5.0 Precautions
This unit has been designed with a dampered vent from the chamber. In order to
work effectively and safely, some precautions will need to be taken by the operator.
• In most applications, the exhaust damper will need to be open during drying or
degassing for best results.
• This oven is not an explosion proof oven and is not designed to handle com-
bustible gasses. Do not place explosive, combustible or flammable materials into
the chamber.
• Some of the out-gassed byproducts may be hazardous or unpleasant to operating
personnel. If this is the case, the exhausts should be positively ventilated to the
outside and dealt with according to local regulations. Your dealer can provide
you with a power exhaust that greatly helps under these applications.
• Do not place sealed or filled containers in the oven chamber.
• This oven is NOT designed for use in Class I, II, or III locations as defined by the
National Electrical Code.
• This oven is not intended, nor can it be used, as a patient connected device.

6.0 Operation
Power Supply
The power supply must be properly grounded (earthed) and correctly sized to
match the unit data plate rating. The supply voltage must match the data plate
voltage within 10%. If supplied with a detachable cord set, plug the female end
into the inlet on the unit and the male plug into the supply. Assure that units
requiring a fuse have a fuse installed.
Push the power switch to the ON position and turn the Over Temperature
Thermostat to its maximum position, clockwise so it will not interrupt the setting of
the Main Temperature control.
6.1
Setting Main Temperature
Place the reference thermometer through the exhaust port on top of the unit; a clip is
provided with your accessory package. See Figure 3.
The operating range for this oven is ambient room temperature + 5°C to 200°C. To
set the Main Temperature Controller turn the knob to the desired oven temperature,
using the graduated dial as a reference guide. Allow one hour for the temperature
to stabilize. Using the reference thermometer, verify the oven temperature; if it is
not at the desired value, turn the control knob up or down as needed. Allow the
temperature to re-stabilize, continuing the process until the exact desired tempera-
ture is achieved.
Note: Slight vapor or smoke may occur in the initial heat-up. This is a normal occur-
rence when the oven is first brought up to temperature and protective coatings on
the element become hot.
