Max Fig 1 When heat recovery from the extract air is insufficient to obtain set supply air temperature an electrical heater battery will automatically be switched on In general it is recommended to set supply air temperature as low as possible avoiding the feeling of draught This gives the ultimate energy and ventilation efficiency Summer operation When supply air temperature exceeds set temperature the rotor will stop and there will be no heat recovery summer operation VR 300 ECV B Operation and maintenance instructions 206788 16 11 2010 3 Systemair AB Extract from cooker The VR 300 ECV B is designed to be connected to a special cooker hood adapted for its use systemair 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 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 t
