Installation Installation location requirements Work fields Unit location Verifying clearances (clearance area) 3.1 Installation location requirements The installation place must be chosen as specified in standard EN 378-1 and the requirements of standard EN 378-3. In any case, the installation site must consider the risks associated with an accidental leak of refrigerant gas contained in the direct expansion units. - Page 12 3.3.1 Noise 3.3.2 Windy areas (Resting on the ground) Wind can affect the operating conditions. Minimise the effects by: • Placing the unit with the long side parallel to the direction of the main winds. During operation, the unit generates noise. Avoid placing it with the coil perpendicular to the direction of the main wind.
