Tank Heat Temperature Adjustment
A temperature control board is provided in the control
panel for easy adjustment of tank temperature.
Though tank temperature is set during factory testing
it is sometimes necessary to re-adjust the temperature
at start-up.
1. Locate the temperature control board (P/N DE9-
251). Use the control panel layout drawing located
in PART 7, Electrical Schematics and Parts.
2. Adjust the tank temperature to the correct
temperature by turning the potentiometer located
on the temperature control board. An arrow on the
potentiometer indicates increase.
