Chapter VII Operations

I. Trial run of new compressor
1-1. Connect the power cord and ground wire to check whether the principal voltage is correct and whether the three-phase voltage is
balanced. The compressor operates with best performance in case of three-phase voltage ±5%.
1-2. Loose the fixing bolts for transportation from the vibration isolation table on the base.
Note: It is necessary to re-tighten the fixing bolts for transportation while handling the compressor to prevent the anti-vibration pad from
being damaged due to tilting or vibration or from moving out of place.
1-3. Check whether the oil level in the oil-air separator tank is between the two red lines of the oil level sight glass.
1- 4. If the test run is conducted long after delivery, fill an appropriate amount of lubricating oil from the intake valve and turn the air
compressor by hand to prevent the air compressor from burning out during startup due to oil loss; be sure to prevent foreign matters
from falling into the compressor body so as to avoid damaging the compressor. (Refer to quantity of oil filled for long-term shutdown)
Note: Do not supply voltage to the compressor at this time.
1-5. Supplying voltage to the electrical cabinet of compressor
Note: If the phase sequence of the power supply does not match with the specified phase sequence, the HMI will show an alarm signal and
the compressor cannot be started.
1-6. Rotation direction test: If the compressor rotates when the "ON" button has been pressed, immediately press the "Emergency
stop" button to check the rotation direction of the compressor. For correct rotation direction, please see the arrow on the compressor
body. If the rotation direction is wrong, exchange any two of the phase lines R, S, and T. In addition, it is necessary to pay attention to the
rotation direction of the cooling fan.
Note: the power must be cut off while working with the electrical devices, and live operation is strictly prohibited.
Although the compressor has been tested during production, it is important to conduct the rotation direction test during the trial run of
new compressor.
Note: Inverse phase protection is to detect the phase of the power supply. After the motor is overhauled, the rotation direction test must
be conducted again.
1-7. Startup: Press "ON" button again to start the compressor.
Note: This compressor is a piece of fully automatic equipment. The intake valve begins to work 8 seconds after the compressor is started
1-8. Check whether the LCD and audible and visual alarm work normally; if any abnormal sound, vibration or leakage occurs to the
compressor, immediately press the "Emergency stop" button to stop the compressor for overhaul.
1-9. Stop: When the "OFF" button is pressed, the compressor stops working after a delay of 10 seconds, and the HMI displays the
countdown to stopping the compressor.
Note: When the "OFF" button is pressed, the relief valve of the compressor releases air to unload and the timing relay starts to count
time. After about 10 s, the motor stops running. The compressor is started after a delay of 20 s if it is required to be restarted.
Note: For a normal condition, please do not use "Emergency stop" button to stop the compressor.
II. Daily compressor pre-start check
Daily compressor pre-start check is necessary for normal operation in order to prolong the service life of the compressor, so be sure to
perform it carefully.
2-1. Open the four-sided doors in the event of a power failure to check for dust in the compressor and the dust screen for dust. Use an air
gun to blow off the dust inside the compressor (if necessary) and close the doors.
2-2. Check the power supply and power cord for looseness, damage on surface or electric leakage, and check that they are intact before
powering on.
2-3. Check whether all doors are closed before starting, and check whether the connected devices around are in the standby state.
2-4. Check whether there is any alarm message shown on the LCD. If at least one message is shown, it is required to process according to
the information feedback, and then the compressor is allowed to be started.
2-5. Clean and replace the air filter, pre-filter and oil filter regularly according to their working environment.
2-6. Clean the cooler regularly according to the working environment; if necessary, remove it to clean its cooling fins with the cleaning fluid
for air conditioner.
