Position the unit in its ultimate operating location. Keep a minimum of 4"
of airspace around the unit and a minimum of 18" above the unit. The
portholes 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 the 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.

The unit is ready for your immediate use. All control parameters, calibration
and, tuning has been done at the factory, no adjustments are necessary.
Turn the power switch to the ON (UP) position. All LED's on the temperature
controller will light up and display the current chamber temperature. The OUT
and RUN indicators will also light up once the unit has been powered ON.
Read Operating InstructionsThoroughly Prior to Operation
Safety Precautions
Once the unit nears the desired temperature, allow the oven to cycle
for 20 minutes at the set-point before the temperature becomes fully
stable. Upon each initial powering-up, the control may typically overshoot
the set-point by 3 or 4 degrees especially if the temperature set is close to
the operating ambient temperature. After equilibrium is achieved the
control will hold the set temperature within 1 unit degree F.

Read Operating Instructions thoroughly prior to operation and observe the following safety precautions:
Use only a grounded outlet that is rated for your model's electrical requirement.
Do not modify the oven or factory control settings to operate the oven above the stated maximum operating
temperature.
Exterior surfaces on the GCE and GCE-LT Lab Oven models may become hot to the touch when operating at higher
set temperatures.
Do not leave the oven unattended during operation.
Do not place volatile or combustible materials inside the Lab Oven.
Do not use any flammable solvents or gases or materials that may contain flammable solvents or gases, or with
liquids, vapors or chemicals that produce toxic gases.
Do not use open liquids in the oven.
Conduct periodic maintenance as required.

TEMPERATURE OFFSET / CALIBRATION
Your unit has been calibrated at our factory using a
NIST-certified temperature instrument.
Over time a temperature adjustment (offset) may be neces-
sary to maintain the unit’s controller temperature reading
consistent with the interior temperature. To maintain this
temperature accuracy, we recommend verifying twice a year
that there is a temperature consistency between the control-
ler and the chamber using a known accurate temperature
measuring device.
Place a trusted, preferably certified digital temperature
probe at the center of the unit’s chamber.
Record the temperature reading at the controller and at
the center of your unit’s chamber.
Access the OFFS parameter and input the tempera-
ture difference from your controller to your digital probe.

CONTROLLER ALARM
Controller Alarm- If the unit exceeds the high limit alarm value, the controller will
stop the heating process and display the ALM indicator on the controller until the unit is
manually reset.
To reset alarm condition- Power the unit OFF and allow it to cool down to room
temperature before powering ON. If the problem persist contact technical support.

Chamber Loading
The oven’s chamber temperature stability can be affected by changes in ambient (room) temperature and/or equipment
running in close proximity (creating microclimates) or cycling on the same electrical circuit. Take time to see how unit
location or changes in room temperature from seasonal heating or air conditioning may influence the oven’s set
temperature. For best chamber temperature stability, keep the ambient temperature stable.
Important Opera�onal Notes
FIG. 6 FIG. 8 FIG. 7
Understanding the unit's thermal convection and "load-effect" are necessary to optimize oven’s performance. Article or
media processing times and/or uniformity are largely dependent on load density and positioning.
Process the smallest possible load the application or workload will permit. For best processing of small multiples or a
single item, adjust one shelf so that the article(s) is centered in the Lab Oven.
Avoid placing articles or media against or within an inch of the walls especially on the lower shelf. Heated air from the
lower heat-shield, is designed to travel up the sidewalls and can have a slightly elevated temperature from the setpoint
and the rest of the chamber.
Avoid using large solid trays or foil on lower shelves, this can drastically limit heat to shelves and articles placed above.
Important guidelines to chamber loading and processing:
Load the oven so that heated air circulation within the chamber is not impaired.
Avoid extremely large (in quantity or size), or high-density loads ( FIG. 7 ). This will show by non-uniform processing and
long or impossible "heat-through" times. To help determine a large load's suitability, use the set-point recovery time (the
time it takes for the temperature to recover to the original set temperature once load is placed), as a guide.
Leave a space between articles on the shelf.
It is important to note that large trays placed on lower shelves prevent enough heat to rise within the chamber. (FIG. 8 )
To reduce recovery time, reduce load proportionally. Also, large loads may require an elevated set temperature for the
solution to reach and maintain a lower target temperature. When possible, measure large loads or solution
temperatures directly with an ancillary thermometer or probe. Probes can be inserted at the top port.
Stagger articles from those on lower shelves in a "V" formation. (FIG. 6 )
SPACE LEFT INTENTIONALLY BLANK

Oven Safety Reset- To protect the oven’s electrical components and for the
safety of the user, if the unit exceeds its maximum temperature, an internal safety
“snap disc” will cut power OFF to the unit until it is manually reset.
To Reset - unplug the oven, lay it on its back, and remove the bottom cover.
Locate the round safety “snap disc” and push on the button to reset.
Maintenance / Cleaning Procedures / Common Replacement Parts
The Lab Series Ovens are designed to be virtually maintenance free. But operational safety requires periodic cleaning
and chamber temperature accuracy verification (see Temperature offset/calibration on page 3 of this manual).
Cleaning Procedure - 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. To reduce the risk of fire, it may be necessary to remove the
bottom plate cover to clean or vacuum any dirt and dust build-up. To clean the exterior and interior surfaces, use a
damp cloth or an all-purpose cleaner. Avoid commercially available oven cleaners.

Troubleshooting
1. Check if the unit tripped a GFCI outlet or fuse. Try a non GFCI
power outlet connection before moving to number 2 on this list.
2. Check the (red) plastic fuse holder in the back of the unit for
missing or broken fuse. Replace as needed.
3. Check all wire connections in the electrical area (bottom) and
make sure there are no loose or disconnected wires in the unit.
Oven not heating
or over heating.
2.Turn unit OFF to clear (ALM) Alarm and allow it to cool down
to room temperature before restarting . If the problem persists
contact Quincy Lab. for further assistance.
1. Tripped GFCI power outlet
2. Damaged or missing fuse
3. Disconnected / loose wires.
2. The unit overheated and alarmed
PROBLEM POSSIBLE CAUSE WHAT TO DO BEFORE CALLING TECH. SUPPORT
1. Make sure the setpoint temperature is set correctly on the
SP parameter (see pg. 3) and is above the stated minimum
required temperature range.
1. No Heat: Set temperature not set
correctly or set too low.
3. Incorrect OFFSET (OFFS)value 3.Verify that the Temperature Offset is between -10°F to10°F.
Any value higher than this may affect the heating process. Bring
value down to zero, and perform a temperature calibration (see
pg. 3 for more information).
