• The builder will make the holes in the brick as precisely as possible so as not to complicate later plastering work.

• Choose the most appropriate spotlight diameter and cut the box along the marked fracture lines.

• Completely remove the box support which is not necessary in this type of installation.

• Possibly, though not necessarily, open a fewof the ventilation holes on the box cover, to favour heat dispersion through the cavities in the mounting surface.

• Insert the box in the applicator and turn the pin to block it

• Position the tripod on the box and tighten the knob

• Using a common extensible pole for paint-rollers, or a builder’s sprung perch or, even better, three provisional plugs in the slots, hold the assembly against the unplastered ceiling and keep it steady.

• The special configuration of the application system enables you to achieve a fast and precise positioning of the box at exactly 1 cm. from the brick, leaving enough space for the subsequent plastering.
• The use of more than one application system at the same time is reccomended.

• Fix the box using polyurethane foam or quick-dry cement mortar, allow to dry before removing the application system, which can be re-used hundreds of times.

• Use polyurethane foam in small quantities. And it is advisable to apply it using the correct gun.

• The builder, who has previously made the hole in the brick, will then fill-in around the box before adding the final plaster.
