Precautions for installation and use
7.1 Check whether the air cooling facilities are good before reactor operation;
7.2 Before operation of the reactor, check the connection bolts, whether the mounting bolts are tight, and whether there are foreign objects on the reactor;
7.3 During the reactor maintenance, it is forbidden to change the core air gap and winding position;
7.4 Reactor core and metal structural parts should be reliably connected to the ground.
