v1.2 2
1. Extract the AHU out of the casing
Put the unit on its side on a table.
Place the face towards you, and the two holes of the back downwards.
Push each side of the face until the end of the spring.
Pull the face towards you until the buttress.
Push the lockings of the runners in opposite sides, while still pulling towards you.
2. Determine the axis of the holes, and pull the supply cable
Position the casing at the desired place, and put screw n°1
Figure 1 : Vis n°1
Level up
Figure 2 : Casing levelling

Trace the two circles, using the holes as pattern
Figure 3 : Air circulation holes
Determine the center, using the supplied cardboard circle
Trace the supply cable output
Figure 4 : Alimentation output

v1.2 4
Take off the screw and the casing.
Figure 5 : Casing taking off
3. Make the holes
4. Supply cable
Place the supply cable at the level of the intended output.
Let the cable have 50cm extra length.

5. Place the empty casing on the wall
Place the casing facing the holes.
Make the supply cable enter the casing via the intended hole.
Put the first screw.
Level up.
Put the remaining screws.

6. Place the ducts
Put a foam or silicon joint on the support in a temperate room in order to insure the joint
adherate on the support.
Figure 8 : Compression joint Figure 9 : Compression joint

v1.2 6
Put a compression joint on each tube support
Figure 10 : silicon joint
Put each support in a 90mm duct.
Figure 11 : Fixation of the support on the duct
Place a 90mm duct in each orifice. Pay attention so the ducts exceed the exterior side by 5
mm.
Figure 12 : Installation of the duct

v1.2 7
The fouled air duct (on the right while being inside) has to be inclined towards the outside (at
least 1,5% slope).
Figure 13 : Duct inclination Figure 14 : Duct fixation
Use foam or silicon to make sure everything between the hole and the ducts is airtight
Take off the front face of the AHU by unscrewing the 4 screws.
Figure 15 : Font face taking off

v1.2 8
Turn the AHU and place a 80 mm diameter duct and about 30 cm long on the viciated air
exit.
The length (about 30cm) must always be shorter than the wall thickness
La longueur (30 cm environ) devant toujours être plus faible que l’épaisseur du mur
Make sure the ducts/casings are airtight, use a silicon joint on the duct and push the duct
inside the cuff.

7. Place the AHU
Connect the floating cable from the AHU to the current supply.

v1.2 9
Slide the AHU into the casing and push until the end of the spring.
Figure 18 : Fixation AHU / Casing Figure 19 : Fixation AHU / Casing
Push again on each side of the face to unlock the AHU.

v1.2 10
Turn on the AHU.
Measure the in situ flows.
Close the AHU
