34 Installation
Before
starting
the installation,
there some important
things to remember
about
installing the system.
First, never mount the dish on a surface that is not structurally
sound.
Excessive movement of the mounting
surface will reduce the performance
of
the system.
Second, whenever drilling holes in a home, follow the old rule of measure
twice and drill once. Drilling a hole in the wrong place can be difficult and costly to
repair.
Finally, read and follow all the safety instructions
at the start of this manual.
These warnings are for both you and your customer's
safety.
Leveling Basics
One of the key steps of the installation
is leveling the mast. When mounting the foot
and mast on any surface, the mast must be level both horizontally
and vertically.
If the
mast is not level, alignment of the dish becomes difficult without the help of special
sighting equipment.
Figure 21 is the mast and foot assembly. This assembly can mount on either a horizontal
or vertical surface by adjusting the position of the mast on the foot. This is the only
adjustment
on the foot. Therefore, the position of the foot on a horizontal or vertical
surface is important.
Whenever positioning
the foot on a nonlevel surface, orient the
foot's adjustment in the direction of the pitch. This simplifies the leveling procedure and
prevents the need of spacers to level the mast.
