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 (5-10 in Hg), 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 3010P Gas Connector panel. The inlets for

zero and span gas are included only with the –C option.

The unit is manufactured with

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

turn beyond finger-tight.)

2. Hold the fitting body steady with a backup wrench, and with

another wrench rotate the nut another 1

turns.
