In order to ensure durability, stability and safety when using and operating screw air compressors, proper operation is critical. Folowing are some notes when operating screw air compressors.

 

Notes:

-  Do not operate the machine at a excesive pressure of the machine. It'll causes overload for the engine or can destroy some parts or even shutdown.

-   Check the causes and set the necessary functions for air compressors  to avoid being stopped by other safety devices.

-    When HISCREW automatically and restarts continuously, either high ambient temperature or high humidity, open the oil discharge valve / condenser discharge valve to discharge the condensate regularly. If you do not regularly do this, the internal components and compressors (rotor, bearings ...) cause an oil failure or damage.

1.Before power 
-  Check that the oil level stays between the two red lines. However, the oil level may be slightly lower during operation. Check again the oil level when it works.

2. Connect  power 
- Power connection.
- POWER led on the control panel light up
- Fully open the discharge  valve.
- Open all valves to  condensate drain trap

3.Operating                           
 Press the START button, be sure air compressor start   
Cautions : 
-   Start air dryer before 3-5 min, then air compressor stars.
-  Be sure oil level is between two red lines( if it is lower than lower red line, immediately stop and perform corectly adding oil process)

-   Make sure that 5-10 minutes after starting , the refrigerant pressure gauge reads 0,41 to 0,73 MPa
-   Make sure that about 20 minutes after starting , the automatic condensate trap starts draining the condensate.
4. Stop

 1: Press STOP button the compressor stop 

Notes: Be sure discharge pressure gauge indicates 0( It returns to 0 for about 1 to 2 minutes after stop)
 2: Fully close the valve on discharge side and disconnect the power.
