Assembly
Air Star Comfort 20/30
Work sequence for assembly recessed in wall
1. The ventilation unit must be mounted horizontally. Mark the dimensions on the wall.
Outer box dimensions are width: 290 and height: 340 mm. Add 10-15 mm for insulation.
2. Drill a hole with a diameter 12-15 mm in each corner. Check the wall studs and any
wires. Stagger the placement if necessary.
3. Cut with tiger saw. Deepen the recess to a depth suited to the wall structure. The outer
box depth is 204 mm. The maximum recommended recess depth is 180 mm.
4. Important! Calculate the holes for the outer box so that there is room for at least 30 mm
of insulation between the exterior wall and the back of the outer box.
5. Separate the ventilator from the outer box. Now slide the outer box into the opening and
align with a spirit level.
6. Mark the location of the Spiro pipe on the remaining exterior wall using a circular bushing
on the outer box’s back piece. Adapt the holes to suit the sleeve diameter and depth.
(Sleeve dimensions Ø 123 mm and 41 mm deep). The remainder of the holes are drilled
with Ø 100 mm + 10-15 mm of insulation around the Spiro pipe.
7. Now remove the outer box and drill the holes for the Spiro pipe.
8. Measure and cut the Spiro pipe to the correct length. Insert and fix the pipe in the proper
position, the black rubber seal on the pipe should be facing the outer box sleeve. Finish by
insulating around the pipe.
9. Installation of the outer box can be made with screw attachment or by fixing with sealing
foam.
10. Slide in the outer box and press the Spiro tube into the outer box sleeve. Make sure the
outer box is horizontal and vertical. Attach using a wooden wedge. At the screw attach
ments, drill attachment holes in the outer box at the locations corresponding to the wall
structure.
11. Screw or join the outer box to the wall so that it is secure. The screw attachment is always
used with vibration damping material between the outer box and the wall. Make sure
that the vibration damping material is not compressed too much and loses its function.
(Risk of structure-borne sound in the wall).
12. Insulate around the outer box, and finish by fitting the cover frame (option). Before the
assembly of the exterior wall grill, check that insulation has been placed around the pipe.
13. Clean the inside of the outer box before putting the ventilator in place. Carefully slide the
unit so that the ventilator sleeve goes into the slot on the outer box sleeve. Connect the
plug to the wall socket.
Comfort 20/30 is now installed and ready for operation. Go to chapter: Use for
setting the unit.
