SECTION L: GENERAL SAFETY PRECAUTIONS

To meet commercial water use needs, the temperature Hi-Limt on this hot water heater is adjustable up to 210°F. However, water temperatures over 125°F can cause severe burns instantly or death from scalds. The preferred starting point for setting the control for supplying general purpose hot water is 125°F.

Safety and energy conservation are factors to be considered when setting the water temperature on the thermostat. The most energy efficient operation will result when the temperature setting is the lowest that satisfies the needs consistent with the application.

Water temperature over 125°F can cause severe burns instantly or death from scalds.

Children, disabled and elderly are at highest risk of being scalded.

See instruction manual before setting temperature at water heater.

Feel water before bathing or showering.

Temperature limiting valves are available, see note below.

Maximum water temperatures occur just after the heater’s burner has shut off. To determine the water temperature being delivered, turn on a hot water faucet and place a thermometer in the hot water stream and read the thermometer.

The following chart details the relationship of water temperature and time with regard to scald injury and may be used as a guide in determining the safest water temperature for your applications.

TIME/TEMPERATURE RELATIONSHIPS IN SCALDS

The temperature of the water in the hot water heater can be regulated by setting the temperature dial on front of the thermostat. To comply with safety regulations the thermostat was set at its lowest setting before the hot water heater was shipped from the factory. The illustration below shows the thermostat and how to adjust the water temperature.

To adjust the water temperature, insert a small straight screwdriver into slotted screw in hole in front of thermostat and turn wheel to desired setting.

CAUTION!!

- Hotter water Increases the risk of SCALDING!

 

 

There is a Hot Water SCALD Potential if the thermostat is set too high.

Adjustment

Screw

NOTE: When this hot water heater is supplying general purpose hot water requirements for use by individuals, a thermo- statically controlled mixing valve for reducing point of use water temperature is recommended to reduce the risk of scald injury. Contact a licensed plumber or the local plumbing authority for further information.
