Wiring The Hood With An Inline Blower - Thermador PROFESSIONAL SERIE Operating And Installation Manual

Wiring the Hood with an Inline Blower

To minimize noise in the kitchen, these blowers are

an attic, for example), this may be an appealing option.
For complete installation instructions see the instructions
supplied with the blower unit.
