UPDATING AN EXISTING FRAME VALVE INTO A SUPPLY AIR WINDOW
With the Air-In® Chameleon, existing frame valves can be updated to supply air windows with heat recovery as follows:
The old valve is removed from the hole in the valve, T milling is carried out through the interspace and a thermal filter bar is installed in the external frame. A new plastic adjustment plate is placed in the hole of the existing frame, and the Chameleon valve is screwed in place (see installation pictures below).
An opening is made in the inside frame for the Chameleon valve (600 x 10 mm or 400 x 10 mm), and a Chameleon valve is screwed on the opening. A thermal filter bar is installed in the interspace.
As above, but instead of a filter bar, an opening is made in the external frame (600 x 10 mm or 400 x 10 mm), and an outer grille with a filter is screwed on the opening.
1. Remove the old valve from the opening in the frame. Measure the position of the opening and ensure the suitable valve type (Air-In® Chameleon 400 or Air-In® Chameleon 600) as well as the frame depth.
A T milling is carried out in the top frame of the interspace between the exterior and interior window glass (see pictures below
) in such a way that an opening is created in the existing horizontal opening (opening 400 x 12 mm or 600 x 12 mm). This way, two openings are available: A horizontal opening to the outside and an opening to the window interspace (T opening).
3. Two metal clips are attached to the external frame (distance 800 or 600 mm). The seal of the external window is only removed for the length of the filter bar (800 or 600 mm = filter length). Ensure that there is a gap of 3 to 4 mm between the window structure and the frame.
4. The filter bar clips to the metal clips of the frame with powerful magnets. Ensure that the seal above the filter bar is pressed tightly against the top frame.
5. The plastic adjustment damper is pushed into the opening in the frame. The damper acts as a summer/winter adjustment, air guide and silencer.
6. The Chameleon valve is screwed on the frame in such a way that the handle of the adjustment damper goes through the opening in the Chameleon. After initial installation, the valve can be removed from the base part without tools by pulling the valve towards the room.
