5.3 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. Start the compressor by pushing the START but-
ton.
5. Check for possible leaks in piping.
6. Slowly close the shut-off valve and check that the
setting on the pressure switch is set correctly. If set
correctly, the compressor will unload at the desired
unload pressure. If adjustments are necessary, see
Control System Adjustments in the Maintenance
Section of the manual.
7. Observe the operating temperature. If the oper-
ating temperature exceeds 200°F (93°C), the cool-
ing 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.
5.4 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 button. When the compressor is
running, observe the instrument panel and mainte-
nance indicators.
5.5 SHUTDOWN PROCEDURE
To shut the compressor down, simply press the
STOP button.

BLOWDOWN VALVE
being used at the service line.
Opens a pressure line between the sump and Sullicon
Control allowing the Sullicon Control to regulate air delivery
according to the air demand.
Bypasses the pressure regulator valve causing the Sullicon
Control to close the inlet valve and spiral valve (when pro-
vided) to unload when the compressor reaches maximum op-
erating pressure.
Senses service line pressure. When line pressure reaches
maximum setting the pressure switch signals the solenoid
valve to unload the compressor.
Vents sump pressure to the atmosphere during unload con-
ditions and shutdown.
