General Safety Precautions

To meet commercial hot water requirements, the tankstat is adjustable up to 190°F. However, water temperatures over 125°F. can cause severe burns in- stantly or death from scalds. This is the preferred starting point for setting the control for supplying general purpose hot water.

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

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.

Temperature	Time to Produce Serious Burn
120°F.	More than 5 minutes
125°F.	1-1/2 to 2 minutes
130°F.	About 30 seconds
135°F.	About 10 Seconds
140°F.	Less than 5	seconds
145°F.	Less than 3	seconds
150°F.	About 1-1/2 seconds
155°F.	About 1 second

TIME/TEMPERATURE RELATIONSHIPS IN SCALDS

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

Children, disabled and elderly are at high- est risk of being scalded.

See instruction manual before setting tem- perature at tankstat.

Feel water before bathing or showering.

Temperature limiting valves are available, see manual.

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

The temperature of the water in the storage tank can be regulated by setting the temperature dial on front of the tankstat. To comply with safety regulations, the tankstat was set at its lowest setting before shipment from the factory. The illustration below illustrates the tankstat 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 tankstat and turn wheel to desired setting. Tankstat is adjustable up to 190°F.

CAUTION!! - Hotter water increases the risk of

SCALDING!

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

NOTE: When this water heater is supplying general purpose hot water requirements for use by individuals, a thermostatically 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 infor- mation.
