1. Regardless of whether you open the inner or outer door of the glove box, you must ensure that the air pressure on both sides of the door is basically balanced, otherwise, it will either fail to open or “explosion” will occur. Similarly, when pumping and inflating the box, you must also ensure that the three-way valve is open (that is, to ensure that the air pressure inside and outside the glove is equal), otherwise, the glove will expand and burst.

2. If there is air leakage in the cabinet, first check whether the transition chamber door is closed tightly and whether the glove opening is damaged. If there is still air leakage, please check the “O” ring and vacuum rubber on the vacuum gauge seat, valve and two doors. The “O” ring on the antechamber door and the glove opening door should be replaced regularly (according to the frequency of use of the user).

3. When pumping the system, please slowly open the valve and pay attention to the changes of the gloves at any time. If there is expansion, the pumping speed should be slowed down. If the problem is still not solved, the pumping should be stopped. If the gloves burst, check 3-way valve whether the valve is open.
