19 READING OF THE INDOOR UNIT MANOMETERS
Each indoor unit is equipped with two manometers.
The differ ence between the manometers (1 and 2) reading can be used as approximate value
for verifying the water fl ow rate/pressure head when the unit works on the plant (so when the
3-way valve diverts the flo w to the l eft side on the line A).
To the differ ence of manometers value you should subtract the pressure drop of the 3-way
valve for ge tti ng an approximate value of the available pressure head of the plant.
The characteri stic curve corresponding to the Head pressure versus Water fl ow rate of the
three-way diverter valve, whose values should be deducted at the manometric readings for
verifying with suffici ent accuracy the available sta ti c pressure of the plant system at the
nominal opera ting points marked in the curves of Chapter 17.
It is recommended for safety to remove an additiona l 5% from the obtained values.
