WATER SUPPLY AND PLUMBING

1.The orifice in the fill valve is sized for an extended water pressure range of 30 to 85 psi.

2.For water pressure between 15 and 30 psi, notify the factory and the next larger size fill valve will be supplied.

3.For cases below 15 psi, notify the factory and a fill valve with an oversized orifice will be supplied.

4.For cases above 85 psi, install a pressure reducing valve in the water feed line to the unit.

5.With extremely dirty or muddy water sources, e.g., some well sources, ensure proper filtration by adding an external filter to the water line entering the unit. (Consult factory for accessories such as filters.)

6.DO NOT use completely demineralized water with this unit as it is the minerals that allow the electrode principle to work.

7.DO NOT use a hot water source as it will cause deposits that will eventually block the fill valve orifice.

1.A copper compression olive type coupling for 1/4" O.D. soft copper tubing is provided with unit and requires no soldering for the water connection to the unit. See Figure #2.

2.An isolating valve should ALWAYS be placed in the feed water line allowing service of the fill valve.

3.Each unit is fitted with a fill solenoid valve located on the base drain pan. Flow orifices are designed

for water pressure from 30 to 85 psi and are protected by the built-in strainer.

4.For inlet water pressure outside this range, the factory should be contacted. (See Water Supply and Plumbing section of this manual.)

START-UP AND OPERATION

Check to see that the unit is securely mounted on a level surface with the proper drain and water supply. Check for correct voltage with appropriately sized service. Check that the steam distributor, steam supply hose, and condensate line are correctly installed and routed back to the unit. Ensure that the external control humidistat is located in an area to properly sense the relative humidity to be maintained by the humidifier, and that the interconnecting low voltage wires between the humidistat and the unit’s control terminal strip are in accordance with the wiring diagram.

Check all electrical connections for wires which may have become loose in shipping. Components damaged due to loose connections are NOT under warranty.

Check electrode plugs to ensure they are pressed firmly onto the electrode pins. Important: Loose connections will cause overheating of the cylinder plugs, possibly melting the plugs and/or cylinder.

Open the isolating valve in the feed water line to the unit.

Make sure the humidistat is set high enough to call for humidification.

Turn on the main disconnect in the primary service feeding the unit and check that unit has power at the primary terminal block.

PUSH THE AUTO ON/OFF/DRAIN SWITCH TO “ON”.

Water will start to enter the cylinder through its bottom port and rise in the cylinder to a point determined by the solid-state control circuitry.

It is not unusual upon initial start-up for the water to fill the cylinder and cycle on the red high water sensor light.

The red light simply acts as a safety to shut off the fill valve and prevent over-filling. With the red light on, the water in the cylinder will continue to heat and, after a few minutes, start to boil. After the boiling action of the water has lowered the water level below the sensor at the top of the cylinder, the red light will go

MES-U specifications

Nortec Industries MES-U is a cutting-edge Manufacturing Execution System (MES) designed to enhance operational efficiency and performance in manufacturing environments. As industry demands for agility and responsiveness grow, the MES-U stands out as a crucial tool for modern manufacturers looking to optimize their production processes.

One of the main features of the MES-U is its real-time data acquisition capability. The system integrates seamlessly with various machines and equipment, collecting data continuously as products move through the production line. This provides operators with an immediate overview of performance metrics, allowing for quick decision-making and timely interventions when issues arise. The ability to monitor production in real-time ensures that manufacturers can maintain high productivity levels and reduce downtime.

Another significant feature of the Nortec Industries MES-U is its user-friendly interface. The intuitive design allows operators at all levels of expertise to navigate the system easily. Key information such as production schedules, machine statuses, and quality control metrics are presented clearly, enabling efficient workflow management. This accessibility is crucial in enabling teams to adapt quickly to changes in production demand and operational challenges.

The MES-U employs advanced analytics and reporting tools that empower manufacturers to leverage the data collected. Users can generate detailed reports on production metrics, quality data, and operational efficiency, enabling ongoing assessment and strategy refinement. This data-driven approach helps organizations uncover insights that can lead to improved processes, waste reduction, and cost savings.

Integration is another critical characteristic of the MES-U. The system can connect with other enterprise-level solutions, such as Enterprise Resource Planning (ERP) systems and Supply Chain Management (SCM) tools, providing a cohesive view of the entire production ecosystem. This interoperability facilitates better coordination between departments and enhances overall organizational agility.

Scalability is also a defining aspect of the MES-U. Whether a manufacturer operates a single facility or multiple sites, the system can adapt to varying levels of complexity and production demands. This flexibility ensures that as companies grow and evolve, their MES can support new requirements without significant disruption.

In summary, Nortec Industries MES-U is a robust and versatile solution that combines real-time data acquisition, user-friendly design, advanced analytics, and seamless integration capabilities. With these features, manufacturers can enhance their operational efficiency, adapt quickly to changes, and drive continuous improvement across their processes.
