Explanation of Controls
All Models:
Dial Thermometer - Chamber temperatures are visually displayed by a
direct reading thermometer located on the left-hand side of the control
panel. The thermometer contains a temperature range of -20 to 80°C and
0 to 180°F.
Although the thermometer has been factory calibrated, recalibration after
shipment may be necessary (see Thermometer Calibration ).
INTERIOR "On-Off" Switch - This switch controls electrical power to
the interior duplex outlet located on the upper rear wall of the chamber.
The pilot light located above this switch will be energized after the line
cord supplied is inserted into the electrical outlet and the switch is in the
"On" position.
SAFETY Thermostat - A safety thermostat is provided which will
control the chamber temperature at a slightly higher temperature than
that desired if the control thermostat becomes inoperative. When the
safety pilot light glows, the heater is "Off" and the safety thermostat
contacts are in the "Open" position.
The safety pilot light is "Out" and the heaters are energized when the
safety thermostat contacts are "Closed".
CONTROL Thermostat - A control thermostat is supplied to control and
maintain the desired chamber temperature. The control pilot light glows
when the heater is energized and the control thermostat contacts are
closed.
WATTAGE Selection Switch - This four-position switch is supplied to
allow the operator to select the required wattage to maintain the
desired chamber temperature. The four switch positions are "Off", 350
Watts, 700 Watts, and 1400 Watts.
Usually, the 1400 watt position is used for quick chamber heat-up,
depending on the nature of the load and desired operating temperature.
The switch may later be placed in its appropriate position for normal
operation.
