At Smart Family of Cooling Products, we want to provide our customers with the most relevant and up to date information available. With this in mind, we wanted to include easy to access start-up videos for the IDS Sales & Service team.

This particular video demonstrates the start-up of our 30 ton Industrial Air Cooled Air Conditioning Unit with Heat/DH (SACP30A-HS). We appreciate you taking the time to watch and we hope this is a helpful tool for the IDS team.
