B.  operating environment

 

   2.1、 Indoor installation, equipment grounding is good, the ground color with a significant  

       difference between control wire (ground wire is yellow green) as its cross-sectional 

       area > 4 mm², grounding resistance is greater than 4 Ω;

   2.2、 Elevation should not be more than 1000 meters above sea level, otherwise should lower  

  ratings to use;

   2.3、 Ambient temperature should not be higher than 104°F, lower than 14°F

   2.4、Relative humidity should not be more than 85%;

   2.5、No severe vibration, no conductive dust, no corrosive gas and explosive gases;

   2.6、Installation inclination should not more than 5 degrees;

   2.7、 Installed in a well-ventilated places.

 

C. Circulation soft water cooling system technical characteristics

 

   3.1、 Closed loop cooling:avoid anything to block the pipeline

   3.2、 Soft water cycle: No limescale deposit.otherwise can cause the damage of

        pipeline,water cooling components, water cooled condenser, water cooled reactor,etc.

   3.3、The system is energy saving, easy to operate and high  thermal efficiency.

   3.4、Once only need soft water consumption of small, add soft water(distilled water),

   is filled only once. Antifreeze solution can be added in the winter time.

 

D.  Requirements of power system

  

   4.1、 Power  voltage shall be the sine wave, harmonic distortion is not be greater than 5%

   4.2、Imbalance between three-phases should be less than ±5%

   4.3、Power voltage fluctuation should not be more than ±10%, and the frequency variation

    is not more than +/- 3%(should be between 49 to 51 hz)
