Page 14: Atmospheres
Atmospheres When an optional gas inlet is fitted, there is a label near the inlet saying "INERT GAS ONLY". In practice, inert or oxidising gases may be used, but not combustible or toxic gases. The chamber is not gas tight, the gas usage may be high and the chamber is always likely to contain some air. -
Page 15: Variable Speed Fan (If Fitted)
Variable Speed Fan (if fitted) If fitted, the variable speed control is fitted in the air circulation fan circuit. A panel mounted rotary dial is used to control the speed. Please note that there is a minimum setting at which the fan motor starts up when the product is switched on. -
