For pressurized service, use the restrictor without the blue dot and union
from the restrictor kit and attach it to the Sample In port. The small circular
orifice should face away from the back of the unit (against the direction of
gas flow). Use the restrictor without the blue dot sticker in the same manner
for low pressure applications (less than 5 psig).
For vacuum service, use the restrictor without the blue dot sticker and
union but attach it to the Exhaust Out port. The small circular orifice should
face toward the back of the unit (against the direction of gas flow).
Remove the blue sticker from the restrictor before using.
WARNING: Operating the unit without restrictors can cause
damage to the micro-fuel cell.
Figure 3-2 shows the Model 3010T Gas Connector panel. There are
inlets for zero, sample and span gas input, and an outlet for exhaust gasses.

The unit is manufactured with 1 / 4 inch tube fittings, and 6 mm adapters
are supplied for metric system installations. For a safe connection:
1. Insert the tube into the tube fitting, and finger-tighten the nut until
the tubing cannot be rotated freely, by hand, in the fitting. (This
may require an additional
1 / 8 turn beyond finger-tight.)
