Our Compressor would like to emphasize the importance of providing adequate
grounding for air compressors. The common practice of grounding units to a
building’s structural steel may not provide adequate grounding protection, as
paint and corrosion build-up may exist.
All electrical supply cables must be adequately sized to prevent overheating due
to current draw.
Enclosure panels and drive grille must be fastened in place before starting the
compressor and never removed before lock out / tag out of the main power
supply.
A starter hole is provided for an incoming power connection. If a different location for the
starter hole is needed, the certified technician must make sure to keep control box clean
after the hole is created. The original hole must be capped if another hole is used. Inspect
incoming voltage to match the compressor’s specification. Inspect motor starter and
overload heater sizes. Check electrical connections L1-L2-L3 for tightness and cleanliness.
4.6 MOTOR ROTATION INSPECTION
Motor rotation must be checked after the wiring has been installed. Operating the
compressor in incorrect rotation will result in severe damage to the compressor and
warranty coverage will be voided. Motor rotation can be viewed through the opening in the
drive grille. The drive motor end of the compressor is marked with an arrow noting the
proper rotation.
To inspect rotors rotation, pull out the “EMERGENCY STOP” button and press once,
quickly press the “START” and “STOP” button in sequence, allowing the motor to turn 2
or 3 revolutions. Observe the drive shaft for correct direction. If reverse rotation is observed,
disconnect the power supply, reverse power input leads at the motor starter. Recheck for
proper rotation.
