Nitrogen Gas Piping <Removal>
(1) Before removal of the nitrogen gas pipes, close the feed valve of
nitrogen gas.
(2) The pipe on the device side has residual pressure. Install a pressure
gauge in the nitrogen supply source of the device (on the way to the
pump in the pipe) and check that the pressure decreases down to the
atmospheric pressure, before removing the nitrogen gas pipes. If the
inner pressure is high during the work, there is a risk that the pipes
may be disconnected with force and you may get injured.
Intake and exhaust piping <Removal>
(1)
Remove
according to the installation manual of the device.
(2)
For
a while after the operation stops, do not touch the intake and
exhaust pipes since they are subjected to high temperature.
Remove after the pump temperature becomes low.
(3)
Fully
seal the intake and exhaust ports using shutoff flanges etc.
