Operation
2.5.1
Turn on/off air compressor
Make sure that the power supply voltage is the same with what’s indicated on
the data label: 230V/50 Hz or 115V/60 Hz. Use only 3-pole receptacles that
accept the compressor’s plug.
The on/off switch is located on the top of the pressure switch (see Figure 4).
To switch the unit on, turn the switch to position “1”. When switched on, the
compressor starts to build up pressure until the tank reaches the maximum
allowed pressure (8 bar/120 psi). The unit will then be automatically
switched off until air is used and the pressure in the tank drops to the
minimum operating pressure (6 bar/90 psi), at which point the compressor
automatically switches on.

2.5.2
Adjusting the outlet pressure
Outlet pressure can be adjusted using the knob on the filter/regulator so that
the air output is enough for the application, but the output will not exceed the
maximum air pressure specified by the application. Turn the knob clockwise
to increase the pressure and counter-clockwise to decrease pressure.
2.5.3
Air compressor operations
When properly installed, the compressor will operate within less than 50%
duty cycle. Check air connections and leaks regularly to prevent overheating
caused by compressor operating with larger than 50% duty cycle. Contact
Newport technical support if the air compressor is operating with larger than
50% duty cycle.
