ABB SCK - Shutting Down the System

226 Operating instruction SCK Gas Sampling System OI/SCK-EN Rev. E
Shutting down the system
These instructions describe how to shut down the gas sampling probe. Note
that the cooling water should only be drained if the system is shut down for
prolonged periods or if it is subsequently disassembled. Otherwise the cool-
ing water can stay in the system.
Risk of injury in the area of the gas sampling system due to moving or fall-
ing parts, hot surfaces, hot cooling water, anti-freeze, compressed air,
lubricating oil
Wear general personal protective equipment:
 Closed overalls with long trousers and long sleeves
 Safety shoes
 Safety gloves suitable for mechanical work
 Safety glasses
 Protective helmet
 If necessary, additional protective equipment if prescribed by the opera-
tor.
danger of burning due to hot surfaces during and after operation of the gas
sampling system.
 Do not touch the gas sampling system during and after operation.
 Do not touch the gas sampling system until it has cooled down to 50 °C.
Specifically, do not touch
 the cooling module,
 the heated sample gas line,
 the connection box for the heated sample gas line on the retractor,
 the heated sampling filter,
 the entire gas sampling probe,
 the metal structure of the retractor,
 the shutter of the duct opening.
 If it is unavoidable to touch hot components, wear a face mask against
heat, heat-proof gloves and protective welder's clothing.
Danger of injury to skin and eyes in the event of contact with cooling water
or anti-freeze.
