How do I get at the unit on our cooktop. Are there screws on the bottom side? Do you have a schematic on the installation?
Answer Hello Roger,
Discontinue the power supply to the unit. remove the tape and possible screws connecting the ducting in the cabinet. If the unit has braces under the countertop, these will have to be loosened ort removed. Lift the unit from under the counter and set it diagonally on the countertop over the opening, (towels can be placed under the corners to prevent damage to the countertop). You will now remove the screws around the perimeter and the screws around the inside of the top frame. The top should come off to gain access to the inside components.
