ZERO/SPAN Setting

Remark
:
1.
Before the compressor is shipped out from the factory, the zero and span knobs have been adjusted
to the best position. Do not adjust if not necessary. If adjustment is required, please use a small
screwdriver to turn gently (excessive force will cause damage in the knob).
2. When adjusting IGV, turn to the fully-close position and then do fully-open position adjustment.
※
Note
:
Because the forward turn of the actuator is opposite to the IGV connecting rod’s, the zero
knob is fully opened while the span knob is fully closed. To avoid risk, this adjustment should be done
by qualified personnel.
