Installing the regulator

1. Close the shut-off valves upstream and
downstream of the regulator while the
regulator is being installed.
2. Remove the protective caps from the
valve ports, if fitted, before installing the
valve.
3. Make sure that the correct gaskets are
used.
4. Bolt the pipe to the valve free of stress.
5. Open the shut-off valves slowly over a
time period of several minutes, prefera-
bly starting from the return flow pipe.
Î First start up the regulator after mounting
all parts.
Î Make sure that the restriction (8.5) is
open while filling the plant. Turn the set
point screw (8.3) counterclockwise ()
as far as it will go.
NOTICE
!
Risk of valve damage due to a sudden pres-
sure increase and resulting high flow veloci-
ties.
Slowly open the shut-off valve in the pipeline
starting from the return flow pipe side during
start-up.
