Static environment is defined as operation at atmospheric pressure and
with air - as it is present. In this case, the operator would simply place the
sample in the oven chamber and set the desired temperature.
Controlled environment is defined as operation with the samples in an
inert gas. To accomplish this, perform the following:
1. Place samples in the oven chamber, then close and lock the chamber
door.
2. Close the PURGE CONTROL valve (full clockwise rotation).
3. Open the VACUUM CONTROL valve (full counterclockwise
rotation) then turn on the vacuum pumping system to remove any air
remaining in the oven.
4. Close the VACUUM CONTROL valve and open the PURGE
CONTROL valve slowly to bleed in an inert gas.
5. Close the PURGE CONTROL valve, then set the desired temperature
and process time.
To operate the oven in a vacuum environment, perform the following:
1. Place samples in the oven then close and lock the oven door. Verify
that gasket seal has been coated with high temperature vacuum grease.
Caution Do not use silicone vacuum grease. It will damage the door seal
and has restrictions for some types of materials placed in the oven.

2. Close both the PURGE CONTROL and VACUUM CONTROL
valves.
3. Turn on the vacuum pumping system then open the VACUUM
CONTROL valve (full counterclockwise rotation).
4. The vacuum, in inches-of-mercury, can be read on the
TEMP/VACUUM Display.
