MAINTENANCE AND CLEANING GUIDE

SERVICE AND REPLACEMENT GUIDE

Your PMA-5/12 or PMA-5/18 has been designed to be serviced quickly and easily. In fact, any individual who has average mechanical ability can do the work. Our Service Department is also available to you Monday through Friday from 7:00 a.m. to 5:00 p.m. (Central Standard Time) should you find yourself with a situation or problem other than what is outlined here. Our technicians are also available via pager from 7:00 a.m. to 10:00 p.m. during week-ends and holidays. Call NU-VU®at (906) 863-4401 and ask for our Service Department to order replacement parts, ask questions, or offer comments.

This SERVICE AND REPLACEMENT GUIDE has been prepared to cover most normal service problems. If this "trouble-shooting" information does not provide a solution for your particular problem we ask that you call us for direct assistance. Calling our Service Department before calling in a repair technician can usually save you both time and unnecessary expense. We want to do everything we can to minimize your "down-time".

You may need to remove an access panel for servicing. DO NOT allow any access panels to drop. When work on the component is finished replace the panel with care, making sure that all wires are properly placed and not pulled or pinched. If more than one component is being worked on try to remove only one component at a time.

TEMPERATURE CONTROL, How to Adjust:

A.Place a reliable thermometer (or the thermocouple of a test instrument) on a pan in the center of the Oven. Turn the unit ON and set the Temperature Control [22] to its normal setting. Allow the equipment to reach a stable operating temperature.

B.Compare the Temperature Control setting to the reading on the test instrument when the Temperature Control Indicator Light [23] goes out. If there is a difference of 25° or more you will most likely need to recalibrate the Temperature Control.

ATTENTION: Please call the NU-VU®Service Department for the correct procedures to recalibrate your Oven!!!

C.If the difference is more than 5° but less than 25° a simple dial adjustment may solve the problem:

1.Remove the Knob of the Temperature Control by pulling it straight out from the face of the Control Panel.

2.Hold the black Knob securely with the back of the clear plastic dial toward you. Use a Phillips screwdriver to loosen the two screws from 3/4 to 1 full turn, but do not remove them!

3.To increase the temperature inside the Oven carefully rotate the index line on the clear dial clockwise. Each "click" of adjustment is equal to approximately 5° of temperature change in the Oven. To decrease the inside temperature rotate the clear dial counter-clockwise.

4.Gently tighten the dial screws and install the Knob. Check the Control setting against the test instrument and repeat this procedure if necessary.

D.If this procedure fails to bring the temperature reading within the desired specs the Temperature Control or Temperature Control Sensor [6] may need to be replaced.

PMA -5/12, PMA 5/18 specifications

Nu-Vu PMA 5/18 and PMA 5/12 are advanced models of portable modular air handling systems designed to offer superior climate control solutions for diverse environments. These units are particularly well-suited for various applications, such as industrial, commercial, and institutional settings, where air quality and energy efficiency are paramount.

One of the key features of the Nu-Vu PMA series is their compact design combined with powerful performance. The PMA 5/18 and PMA 5/12 models are engineered to efficiently manage larger volumes of air while maintaining an excellent balance between space-saving convenience and robust functionality. Their modular design allows for easy integration into existing systems or new installations, making them highly adaptable to different setups.

In terms of technology, both models utilize cutting-edge heat recovery systems that enhance energy efficiency and reduce operational costs. By recovering waste heat from exhaust air, these units can precondition incoming fresh air, leading to significant energy savings and improved HVAC performance. This feature also contributes to maintaining optimal indoor air quality by effectively regulating temperature and humidity levels.

Another notable characteristic of the PMA series is their advanced filtration systems. Equipped with high-efficiency particulate air (HEPA) filters, they ensure that even the tiniest airborne particles are captured, making them ideal for environments that require strict air quality standards. This is critical in applications ranging from laboratories to healthcare facilities, where airborne contaminants can pose serious health risks.

Ease of maintenance is also a consideration in the design of the Nu-Vu PMA 5/18 and PMA 5/12 models. Their user-friendly layout allows for quick access to key components, reducing downtime during servicing. This ensures that the units can operate seamlessly for extended periods, making them reliable assets in maintaining a controlled environment.

The PMA models are also equipped with sophisticated control systems that allow for precise monitoring and adjustments of air flow and environmental conditions. This level of control not only enhances comfort but also facilitates compliance with industry regulations and standards.

In summary, the Nu-Vu PMA 5/18 and PMA 5/12 air handling systems represent the pinnacle of portable climate control technology. With their energy-efficient design, advanced filtration systems, and user-friendly features, they stand out as versatile solutions for various air quality and climate management challenges in today's diverse settings.
