K41100 - COMMISSIONING 3.1 - Installation Install the appliance on a horizontal and stable surface. The environment must be clean and free from dust. Avoid locations that would expose the appliance to direct sunlight or draughts. Unpack and remove the protective packaging from the appliance and its accessories. - Page 15 K41100 Position the flue extension. No connection for smoke evacuation should be made on the flue or its extension. The flue must remain free to ensure optimum exhausting. Any connection on the flue or its extension risks causing: - condensates on the appliance pipework - a counter-pressure that would interfere with the test by modifying the flow rates and causing leaks through the hot cover of the oven.

Page 23: Important Remark
K41100 If the regulator is waiting (no test in progress) the safety device switches the regulator to manual mode (the AUTO LED goes out and the MAN LED lights up). When the oven is cold, the regulator reverts to wait mode. In the case of an alarm, it is always necessary to investigate the cause. -

Page 25: Checking The Oven Temperature
K41100 5.2.1.2 Removing carbon deposits from the oven The outlet at the base of the oven may be a point for deposits of carbon, which by accumulation could block the oven exhaust. To avoid total blockage of the oven, it is preferable to clean this part regularly, using the cable supplied. -
Page 26: Main Causes Of Poor Results
K41100 6 - MAIN CAUSES OF POOR RESULTS Since the function of the appliance is to process a sample, the cause of poor results may not be attributable to the appliance. Poor manipulation of samples (with absorption of humidity at the end of the test), inaccurate weighing, an error in entering the weight, an error in identifying the samples may all cause errors in the expression of results. - Page 27 K41100 7- LIST OF ACCESSORIES AND SPARE PARTS Designation Cleaning cable Mixed vial holder Small hole vial holder Large hole vial holder Flue extension Handling hook Complete oven Oven thermo-couple Safety thermo-couple Insulating cover Glass vial, 2 ml Glass vial, 16 ml...
