Page 13: Safety Instructions
Use the device for the appropriate purpose only. Appropriate use EMD series electronic condensate drains are intended exclusively for the following purpose: Draining condensate from compressed air system (air compressors, air receivers/pressure vessels, air dryers and air filters). - Page 14 Do not use tapered thread! Internal thread The EMD series could be mounted horizontally (left) or vertically (right). But, it must not be rolled aside more than ±15°. The horizontal position is preferred in case of a lot of debris in condensed water.
- Page 15 EMD Installation and operating manual Horizontal drainage pipes must be inclined so that air could escape from EMD and that debris is flushed toward EMD (left). When horizontal drainge pipes are long, venting should be built (right). If if the bottom connection is used, the height of Use upper connection to mount venting line back the upper connection must be lower than the to pressure equipment (e.g.
