Before the box was opened, the inspection groups formal air treatment units packaging unit was complete and non -damaged, whether the nameplate parameters of the names met the requirements, and whether each attachment was complete.
2. In the full air system of the combined air processing unit, the air sent into various districts in various districts is concentrated in the computer room.This device that is treated with air is called a combined air treatment unit, or an air -conditioning unit.During the transportation, inspectors should inspect whether the air treatment unit has deformed or damaged, whether the fastener falls off, and check the components of the fan.If abnormal situations are found, wait for repair before use.
3. Use the 500V meter table to measure the insulation resistance between the shell and the motor of the air treatment unit of the air treatment unit, and its value should be greater than 0.5 mega Euros.If the resistance value does not meet the requirements, the motor winding should be carried out for drying.The temperature during drying should not exceed 120 ° C.
4. Prepare the various materials, tools and venues required for the fresh air system settings.
5. The installation process of a combined air treatment unit must have a safe device to prevent accidents and install and wiring by those familiar with relevant safety requirements.
6. The air ducts that connect to the port and export of the combined air treatment unit shall be supported by separate support, and the pipeline weight shall be superimposed on the component of the fan.When installing the fan, pay attention to the position of the fan, adjust the relay of the integration surface of the fan and the foundation and the air outlet pipeline, so that it can meet the requirements and not forcibly dock.
7. After the installation of the combined air treatment unit is installed, use the hand or leverage to vibrate the impeller to check whether there is an excessive or rubbing condition, and whether there is an obstacle that affects the rotation.If there is no abnormal phenomenon, trial movement can be performed.The exposure part of the fan transmission device should be installed with a protective cover (self -provided by the user).If the air inlet of the fan does not connect to the pipeline, it also needs to add a protective net (providing protection, anti -theft, anti -pendant) or other installation devices.
8. The power control box of a combined air treatment unit must match the fan (referring to power, voltage, pneumatic pipeline, and master form, etc.).
9. The clean air is sent to the cooler or heater through the fans of the condensed exhaust heat recovery unit for cooling or heating to achieve a comfortable level and then send it to the room.The wiring of a combined air processing unit should be carried out by professional electricians, and the wiring must be correct and reliable.Especially the wiring number at the electrical control box must be consistent with the number on the fan wiring column.The fan shell should be reliable, ground must be reliable, and zero can be used instead of grounding.
10. The clean air is sent to the cooler or heater through the fan of the condensed exhaust heat recovery unit for cooling or heating to achieve a comfortable level, and then send it to the room.After the fans of the combined air treatment unit are installed, check whether there are residual tools or items in the fan.
The above is about preparation before installation of a combined air -conditioning unit
