changes in specifications at any time without notice or obligation.[...]

5 SECTION III INST ALLA TION 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) or ANSI/NFPA NO. 70-LATEST EDITION (National Electric[...]

6 3. The dryer must be installed with provisions for adequate combustion and make-up air supply. CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors. Every 6 months, inspect the exhaust ducting and remove any lint build up. C. DR YER ENCLOSURE REQUIREMENTS Bulkheads and partitions should be made of noncombustible mat[...]

7 D. FRESH AIR SUPPL Y REQUIREMENTS Air supply (make-up air) must be given careful consideration to assure proper performance of each dryer. An unrestricted source of air for 800 cfm (22.65 cmm) is necessary for each dryer. An unrestricted air entrance from the outdoors (atmosphere) of a minimum of 1-1/2 square feet (0.14 square meters) is required[...]

8 E. EXHAUST REQUIREMENTS Exhaust ductwork should be designed and installed by a competent technician. Improperly sized ductwork will create excessive back pressure which results in slow drying, increased use of energy, overheating of the dryer, and shutdown of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler) hi-heat[...]

9 The main duct may be any shape of cross section area, so long as the minimum cross section area is provided. Figure 1, shown above, shows the minimum cross section area for multiple dryer venting. These figures must be increased if more than twelve (12) dryers are connected to the same main (common) duct, if the main duct end run is unusually lon[...]

10 F . ELECTRICAL INFORMA TION 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 to local and state regulations or codes. In the absence of such codes, ALL electrical connections, materials,[...]

11 NOTE: Component failure due to improper voltage application will VOID THE WARRANTY . b. Electrical Service for Electric Dryers ALL electrically heated dryers must be connected to the electrical supply service shown on the dryer’s data label, which is affixed to the inside of the control door. The connecting wires must be properly sized to hand[...]

12 4. Electrical Connections for Gas Dryers A wiring diagram is located inside the front wiring box. a. Single-Phase (1ø) Dryers The electrical connections for dryers manufactured for operation at single-phase (1ø) (2-wire) are made through the top of the dryer, at the rear. The dryer is shipped with the three (3) connection leads (L1, L2 or N, a[...]

13 5. Electrical Connections for Electric Dryers The electrical input connections for each basket (tumbler) section are made at each oven contactor, located at the rear of the dryer. The only electrical connections needed are the 3-phase (3ø) leads (L1, L2, and L3) and ground. Single-phase (1ø) power for the control circuit is done by the factory[...]

14 2. Technical Gas Data * Measured at gas valve pressure tap when ignition has occurred. Measured in inches of water column (W.C.). The manifold pressure for natural gas is 3.5 inches (8.7 mb) water column. The manifold pressure for liquid propane (L.P.) is 10.5 inches (26.1 mb) water column. Drill manufacturer’s standard-equivalent (D.M.S.) to [...]

15 a. Liquid Propane (L.P.) Gas Dryers manufactured for use with liquid propane (L.P.) gas have no pressure regulator or means of regulation built into the dryer. Regulation must be provided at the gas supply (L.P. tank) or, in the case where another gas appliance of a higher required gas pressure is on the same supply line, separate regulators (ve[...]

16 IMPORTANT: Water column (W.C.) pressure of 11.0 inches (27.4 mb) is required at the gas valve pressure tap of each dryer for proper and safe operation. This will result in a manifold pressure of 10.5 inches (26.1 mb) water column. The 11.0 inch (27.4 mb) water column pressure should be obtained when the gas valve is firing in its high-fire stage[...]

17 I. PREOPERATIONAL TESTS ALL dryers are thoroughly tested and inspected before leaving the factory. However, a preoperational test should be taken before the dryer is publicly used. It is possible that adjustments have changed in transit. 1. Turn on electric power to dryer. Open ALL gas shutoff valves. 2. Put the proper number of coins into the c[...]
