K3.1.142e Manual NitroFlow Lab - 38 -
7 Operation
7.1 Commisioning NitroFlow
®
Lab
1. Make sure that the connections are correct and fixed properly.
2. Switch on the NitroFlow
®
Lab with the switch at the back of the
generator (refer to §3.3).
3. Then touch the ON/OFF button
on the touch screen display in
the front of the generator.
CAUTION
Don’t use sharp objects to operate the screen.
4. It will take about 3 minutes before the NitroFlow
®
Lab will start to
run. The countdown in seconds is shown on the display.
IMPORTANT
The NitroFlow
®
Lab must be run with sheet metal covers
mounted on the unit; not doing so will affect the heat
management of the system and shut down the
compressors; prolonged running without sheet metal
covers will shorten the life of the appliance and can lead
to irreparable damage
5. Check the inlet pressure level in the maintenance
-menu (screen
3/5); in case this exceeds a level of 4.5 bar(g), the unit must be
switched off and checked for blockades on the outlet. When a
cause cannot be found, stop running the system and contact your
supplier.
6. Check whether the connections of the tubing between the
NitroFlow
®
Lab and the application are free of leaks.
7. When the outlet is blocked the delivery pressure must not be higher
than 8 bar(g); the excess nitrogen is vented via an internal
pressure relief valve or the unit is switched off in case of no
nitrogen demand.
