K-factor setting
You can easily set the required k-factor with the help of
the knob located on the short side opposite the short side
with water connections.
Example: To achieve the required flow of 25 l/s at
100 Pa, requires k-factor 2.5
A
:
Find the product’s length and air connection diameter
from left-hand side of the k-factor table.
B
:
Read the required k-factor on the row in question.
C
:
Follow the vertical row and read the number of degrees
at the bottom.
D
:
Loosen the screw located in the knob’s groove (the
knob then moves to the fully open position, 90°) Turn
the knob until the marking “D” reaches the required
number of degrees.
E
:
In the example from the table for a PARASOL Zenith
with length 1200, ø125, k-factor 2.5, turn the knob to 44°.
The right to design changes is reserved.
