Do not commence tuner installation if you do not have a secure lightning protection
grounding system as per Section
Do not use grounding systems that are not built to regulations - this may lead to fire, gas
explosion, other incidents, or death, including that of other persons. Never use the tuner,
unless it is properly grounded!
Do not mount the tuner in a position that will put it under water at any time.
Do not mount the tuner in a place that will allow sprinklers or water hoses to spray the
weather seals or connectors.
When mounting in the open, never install the tuner in a slanted position neither with
protection cover down, to avoid contaminating the inside of the assembly, and to prevent
precipitation from seeping into it. This may cause damage that is not covered by the
warranty!
Do not try to additional weather sealing to the tuner. It should be installed in an airy
location in order to cool down during operation and to dry up after rain or morning dew!
Before commencing tuner installation, carefully consider and map out the way the coaxial
cables run from the amplifier to the tuner and from the tuner to the antennas, as well as
the manner in which they will enter the shack.
At first, lay out the cables along the route to the radio station and antennas, and protect them from
mechanical damage, in case they move in the wind, snow or ice. When the end of the cable is inserted in the
foundation of the building, take precautions to seal against wetting the connecting terminals, main grounding
plate of the building (see Point
sufficient U-shaped slack before cable insertion to facilitate water drip off.
The tuner should be mounted strictly horizontally, with the connectors facing downwards and at a height of
no less than 1 m above base level (ground or roof).
The installation height above the base is essential in order to install cables with a sufficient U-shaped slack
under the tuner bottom level, so that any rain, dew and other precipitation or sprays reflected from base will
not wet the tuner and will safely drip off.
Also, in the case of heavy snowfall, the snow will not reach the tuner connectors.
