•For protection against excessive pressures and temperatures, local codes require the installation of a temperature-and-pressure (T&P) relief valve certified by a nationally recognized laboratory that maintains periodic inspection of production of listed equipment of materials, as meeting the requirements for Relief Valves and Automatic Gas Shutoff for Hot Water Supply Systems. ANSI Z21.22-1971. THE CUSTOMER IS RESPONSIBLE TO PROTECT PROPERTY AND PERSONNEL FROM HARM WHEN THE VALVE FUNCTIONS.

•All water heaters have a risk of leakage at some unpredictable time. IT IS THE CUSTOMER'S RESPONSIBILITY TO PROVIDE A CATCH PAN OR OTHER ADEQUATE MEANS, SO THAT THE RESULTANT FLOW OF WATER WILL NOT DAMAGE FURNISHINGS OR PROPERTY.

•The installation must conform to these instructions and any local authority having jurisdiction. Grounding and electrical wiring connected to the unit must also conform to the latest version of the National Electric Code NFPA-70.

WATER HEATER PLACEMENT

NOTE: For most effective operation, install the booster heater as close as possible to the dishwasher. If the distance between the booster and the dishwasher exceeds NSF requirements, recirculation methods must be employed.

1.Place the heater on a solid, level foundation in a clean, dry location as near as possible to the dish washing machine.

2.The water heater should be protected from freezing and waterlines insulated to reduce energy and water waste.

3.Leave a minimum of 18” clearance for element withdrawal and control access.

4.Do not install in an area where flammable liquids or combustible vapors are present.

SLIDE BRACKETS FOR HANGING SUPPORT MOUNTING

1.Weld slide rails to bottom of dishtable. Spacing should be 17” for J6 models 4 to 18kW and 22” for J6 models 24 to 58.5kW. J16 models are not designed for use with slide brackets.

2.Attach slide bracket angles to heater with #8 sheet metal screws. It will be necessary to drill 1/8” holes into heater jacket for screw pilot holes.

3.Slide heater onto slide rails under dishtable.

PIPING INSTALLATION – See Diagrams

NOTES:

•Dielectric couplings should be used in connecting dissimilar metals to prevent electrolysis.

•No check valve may be installed in the supply line to the booster.
