3.DRAINS - It is still necessary to run an overflow drain line from the humidifier to a suitable drain. Now, it is also required to run an additional drain line from the new automatic drain valve to a suitable drain.

The new “S” series humidifiers have an automatic drain valve which will drain the tank every 12 hours, to minimize chemical buildup inside the tank. The water is allowed to cool down to 140 degrees F. before the water is drained out.

The humidifier drains by gravity only, so it must be mounted at a sufficient height to allow for proper drainage. DO NOT route the drain hoses above the level of the humidifier, and watch for kinks or cuts in the hoses.

If you have a basement installation and require draining into a condensate pump, we recommend a Beckett Model # CU451ULHT or CU551ULHT. These pumps are rated for high temperature water and have built in check valves.

4.WATER - The frequency which the water fill solenoid on the new steam unit will activate can exceed the older model. This more frequent filling of the tank may be noticeable in the form of water hammer noise or spikes in the water line. Install an optional water hammer arrester #WH-100, and the noise will dissipate.

ESU14 specifications

The Field Controls ESU14 is an advanced air quality solution designed to enhance indoor environments by providing superior filtration and purification capabilities. Built for both residential and commercial applications, the ESU14 stands out due to its innovative features and technologies that ensure cleaner air and improved comfort.

One of the main features of the ESU14 is its high-efficiency particulate air (HEPA) filtration system. This system captures up to 99.97% of airborne particles, including dust, pollen, allergens, and even some viruses and bacteria, as small as 0.3 microns. The HEPA filter's efficiency not only aids in maintaining better air quality but also contributes to reducing respiratory issues for occupants, making it a vital addition for homes with allergy sufferers or those sensitive to air pollutants.

Additionally, the ESU14 utilizes advanced ultraviolet (UV) light technology. This technology helps to neutralize harmful microorganisms that may be present in the air or within the HVAC system. The UV lights work to disinfect the air, improving overall air quality and ensuring a healthier environment. This makes the ESU14 an ideal choice for spaces that require stringent hygiene standards, such as healthcare facilities or daycares.

Another significant characteristic of the ESU14 is its user-friendly interface. The system is designed for easy operation, allowing users to monitor air quality levels and system performance with minimal hassle. With smart technology integration, the ESU14 is compatible with various home automation systems, allowing for seamless control via smartphone apps or through voice-activated devices.

The ESU14 is also engineered with energy efficiency in mind. By optimizing airflow and reducing energy consumption, it minimizes operational costs while effectively purifying the air. Its durable construction ensures a long lifespan, and routine maintenance is straightforward, making it a practical choice for long-term air quality management.

In summary, the Field Controls ESU14 combines high-efficiency HEPA filtration with cutting-edge UV technology to deliver an effective air purification solution. Its user-friendly features, energy-efficient design, and robust performance make it a top choice for those seeking to improve indoor air quality while promoting a healthier living or working environment.
