Cold room light installation (pre-set machines only)
1.2.3
Install the cold room interior light (supplied) in a position that guarantees the best visibility inside the cold room. The tools required for
installation are as follows:
- screwdriver; - scissors; -drill.
• Fix the light fitting on the ceiling or wall of the cold room using the self-tapping screws provided "1" (fig. 1.2.3.a). If the light fitting is
being fitted to the cold room wall, ensure that the cable leads downwards, as shown.
• Remove the glass and protective grid from the light fitting by loosening the locking screw. Make a hole for the cable through the
stopper "3".
• Make a hole through the membrane of the cable gland "4" most suited to the installation type. Feed the cable marked "LC" (if it's
provided) from the machine through the stopper "3" and the cable gland "4". Pull out any excess cable (fig.1.2.3.b).
• Cut the cable down to size, remove the sheathing from the conductors and connect them to the relavant terminals of the light fitting.
Screw the stopper "3" to the cable gland and the light bulb (supplied) into the light fitting. Replace the light fitting glass and protection
grid.
