Setting of Opening Pressure

8.4.1 General

The opening pressure can only be set if a manometer is installed in the system
between the pump and the next shut-off valve or pressure retention valve.

!

WARNING

Settings on the overflow valve must only be carried out
by authorized specialists!

The opening pressure of the overflow valve is set in the factory to the maximum
pump back-pressure specified in the technical data. The opening pressure during
operation depends on various factors, e.g. the flow, the stroke frequency of the
pump, or the back-pressure. If an exact setting is required, the overflow valve must
be adapted to the local conditions.

The opening pressure must only be set to values below the maximum permissible
operating pressure.

!

WARNING

Danger of injury! Never set the opening pressure
higher than the maximum permissible operating
pressure of the dosing system and dosing pump.

!

WARNING

When dosing dangerous media, always refer to the
corresponding safety data sheets!
Wear protective clothing (goggles, gloves) when
working on the connections and lines!

8.4.2 Setting Instructions for Opening Pressure

Proceed as follows if the factory-set pressure is to be changed:

With the pump running

●

Remove the cap from the top part of the overflow valve.

●

Close the shut-off valve downstream of the manometer.

●

When overflowing of the dosing medium is heard, read the current opening
pressure on the manometer.

●

Using pointed pliers, rotate
-

in the clockwise direction to increase the pressure or

-

in the counterclockwise direction to reduce the pressure

until the desired opening pressure is set.

●

Open the shut-off valve downstream of the manometer.

●

Attach the cap again.
