5 Maintenance/Error Messages
To keep the equipment in good working order you should follow the guidelines below.
•
Examine the equipment regularly for mechanical damage
•
Do not use solvents or liquid cleaners on the control panel
5.1
Cleaning
•
Clean the unit as needed
•
Vacuum with HEPA filter dust and dirt from the furnace rather than blowing. This will minimize the amount of air
born dust particles
•
Clean exterior surfaces with a soft, damp cloth using a mild detergent and water after unit has cooled
•
DO NOT IMMERSE IN WATER!
5.2
Temperature Calibration
Every Vulcan furnace is calibrated in the factory at 1000°C. Under normal use the furnace should not require
calibration. The electronics used in the Vulcan furnaces are very stable and will have minimal drifts over the life of the
furnace. Thermocouple replacement could be a potential requirement for calibration if high accuracy is required.
For example:
A furnace is operating at a stable temperature and a separate thermocouple is inserted in the furnace and a digital
thermometer measures the muffle temperature. The display shows 875°C which is the programmed temperature but
the digital thermometer reads 868°C (need +7°C offset adjustment).
Make sure the power switch is in the off position. Press and hold the knob in while turning on the power switch. Hold
the knob in for approximately 10 seconds until the offset screen is displayed. Release the knob. Turn the knob to the
desired offset. Press the knob to store the offset and return to the main display.
WARNING
This equipment contains dangerous voltages. Service and repair work should be carried out by R&R qualified
