Operation
Before operating the oven, always observe the following Safety Precautions:
This unit is not explosion-proof, do not use in the presence of flammable
or combustible materials; fire or explosion may result. Unit contains
components, which may ignite such materials.
Fumes and spillage from acidic solutions cause corrosion of the stainless
chamber. Care should be taken to maintain a neutral pH at all times.
• Wear insulated gloves
• Use tongs
• Never stand in front of an open oven
• Use safety goggles
Caution Removal of safety shield, shelf support, and/or shelf will result in
voiding of warranty. Heater cover is not a suitable replacement for a shelf
and must not be used as such. Use of heater cover as a shelf may result in
fire.

The 3051 Series controllers feature a deviation alarm which alerts the
operator and interrupts heater power whenever the actual oven temperature
differs from the set temperature by more than 5°C. This set limit cannot be
adjusted by the operator.
If the actual temperature exceeds the alarm limit, the alarm indicator LED
will light.
The reference point for the alarm is the set temperature. Any change in the
set temperature will cause a corresponding shift in the alarm temperature.
Example:
If the set temperature is 150°C, the alarm will trip at 155°C. If the set
temperature is changed to 200°C, the alarm will follow the set temperature
and trip at 205°C.
Changing the set temperature to a value more than 5°C below the present
oven temperature will trip the alarm. Power is removed from the heater
when an alarm condition occurs.
