2.0 Installation 2.0 Installation Unpacking and Handling When unpacking or moving the product always lift it by its base or by both ends of the main body. Never lift it by its work tube or the surrounding insulation. Use two or more people to carry the product and control box. - Page 7 2.0 Installation Ensure that the product is placed in such a way that it can be quickly switched off or disconnected from the electrical supply. If the product is supplied with a work tube or any accessories fit these into position. For optimum temperature uniformity, insulating plugs should be placed in the tube ends as shown in fig.1.

Page 16: Operation
5.0 Operation 5.0 Operation Operating Cycle This product is fitted with an instrument switch which cuts off power to the control circuit. Connect the product to the electrical supply. Turn on the instrument switch to activate the temperature controllers. The controllers illuminate and go through a short test cycle. -
Page 17: Operator Safety
5.0 Operation Operator Safety The ceramic materials used in this product become electrically conductive at high temperatures. In these models there are partially exposed heating coils in the chamber and there is a danger of contact even with the furnace closed. DO NOT use any conductive tools within the work tube without isolating it. -
Page 18: Tube Life
5.0 Operation Tube Life A ceramic work tube may crack if work pieces are inserted too quickly or at temperatures below 900 °C (when the tube is more brittle). Large work pieces should also be heated slowly to ensure that large temperature differences do not arise. -
Page 19: Running At Low Temperatures
5.0 Operation supply voltage. The models covered by this manual are designed for use over the range of voltages 200 V - 250 V (or, if ordered, 100 V - 125 V), and the power limit parameter is set accordingly. These models may be adjusted to a different voltage within the range: the power limit should be reset to match OP.Hi, see 10.0 Refer to section 3.0 for power adjustment instructions. -
