START---UP PROCEDURES

4.1 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 ON/OFF pad twice in succession to bump start
the compressor. When looking at the motor from
the end opposite the compressor unit, the shaft
should be turning counterclockwise for direct drive
packages and clockwise for gear driven packages.
If the motor shaft is not turning in the proper direc-
tion, disconnect the power to the starter and ex-
change any two of the three motor leads, then re---
check rotation. A "Direction of Rotation" decal is lo-
cated on the coupling guard between the motor
and compressor to show proper motor/compres-
sor rotation.
4.2 INITIAL START---UP PROCEDURE
The following procedure should be used to make
the initial start---up of the compressor:
1. Read the preceding pages of this manual thor-
oughly.
2. Be sure that all preparations and checks de-
scribed in the Installation Section have been
made.
3. Crack open the shut off valve to the service line.
4. Set the compressor in MANUAL mode and start
the compressor by pressing the ON/OFF pad.

5. Check for possible leaks in piping.
6. Slowly close the shut---off valve and check that
the maximum pressure (P2) and pressure differ-
ential (P2) are correctly programmed.
7. Observe the operating temperature. If the oper-
ating temperature exceeds 205_F (96_C), the
cooling system or installation environment
should be checked.
8. Observe return line sight glasses and mainte-
nance indicators.
9. Open shut---off valve to service line.
10. Reinspect the compressor for temperature and
leaks the following day.
4.3 SUBSEQUENT START---UP PROCEDURE
On subsequent start---ups, check that the proper
level is visible in the fluid sight glass and simply
press the ON/OFF pad. When the compressor is
running, observe the control panel for mainte-
nance indications.

4.4 SHUTDOWN PROCEDURE

To shut the compressor down, simply press the
ON/OFF pad. If STOP MODE TIME is enabled, a 0
--- 30 sec. delay before shutdown will occur when
ON/OFF pad is pressed. This may be overriden by
pressing "EMERGENCY STOP".
