HEATER PROTECTION

A float is located in the wash tank to automatically turn off the heat supply if the water level is too low. Once the water level returns to a safe level, the heating circuit i s operational if heat is demanded.

Tank water is heated by steam, gas, or electricity.

REDUCED VOLTAGE CONTROL (STANDARD)

A control transformer is used to provide low voltage for the solid state control circuits. This control transformer also supplies 115 V.A.C. to the control components.

INSTALLATION

LOCATION

Adequate space must be available to open and service the control box (6, Fig. 1). The control box i s mounted 4-518" below the dish table height when shipped from the factory. I t can be changed to 12-518" below the dish table by removing two bolts and reinstalling in the two lower holes provided.

Set the dishwasher in i t s desired location. Adjust the height and level by turning the threaded feet (7, Fig. 1). Make sure the dishwasher i s level before making plumbing connections.

Dish tables (1, Fig. 2) should be turned down and fit into the dishwasher. Use a sealer between table and tank lip to prevent leakage. Fasten the dish tables to the tank lip with truss head screws.

Plumbing connections must comply with applicable sanitary, safety and plumbing codes.

INSTRUCTIONS AM-12

Drain

Connect the drain to the sewer using 2" pipe. Left-hand drain is standard. Interchange plug for a right-hand drain. If a grease trap i s required by code, it should have a minimum flow capacity of 42 gallons per minute. .

Water Supply

The supply water should have a temperature of 180"-195" F. minimum and have a flow pressure of 15 to 25 P.S-I. at the pressure gauge tee beside the fill (solenoid) valve.

Use 314" pipe for connecting the water supply line to line strainer which i s assembled directly ahead of the fill (solenoid) valve. The line strainer prevents foreign matter from reaching the solenoid valve. If flow pressure exceeds 25 P.S.I., a pressure reducing valve (not furnished) must be installed in the water supply line.

Gas Heat

Check gas data plate (9, Fig. 1) attached t o dishwasher or tag attached to gas burner tubing for type of gas to be used.

Connect gas burner to gas supply. Check gas burner compression fittings to assure they have not loosened during shipment.

A capped "tee" (not supplied) i s recommended to catch loose particles in front of the valve.

The burner is not adjustable. If line pressure is above 7" W.C. (natural gas) or 11" W.C. (L.P. gas), an additional regulator valve (not supplied) must be installed.

The burner is ignited automatically by solid state circuitry. There is no pilot light. Gas flow i s regulated by the temperature control circuit through a solenoid valve.

If a failure occurs in the gas heat control board or gas pressure, the reset button, located on the side of the gas burner control box, will pop out. This completely shuts off the gas heat system. To reset, push the button in. If system does not reset, contact an authorized Hobart service office.

Steam Heat

The steam supply must be between 15 and 50 P.S. I. flowing pressure. Steam flow i s controlled by a solenoid valve as well as a mechanical globe valve.

A M - 12 INSTRUCTION S

A 314" union connection, for steam supply line, is located behind the control box.

A solid state circuit board controls the steam valve t o provide shut-off. When the dishwasher i s not in use, close the globe valve in the line ahead of the solenoid valve.

ELECTRICAL COhINECTIONS

Before making electrical connections, check the specifications on machine data plate (4, Fig. 1) to assure they agree with those of your electrical service.

Electrical and grounding connections must comply

with	the a ~ ~ l i c a b~leo r t i o n sof the National Elec-
trical	cod;' and/or 'other local electrical codes.
