Warning: the still air condition is meant as absence of air flow to 
the unit. Any wind condition can let air pass through the 
condenser coil thus worsening the operating limits of the unit (see 
limits with air speed at 0,5 m/s & 1 m/s). 
ATTENTION: IN CASE OF PREDOMINANT WINDS, 
WINDBREAK BARRIERS ARE NECESSARY. 
Water thermal head (min / max) are indicated in the section

Notes: 

Measures according to ISO 3744 regulations, 
with respect to the EUROVENT 8/1 
certification. 
the sound levels refer to the unit at full load, in 
the rated test conditions. 
The sound pressure level refers to a distance 
of 1m from the external surface of the 
units operating in an open field.
