Operation
while monitoring the pressure reading at the
gauge.
When a pressure gauge is not installed, ad-
just the set point using the adjustment dia-
gram Fig. 2.
To increase the set point, turn the set point
adjuster into the body (

) and out of the
body (

) to reduce it.
NOTICE!
Set point adjuster screwed too tight!
The regulator is blocked and the me-
dium flow through it is restricted. Pres -
sure regulation is no longer possible!
Only screw the set point adjuster up
to the point where the spring tension
can still be felt!
How to proceed:
1. Loosen the lock nut (11, size 17 mm) to
allow the set point adjuster to move free-
ly.
2. Determine the difference between the
fixed set point (Table 1) and the required
set point. Turn the set point adjuster (10)
the required amount of turns as specified
in Fig. 2 on page 10.
Based on the default setting, any subsequent
change to the set point can be also be made
by determining the required number of turns
using the specifications listed in Table 1.
3. Lock the setting with the lock nut (11).
