WARNING: DO NOT dry mop heads. Contamination by wax or flammable solvent will create a fire hazard. WARNING: DO NOT use heat for drying articles that contain plastic, foam, sponge rubber, or similarly textured rubberlike materials. Drying in a heated basket (tumbler) may damage plastics or rubber and also may be a fire hazard. 7. A program should be established for the inspection and cleaning of lint in the burner area, exhaust duct work, and area around the back of the dryer. The frequency

SECTION II 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. Maximum operating efficiency is dependent upon proper air circulation. The accumulation of lint can restrict this air flow. If the guidelines in this section are met, an ADC dryer will prov

WARNING: TO AVOID THE HAZARD OF ELECTRICAL SHOCK, DISCONTINUE ELECTRICAL SUPPLY TO THE DRYER. MONTHLY Empty the compressed air filter bowl. Clean any lint accumulation from the gas valve/burner area at the top of the dryer, the fan (impellor) motor, and the fan (impellor) bearings located in the dryer base. EVERY 6 MONTHS STEAM MODELS - clean the steam coil fins. We suggest using compressed air and a vacuum cleaner with brush attachment. NOTE: When cleaning steam coil fins, be careful not to b

SECTION V COMPONENT DESCRIPTION A. Heat Section The AD-200 dryer uses three (3) types of heat sources: natural gas, liquid propane (L.P.) gas, and steam. Natural gas and L.P. gas are not directly replaceable. The gas valves need to be modified to use other than the type of heat specified on the nameplate. 1. ADG-200 (gas) dryers utilizes a Direct Spark Ignition (DSI) module to monitor that a flame is established. If for some reason the flame signal is lost, the DSI module will shut off the ga

a. The Direct Spark Ignition (DSI) Module is a 24 VAC device designed to be the "controller" of the DSI system. When activated by the dryer controls, this module constantly monitors and controls the functions of the DSI system (i.e., spark activation, gas valve off/on, flame verification, etc.). Additionally, the DSI Module has self diagnostic capabilities. 24 VAC Direct Spark Ignition (DSI) Module b. The Ignitor and Flame-Probe Assembly is located in the burner flame area and is used to ignite

e. The Tumbler Hi-Limit Switch is a thermostat type switch located above the Lint Basket. Its function is to discontinue heat (flame) in the event of an over temperature situation (above 225º F). MAN3484 225º F Thermostat f. The gas valve used in the ADG-200 is of the redundant type which means that the gas valve is actually two gas valves in one; one in series with the other. This is a safety feature which provides protection against gas flow in the event that one of the valves does not s
