Thank you for the question. I would suggest reviewing the installation instructions for Samsung over the range microwaves which can be downloaded through this link: 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.
There is no specific warning against tieing the vent duct into a common system from the perspective of Samsung's installation instructions. However, it is important to make sure that the installation does conform to Samsung's recommendations for outside exhaust venting. In addition, I would suggest contacting your condominium association with regard to their requirements and recommendations for tieing into their system to ensure the installation conforms to your local building codes.
