2.6 FITTING THE GRATINGS
(P7, P8,P9,P10)
To fit the external two gratings please proceed
as follows: familiarise yourself with the fitting of
the grating to the tube, before installation.
Insert the cords through the centre of the grating.
One grating fits on the outside of the tube and the
other fits inside. The air discharge is the bigger
hole and the grating therefore fits on the outside
of the air discharge tube.
Insert the supplied cord into the hole. Fold the
outer grating in half grasping the cord with your
free hand. Insert your arm inside the pipe with
the grating and push all the way to the outside.
Let the grating unfold and pull the cord toward
you. One grating fits on the outside of the tube
and the other fits inside. With a little patience
and manipulation the 2 gratings will fit the end
of the tubes. Grasping the cord, insert your
fingers between the fins and pull the grating
toward you until the same is properly slipped
in the pipe, keeping the fins in vertical position.
If the external grating is accessible to prevent
its removal, it is recommended to fasten it to the
wall with wall plugs and screws with a diameter
of 6 mm. Tighten the cord and fasten it to the
dent on the internal flanges.
