Eight,Operating conditions

1.Start-up voltage:187V~264V

Running voltage:198V~264V

2,The period of the turning down and restarting the compressor should be more than 3 minutes.

3,When the compressor has been installed into the refrigerating system, it should be perpendicular to the leveling floor with max inclination no more than 5°.

4,The residual moisture in the refrigerating system (not include compressor) should not exceed 60ppm, the residual impurity in the refrigerating system (not include compressor) should not exceed 20 mg.

5,The filling amount of refrigerant should not exceed 1100g.

6,When the terminal cover is installed, the nut screw moment is 1~1.5N.m.

7,The pipe and hermetic pens attached to the compressor should not be bent..

8,The compressor should never be operated while under vacuum; otherwise, internal arcing can cause damaging parts.

9,The compressor should not be operated to form a vacuum and to adsorb air.

10,The compressor should not be left opend in the atmosphere for more than 15minutes.

11,The electric pulse should not be applied to the hermetic terminals when the compressor is under vacuum.

12,The compressor should be kept in the clean place with low-moisture.

13,The compressor must not be applied for transportation equipment, such as automobiles, trains, ships, and others.

14,The compressor should not be splashed with water intentionally.

15,Refrigerant should be charged from the end of condenser of refrigerating systems. Never charge refrigerant to the compressor directly.

16,Temperatures within systems during stable compressor operation should not be less than -35°C to prevent wax precipitation from the oil.

17,The lead wires should be connected to hermetic terminals without being touched on the surface of the compressor.

18,The compressor must be used according to the requirement of the specification.
