SAVE THESE INSTRUCTIONS

GENERAL All AM16X models are shipped from the factory for a straight through conguration and can be easily converted to a corner operation. The AM16-BASX, AM16T-BASX, AM16VL-BASX and AM16VLT-BASX dishwashers are designed to operate in hot water sanitizing mode only. Designated by the NSF temperature requirements of 150°F Wash and 180°F Rinse. These temperatures can be found on the label located under the controls on the lower part of the machine. The AM16SCBX and AM16VLSCBX dishwashers are designed to operate in chemical sanitizing mode only. Designated by the NSF temperature requirements of 120°F Wash and 120°F Rinse. These temperatures can be found on the label located under the controls on the lower part of the machine. The serial number can be found on the machine data label located at the bottom of the front right corner of the machine. Hobart supplied chemical pumps ship standard with all AM16SCBX and AM16VLSCBX models. Chemical pumps are available as an accessory kit (eld installed) for all other models or contact your chemical representative for a chemical feeder system to be supplied and installed by others. The wash pump motor is rated 2 H.P. and has thermal overload protection. The ll line incorporates an air gap on all models to prevent any reverse ow of water from the dishwasher into the potable water supply. The unit, once turned on, lls the wash tank to the appropriate level and automatically stops lling once the level is reached. A pressure transducer reads the water level in the wash tank and shuts off the heat supply if the water level becomes too low. When the water returns to the proper level, the heating circuit becomes operational again. An automatic pumped drain and pumped rinse system are standard on all models. A frame mounted 7.1kW electric booster water heater is equipped on all hot water sanitizing models. The booster water heater is designed to maintain a minimum nal rinse temperature of 180°F provided the incoming water is at least 110°F. For ventless models AM16VL-BASX and AM16VLT-BASX, the booster water heater is designed to maintain a minimum nal rinse temperature of 180°F with cold incoming water of at least 55°F. Models AM16SCBX and AM16VLSCBX are provided with a 4.3kW electric booster water heater. The booster water heater is designed to maintain a minimum nal rinse temperature of 120°F provided the incoming water is at least 90°F (120°F recommended). Ventless models AM16VL-BASX, AM16VLT-BASX, and AM16VLSCBX do not require a vent hood. They use an internal condensing system to minimize the water vapor escaping from the unit during loading and unloading. High-temperature AM16-BASX and AM16T-BASX models typically require a hood or vent over the dishwasher 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 10 - 11 for venting and hood requirements. Verify with local code ofcials for nal determination.– 5 – 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 5 days of delivery. NOTE: Use caution when using a forklift to remove machine from skid. DO NOT use door lift handle to move machine, as it will cause door lift issues. Prior to installation, test the electrical service to ensure it agrees with the specications on the machine data plate. The dishwasher data plate is located at the lower right hand corner of the machine. INSTALLATION CODES Installation must be in accordance with state and local codes and the National Electrical Code ANSI/NFPA70 (latest edition). In Canada, the installation code is CSA 22.1 (latest edition). LOCATION Before nalizing the location, make sure that consideration has been given for the electrical conduit, water supply, drain connection, venting (if applicable), tabling (if needed), chemical feeder replenishment (if applicable) and adequate clearance for opening the door. 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. The edge of dish table that overhangs the AM16 wash tank should be turned down and tted over the top of the dishwasher tank (Fig. 2). Apply an NSF approved sealant between the overhang of the dish table and the inner wall of the wash tank to prevent leakage (Fig. 2). Fasten the dish tables to the inner wall of the wash tank with non-rusting truss head screws or rivets (Fig. 2).

Water Requirements Proper water quality can improve ware washing performance by reducing spotting, enhancing effectiveness of labor and extending equipment life. Water conditions vary from one location to another. The recommended proper water treatment for effective and efcient use of this equipment will also vary depending on the local water conditions. Ask your municipal water supplier for details about local water conditions prior to installation. Recommended water hardness is 3 grains of hardness per gallon or less. Higher hardness may cause excessive formation of lime scale. Water hardness above 3 grains per gallon requires water treatment. Water treatment has been shown to reduce costs associated with machine cleaning, reduce deliming of the dishwasher and reduce detergent usage in the dishwasher. Chlorides must not exceed 50 ppm. High iron levels in the water supply can cause staining and may require an iron lter. High chloride levels in the water supply can cause pitting and may require a chloride removal system. Contact your local water treatment professional for proper water treatment. Sediment may require a particulate lter. Dissolved solids may require water treatment such as a water softener, reverse osmosis system, etc. Contact your local water treatment professional for proper water treatment. If an inspection of the dishwasher or booster heater reveals lime build-up after the equipment has been in service, water treatment is recommended. If a water softener is already in place, ensure there is a sufcient level of salt. Contact your Hobart Service ofce for specic recommendations. Water Supply Connection The plumber connecting this machine is responsible for making certain that water lines are THOROUGHLY FLUSHED OUT BEFORE connecting to the dishwasher. This "ush-out" is necessary to remove all foreign matter, such as chips (resulting from cutting or threading of pipes) pipe joint compound from the lines; or, if soldered ttings are used, bits of solder or cuttings from the tubing. Debris, if not removed, may lodge in the dishwasher's plumbing components and render them inoperative. Manual valves or solenoid valves fouled by foreign matter and any expenses resulting from this fouling are NOT the responsibility of the manufacturer and associated repair costs are not covered under warranty. Water supply requirements are as follows: Model Sanitizing Mode Connection Water Supply Minimum Maximum Recommended AM16-BASX AM16T-BASX Hot Water Sanitizing Hot Water 110°F (43°C) N/A 140°F (60°C) AM16VL-BASX AM16VLT-BASX Hot Water Sanitizing Cold Water 55°F (13°C) 90°F (32°C) 65°F (18°C) AM16SCBX Chemical Sanitizing Hot Water 90°F (32°C) N/A 120°F (49°C) AM16VLSCBX Chemical Sanitizing Hot Water 90°F (32°C) N/A 120°F (49°C) Cold Water 55°F (13°C) 90°F (32°C) 65°F (18°C)

WATER SUPPLY REQUIREMENTS– 9 –

AM16VLSCBX models require both a cold water supply and a hot water supply. On AM16VL-BASX, AM16VLT-BASX and AM16VLSCBX installations, the cold water supply must not exceed 90° F (32° C) for proper operation. Optimal results are obtained when cold water supply temperature is below 65° F (18° C). For best results, it may be necessary to use 1/2" pipe for cold water pipe size and minimize the distance between the dishwasher and the entrance into the building. Pipe insulation will also improve results. If cold water supply temperature is consistently above 90° F (32° C) or if excessive water vapor or steam is entering the dish room after the condensing cycle is complete, contact Hobart Service to increase condensing time. Required owing water pressure to the dishmachine is 15 – 65 PSIG. If owing pressures higher than 65 PSIG are present, a pressure regulating valve must be installed in the water line to the dishmachine (by others). If owing pressure is less than 15 psi, improper machine operation may result. All AM16X models are equipped with a pumped rinse system; therefore, a water pressure gauge is not required and is not supplied with the machine. The water pressure regulator must have a relief bypass. Failure to use the proper type of pressure regulator may result in damage to the unit. A manual shutoff valve (not supplied) should be installed upstream of the ll hose to accommodate servicing the machine. It is recommended that a line strainer (not supplied) be installed in the supply line between the manual shutoff valve (not supplied) and the connection point on the machine. All machines ship standard with a 96" long stainless steel braided ll hose with a 3/4" female garden hose tting. A second ll hose is shipped for machines equipped with both hot and cold water connections. Make plumbing connections with 1/2" minimum copper piping OD (3/4" recommended), with a 3/4" male garden hose tting (not supplied). Drain Connection A drain hose, 5/8” inside diameter and 6’ long, is provided with machine. This should be securely plumbed into a drain. Use care not to kink the hose. Drain must have a minimum ow capacity of 18.5 gallons per minute. The drain hose height cannot exceed 40” above nished oor. If a grease trap is required by code, it should have a minimum ow capacity of 18.5 gallons per minute. For -BASX and VL-BASX models, pumped drain air gap kit is available through sales using accessory code PUMPDRN-AIRGAP or service kit part # 00-562492.– 10 – VENTING REQUIREMENTS NOTE: Any listed and labeled factory-built commercial exhaust hood tested in accordance with UL Standard 710 by a nationally recognized testing laboratory, must be installed according to the terms of its listing and the manufacturer’s installation instructions. Rate of Exhaust Flow Calculations Based on the 2018 International Mechanical Code. The minimum net airow for Type II hoods used for dishwashing appliances shall be 100 cfm per linear foot of hood length. The net quantity of exhaust air shall be calculated by subtracting any airow supplied directly to a hood cavity from the total exhaust ow rate of a hood. Ventless models AM16VL-BASX, AM16VLT-BASX and AM16VLSCBX do not require a Type II vent hood. According to 507.3 of the 2018 IMC, Type II hoods are not required where the heat and moisture load is incorporated into the HVAC system design. See Table A (page
