There are two alternative ways to create a concrete foundation for
Ceilometer CL31. You can either cast a new concrete foundation or
use an existing one.
NOTE
If the tilt feature will be used (see section Using the Tilt Feature on
page 29), observe this in the layout of the foundation screws and
shield placement.
Creating a New Concrete Foundation
1.
Fasten the M10 × 40 wedge bolts to the lower ends of the
foundation screws (4 each).
2.
Fix a drilling template to the upper ends of the foundation
screws with nuts.
3.
Place the template with the attached foundation screws into the
hole in such a way that approximately 30 mm (1.25 inches) of
the foundation screw threads stand above the surface.
4.
Pour in the concrete and finish the foundation.
Using an Existing Foundation
1.
Drill four holes with a diameter of 12 mm and a depth of
165 mm (0.5 × 6.5 inches) into the concrete.
2.
Fasten the M10 × 40 wedge bolts to the lower ends of the
foundation screws (4 each).
3.
Place the wedge bolt and foundation screw combinations into
the holes, with the wedge bolts down, and hammer the
protruding threads down.
4.
Tighten the foundation screws a few turns to attach the wedge
bolts to the hole walls.
Mounting the Ceilometer CL31
Ceilometer CL31 is delivered with the measurement unit attached to
the shield. If two people are handling the installation, the shield can be
mounted with the measurement unit attached. It is, however,
recommended that you first remove the measurement unit, mount the
shield, and then reattach the measurement unit to the shield.
