3.6.1
Installing non-retractable sender/receiver units
Non-retractable sender/receiver units can be installed/removed on the nozzles if plant is
out of operation only. The gas pipeline must be free of any gas/liquid with hazard potential
(toxic or aggressive).
Assembly
●
Place gasket on the nozzle connection. Consider sealing instructions in chapter 6.5.
●
Carefully insert the sender/receiver unit into the nozzle to stop and screw on with
fastening screws.
●
Check process connection for tightness.
3.6.2
Installing retractable sender/receiver units
Retractable sender/receiver units can be installed/removed on the fitting set with
observation of the following information while the plant is in operation.
NOTICE:
●
Process ball valve 2”/3” (5 in
→
p. 99, Fig. 46
) is closing the nozzle and pre-
vents that process gas can escape from the pipeline.
●
Process ball valve 2”/3” may be opened only if the sender/receiver unit is
mounted tightly. Venting connection must be closed tightly with blind screw.
Tightness has to be checked by the user.
●
Do not dismount sender/receiver unit as long as process ball valve 2”/3” is
not closed tightly.
●
Retractable sender/receiver units can be equipped with venting valve
(option). Do not open venting valve if process ball valve 2”/3” is opened!
●
The process ball valve 2”/3” has a non-symmetric design. The short tube
side must be connected to the nozzle, the sender/receiver unit must be
connected to the long tube side (
●
Flange gaskets must be replaced at every assembling/disassembling of
ball valve and sender/receiver unit.
WARNING:
The gas in the pipeline can be dangerous.
Observe and follow the valid regulations and safety regulations as well as
the safety notices in Section 1.
Take special precautions for use in plants with increased hazard potential
(toxic/aggressive/explosive gases, higher pressure, higher temperature)
(risk or serious injuries).
Use suitable protection measures against possible local hazards or hazards
arising from the equipment.
Make sure the 2"/3" ball valve (5 in
) is closed.
Observe the permitted operating parameters according to the Figures in
during all work.
Venting of any gas with hazard potential (toxic, aggressive, explosive etc.)
requires always suitable protective measures and safety precautions for
safe venting and is in the responsibility of the plant operator (
