Model 408: If you have a newer instrument that has a regulator mount on the left
side panel, proceed to Step 2. Otherwise, a new left side panel with the correct
mounting holes will need to be requested from 2B Tech and installed. Remove all
of the screws around the enclosure front and back panels, including the screws on
the front bezel. Remove the left panel while keeping the top and bottom panels of
the instrument from sliding. Install the regulator mount on the left panel using the
two #10 pan head screws and split locking washer supplied with the Portable N
2
O
Source. Install the left panel on the instrument and install all of the screws at the
front and back panels of the enclosure.

2) Loosen the single #10 socket cap screw (see Figure 1) to allow the regulator
assembly to slide into the mount.
3) Slide the regulator assembly into the mount from the top. Position the regulator
assembly so that the mount is centered on the top part of the piercing device,
not the black cartridge cup (see Figure 4). Tighten the #10 socket cap screw to
secure the assembly in the mount.
