3. The power cord should not be wrapped around metal objects, and should not be placed in a low temperature or humid center to avoid leakage of rubber due to aging.
4. Don't overcrowd the items in the box, leave a space for natural convection of the atmosphere, so that the humid atmosphere can slow down and escape on the wind roof.

If so, use a fine gauze cloth to smooth the contacts before using them, and always wipe them with a clean cloth to make the contact good (note that it is necessary cut the power supply). Do not hit the metal pipes of the indoor temperature regulator so as to affect its flexibility.
