Explosion-proof high and low temperature one machine manufacturer instructions installation point

After the explosion-proof high and low temperature integrated machine is delivered from the factory, it must be installed after reaching the destination. What should you pay attention to when installing?

The explosion-proof high and low temperature integrated unit arranges the distance of the air outlet more than two meters. If the surrounding air is found to be sultry, please install the exhaust fan to keep the air convection, so as to increase the service life of the explosion-proof high and low temperature integrated machine, and improve the foundation before the installation, and the surrounding air is smooth. To avoid corrosion pollution, places with less oil and gas. When installing outdoors, the shelter can be used for efficiency of explosion-proof high and low temperature integrated units. When installing, be careful not to damage the unit, and reasonably arrange the space around the explosion-proof high and low temperature integrated unit to facilitate the maintenance and protection of the unit. According to the cooling capacity, select the matching cooling tower. Install the pipeline of the explosion-proof high and low temperature integrated unit according to the pipe diameter. Do not reduce the diameter of the chilled water pipe, otherwise it will cause high voltage overload, affect the quality effect and increase the power consumption. 

After the installation of the pipeline connection of the explosion-proof high and low temperature integrated unit is completed, it is necessary to connect the power supply of the explosion-proof high and low temperature integrated unit. It is necessary to pay attention to the power supply of the explosion-proof high and low temperature integrated unit adopting three-phase three-wire or three-phase four-wire system, and the power line (RST) is connected to the power line. (N) Zero line, (D) Ground line. The main power supply of the unit is connected to the terminal block on the electric control box through the perforation on the electric control box to ensure the connection is tight. The power distribution requirements of the unit: main power supply voltage: within rated voltage ±10%; main power supply frequency: within ±2% of rated frequency. When the main power supply voltage fluctuates beyond the specified range, it is forbidden to start, otherwise it will cause serious damage to the unit. The explosion-proof high and low temperature integrated unit is equipped with various protection measures such as power overload protection and power supply protection, high and low voltage protection of the compressor exhaust end. ,

Explosion-proof high and low temperature integrated machine manufacturers reminded that during installation, it is necessary to take precautions during the handling process to avoid damage during handling, and it is necessary to pay attention to handling.
