11 D. FRESH AIR SUPPL Y REQUIREMENTS The D-40 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 (0.14 square meters) is req[...]

12 E. EXHAUST REQUIREMENTS Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork 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-limits, or lint chamber hi-limit protector thermostat. The d[...]

13 SINGLE DR YER VENTING IMPORTANT: For exhaust duct runs over 20 feet (6.1 meters) a minimum size of 10-inches (25.4 cm) must be used. HORIZONT AL VENTING When a single 8-inch (20.32 cm) horizontal vent is used, the ductwork to the outlet cannot exceed 20 feet (6.1 meters), refer to Illus. A below . This calculation of 20 feet (6.1 meters) compens[...]

14 VER TICAL VENTING When vertical single 10-inch (25.4 cm) venting is used (refer to Illus. B below ), the ductwork from the dryer to the outside outlet cannot exceed 40 feet (12.19 meters). This calculation compensates for the use of a maximum of three (3) elbows including the two (2) elbows creating the 180° (turned downward) outside outlet. Il[...]

15 MUL TIPLE DR YER (COMMON) VENTING 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° in the direction of t[...]

36 NOTES: 1. If the Anti-Wrinkle program is active, the light emitting diode (L.E.D.) display will continue to read “donE,” and the microprocessor controller (computer) will proceed through the Anti-Wrinkle program until the maximum “Active Guard Time” has expired or until the door i s opened, whichever comes first. The L.E.D. display will [...]

37 IMPORTANT: If the door is opened during a cycle, both the heat and motor will stop. However, the microprocessor controller (computer) will continue to count the time, either upward or downward, depending on which parameter is programmed. Continuation of the cycle will resume only after the door has been closed and any other of the three (3) temp[...]

38 NOTE: Pressing keyboard (touch pad) key “A”, “B”, “C”, “D”, and “F” will also start the dryer.
