Automatic Weather Station with UT20/UT30 Tower
1-4
1.4 Site Preparation
You are recommended to take a full tool set of metric and imperial spanners on
site. Minimum requirements are given in the following sections.
Always take sensible precautions during installation of any
metalwork. We recommend that you use industrial quality
gloves and protective footwear to minimise the possibility of
minor injuries.
1.5 Base Installation
Choose the location of your tower base carefully, remembering that you will need
sufficient space to assemble the tower on the ground before attaching it to the
hinged base and ‘walking’ it into its upright position.
The base sections for the UT20 and UT30 differ slightly in design – the UT30 uses
three separate legs, whereas the UT20 base is an integrated assembly. The
following instructions generally illustrate the UT30 base, but the UT20 base is
fitted in a similar way.
If you will be using the optional guy rope assembly, you will also need to consider
the positions of the guy anchors – please refer to Section 1.6, below.
NEVER place any
aluminium
tower section directly into a
concrete base. The corrosive effects of the concrete on
aluminium will damage the tower and void the warranty. Use
only the steel base/leg assemblies as shown below. You must
also ensure good water drainage for the aluminium tubing on
all the tower sections to minimise the possibility of trapped
water freezing (and possibly causing splits in the tubing). The
supplied bases allow for adequate drainage; you must ensure
that the bottom openings of the aluminium tubes do not
become blocked.
(The
steel
legs can, however, be suitably treated to prevent
water ingress and to minimise rusting.)
1.5.1 Base Installation
For a base installation you will need:
A shovel
A pickaxe
A spirit level
A 4 metre tape measure
A hammer
A concrete trowel
Two 9/16" open-ended spanners
Locate where the tower base is to be installed and place the tower sections end to
end in the correct order of assembly. Make sure enough clearance exists so that the
tower can later be ‘walked’ up to its upright position without overhead
interference.
