NOTE
When the nitrogen generator is turned on for the first time or after a prolonged shutdown period, it is
likely that the Product Receiver is full of air. Product purity can be increased by purging the Product
Receiver to safe area / outside the building for approximately 15 minutes before using the product.
7.1.2
Normal Start-Up
Follow this procedure to start the generator for normal operation. If this is the first time the unit has been
started, follow the Initial Startup procedure,
1.
Open the air isolation valve.
2.
Turn on the Main Power switch
3.
Open any shut off valves in the product nitrogen line to the user’s piping system. Allow the system purity
to rise before using product.
NOTE
If the generator or any part of the system has been opened to the atmosphere, the system must be
purged of any residual air.
7.2
Shutdown
This section describes how to perform both an emergency shutdown and a normal shutdown.
7.2.1
Emergency Shutdown
In case of an emergency, simply
turn the Main Power Switch to OFF
.
This will stop all generator functions
immediately. Nitrogen supply can be shut off manually closing the nitrogen product ball valve located on the
product receiver tank.
7.2.2
Normal Shutdown
This procedure allows the generator to be restarted more quickly than execution of an emergency or abnormal
shutdown procedure would.
Touch the digital power switch on the Main Screen in the top left corner (
). Proceed to valving off
the nitrogen process valve after the nitrogen storage tank.
**WARNING**
The generator will remain pressurized after shut down. Before performing any maintenance or opening
any piping systems, always depressurize the system. Failure to do so may result in injuries.
