Chapter 3 Operation
Before compressor start-up, the operator should thoroughly read this manual. They should
strictly follow all related safety regulations including the related contents specified in the
manual and expertly master the related characteristics of the unit and its operation methods.
3.1 Initial Start-Up
a. Loosen the transport supports or bolts connected to air tank on the mounting plate of the
unit.
b. Connect the power supply cord and the grounding line. Check whether the voltage is
correct and the 3-phase voltage is balanced.
c. Check whether the electrical wiring is safe, secure and reliable.
d. Check whether the oil level in the oil-air tank is in a proper position.
e. Check whether the V-belt tension is correct.
f. Before initial start-up or restarting after 3-6 months long-term shutdown, add 0.5-1.5 L
of compressor lubricating oil into the compressor through the air inlet valve and rotate
the screw air end for several turns by hand. This is to prevent friction/heat damage to
the screw air end due to insufficient lubrication upon start-up.
g. At the first power-on, the power supply light will be lit and the current temperature will
be shown on the panel. Caution: If the phase of power supply is inconsistent, the
LCD window will indicate ‘wrong phase sequence’. At this point, any two phases of
power supply cable should be interchanged to correct the phase sequence.
h. Open the air tank discharge valve.
i. Rotation direction test: Although the unit has reverse phase protection measure, the
rotation direction test is still an important step in the initial start-up. It should be
repeated additionally after the motor is repaired or replaced.
j. Press ‘ON’ to start the compressor to rotate, and immediately press the ‘Emergency
Stop’ button. Make sure that the rotation direction of the compressor is consistent with
the arrow direction on the air end. If it is incorrect, just interchange any two phases of
power supply cables. The rotation direction of fan motor should be checked as well;
the cooling air should discharge upwards from the exhaust duct at the rear of the unit.
k. Restart the compressor. The unit will automatically turn to the star-delta starting
process. Close the valve at the air tank discharge to allow the discharge pressure to
rise, until the unit starts unloading. Check whether the unloading pressure is consistent
with the setting, and observe whether the indicating meters and lights are normal at the
same time. If any abnormal sound, vibration or leakage occurs, immediately press the
‘Emergency Stop’ button to shut down the machine for maintenance.
