INSTRUCTION MANUAL FOR USE, INSTALLATION AND MAINTENANCE
It is also provided with two suitable slots, in opposite position, to make easy the
fixture removal by using two suitable lifting tools (available on request, P/N 332.4140
or 332.4230). As alternative, two screwdrivers can be used.
A silicone O-Ring (separately supplied) has to be mounted outside around the dome,

Optical Assembly
The optical assembly consists of four prisms (Figure 5 - n°13) with relevant gaskets
(Figure 5 - n°12) kept into the proper position by mounting plate (Figure 5 - n°15) and
four LED modules (Figure 5 - n°7) with reflector (Figure 5 - n°6). Unidirectional
fixtures mount only two prisms and two LED modules.
Each LED module consists of six LEDs mounted on a metal core PCB, coupled with the
support through thermo conductive material; the reflector is fixed to the support
assembly.
All the optical assembly parts are factory assembled; they may be field-replaced if
necessary.
