3 -- INSTALLATION -- SAFETY

3.1 -- Safety instruction

The user is responsible for ensuring that all maintenance, inspection and installation work is carried out by authorized,
adequately qualified staff who are thoroughly familiar with this manual.
Any work on an actuator may only be performed after the deconnecting pneumatic energy supply.

ATTENTION

3.2 -- Inadmissible modes of operation

Operational safety and reliability of the actuator supplied is only warranted for its designated use as defined in the
type series booklet.
The limits stated in the technical documentations must not be exceeded under any circumstances.

3.3 -- Before any action

-- Index the mounting position of the actuator onto the valve (Position N o r M)

-- Index the position of the pointer 629 on mandrel 59--40

-- The disassembly of the actuator must be performed with be careful.

-- The device retrieval system stores mechanical energy (Cartridge springs 598.1 / 598.2), the dismantling of

this cartridge springs is strictly PROHIBITED.

-- If the maintenance of the spring cartridge (598.1 / 598.2) is necessary, it must be carried out by KSB Service.

: this actuator contains strong compressed springs. The dismantling of the actuator must be careful.
