- Page 2 EMD12 Installation and operating manual Description EMD12 is an electronically controlled condensed water drain that discharges water trapped in the lowest parts of compressed air installation out of the system. This water is a condensed water vapor that is always present in the atmosphere. Because of laws of physics, some vapor always condenses during compression of air.
- Page 3 EMD12 Installation and operating manual The main mode of operation is a water level triggered discharging. The valve opens when water level in EMD12’s tank reaches threshold and it closes back before the tank is empty. This way, only condensed water is discharged and no compressed air is lost. In the timed venting mode, the valve is opened when water level reaches threshold, too.

- Page 8 EMD12 Installation and operating manual Horizontal drainage pipes must be inclined so that air could escape from EMD12 and that debris is flushed toward EMD12 (left). When horizontal drainge pipes are long, venting should be built (right). Venting is made by T-piece. The T-piece should be located just infront of valve so that path from the EMD12 tank to the venting piece is as short as possible to prevent...
