10. TOTAL PRESSURE DROPS
The pressure drops include:
− EVAPORATORS
− HYDRAULIC CIRCUITS
The diagram pressure drops are
related to an average water tempera-
ture of 10 °C. The following table shows
the correction to apply to the pressure
drops when the average water tem-
perature varies
Depending on the size, NS can have
from 1 to 3 evaporators with tube core.
NOTE:
The water outlet probe (SUW) with its
trap is free, near the electrical box,
remember to insert it in the collector
of the outlet hydraulic parallel, using a
sleeve of ½ inch.
