for installation, it can be attached to the
terminated downconductor as shown in
the Upper Termination instructions
(IP found at www.erico.com).
Please note and record, the serial number of
each unit. The serial number is required for
any certificate of compliance upon request.
Masts
The selected mast configuration chosen must:
• Elevate the terminal to the required height
as determined by the design process
(minimum height of m ( ft.) above the
highest point of the structure)
• Include a minimum of m ( in.)
of insulated mast material (FRP)
immediately below the air terminal
• Be suitably rated for local weather
conditions. It is advisable that guidance
from a local civil engineer be sought
• Be securely attached to the selected
mounting point(s)
• Be guyed if applicable
nVent ERICO Dynasphere Terminal
The nVent ERICO Dynasphere is the air
terminal of the nVent ERICO System .
Suitable for use in:
• General purpose applications
• Temperatures of up to °C (°F)
• Corrosive environments
(salt or acid atmosphere)
Warning – Do not install the nVent ERICO
Dynasphere without installing the correct
finial tip.
Ensure the air terminal is supplied with
the finial tip secured in place. There are
three different finial tip configurations (two
separate, and one secured in place), similar
to that shown in Figure . It is important
that the correct finial tip is installed,
specific to the application height. Figure
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:
• Sharp Tip – Terminal heights less than
m ( ft.)
• Medium Tip – Terminal heights less than
m ( ft.), greater than m ( ft.)
• Rounded Tip – Terminal heights greater
than m ( 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.
Once the terminal has been checked and
found to be in an acceptable condition
