SECTION B: General Safety
Time/Temperature Relationships in Scalds
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.

Table B: Time to Produce Serious Burn
The temperature of the water in the heater can be regu- lated by using the Raypak Modulating Temperature Control. To comply with safety regulations, the control is set at 120°F when shipped from the factory (Mode 3 default setting for Tank Target).
To adjust the water temperature, follow the instruction for the operation of the control starting on page 28 of this manual. The control is shown below for identifica- tion purposes only. (See Fig. 4.)

CAUTION: Hotter water increases the risk of scald- ing! There is a hot water scald potential if the thermostat is set too high.
