1. The selector switch is moved to the manual position.
2. Open the exhaust valve of the compressor. 3. The slide valve pointer is at the "0" position, which is the 10% load position.
4. Press the electric heating button, the heating lamp turns on, and after the oil temperature rises to 40 ° C, press the heating stop button.
5. Press the water pump start button to supply water to the oil cooler.
6. Press the oil pump button to start the oil pump. At the same time, the oil return solenoid valve C opens automatically.
7. After 5 seconds to 10 seconds, the pressure difference between oil pressure and exhaust pressure can reach 0.4 ～ 0.6Mpa. Press the host, the start button, the compressor starts, the bypass solenoid valve A is automatically opened, and the oil return solenoid valve C Close automatically.
8. Observe the suction pressure gauge and gradually open the suction shut-off valve.
The compressor enters the running state, the A valve is automatically closed, and the oil pressure regulating valve is adjusted so that the difference between oil pressure (injection pressure and exhaust pressure) is 0.15 ～ 0.3Mpa
9. After the compressor's running pressure and temperature difference are normal, check the seal of each moving part, temperature measurement and pressure measurement point.
1. Hit the energy adjustment handle in the load reduction position to make the slide valve back to "0".
2. Press the host stop button to stop the host.
3. Close the suction valve.
4. Stop the oil pump.
5. Stop the water pump.
