CAUTION
Adjust to proper specification, or the unit may not operate correctly.
Two new dip switches numbered 9 and 10 have been added to the improved “E” board to
better prevent possible freeze ups. These settings come factory set to the default setting
of 60 min. (OFF, OFF). Check the adjustment chart published in the Tech Specs for
proper settings. If the old board does not have these two dip switches, (only 8 instead of
10), leave setting as OFF, OFF.
