START-UP PROCEDURES
3.1 MOTOR ROTATION
DIRECTION CHECK
After the electrical wiring has been done, it is
necessary to check the direction of the motor
rotation. With the control system in MANUAL mode,
press the and pads in succession to
bump start the compressor. When looking at the
motor from the end opposite the compressor unit, the
shaft should be turning clockwise on all gear driven
models, and counterclockwise on direct drive
models. If the motor shaft is not turning in the proper
direction, disconnect the power to the starter and
exchange any two of the three power input leads,
then recheck rotation. A “Direction of Rotation” decal
is located on the coupling guard between the motor
and compressor to show proper motor/compressor
rotation.
Variable speed drive packages will have main motor
direction set at the time of construction, but the fan
direction is affected by installation. If fan-cooled,
ensure that fan rotation is correct. To change
direction, disconnect the power and exchange any
two of the three fan motor leads at the fan motor
starter.
3.2 INITIAL START-UP
PROCEDURE
The following procedure should be used to make the
initial start-up of the compressor.
1. Be sure that all preparations and checks
described in the Installation Section have
been made.
2. Read the preceding pages of this manual
thoroughly.
3. Jog motor to check for correct rotation of fan
(refer to Section 3.1 ).
4. Start the compressor in the desired operating
mode or .
5. Slowly open the shut-off valve to the service
line.
6. Check for possible leaks in piping.
7. Slowly close the shut-off valve to assure
proper nameplate pressure unload setting is
correct. The compressor will unload at
nameplate pressure. If adjustments are nec-
essary, see Control System Adjustment sec-
tion in the compressor operator’s manual.
8. Observe the operating temperature. Refer to
compressor operator’s manual for accept-
able operating range. If temperature
exceeds this range, the cooling system and
installation environment should be checked.
9. Open shut-off valve to the service line.
10. Reinspect the compressor for temperature
and leaks the following day.
3.3 SUBSEQUENT START-UP
PROCEDURE
On subsequent start-ups, check that the proper level
is visible in the fluid sight glass and simply press the
START or AUTO MODE button. When
the compressor is running, observe the instrument
panel and maintenance indicators.
3.4 SHUTDOWN PROCEDURE
To shut the compressor down, simply press the
STOP button.
