SUPPLEMENT TO THE ELECTRONIC STEAM

POWER HUMIDIFIERS MODEL #S2000 AND S2020

Field Controls Humidifiers

This service bulletin describes the steps that may be necessary to replace your existing Model ESU14 or ESU20 Steam Humidifier, with the new Model S2000 or S2020 Power Steam Humidifier. The new “S” models have been redesigned and improved. There are some differences which must be taken into account when installing this unit or replacing an older model.

1. MOUNTING - First and most important is the mounting of the new humidifier. The new model has a larger reservoir but measures the same width and height as the old “ESU”. The reservoir protrudes deeper into the duct and occupies more space inside the duct. The new “Under Duct Mounting Flange” is an integral part of the reservoir. As a result, the modification to perform when mounting the new S2000 or S2020, is to snip and lengthen the flange dimension on your existing reservoir cutout opening in the warm air supply plenum.

With this modification done, you should be able to insert the new humidifier into the cutout opening and secure the unit with the 8 self tapping screws provided. The hole dimensions on the front plate have not changed and should match up. If necessary, locally reinforce the opening with sheet metal sleeves to insure that the unit will remain level and not sag with the added weight of the water.

A 2nd template is included with the “S” series humidifiers for mounting the unit under the duct on the return or cold air side of the furnace. Note that there is no need to order an under the duct mounting kit, due to the new integrated mounting flange.

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.
