8 Maintenance
The calibration instrument has been designed with the utmost care. Ease of op-
eration and simplicity of maintenance have been a central theme in the product
development. Therefore, with proper care the instrument should require very
little maintenance. Avoid operating the instrument in an oily, wet, dirty, or
dusty environment.
• If the outside of the instrument becomes soiled, it may be wiped clean
with a damp cloth and mild detergent. Do not use harsh chemicals on the
surface which may damage the paint.
• Be sure that the well of the furnace is kept clean and clear of any foreign
matter. Do not use fluids to clean out the well.
• If a hazardous material is spilt on or inside the equipment, the user is re-
sponsible for taking the appropriate decontamination steps as outlined by
the national safety council with respect to the material.
• If the mains supply cord becomes damaged, replace it with a cord with
the appropriate gauge wire for the current of the instrument. If there are
any questions, call Hart Scientific Customer Service for more informa-
tion.
• Before using any cleaning or decontamination method except those rec-
ommended by Hart, users should check with Hart Scientific Customer
Service to be sure that the proposed method will not damage the equip-
ment.
• If the instrument is used in a manner not in accordance with the equip-
ment design, the operation of the furnace may be impaired or safety haz-
ards may arise.
• The over-temperature cut-out should be checked every 6 months to ensure
that it is working properly. Set the unit to 300°C and let it stabilize. Turn
the adjustable cutout knob down until the cutout is activated. Turn the
knob back up and push the reset button.
• Periodically remove the equilibration block and use emery cloth to re-
move the oxidation build up on the block.
