Adequate service space must be reserved for safe maintenance and checks. The installation site must be away from salty air (coastal areas), sulfide gas (hot springs), oil, steam, corrosive gas, and metal dust, as these can damage the unit or create a fire hazard. When installing multiple outdoor units in a modular configuration, they must be spaced at least 20 mm apart.
