Extract from cooker

The VR 300 ECV/B is designed to be connected to a special cooker hood, adapted for its use.
Note! The cooker hood must be equipped with a damper leaving no opening in closed position
(without opening for basic ventilation).
During forced ventilation from the cooker (when cooking) the damper in the cooker hood is opened from
switch "A". At the same time the fans will automatically change to MAX fan speed (3) from switch "B" (Fig.2).

Extract from the cooker is led directly through the extract fan, and not through the heat exchanger. The
capacity of the extract fan is then primarily used for extract from the cooker, but a minor airflow is maintained
through the extract louvers. The opening time for the cooker hood damper can be set from 5 to 60 minutes.
The damper closes automatically according to chosen time, or manually by turning switch "A" to
The system should operate continuously, and only be stopped for maintenance/service.

Maintenance

Maintenance of the VR-300 TK/B should normally be performed 3 - 4 times a year. Apart from general
cleaning the following should be observed:
1. Changing fresh air/extract filter (1-2 times per year or as necessary)
The bag filters cannot be cleaned and must be changed as necessary.
Take hold of the filter frame and pull straight out (Fig.3).
Each time a filter change is performed it is recommended to check the driving belt for the heat
exchanger rotor. Check that the belt is undamaged and tight. Test that the drive belt wheel moves
when the rotor is moved by hand. If the belt needs to be replaced contact your installer.
