6. STARTUP OPERATION [Startup Operation of the Air Compressor]
②
Check the LCD for operating pressures and
temperatures. Verify that: Discharge air pressure
(DIS. PRESS), interstage air pressure (INTSTG. P),
oil pressure (OIL PRES), 1st stage discharge air
temperature (DIS. TEMP 1), 2nd stage discharge air
temperature (DIS. TEMP 2), 2nd stage suction
temperature (2ND SUC. T.) and oil temperature (OIL
TEMP) are within the normal range, as shown in the
Proper Pressure/ Temperature Indications on LCD
table below.
③
Verify that the condensate is discharged intermediately
from the intercooler/aftercooler drain port.

WARNING
During inspection of the operation of the air
relief valve, use the appropriate facial
protection. High pressure air containing dust
particles can cause severe injury.
CAUTION
Ensure that the main motor is properly
greased during the start up commissioning. If
the air compressor has not been operated for
(3) months, grease before restarting.
(
9.4
13
)
①
Grease the main motor bearing at once. Refer to the
9.4
13
for the detail.
②
Verify that the air compressor has proper rotation.
If rotation is not correct (phase reversal), change 2 of
the 3 wires of the power cable.
③
Verify that the oil pressure rises 18 psi (0.12 MPa) or
greater within ten (10) seconds after starting the air
compressor. If pressure has failed to rise, press the
STOP
button and clean the oil strainer. And/or
regulate the oil pressure by oil relief valve.
(
3.7.2)
④
In the case of the fixed speed type, switch to full load
operation within 15 seconds, and for the V type,
switch in approx. 10 seconds.
⑤
Raise the pressure step by step as illustrated below.

Pressure Raising Pattern
for the rated
discharge pressure
102 psi (0.70MPa)
Time
0.5hr 1hr 1.5hrs 2hrs
Method of Raising Pattern:
During startup operation, raise the discharge pressure by
following these steps. 1.) After starting the air compressor,
operate at 30psi (0.20MPa) for 30 minutes with the discharge
stop valve completely open. 2.) Raise the pressure 15 psi
(0.1MPa) (close the discharge stop valve) every 15 minutes
until the pressure reaches the rated pressure. During the
startup operation, perform this method without any failures.
6.1.2 Starting
①
Fully open the discharge stop valve, and press the
START
button.
