4 MINIMUM TECHNICAL SPACES
For all units, it is fundamental to respect the minimum distances in order to guarantee optimal ventilation to the nned heat exchanger coils to avoid the following:
— The generation of hazardous atmospheres in the case of refrigerant gas leaks;
— Return of hot air;
— Insucient air ow to the nned heat exchanger coils.
Each side of the unit must have space to allow all routine and extraordinary maintenance to be performed.
The air suction inlet and the vertical air exhaust must not be obstructed.
The following images indicate the minimum required space:
