Impinger I -–1000 Series Service Manual - Domestic 47
If readjustment of either the "MAX" or "MIN" pot. was necessary, the opposite must always be
checked until both "MIN" and "MAX" are in proper adjustment.
Measure the speed of the conveyor and adjust the time/temp. display if necessary.
Seal pots with Glyptol or nail polish.
NOTE: Occasionally a new board (Style 2 and 3 only) is so far out of adjustment that you will be
unable to adjust the correct voltage. To correct, turn both the "MAX" and "MIN" pots 10 turns in
either direction and then 5 turns in opposite direction. This will center the
pots and allow them to be calibrated. If after this procedure, the board will not adjust,
it is probably defective.
