8 | Installation Fig. 6 VTR 100/B LITE in a kitchen environment A B C, Electrical stove C, Gas stove D E F G Minimum distance between cabinets (mm) VTR 100/B LITE unit width (mm) Minimum distance between stove surface and cooker hood (mm) Minimum distance between stove surface and cooker hood (mm) When flexible duct is used, distance between the unit and cooker hood is decided by the installer (minimum 100 mm).
Installation | 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 drainage 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.
10 | Installation 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.
Installation | Follow instructions delivered with the cooker hood how to prepare it before installation. 1. Connect the cooker hood to the unit via a flexible duct. Use mounting mechanism which is delivered together with the cooker hood (figure 9, pos. X). 4.2.3 Unit mounting and cooker hood wiring 1. Pull the cooker hood power supply and control cables to the top since the mounted VTR 100/B LITE unit will block access to the back. Fig.

Installation | • Solutions how to hang this panel are described further in this document, see 4.4 Installation of a kitchen furniture panel, page 18. Make sure to find a correct depth for installation of the VTR 100/B LITE unit before proceeding with the mounting bracket installation on the wall. The VTR 100/B LITE is supplied with approximately 1 m of power cable and fitted with a plug for 230 V~, single phase earthed connection located at the top of the unit.
14 | Installation Fig. 13 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 13, 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.
Installation | 4.3.2.1 Installation between or in a cupboard without a base with a cooker hood attached directly to the unit Fig. 14 Attaching the cooker hood directly to the unit 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 protruding screw to prevent over-tightening (figure 14, pos. 3). 2.
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).
Installation | Fig. 18 Placing the unit on the mounting bracket 2. Once all cooker hood cables at the back are led to the top, lift the unit and hang it on the mounting bracket. Warning Beware of sharp edges during mounting and maintenance. Use protective gloves. Consider the unit weight when mounting! Note: Make sure that the unit is completely vertical and horizontal once mounted on the wall. Check with a spirit level.
18 | Installation 4.4 Installation of a kitchen furniture panel The kitchen furniture panel can be mounted directly on the unit, sides of cabinets or installed as a door. Parts for panel installation directly on the unit and sides are delivered with the unit. 4.4.1 Mounting the kitchen furniture panel directly on the unit Depending on the kitchen cupboard depth, the unit might have to be shifted forward for the panel to be aligned with the cupboards.
Installation | Fig. 21 Installation of hooks and mounting of the kitchen furniture panel 2. Sticker with marked holes (figure 21, pos. 1) is included with the unit. Holes mark spots for screws to secure hooks. Place the sticker on a back of the kitchen furniture panel, figure 21, pos. 2), adjust position of the sticker according to the panel size and position of the unit between cabinets. Size of the sticker is the same as the unit. Once correct position is found, attach four hooks (figure 21, pos.
20 | Installation Fig. 22 Installation of bolts and brackets 1. Install four M6 bolts into threaded inserts in brackets and lock bolts with hex nuts (figure 22). Bolts protrusion can be adjusted later. A cross screwdriver and a 10 mm spanner are needed. They are not included in the package. Brackets are adjustable vertically (figure 22, A) and horizontally (figure 22, B). Align the brackets with the underside of the unit. Fully tighten screws after adjusting the brackets. Fig.
Commissioning | 4.4.3 Fitting the kitchen furniture panel as a door Another suggested option is to use hinges instead of brackets and install the kitchen furniture panel as a hinged cupboard door.

Service | Warning • The system should operate continuously, and only be stopped for maintenance/service • Although the mains supply to the unit has been disconnected there is still risk of injury due to rotating parts that have not come to a complete standstill • Beware of sharp edges during maintenance.
44 | Service 9.3.2 Filters It is very important to change filters regularly for performance and energy efficiency of the unit. The factory installed filters are of filter quality G3/Coarse 50% for the supply air and G3/Coarse 50% for the extract air filter. The filters need to be replaced when polluted. New sets of filters can be acquired from your installer or wholesaler. Each filter has a label with an part number for identification. Provide this number when ordering new filters. 9.3.
Service | Reduced airflow 1. Check the display for alarms. 2. Check setting of airflow in the control panel (chapter 5.1.1). 3. Check week program (chapter 5.7). 4. Check if one of the digital inputs 1–3 (DI 1–3) is active and set to off. This would force one or both fans to stop depending on the setup (chapter 8.5). 5. Check if auto mode is active. Auto mode reduces the airflow if actual value from external sensor/sensors is lower than demand control set-point. 6. Check filters.
46 | Service 9.5 Alarm list Alarm Explanation Do the following Fan Indicates error on either supply or extract air fan. The alarm is displayed in the control panel. Check that quick connectors are connected for the both fans. Contact your installation company or place of purchase. EMT/Frost Indicates triggered frost protection (in case of installed water heating battery) or triggered overheat protection (in case of installed electric re-heater battery).
Service | 9.6 Replacing rotor drive belt If the alarm Rotor is raised, see chapter 9.5, the rotor drive belt may be damaged or broken. A spare belt is delivered with the unit.
48 | Service In case both welded belts break it is possible to use joint nipple as a temporarily quick repair solution until the welded belt can be replaced with a new one. Depending of how the unit is installed, it may be not necessary to remove the heat exchanger package in order to temporary repair a broken drive belt if the belt pulley can be accessed.
