Mounting instruction OA 13 A

WARNINGS
We strongly encourage you to read this manual before installation and use
of the product and strictly observe the recommendation hereof.
Installation shall be carried out by qualied personnel. Mounting in-
struction has to be carefully observed.
For installation and use, please observe all specic regulation and
laws applicable in the destination country.
Carefully read all safety regulations. Failure to observe the indica-
tions reported, can cause serious damages to third parties.
If not otherwise indicated, for tightening of screws, bolts and in gen-
eral threaded rods, refer to applicable gures reported in Tab. 2 in the
paragraph General Installation Instructions for GIBERTINI Antennas
Gibertini srl reserve the right to change specications to products and to documentations without prior notice.
NOTES ABOUT DISPOSAL
The barred bin symbol indicates that the product must be disposed of separately from other waste
and cannot be thrown into the domestic waste at the end of its life. The user will therefore take the
appliance at the end of its life to the suitable separated collection centres for metal parts waste in
their own town. An adequate separated collection for sending of the appliance to recycling, treat-
ment and environmentally compatible disposal helps to avoid possible negative effects on the environment
and on health thus favouring the reuse and recycle of the materials of which the appliance is made of. The
unauthorised disposal of the product by the user causes the application of administrative fees provided for
by the regulation in force.

SIDE RODS OPTION
Fix the side roads to the monopod [A] and turn
them until they touch the edge of the reector.
Drill (bit size 7) the edge of the reector corre-
sponding to the hole of the rod [B].
Assemble with the screws supplied.

ASSEMBLING STEPS
qAssembly of the pole clamp unit
A xing pole with a diameter from 75mm up to
90mm and thickness of 3mm is highly recom-
mended.
wAssembly of the antenna rear
bracket to the pole clamp unit

The graduated scale for elevation can be used
for coarse pointing help, because the scale in-
dication can be affected from errors (roof-pole
perpendicularity for example). The ne regu-
lation of the elevation pointing for optimized
performances is left to the installer.
ASSEMBLING STEPS
eAssembly of arms and feed holder assy
rAssembly of the antenna reflector
on the bracket assy.
Fine elevation pointing can be easily done us-
ing the threaded tie-rod.

Installation
All WISI Antennas are manufactured using well certified materials and assembly components that
ensure a reliable and long life product.
During installation, for proper use and safety, screws and bolts have to be used in proper indicated
place without exchange in position (e.g. do not use a M4 bolt where an M6 is foreseen).
The personnel in charge of installation will be the sole responsible of the pole fixation on roof or wall,
and have to take care of the proper tightening between antenna components. If not elsewhere indi-
cated, the following table report the recommended tightening torque, in Newton * meter, to be applied
on different mechanical couplings.

Maintenance Plan
Antennas have shown good durability even in worst conditions, provided that no perma-nent
damages to plating or painting have been procured during the installation or due to other origins
after installation.
Nevertheless, a periodic maintenance enforce the warranty validity and help in order to elongate the
life of the assembly.
Period Every two years or in case of storm wind and/or strong hailstorm
General care Verify the integrity of the antenna assembly.
Clean with a conventional duster the dish surface and the LNB feed -do not use solvents
for normal cleaning- dry cleaning is normally enough, use water or alcohol to remove
solid attached elements, dry with a cloth.
Paint If the painting has been ruined, remove gently the rust, if present, using a fine abrasive
paper (type 00), then clean with acetone, chloroform or similar oil free solvent, dry and
than repaint with two pass of -water based- opaque paint of the proper RAL. (Conven-
tional paint used in car repair. Please refer to the paint Manufacturer recommendations
for the latency time between the painting).
Chemical solvents are flammable and volatile : do not expose directly, protect with mask and gloves.
Use only opaque paints. Brilliant paints can over heat the LNB “cooking” it with permanent damages.
Zinc plating If damaged due to environmental corrosion, zinc plating can be restored with a chemical
zinc spray (ZINK TK0105 by TEKNICA -Italy- or similar products from other Manufacturers
like TALKEN, etc.). Using a metallic brush remove oxidation and rust if present, clean with
acetone, chloroform or similar oil free solvent and live it to dry. Apply one or two pass of
spray zinc, having care to cover uniformly all the exposed surfaces (this apply specifically
the clamp brackets). Carefully follow the indications of the spray zinc Manufacturer.
The spray contain Toluene: flammable, do not expose to fire, do not smoke, do not dry with direct
flame or hot air irons at temperature higher than 80°C. Vapors can cause irritation and narcotic
effects, protect with mask and gloves.
