SERVICE AND REPLACEMENT GUIDE

SERVICE AND REPLACEMENT GUIDE
®
Your NU-VU XO–1 has been designed to be serviced quickly and easily. In fact, any
individual with average mechanical ability can do the work. Call NU-VU
and ask for our Service Department to order replacement parts, ask questions, or offer
comments.
Our Service Department is available to you Monday through Friday from 7:00 a.m. to 5:00
p.m. (CST) should you find yourself with a situation or problem other than we have outlined.
Our technicians are also available via pager from 7:00 a.m. to 10:00 p.m. during week-ends
and holidays.
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 [14] 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 [16] goes out. If there is a difference of
more than 25 you may need to recalibrate the Temperature Control. Please call the
®
NU-VU Service Department at (906) 863-4401 for the proper calibration
procedures before attempting to re-calibrate the Oven!!!
C. If the difference is 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 Access Panel [40].
2. On the back of the Knob you will see two screws. Use a phillips screwdriver to
loosen these screws from ¾ to 1 full turn, but do not remove them!
3. Hold the black Knob securely with the back of the clear plastic dial toward you.
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,
please call the NU-VU Service Department for advanced instructions on calibrating
the control circuit board itself.
