Set-up & Installation
Read Operating Instructions Thoroughly Prior to Operation
Safety Precautions
Read Operating Instructions thoroughly prior to operation. 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 180E models may become hot to the touch when
operating at higher set temperatures. Conduct periodic maintenance as required.
General Operation
Chamber Loading
Position unit in its ultimate operating location. Keep a minimum of 3" of
airspace around the unit and a minimum of 6" above the unit. The port
hole 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 way for
external temperature measurement of a solution for example.
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.
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 1/10 degree F, or Fahrenheit units. To change Controller functions
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.
Article processing times and temperature uniformity are largely dependent on load density and positioning. Load the
incubator so that the air circulation within the incubator is not impaired. Here are some general guidelines:
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.
Avoid extremely 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 load's suitability, use the set-point recovery time (the time it
takes for the temperature to recover to the original set temperature once the load is placed), as a guide. To reduce
recovery time, reduce load proportionally. When possible, measure large loads or solution temperatures directly with
an ancillary thermometer or probe. Probes can be inserted at the top port.
For best processing performance for a single item, adjust one shelf so that the article is centered in the incubator
chamber.

All units 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.
When at the d-U "Degree Units"
prompt, you can change the
temperature units to F for Farenheit,
or C for Celcius, by using the
buttons.

Upon each initial powering-up, the control may typically overshoot the set temperature by 1 or 2 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.
When the oven exceeds its maximum operating temperature by 3°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.
