Recommended installation location for the outdoor air intake is the northern or eastern side of the building and with a
distance to openings for discharge of stale ventilation air, kitchen ventilator, central vacuum system, waste water drain-
age and other pollution sources like exhaust from traffic etc. Stale discharge air should ideally be led via a roof unit to
the outside and with a good distance to any outdoor air intake, windows etc.
4.2.1 Wall preparation for mounting bracket
The unit should be installed in such a way that there is no
vibration noise coming from the wall on which the unit is
installed.
Important
Make sure to read all instructions before
proceeding with installation procedure.
Installation steps can vary depending on the
type of installation.
1. Prepare the surface where the unit is to be mounted. Make sure that the surface is flat, vertical and that it supports
the weight of the unit. Perform the installation in accordance with local rules and regulations.
Fig. 7 Surface preparation.
C — concrete/bricks, W — wood block, G — gypsum, M — mineral wool
If the wall is from a thick concrete or bricks, no special preparation is needed (figure 7, pos. A), otherwise make nec-
essary adjustments (figure 7, pos. B). The unit weights 48 kg.
Make sure there is a power socket is located nearby the unit, preferably above it. It must be earthed. VTR 100/B LITE
power cable length is 1 m and it comes out from the top left side in right version units and from the right top side in
left version units. Choose power socket location accordingly.

Fig. 8 Installation of mounting bracket without or with wooden blocks
2. Screw the mounting bracket (pos. 1) with the anti-vibration pad (pos. 2) to the wall (figure 8, pos. A). Screws are not
included, choose them based on your wall type. Use appropriate holes to screw the bracket firmly to the wall. Bottom
side of bracket should be 40 mm (H) below top of unit position.
Leave 15 mm gap between the mounting bracket and the cupboard for the cooker hood wires.
Note:
Make sure that the mounting bracket is completely horizontal once mounted on the wall. Check with a spirit
level.
In case the depth of cabinets is much greater than the unit, install wooden blocks (pos. W) to compensate the missing
distance (figure 8, pos. B). Then install the mounting bracket on the upper block. Choose thickness of blocks according
to your needs.
Thickness of wooden blocks should be 25–100 mm. If needed distance is lower than 25 mm, adjust bolts instead of us-
ing wooden blocks (see figure 20).
Caution
Be sure to select the appropriate type and length of the screws so that they could hold additional wood
blocks and the unit itself.

4.3.2 392–10/B cooker hood installation
Product name and number
• 392-10/B Slimline — 77265
The cooker hood must be attached to the sides of cupboards or directly to the VTR 100/B LITE unit first before it can be
mounted on the wall because cooker hood power supply and control cables at the back must be led to the top and al-
ready mounted VTR 100/B LITE unit will block access.
There are two options how to install the cooker hood:
• The cooker hood is attached directly to the bottom of the unit. This option can be used when the whole unit with a
cooker hood will be shifted forward using wood blocks to be alighted with the cupboards or when the cupboard size
matches the unit and no adjustments are needed. This way the unit can be simply mounted directly on the wall with
already attached cooker hood.
• The cooker hood is attached to the sides of cupboards using included brackets. If the unit and cooker hood is not
aligned, a flexible duct must be used since it will be impossible to insert the cooker hood directly into the unit.
Follow instructions in the manual delivered with the cooker hood.

1. Remove the cooker hood filter to access holes at the top of the cooker hood from inside.
Insert included screws (figure 14, pos. 2) into the cooker hood holes, place included plastic spacers on the each pro-
truding screw to prevent over-tightening (figure 14, pos. 3).
2. Place a circular insulation on the cooker hood connector to prevent air leaking (figure 14, pos. 4).
3. Insert the cooker hood duct connector into the unit and tighten the screws.
Screw the cooker hood directly to the bottom of the unit using prepared holes (figure 14, pos. 1).
4.3.2.2 Installation between or in a cupboard without a base using brackets
When the cooker hood cannot be attached directly to the unit, use included brackets. Flexible duct is needed to connect
the cooker hood with the VTR 100/B LITE unit when using this type of installation.
1.
Fig. 15 Installation using brackets
Mark out and fasten screws so that they protrude a few millimetres from both cupboard sides (figure 15, pos. A). If it
is intended to align the underside of the cooker hood with the underside of the row of cupboards, use the upper
measurement 102; see figure 15, pos. A. The cooker hood brackets are adjustable to fit various cupboard depths (fig-
ure 15, pos. B).
2. Move the cooker hood brackets without fully tightening the screws and adjust the brackets so that they fit the sides
of the cupboards (figure 15, pos. C). Hang the cooker hood in the pre-installed screws in the side of the cupboard.
212962 | v02

16 | Installation
Tighten the screws in the bracket and on the wall (figure 15, pos. D). Lock the brackets into position using the locking
screws (figure 15, pos. E).
4.3.2.3 Optional installation in a cupboard with a base
1.
Fig. 16 Dimensions of a hole in the base of the cupboard
Using a saw, cut out a hole in the base of the cupboard. When the VTR 100/B LITE unit is mounted directly on the wall,
the minimum distance from the wall to the hole has to be 55 mm (figure 16, pos. A).
Note:
