Impinger I -–1000 Series Service Manual - Domestic 47
If readjustment of either the "MAX" or "MIN" pot. was necessary, the opposite m ust 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 neces sary.
Seal pots with Glyptol or nail polish.
NOTE: Occasionally a new board (Style 2 and 3 only) is so far out of adjustm ent 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.
