Safety Precautions
The AFE 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.
Read Operating Instructions Thoroughly Prior to Operation
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. Important: The exhaust ports should NOT be used as
chamber access for temperature-measuring probes. Insertion of
any such probe or device may damage or unbalance the circulating
fan blade at the top of the oven chamber.
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.

FIG. 1
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. The fan motor will start. All
LED's on the temperature control will light-up for 5 seconds until
the current or actual chamber temperature is displayed.
To view the set temperature press the star key. To change the set
temperature hold the star key together with the up (raise temp) or
down (lower temp) arrow key until the desired temperature is
indicated on the LED display. (FIG. 2) The temperature control is
set at the factory to read in 1/10th degree o F or Fahrenheit units.
To change temperature units or display resolution see: Menu Level
Functions (page 3).
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.

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:
Leave a space between multiple articles on a shelf.
Position articles on shelves as shown in (FIG 4, see insert), for best results avoid placing articles or media
against or within an inch of the walls, especially on the lower shelf, allowing unrestricted air flow around
articles and contributing to even and consistent heating.
Use of large solid trays, or foil on shelves severely limits the oven's ability to distribute heat evenly and
uniformly. (FIG 5, see insert) Since not enough heat rises within the chamber, thermometer readings give
false indication that temperature setting is too low. Higher temperature adjustments made as a result of
these readings could overheat the lower-placed articles or media.

FIG. 4
Do not overload the unit with large (in quantity OR size), or high-density loads. This will show by non-uniform
processing and long or impossible "heat-through" times. To help determine a large load's suitability, compare the
time it takes for the temperature to recover to the original empty chamber set temperature once load is placed.
To reduce recovery time, reduce load accordingly. Also, large loads such as a beaker containing 2 liters of
solution, may require an elevated set temperature for the solution to reach and maintain a lower target
temperature.
Care should also be taken to avoid placing items on the top-most shelf too close to the holes in the fan plenum.
This will restrict the flow of air passing through the plenum and reduce the amount of pre-heated air being
circulated through the entire chamber and cause longer than normal heat-through times and inconsistent or
unstable oven temperatures.
For best processing performance for a single item, adjust one shelf so that the article is centered in the oven
chamber.
NOTE: The unit's minimum operating temperature is largely determined by ambient temperature. The unit can
operate 20 degrees F (approximately 10 degrees C) above room temperature but temperature stability may be
degraded. Temperature stability improves appreciably for settings that exceed ambient by 30 degrees F or better.
As a general rule, the lower the ambient temperature, the lower the maximum adjustable operating temperature.

Menu Level Functions
Access the menu levels for the following functions: (all user applicable functions
FUNCTION SETTING
and their menu locations are high-lighted in white in the Functions Menu Guide below).
~ Change control to read in C or F temperature units.( in level 2)
~ Change to whole degree or 1/10th degree display resolution.( in level 2)
~ Run or Read temperature tracking.( or in level 3)
~ Lock Temperature setting against inadvertent adjustment.( in level 1)
~ Calibrate control temperature to an external standard.( in level 3)
FUNCTION PROMPT
FIG. 3
To access the menu levels:
Press and hold both arrow keys for 3 seconds then release when the "tunE" function prompt is displayed from
within LEVEL 1. When in the function menu the LED display will alternate the function prompt with the current
function setting when keys are released. See "menu entry point" in the Functions Menu Guide below.
To navigate within the menu:
Press the down arrow to move "left" into menu LEVEL SELECTION ( level 1) (FIG 3). Use up and down
arrow keys individually to move "right" or "left" within a level. Hold star key and up or down arrow keys to
move "up" or "down" through levels 1, 2 and 3. (Note: you must be at prompt to move up/down thru
levels)
To change the function setting:
Once at the desired level function prompt, press and hold the star key and press the up or down key to select
or change function setting. Release star key to set the function. Press the up and down keys together to
return to temperature display or control will auto-return in 60 seconds.

Temperature Tracking Feature (example shows readings in degrees C)
This feature monitors the temperature stability of the control during processing. It will record and display: The total
variation or spread between high and low, the absolute or maximum high and the absolute or minimum low.
To start the tracking feature, navigate to the function prompt "ChEK" in menu level 3. While holding the star key
press the up arrow key to select ON. The control will now track the temperature variation until "ChEK" function is
turned off. Recorded readings are retained in memory until "ChEK" is turned on again. Once "ChEK" is turned on
the control will return to the normal temperature display after 60 seconds.
You can view readings at any time during or after tracking feature has been turned off. But de-powering the unit
will reset "ChEK" to OFF and clear stored data. To view readings navigate to "rEAd" prompt in menu level 3. Then:
Release or Press/Hold
Displays variance

TIP: To avoid erroneous tracking data from run-up temperatures or door openings, start the Tracking feature after
articles have been placed and temperature steadies at set point.

Periodic Oven Maintenance
The AFE 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 10 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.
