IMPORTANT:
The scale plate is only for reference and for more
precise setting a pressure gauge should be used.
Adjustment:
Low Pressure Switch
Cut out on pressure fall
with automatic reset.
Scale plate directly indicates
the Cut In and the Differential
set points.
Adjustment:

IMPORTANT:
After installing and adjusting pressure switch run the
controlled equipment several times (at least three
cycles) at normal operating conditions.
Turn the screw clockwise to lower the set point.

NOTE:
Cut Out set point must be above absolute vacuum!
If the Differential is set too high then the switch
will not stop the compressor.
Turn the screw clockwise to lower the set point.
