CUTTING THE CEILING FINISH

When the window has been installed, ad-

just the hole in the ceiling ﬁnish to its ﬁnal

dimensions. If using a VELUX lining, adjust

the hole by means of the template supplied

with the lining that ensures horizontal lining

at the top and vertical lining at the bottom.

This principle also applies to on-site linings.

ELECTRICAL OPERATION

Before ﬁtting the interior lining ﬁnish, it

is recommended to ﬁt a cable to prepare

for subsequent installation of electrical

products where necessary.

Run the cable through the pre-drilled hole

in the top frame. Fasten approx 20 cm of

the cable as shown. The rest of the cable

can now be led hidden to a position suitable

for subsequent connection to a control unit.

For cables up to 40 m, use eg a cable with

dimensions 2 x 1,5 mm

Note! Electrical operation of top-hung win-

dows requires a dierent wiring procedure.

Please contact VELUX.

INSULATION AROUND THE WINDOW

Correct insulation around the window is

important to avoid thermal bridges. Instal-

lation set BDX ensures the necessary frame

insulation. Use the wedge-shaped foam

gaskets supplied to close possible gaps

between frame and rafter.

If the installation set is not used, provide

corresponding insulation around the frame

up to the upper side of battens.
