GREE air conditioner copper valve cap can not be installed, okay?
No, it doesn't make much difference, and it won't have much impact on usage. In principle, some will be installed.
Temporarily does not affect the operation, but will affect the valve, it will be contaminated, the next can not be opened and closed properly. The best thing to do is to match one.
Air conditioning copper valve cap can not be installed, it will not affect the work, but the role of air conditioning copper valve cap is to prevent water, gas, mud, debris and other pollution, and let you next to use when it may be twisted, can not open. I suggest you buy one and put it on!
