Set-up
Position unit in its ultimate operating location. Keep a minimum of
2" of airspace around the unit and a minimum of 10" above the
unit. The port holes at the top of the unit will expel a small amount
of warm air through natural convection. This port can also be used
as an access for an external temperature probe to verify the
chamber's temperature or the chamber's contents directly.
Install adjustable shelf by placing the ends of the wire shelf bracket
into the corresponding holes located on the inner sides of the oven
at the desired height. Push the ends of the
bracket into the holes until the first bends in the bracket are
against the wall, then rotate the bracket down. Place the shelf on
the brackets. (FIG 1)
Plug the unit into a grounded outlet for your unit's rated voltage.
General Operation
The unit is ready for your immediate use. All control parameters,
calibration and tuning has been done at the factory, no adjustments
are necessary.
Push the illuminated power button. All LED's on the temperature
control will light-up and display the current chamber temperature
and the set temperature.
Set temperature is constantly displayed in the lower right-hand
corner of the display. To change the set temperature, simply press
either the up arrow key or the down arrow key, until desired set
temperature is reached. (FIG. 2) The temperature control is set at
the factory to read in 1/10th degree F, or Fahrenheit units.
To change Controller functions see: Menu Level Functions Guide
Read Operating Instructions Thoroughly Prior to Operation
The GCE Series lab ovens are not designed for use with any flammable solvents or gases or for materials
that may contain flammable solvents or gases. Use only a grounded outlet that is rated for your model's
electrical requirement. Oven exterior walls and doors may become hot to the touch when operating at higher
set temperatures. Do not leave the oven unattended during operation, especially when processing materials
that have flash point temperatures lower than the model oven's maximum operating range. Do not modify the
oven or control parameters to operate the oven above the stated maximum operating temperature.

Once the unit nears the desired temperature allow the unit to cycle for 20 minutes at set point before temperature
becomes fully stable. NOTE: Upon each initial powering-up, the control may typically overshoot the set temp by 3 or 4
degrees especially if the temperature set point is close to the operating ambient temperature. After equilibrium is
achieved the control will hold set temperature within 1 unit degree.

Unit Safety Reset- If the unit exceeds its maximum temperature, an internal safety “snap disc” will cut power to the
unit until it is manually reset. To do this, unplug the unit, lay it on its back and remove the bottom cover. Locate the round
safety “snap disc” and push in the button to reset.

(page 3).

Leave a space between articles on a shelf. Stagger articles from those on lower shelves.
Avoid placing articles or media against or within an inch of the walls especially on the lower shelf. Heated
air from the lower plenum openings, designed to travel up the side walls, can have a slightly elevated
temperature from set point and the rest of the chamber.
Use of large solid trays or foil on shelves limits heat to any articles placed on shelves above.
Do not overload the unit with large or high-density loads. This will show by non-uniform processing and/or
long "heat-through" times where control display temp is slow to return or achieve set temperature.
For best processing performance for a single item, adjust one shelf so that the article is centered in the
oven chamber.

Digital Controller Function Buttons
All ovens are Auto-tuned at the factory using the 'At-1' option for faster response time.
You may, however, want to Auto-tune your oven to your specific application. To do this,
once at the 'At' prompt (at left), use arrow keys to initiate either Auto-tune option: 'At-1' (for
40% Auto-tune), or 'At-2' (for 100% Autotune). The 40% Auto-tune (At-1), will stabilize the
oven temperature quicker and with less 'overshoot' than the 100%, but will be somewhat
less precise. The 100% Auto-tune (At-2), will take longer to stabilize oven temperature
but will be more precise, and take a little longer to complete the Auto-tune process.
Chamber Loading
Article processing times and temperature uniformity are largely dependent on load density and positioning. Load the
oven so that air circulation within the oven is not impaired. Here are some general guidelines:

feranheit and

Periodic Oven Maintenance
The GCE Series Lab Ovens are designed to be virtually maintenance free. But operational safety requires
periodic cleaning and chamber temperature accuracy verification. Periodically check the rear air intake vents for
dirt or dust build-up. Keep the intake & exit ports clear of obstruction and clean of dust and dirt. Once a year,
check the actual oven chamber temperature against a known accurate temperature measurement device.
Maintain temperature accuracy to within 5 degrees F of the control setting. Calibrate the control as necessary.
To clean exterior and interior surfaces, use a damp cloth or with an all-purpose cleaner. Avoid commercially
available oven cleaners.

When the oven exceeds its maximum operating temperature by 10°F (5 °C) a safety alarm in the
controller will cut power to the heating elements. Allow the units temperature to drop below its
maximum temperature and/or cool before reset. To reset unit, power OFF and ON to clear alarm status.
If problem remains, please contact technical support for assistance.
