Table 8 details the approximate 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.
For the most energy efficient operation, adjust the aquastat for the
minimum water temperature necessary to meet domestic hot water
needs. Refer to Figure 7. Use a small flat screwdriver to rotate the
temperature dial through the hole directly below the temperature
indication window. The temperature setting is aligned with the notch
in this window.
IT IS NOT NECESSARY TO REMOVE THE
COVER TO ADJUST THE TEMPERATURE SETTING. THE
AQUASTAT COVER SHOULD NEVER BE REMOVED
WITHOUT ELECTRICITY BEING FIRST DISCONNECTED.
