ELECTRICAL WIRING AND CONTROL
SETTINGS – FINAL CHECK LIST
____ 1. Does the feeder line voltage correspond to the unit
voltage? Check the unit nameplate or motor terminal
connection.
____ 2. Are the feeder wires correctly sized for the load?
____ 3. Have all the power terminals in the control panel
been checked for tightness? This is imperative since
stranded wires tend to “flow” and become loose
after initial installation.
____ 4. Are the pressure controls correctly set? The pres-
sure switch needs to be set for proper operation.
Any subsequent change in system operating condi-
tions may require resetting the controls. For best
results, use compressed air and a continuity meter
(across the switch) to reset the controls. The legend
plate on the control indicates approximate readings
only, therefore, should be used with caution.
