3.1 MOTOR ROTATION DIRECTION CHECK

After the electrical wiring has been done, it is nec-
essary 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.
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 re-
check 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 direc-
tion, 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 thor-
oughly.
3. Jog motor to check for correct rotation of fan
(refer to Section 3.1).
START-UP PROCEDURES
4. Start the compressor in the desired operating
mode
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 pres-
sure. If adjustments are necessary, see Control
If the
System Adjustment section in the compressor
operator's manual.
8. Observe the operating temperature. Refer to
compressor operator's manual for acceptable
operating range. If temperature exceeds this
range, the cooling system and installation envi-
ronment 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
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.
