CHANGING DISPLAY UNITS
Warning: Ensure the NTO-200 is relieved of
pressure before changing units.
The membrane cartridge must be removed from grip before changes can
be made to the setup. Unscrew locking ring from the grip and remove
the cartridge. (Note: This will create error message E4 when grip is
powered up. It will clear itself when the NTO-200 is reassembled.)
Press and hold ON/OFF button until desired units (bar/psi/MPa) are
shown on the display. Release button to save the new unit setting and
turn off NTO-200. (Note: If you scroll through all the units back to
current setting, the NTO-200 will automatically shut down.)
RESETTING ZERO POINT
To reset the zero point of the NTO-200, unscrew locking ring and remove
cartridge. Press ON/OFF button, the NTO-200 will power up and will
reset the zero point. After this is complete, it will automatically shut
down.
SETTING UP AIR SUPPLY
Before performing Nitrogen fills with the NTO-200, customer must first
set up the compressor to supply the NTO-200 with clean, dry (oil less
and waterless) air. To do this effectively, RTI Technologies has supplied
a filter with ¼” NPT ports to install in air supply.
When installing the filter, mount so the automatic drain is pointing
downwards. This drain will automatically bleed any fluids that collect in
the bowl when it detects a certain amount present.
After the filter is installed, the customer should take the ¼ BSPP x ¼
NPT fitting (Item 10 on previous page) and install it on the back side of
the NTO-200 grip, (Item 1 on previous page). NOTE: The customer
must also provide the hose that connects the filter to the NTO-200
grip assembly.
