Installation and precautions
Note:
1. All joints should be wrapped with raw tape to avoid air leakage
2. All joints should be tightened.
3. The default pipe provided by OPPAIR is 1.5m long, and the length can be changed according to customer requirements.
4. The following accessories need to be purchased separately. Please consult the sales staff for details.
Installation steps:
1.The following things need to be prepared in advance (purchased separately or prepared by yourself): Precision filter, pipe, joint, tools (raw tape, wrench, etc.), wire.
2. Pre-install the accessories of the air tank (pressure gauge/safety valve/drain valve)
3. Connect the pipe + joint from the air compressor outlet to the air tank. Note: All joints must be wrapped with raw tape and sealed tightly to avoid air leakage.
4. Install the accessories on the air tank, including the pressure gauge, safety valve and drain valve. After wrapping the raw tape, install them on the air tank in sequence.
The drain valve needs to be connected to an automatic drain valve (this needs to be purchased separately) or you can also drain manually regularly by opening the drain valve at the bottom.
5. Connect the Q-level precision filter to the air tank outlet.
Pay attention to the direction of the arrow and do not install it in reverse.

6. Connect the pipe + connector from the Q-level precision filter to the air dryer.
7. Connect the precision filter (P-level + S-level) and the automatic drain valve at the outlet of the air dryer
Pay attention to the direction of the arrow and do not install it in reverse. Install the P-level first, then the S-level
8. Connect the final outlet pipeline and connect the pipeline to the final air-using machine.
Precautions before use：
1. Open the door panel to check whether there is any foreign matter inside the air compressor? Is there a filter element placed inside when it was shipped?
2. Open the door panel of the electric panel and check whether the internal wires/electrical appliances are loose?
3. Check whether the oil level of the oil level mirror of the oil and gas separator is normal? (When not in operation, the oil level must be between the lowest line and the highest line)
4. Check the nameplate of the air compressor to see if the air compressor voltage is consistent with the on-site voltage?
5. After the above is no problem, connect the power supply. (Be sure to connect tightly to avoid loose connection of the wires)
6. There is a power cord on the back of the air dryer. Connect the power supply of the air dryer. Small models are generally single-phase electricity.
7. Release the emergency stop (the emergency stop of the new air compressor is locked).
During operation, the emergency stop button cannot be pressed at will and can only be used for emergency shutdown.
8. Start the machine. Press the air dryer start button. Start the air compressor 3-5 minutes after the air dryer is turned on.
Start the air compressor: Press the controller: Start keyboard for 3 seconds. Start starting. If the screen cannot start normally, it will display: Phase sequence error. Turn off the main power supply, swap the positions of any two live wires at the air compressor power supply, and restart it to run normally.
9.Open the valve of the air compressor outlet.
10. During operation, you need to check: Is there any air leakage inside the air compressor? Is the oil level of the sight glass reasonable? Is there any air leakage in the connected pipeline?
11. Open the valves of the precision filter and the air tank.
12. If there is an early warning on the screen/other problems are encountered, please contact us as soon as possible, and do not adjust the controller parameters at will. When maintenance is needed, we have professional maintenance videos, please contact us.
