OPERATION INSTRUCTIONS
* Connect the instrument to a ground mains outlet, after ensuring that the Voltage
is the same as given on the name plate. The MANTLE must be connected
to an earthen (grounded) supply.
The Heat controller maintains a set temperature of the heater by turning the power
ON and OFF over short time intervals. The greater the percentage of time the power
is on, the higher the temperature. At the MAX position, power is on continuously and
maximum temperature is obtained. From the OFF position, the knob may be turned
either to the right of left. For fast heatup, turn the knob to Full position. When the
desired temperature is reached, reduce the setting to the point where the
temperature will be maintained. The pilot light is always on when the power is on.
CAUTION : When turning OFF the control be sure the knob is in STOP position and
the indicator light is out.
