Running Indicator
4. Operating Instructions
a. Place the sample in the oven and lock the door by rotating the handle downwards.
b. Close the Vacuum Valve and Inert Gas Purge Valve by rotating the dials clockwise.
a. Check the Vacuum Release Valve, and rotate closed if necessary.
c. Turn on your pump and open the Vacuum Valve by twisting counterclockwise.
d. When your desired vacuum level has been reached, close the Vacuum Valve, then, power off
your vacuum pump.
e. Turn on the oven and set your desired temperature. The oven may take 30 –60 mins to reach
initial temperature, depending on settings.
f. We recommend letting your oven sit for 10 –20 minutes upon reaching temperature to allow
for optimal heat distribution. For detailed controller instructions, please see the next section.
g. To release vacuum upon completion, first power off the oven.
a. Rotate the Vacuum Release Valve to release your vacuum using atmospheric pressure. Or,
b. Connect an inert gas source to the Inert Gas Purge Port, and open the Inert Gas Purge
Valve to release your vacuum using an inert gas such as nitrogen.
h. When ambient pressure has been restored inside the oven, the door will open. You must wait
until pressure is completely restored, or a vacuum seal will hold the door closed.
a. Sometimes, it may be necessary to use your thumb or a flat screwdriver to separate a small
section of the Door Gasket from the glass window. A small “flick” will be enough to break
the seal- do not pierce the gasket! Please contact our support if you require assistance.
i. Take proper precaution when removing items from the oven as the contents will be hot!

5. Temperature Controller Detailed Operation
5.1. Time Settings
1．When the instrument is switched on, pressing one time the button, the last value of the set time
(timer) starts flashing. Set the desired value (hh:mm) by pressing or keys. It’s possible a quick
movement between the digits using the button.
2．Confirm the set value with another press of button.
NOTE: the value “00:00” indicates the operating mode "continuous", that means once you start the
operating cycle by the START / STOP button, it continues maintaining the set temperature until it is stopped
manually (START/STOP)
3．If you set a value of time, such as 1 hour, the instrument will reach the set temperature and maintain it
for an hour.
5.2. Temperature Setting
1．When the instrument is switched on, pressing one time the button, the set temperature value starts
to blink. Set the desired temperature value (in Celsius degrees) pressing keys.
2．It’s possible a quick movement between the digits using the button.
3．Confirm the set value with another press of button
5.3. Start / Stop Operation
1．After setting the operating parameters, pressing button with long pressure (4-5 seconds), the
heating cycle starts for the defined time in hh:mm or continuous (00:00). The word “end” at the top right
corner of display disappears, the message RUN appears in the bottom left corner and display shows
contemporary: timer, temperature measured inside the chamber, set temperature a if present
2．At any time, you can always manually stop the cycle by pressing the button with long pressure (4-
5 seconds).
3．Once the set time or after manual stop, the instrument beeps intermittently, the icon of visual alarm
and the word "end" appear on the display. Pressing any button, it’s possible to silence the audible signal
and the icon appears.

52411Vacuumoven0.9_1.9_ver_1.0 as version
www.coleparmer.com
NOTE: the acoustic signal will not end until it is stopped by the operator, but the heating cycle is
terminated so for the samples inside the instrument will remain exposed to the internal temperature
the chamber.
5.4 Delay of Heating Cycle Start
It’s possible to set a delay (hour and minutes) of heating cycle start.
1. Simultaneously Press and for few seconds until the time position shows “LK 0000”
confirm the“0000” password pressing shortly one time .
On the top right part of display the parameter “dy” (delay) appears close to value 00:00.
2. Set the desired delay value (hh:mm) pressing or keys. It’s possible a quick movement
between the digits using the button. Confirm the set value with another press of button.
The display comes back to the standby screen.
3. Pressing the button with long pressure (4-5 seconds) the instrument starts the work cycle but it
doesn’t immediately heat: the word “end” and the set delay time alternately blink on the top right part
of display, counting the wait time until the real starting of heating.
Once the delayed time is passed the instrument starts to heat and the regular timer appears on
display.
5.5. Alarm / Faults
The oven has a built-in overtemperature protection circuit. If the oven’s temperature overshoots, the
controller will enter an Alarm Mode that disables all heating elements to protect your samples.
When in Alarm Mode, a red alarm indicator will display on the screen. The oven will automatically
resume operation when the temperature has dropped back below the overshoot threshold.
Setting the temperature setpoint higher will also resume heating function.
If your oven alarm is sounding due to an elapsed timer, press the Any key to mute!

6.1. Calibration
While the oven arrives pre-calibrated from the factory, certain adjustments may be necessary for optimal
performance. Please note these adjustments will affect your oven settings! We recommend writing down
any factory settings prior to adjustment so they may be reset in the event of undesirable operation.
Probe Calibration
Follow the instructions below to adjust the temperature readout. These steps are only necessary in the
event there is a discrepancy between the display and measurements taken with an alternate device.
For example: a thermometer placed inside the oven with a different measurement than the controller.
Please note: laser probe measurements will be inaccurate without compensating for emissivity. Refer to
your laser probe’s user manual.
1. Simultaneously Press and for few seconds until the time position shows “LK 0000”
2. Press to set LK 0003
