No, a type E or F kitchen hood cannot be connected to an older ULV or USV unit. With such a connection, the switch may fail, and you will not be able to regulate the motor speed. To ensure correct operation and avoid damage to the equipment, the kitchen hood and the unit must be compatible and designed for use together.
