Some Samsung microwaves are shipped ready for installation as a recirculating vent. If your SMH9187 arrived without the exhaust adaptor installed (see image below), then it should already be set up for recirculating ventilation. If the exhaust adaptor is attached, this is a good indication that you'll need to make some adjustments in order to set it up for recirculating. Please follow the detailed instructions on page 20 of the Installation Guide to remove the exhaust adaptor (which is not necessary for recirculating installation) and to adjust the angle of the blower motor so it faces forward.
Follow this link to download a pdf of the installation instructions if you do not already have a copy: http://ars.samsung.com/customer/usa...
Please note that these instructions are the same for all Samsung over the range microwaves, and are not specific to any one model.
