NOTICE
!
Risk of regulator damage due to excessively
high or low tightening torques.
Observe the specified torques on tightening
regulator components. Excessively tightened
torques lead to parts wearing out quicker.
Parts that are too loose may cause leakage.
Observe the specified tightening torques.
NOTICE
!
Make absolutely sure that no torque is
applied to the bellows seal (5.1) during
assembly or disassembly. Otherwise, the
metal bellows will be destroyed.
