The serial number can be found on the machine data plate. Model AM14T Model AM14TC Model AM14F with Booster Heater shown Fig. 1 – 4 – DO NOT attempt to operate this dishwasher in the chemical sanitizing mode without a properly installed, NSF-listed, chemical sanitizer feeder (not supplied with machine). Contact an authorized detergent representative for information about a chemical sanitizer feeder. The pump motor is rated 2HP and has thermal overload protection. The fill line incorporates an atmospheric vacuum breaker to prevent any reverse flow of water from the dishwasher into the potable water supply. A float, located in the wash tank, will shut off the heat supply if the water level becomes too low. When the water returns to a proper level, the heating circuit is again operational. A frame-mounted 13KW electric booster water heater is available as an option on machines equipped with electric tank heat. The booster water heater is designed to maintain a minimum final rinse temperature of 180°F provided the incoming water to the booster heater is at least 110°F. Also available as an optional accessory is the model IB57 Infrared Booster Gas Water Heater. INSTALLATION UNPACKING Immediately after unpacking the dishwasher, check for possible shipping damage. If this machine is found to be damaged, save the packaging material and contact the carrier within 15 days of delivery. Prior to installation, test the electrical service to make sure it agrees with the specifications on the machine data plate which includes the optional electric booster, if equipped. Data plate for AM14T and AM14TC is located on the side of the control box. For AM14F, the data plate is located on the control box mounting bracket. INSTALLATION CODES Installation must be in accordance with state and local codes, or in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1 (latest edition) if applicable, and the National Electrical Code, ANSI/NFPA 70 (latest edition). In Canada, the installation standards are: CAN/CGA B149.1, CAN/CGA B149.2, and CSA C22.2 No.1 (latest editions). LOCATION Place the dishwasher in its operating location. Before finalizing the location, make sure that consideration has been given for the electrical conduit, water supply, drain connection, gas supply (if applicable), tabling (if needed), chemical feeder replenishment (if applicable), and adequate clearance for opening the doors. On models AM14T and AM14TC, the control box (Fig. 1) is mounted 45/8" below the dish table when shipped from the factory. It can be changed to 111/8" or 5/8" below the dish table by removing the two mounting bolts and reinstalling them in the holes provided. The dishwasher must be level before any connections are made. Turn the threaded feet (Fig. 1) as required to level the machine and adjust to the desired height. – 5 – On models AM14T and AM14TC, dish tables should be turned down and fitted into the dishwasher (Fig. 2). Use an NSF approved sealer between table and tank lip to prevent leakage. Fasten the tables to the tank lip with truss head screws. Dish tables are not required with model AM14F. High-temperature or gas heat dishwashers will probably require a hood or vent over the dishwasher in order to meet local codes. Low-temperature chemical sanitizing machines or low usage electric heat dishwashers may not require individual venting of the machine if the room is amply exhausted. Refer to pages 9 and 10 for venting and hood requirements. WATER REQUIREMENTS Proper water quality can improve ware washing performance by reducing spotting, lowering chemical supply costs, enhancing effectiveness of labor, and extending equipment life. Local water conditions vary from one location to another. The recommended proper water treatment for effective and efficient use of this equipment will also vary depending on the local water conditions. Ask your municipal water supplier for details about local water specifics prior to installation. Recommended water hardness is 4 – 6 grains of hardness per gallon. Chlorides must not exceed 50 parts per million. Water hardness above 6 grains per gallon should be treated by a water conditioner (water softener or in-line treatment). Water hardness below 4 grains per gallon also requires water treatment to reduce potential corrosion. Water treatment has been shown to reduce costs associated with machine cleaning, reduce deliming of the dishwasher, reduce detergent usage, and reduce corrosion of metallic surfaces in the booster water heater and dishwasher. Sediment, silica, chlorides, or other dissolved solids may lead to a recommendation for particulate filtration or reverse osmosis treatment. If an inspection of the dishwasher or booster heater reveals lime build-up after the equipment has been in service, in-line water treatment should be considered, and, if recommended, should be installed and used as directed. Contact your Hobart Service office for specific recommendations. PLUMBING CONN...
