Install the drain remembering that the condensed water drains in the pipe by gravity, therefore, install it with a small slope, to facilitate the flow; Use PVC pipes and never form curves that hinder the flow of water. Install the drain outlet in a siphon box, preventing the return of bad smell to the equipment.
After installation, perform the drain test as follows: Add water to the tray with the aid of a container until the correct flow of water is observed at the drain outlet point.
