Operating environment  

·      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;

• Elevation should not be more than 1000 meters above sea level, otherwise should lower ratings to use;
• Ambient temperature should not be higher than 104°F, lower than 14°F
• Relative humidity should not be more than 85%;
• No severe vibration, no conductive dust, no corrosive gas and explosive gases;
• Installation inclination should not more than 5 degrees;
• Installed in a well-ventilated place.

Circulation soft water-cooling system technical characteristics 

• Closed loop cooling: avoid anything to block the pipeline
• Soft water cycle: No limescale deposit, otherwise can cause the damage of pipeline water cooling components, water cooled condenser, water cooled reactor, etc.
• The system is energy saving, easy to operate and high thermal efficiency.
• 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.

Requirements of power system 

• Power voltage shall be the sine wave, harmonic distortion is not be greater than 5%
• Imbalance between three-phases should be less than ±5%
• 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)
