O Source and mounting hardware.
To install the Portable N
2
O Source follow the following steps:
1) If there is no regulator mount on the instrument, first install the mount.
Model 211: If you have a newer instrument that has a regulator mount on the back
panel, proceed to Step 2. Otherwise, a new back panel will need to be requested
from 2B Tech and installed. Remove the top and bottom cover first and disconnect
all connections to the back panel. Taking a photo of the connections to the back
panel is a good idea to help ensure that the connections are remade correctly after
installation of a new back panel. Transfer all the components on the old back
panel to the new one. Mount the regulator mount to the back panel using the two
#10 pan head screws and split locking washers supplied with the Portable N
2
O
Source. Install the back panel on the instrument and install the top and bottom
panels.
