Masts
There are three main types of mast
configurations:
t
Guyed - generally required for mast
heights of over 3 m (10 ft) or for
climatic conditions where wind gusts
may exceed 160 km/h (100 mph).
Always consult with a local civil
engineer if in doubt. The mast is
anchored at the base and then guyed
using one or two guy sets, depending
on the mast height and configuration,
each with 3 lengths of non conductive
guying material.
t
Cantilevered - the lower third of the
mast is secured to a vertical surface
to provide support. These may also
require guying depending on mast
height.
t
Free-standing - base support only.
Ensure that the configurations and
heights for your specific installation
conform to the design and consultation
directives.
Specific advice for each mast configur-
ation is provided on pages 40 to 47.
When all of the components for the
ERITECH
® SYSTEM 3000 have been
received, they should be checked against
the design “Bill of Materials” and for any
possible shipping loss or damage.
Ensure the air terminal is supplied with the
finial tip secured in place. The air terminal
is supplied with three different finial tip
configurations (two separate, and one
secured in place), similar to that shown
in photo 1. It is important that the
correct finial tip is installed, specific
to the application. Photo 2 shows the
three different finial tip sizes, ranging from
sharp to blunt in dimension. The sharp tip
(middle), medium tip (left) and rounded tip
(right). The application of each of these tips
is detailed below:
t
Sharp Tip – Terminal heights less than
20 m (65 ft)
t
Medium Tip – Terminal heights less
than 50 m (165 ft), greater than 20 m
(65 ft)
t
Rounded Tip – Terminal heights greater
than 50 m (165 ft)
Note: heights listed refer to the actual terminal height above ground
level
If required, replace the finial tip supplied
with the appropriate tip for the application,
and tighten firmly.
Warning – Do not install the ERITECH ®
DYNASPHERE without installing the
correct finial tip.
1 – ERITECH DYNASPHERE with two spare finial tips.
2 – Three (3) ERITECH DYNASPHERE finial tip sizes.
