Resolution:
Generally, the modification that you are interested in must be available from the factory as part of your equipment's model number. You can look in a current catalog or IOM to see the model number selection possibilities. Once you have determined that your modification is normally selectable as part of a model number then you can contact the Field Modification team through: https://tranepresalesupportcso.zendesk.com/hc/en-us/requests/new
If you're looking to add an option that is not standard, contact Trane Creative Solutions for next steps.
