Atmospheric agents 怎麼翻呢?
For single temperature area operation, you must remove the black bottle
holder grill and replace it with the accessory grid (of the same kind of
the other wood color ones, already installed). We suggest you keep the
unused grid in a dry and cool place, in order to prevent it from being damaged by humidity or by other atmospheric agents, as this would make it unusable in the future.
