9. 1 .2 Minimum water content
KEY
(1) Minimum water content for air
conditioning applications
(2) Minimum water content in the
case of process applications or
applications with low outside
temperatures and low load.
The pressure drops of the diagrams
are relative to the average water
temperature 10 °C. The following
table shows the correction to apply to
the pressure drop when the average
water temperature varies.
NOTE
For all models the plumbing parallel is
the responsability of the installer.
