Install the drain remembering that the condensed water drains into the pipe by gravity, therefore, install it with a small slope, to facilitate the flow. Install the drain outlet in a siphon box, preventing the return of bad smell to the equipment. Use PVC pipes and never form curves that hinder the flow of water.
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.
