4.5 COUPLING ALIGNMENT CHECK

In preparation for the factory test, the coupling sup-
plied with your compressor is properly aligned for
operation. However, due to shipping and handling,
it is necessary to recheck the coupling alignment.
Refer to Coupling Alignment procedure explained
in the Maintenance section of this manual.

4.6 FLUID LEVEL CHECK

Your air compressor is also supplied with the
proper amount of fluid. However, it is necessary to
check the fluid level at installation. The level is
checked by looking at the sight glass located on
the sump. If the sump is properly filled, the coolant
level should fill 1/2 of the sight glass when the com-
pressor is shutdown.

4.7 ELECTRICAL PREPARATION

Interior electrical wiring is performed at the factory.
Required customer wiring is minimal, but should

installer.
