Time/Temperature
Relationships in Scalds
The temperature of the water in the storage tank heater can be regulated by setting the temperature dial on front of the tankstat. To comply with safety reg- ulations, the tankstat was set at its lowest setting before shipment from the factory.
Fig. 1 illustrates a mechanical tankstat. 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. Thermostat is adjustable up to 190°F.

DANGER: There is a Hot Water SCALD Potential if the tankstat is set too high.
CAUTION: Hotter water increases the risk of
SCALDING!
NOTE: When this 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 information.
