V 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.
NM 2. The dryer must not be installed or stored in an area where it will be exposed to water and/or weather . 3. The dryer is for use in noncombustible locations. 4. Provisions for adequate air supply must be provided as noted in this manual (refer to Fresh Air Supply in Section D ).
NN C. DR YER ENCLOSURE REQUIREMENTS Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of 12-inches (30.
NO IMPOR T ANT : Make-up air openings should not be located near duct work exhaust outlets. If make-up air opening(s) are too close to the exhaust outlet, lint and fumes may be drawn back into the dryer area through these openings. NOTE: Component failure due to dry cleaning solvent fumes will VOID THE W ARRANTY .
NP 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, .
NQ NOTE: When the exhaust duct work passes through a wall, ceiling, or roof made of combustible materials, the opening must be 2-inches (5.08 cm) larger than the duct ( ALL the way around).
NR 2. Multiple Dryer (common) V enting 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 45º in the direction of the airflow .
NS IMPOR T ANT : DO NOT use screens or caps on the outside opening of the exhaust duct work..
NT 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.
NU 2. Grounding A ground (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.
NV Providing local codes permit, power to the dryer can be made by use of a flexible U.L. listed power cord/pigtail (wire size must conform to the rating of the 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 .

OP 3. Piping Connections ALL components/materials must conform to National Fuel Gas Code Specifications ANSI Z223.1-LA TEST EDITION, or in Canada, CAN/CGA-B149.
OQ W ARNING: NEVER TEST FOR LEAKS WITH A FLAME!!! IMPOR T ANT : The dryer and its individual shutof f valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of 1/2 psig (3.5 kPa).
OR H. PREP ARA TION FOR OPERA TION 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 .
OS 4) Open main door to stop the dryer , and change selection to “PERM PRESS” (medium) setting. Repeat this procedure, but change the selection (setting) to “HI” (high). This will confirm that setting key circuits and door switch circuits are functioning properly .
OT 4. Make a complete operational check of ALL safety-related circuits (i.e., door switches, hi-limit thermostats, sail switches, basket [tumbler] safety thermostats, etc.). NOTE: The sail switch can be checked for proper operation by opening the control door while the dryer is running and the heating unit (burner) active (on).
OU SECTION IV OPERA TING INSTRUCTIONS A. ST AR TING THE DR YER The dryer is available for use when the appropriate microprocessor controller (computer) light emitting diode (L.E.D.) display reads “FILL” and/or the amount needed to start the dryer (i.
OV NOTE: When a cycle is interrupted by opening the main door , the cycle time will continue to count downward, regardless if the door is open or closed until a keyboard (touch pad) selection is made. 2) Selection (setting) changes can be made at any time during the drying cycle by opening and closing the main door and then making a new selection.
PM SECTION V SER VICE/P AR TS INFORMA TION A. SER VICE 1. Only properly licensed or trained technicians should service the dryer . If service is required, contact the reseller from whom the ADC equipment was purchased. If the reseller cannot be contacted or is unknown, contact the ADC Service Department for a reseller in your area.
PN SECTION VI 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.
PO a. The R.M.A. issued by the factory , as well as any other correspondence pertaining to the returned part(s), must be included inside the package with the failed merchandise. 2. Each part must be tagged with the following information: a. Model number and serial number of the dryer from which part was removed.
PP SECTION VII 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 the duct work system. The frequency of cleaning can best be determined from experience at each location.
PQ 90 DA YS Remove lint from the motor air vents and surrounding area. IMPOR T ANT : Lint accumulation will restrict the airflow over the motor(s), causing overheating and irreparable motor damage. Motor failure due to lint accumulation will VOID THE W ARRANTY .
PR B. ADJUSTMENTS 7 DA YS AFTER INST ALLA TION and EVERY 6 MONTHS THEREAFTER Inspect bolts, nuts, screws (bearing set screws), nonpermanent gas connections (unions, shutoff valves, orifices, etc.), electrical terminations, and grounding connections. Motor and drive belts should be examined.
