COMPRESSOR MOTOR ROTATION
DIRECTION CHECK (
AT
INSTALLATION
)
After the compressor has been installed and the
electrical wiring is completed, perform following steps
to verify the direction of the compressor motor
rotation.
1. If the display screen shows “AUTOMATIC”,
press the UP arrow pad twice to navi-
gate to the Mode parameter. Press the
ENTER pad. The screen will display

place the machine in the Manual operating
mode.
2. Press the START and STOP
pads in succession to “bump start” the com-
pressor.
3. Observe the direction of rotation of the com-
pressor motor shaft. Verify with Operators
Manual for correct rotation.
4. Disconnect and lockout power according to
lockout/tagout procedure.
5. 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. Refer to the Compressor Oper-
ator’s Manual.
6. Perform above steps 1 - 3 again to confirm
proper motor/compressor rotation.
FAN MOTOR ROTATION CHECK (
AT
INSTALLATION
)
The VSD fan direction is affected by installation.
Verify the correct fan rotation using the following
steps:
1. With the compressor running, visually check
that the fan rotation is correct.
2. If it is incorrect, change the direction of the
fan motor by disconnecting power from the
compressor.
3. Disconnect and lockout power according to
lockout/tagout procedure.
4. Exchange any two of the three fan motor
leads at the fan motor starter. Refer to the
compressor Operator’s Manual.
5. Recheck the direction of the fan motor.
INITIAL START-UP AFTER
INSTALLATION

of the compressor following installation.
1. Verify that all preparations and checks nec-
essary for proper installation have been
made. Refer to the compressor Operator’s
Manual.
2. Read the preceding pages of this manual
thoroughly.

compressor. Compressor will begin operat-
ing in the default mode (Automatic) set at the
factory.
5. Check for possible leaks in piping.

verify nameplate pressure unload setting is
correct. The compressor should unload
when nameplate pressure is achieved. If
adjustments are necessary, see
Compressor
Adjustment Procedures on page 15.
7. Observe the operating temperature. Refer to
compressor Operator’s Manual for accept-
able operating range. If temperature
exceeds this range, check the cooling sys-
tem and installation environment.
NOTE
Variable speed drive (VSD) packages do
not require a main motor direction check
sincethe variable speed motor is set at
the time of manufacture.
