[Refrigeration equipment installation works in the general provisions of the refrigeration unit starts running]

 1. Start the compressor and check oil pressure immediately after the compressor speed to be stable, its hydraulic device complies with the relevant technical documents (specifically for the pump to start the pump).

2. The displacement compressors should start slowly open the suction shut-off valve and the throttle valve.

3. Check the safety of the protective relay, action should be sensitive.

4. The provisions should be based on site conditions and equipment technical documents, determine the minimum load required operation time.

5. The operation of the process should be one of the checks and make a record:

(1) height and all parts of the oil tank of the oil supply situation.

(2) lubricating oil pressure and temperature.

(3) suction and discharge pressure and temperature.

(4) into the drainage temperature and the cooling water supply.

(5) whether the abnormal sound of moving parts, connecting parts loose, leaks, oil spills, leaks and other phenomena.

(6) the motor current, voltage and temperature.

(7) whether the operation of sensitive energy conditioner, the ball float level gauge and other work is stable.

(8) Units of noise and vibration.
