5-2-2：PRESSURE SWITCH
The pressure switch located on the compressor unit acts as a pilot device activating the coil
on the magnetic starter except on contractor and professional units where the pressure
switch would act as a pilot device activating the motor。The pressure switch cut in/cut out
has been preset at the factory，do not tamper with the settings。 Never bypass or remove
this switch ，as serious damage to equipment or personal injury could result from too high of
an air pressure。Consult your local distributor or service center should the switch not be
operating properly。
5-2-3：Do not modify the plug that has been provided，if it does not fit the available outlet，the
correct outlet should be installed by a qualified electrician。If these grounding instructions are
not completely understand，or if in doubt as to whether the compressor is properly
grounded，have the installation checked by a qualified electrician。
5-2-4：PUMP ROTATION
The compressor is to be wired in a manner that the rotation of the flywheel causes the air to
be blown over the pump。This allows the pump to cool properly。Rotate the unit with an arrow
on the belt guard or motor。
