3.4.3 Inlet
Installation
Slide the inlet tube into the roof jack, then into the Sampler Module. Open the door to the Module and
guide the inlet tube into the Tee until it is past the O-ring and seated on the stop inside the Tee. Slide the
roof jack mate onto the tube into contact with the roof jack creating a weather proof seal.
The roof jack assembly should look like the right figure below.
Tighten the lock ring at the top of the Sampler Module by hand until it is secure around the inlet tube.
This keeps melting snow and wind blown precipitation out of the Sampler Module.

Support Feet Installation
The mounting feet are installed in the wrong direction to allow for easier shipping. The figure below on
the left shows how the feet are installed when you receive the stand. You will have to remove the support
feet and install them correctly before operating the URG-3000N
Remove the (2) S.S. screws that hold the feet onto the base and re-install them with the larger flat surface
facing down onto the ground like shown in the figure below on the right. There are (4) hole in the part of
the feet that face the ground. The (2) larger holes are to allow the stand to be bolted to a sampling
platform.
