 2-2 Installation Requirements
- Make sure to have enough space at least 60cm from the rear of set, when a
support structure is installed on the floor, to accommodate a worker and a tool,
for a example, ladder, etc. When the height of a structure is too high, Samsung
recommend to install ' Cat Walk' at the rear of set and a lift in the front of set so
that workers can work easily in a high area.
