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).
internal exchanger water = 12/7°C
ATTENTION: IN CASE OF PREDOMINANT WINDS, WINDBREAK
BARRIERS ARE NECESSARY.
Water thermal head (min / max) are indicated in the section INTERNAL
EXCHANGER PRESSURE DROP
