4.4 COUPLING ALIGNMENT CHECK
No coupling alignment is required.
4.5 FLUID LEVEL CHECK
The 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 near the sump. If
the sump is properly filled, fluid should be visible in
the sight glass while compressor is in run mode.
The maximum fluid level is the level of the filler port.
4.6 ELECTRICAL PREPARATION--STANDARD

Required customer wiring is minimal, but should be
done by a qualified electrician in compliance with
