18 MINIMUM TECHNICAL SPACES
For all units, it is fundamental to respect the minimum distances in order to guar-
antee optimal ventilation to the finned heat exchanger coils to avoid the following:
— The generation of hazardous atmospheres in the case of refrigerant gas leaks;
— Return of hot air;
— Insufficient air flow to the finned heat exchanger coils.
Each side of the unit must have space to allow all routine and extraor-
dinary maintenance to be performed.
The air suction inlet and the vertical air exhaust must not be obstruct-
ed.
