12 4) Disconnect the two (2) pin connector from the Phase 6 Microprocessor Controller (computer). Refer to the wiring diagram on the Control Door . 5) Disconnect the ground (GND) wire from the Phase 6 Microprocessor Controller (computer). NOTE: b 2 and b 3 apply only to models manufactured after August 1997.
13 C . D R YER ENCLOSURE REQUIREMENTS Even though a 12-inch (30.48 cm) clearance is acceptable, it is recommended that the rear of the dryer be positioned approximately two (2) feet (24-inches) - 0.61 meters (60.96 cm) - from the nearest obstruction (i.
14 D . F R E S H AIR SUPPL Y REQUIREMENTS When the dryer is operating, it draws in room air, heats it, passes this air through the tumbler (basket), and exhausts it out of the building. Therefore, the room air must be continually replenished from the outdoors.
15 E. EXHAUST REQUIREMENTS 1. General Exhaust Duct W ork Information Exhaust duct work should be designed and installed by a qualified professional. Improperly sized duct work will create excessive ba.
16 a . Outside Duct W ork Protection 1) T o protect the outside end of horizontal duct work from the weather , a 90° elbow bent downward should be installed where the exhaust exits the building. If the duct work travels vertically up through the roof, it should be protected from the weather by using a 180° turn to point the opening downward.
17 It is suggested that the duct work from each dryer (minimum of 12-inches [30.48 cm] for a single dryer) not exceed 15 feet (4.57 meters) with no more than three (3) elbows (including dryer connection).
18 NOTE: Where the exhaust duct passes through a wall, ceiling, or roof made of combustible materials, the opening must be 2-inches (5.08 cm) larger (all the way around) than the duct.
19 The duct work should be smooth inside with no projections from sheet metal screws or other obstructions which will collect lint. When adding ducts, the duct to be added should overlap the duct to which it is to be connected. ALL duct work joints must be taped to prevent moisture and lint from escaping into the building.
20 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 with local and state regulations or codes.
21 2. Electrical Service Specifications IMPOR T ANT : The dryer must be connected to the electric supply shown on the data label that is affixed to the left wall, behind the upper control door area (refer to the illustration o n page 9 ).
22 3. Electrical Connections NOTE : A wire diagram is located in the front electrical control box for connection data. The only electrical input connections to the dryer are the 3-phase (3ø) power leads (L1, L2, and L3), GROUND, and in the case of 4 wire service, the NEUTRAL.
23 4. Grounding Grounding (earth) connections 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 Electrical Code ANSI/NFP A NO. 70-LA TEST EDITION, or in Canada, the Canadian Electrical Codes Parts 1 & 2 CSA C22.

25 2) Liquid Propane (L.P .) Gas Dryers made for use with L.P . gas have the gas valve s internal pressure regulator blocked open so that the gas pressure must be regulated upstream of the dryer . The pressure measured at each gas valve pressure tap must be a consistent 10.
26 IMPOR T ANT : T est ALL connections for leaks by brushing on a soapy water solution (liquid detergent works well). W ARNING: NEVER TEST FOR LEAKS WITH A FLAME!!! ALL components/materials must conform to National Gas Code Specifications ANSI Z223.1-LA TEST EDITION, or in Canada, the Canadian Installation Codes CAN/CGA-B149.
27 H. PREP ARA TION FOR OPERA TION/ST AR T -UP The following items should be checked before attempting to operate the dryer: 1. Read ALL CAUTION , W ARNING , and DIRECTION labels attached to the dryer .
28 IMPOR T ANT : Dryer blower motor impellor/fan as viewed from the front must turn in the clockwise (CW) direction, otherwise the dryer efficiency will be drastically reduced and premature component failure can result. 5. Heat Circuit Operational T est a .
29 2) Spin and stop times are adjustable in the Manual (timed) Mode. b. Dual T imer Dryer Models 1) Both spin time and stop (dwell) time are adjustable (refer to page 36 ).
30 NOTE: Pressing keyboard (touchpad) key A, B, C, D, and F will also start the dryer . The six (6) preprogrammed drying cycles (A through F) have been stored in the microprocessor controller (computer) memory .
31 SECTION IV SER VICE/P AR TS INFORMA TION A. SER VICE 1. Service must be performed by a qualified trained technician, service agency , or gas supplier .
32 SECTION V W ARRANTY INFORMA TION A. RETURNING W ARRANTY CARD(S) 1. Before any dryer leaves the ADC factory test area, a warranty card is placed on the back side of the main door glass.
33 2. Each part must be tagged with the following information: a. Model number and serial number of the dryer from which part was removed. b. Nature of failure (be specific). c . Date of dryer installation. d. Date of part failure. e . Specify whether the part(s) being returned is for a replacement, a credit, or a refund.
34 SECTION VI ROUTINE MAINTENANCE A. CLEANING A program and/or schedule should be established for periodic inspection, cleaning, and removal of lint from various areas of the dryer , as well as throughout t he duct work system. The frequency of cleaning can best be determined from experience at each location.
35 Remove lint accumulation from inside the control box and at rear area behind the control box. Impellor (fan/blower) shaft bearings should be lubricated using Shell Alvania grease NLGI 2 or its equivalent. Generically , this grease would be described as an NLGI grade 2 multipurpose industrial grease with a lithium thickener and mineral base oil.
36 SECTION VII REVERSING TIMER SPIN/DWELL ADJUSTMENTS T imer models have an electronic reversing timer in the electrical service box which is located in the upper left rear area of the dryer .
