How to operate new  and old air compressor? In order to meet the market needs, factories make diferent manufacturing plans  so the using compressed air need is also various. Beside, Factories often have backup machine( which is for little use) or or companies with seasonal production characteristics, air compressors operate seasonally. For many years of repair and maintenance Air compressors, air dryers we have a lot of trouble cases such as: the machine cannot start, the machine starts up with  load is immediately stopped, when the machine is turned on, the contactor is fired ....  One of the causes of the problem is air compressors is not used for a long time, leading to moisture of electrical equipments and oil filter, separator ... To help customers minimize the problems we would like to sumerize some notes when operating air compressors which is not used for a long time and the operation for newly air compressors.

1. Operation

 - Notes :

+ Before turn the power ON, make sure if 

 1- Installation

 2- Piping

 3- Electrical wiring have been properly completed.

 + After the installation or  after long unused time ( over a week) , run the machine by way off innitial start-up.  

2. Before  power on

  1. Be sure the power is OFF
  2. Be sure that the grounding is firmly  connected 
  3. Be sure discharge pressure gauge indicates 0.
  4. Detach  the door and remove Starter/control box cover  to ensure DIP, swithes  SW1, SW2 on the printed circuit board are corectly set. 
  5. Make sure that  oil level is around  the upper red line( but lower than the yellow line)

    -  Notes : Oil level lowers after starting.

3. Power on 

  1. Connect the  power  
  2. See if POWER lights glows on the compressor' s instrument panel. 
  3. Digital motor  display the run hours in 10 hour as a unit
  4. Fully open the valve on discharge side 

    Notes : For safey ,the unit will not operate for 5 seconds after the power is ON, even START button is pressed 
4. Operation

    + Make sure stability between about 65 and 100

    + Make sure that, about 20 minutes after starting , the refrigent pressure gauge reads 0,41 to 0,73 MPa. 

       0.73Mpa.

    + Make sure that about 20 minutes after starting the automatic condensate  trap start draining the condensate.

5. Stop

  1. Press STOP button. The compressor stop.
  2. Be sure that the pressure at  DISCHARGE PRESSURE GAUGE  indicates 0 (It returns to 0 for about 1 or 2 minutes afte stop)
  3. Fully close the valve on the discharge side.
  4. Disconnect the power.
