Use the following guidelines to prepare the unit
for regular use. The guidelines illustrate how to
use all the features of your incubator. Your
laboratory protocol will determine your actual use
of these features.
1. Turn the unit on.
See “Turning the Unit On” below on this
page.
2. Set the chamber to the desired temperature
and wait for the chamber temperature to
stabilize.
See “Setting the Chamber Temperature” on
page 11.
3. Calibrate the main temperature control.
At any time, use the following features when
appropriate.
Turn the shaking mechanism on and adjust
the speed of the shaking mechanism.
See on page 11.
Set the Over Temperature Protection (OTP)
to guard your samples from inadvertent overheating.
See on page 12.
To account for the weight of different sample
loads, you will need to adjust the number of
counterweights being used.
See on page 12.
To adjust the movement of the shaking
mechanism from vigorous to gentle, you will
need to adjust the shaking stroke and
counterweight position.
See on page 13.
Turning the Unit On
The unit is equipped with an On/OFF switch that
controls power to the entire unit. The switch is lit
by a green light when the power is on.
3. When you turn the unit on for the first time,
use a screwdriver or coin to turn the Safety Temp knob fully clockwise to its maximum
position. This deactivates the OverTemperature Protection (OTP) feature. For
more information on the OTP, see on page
12.
Setting the Chamber
Temperature
You raise or lower the temperature in the
chamber using the main temperature controller,
which consists of a digital display and UP and
DOWN arrow pads marked Set Temp.
To set the chamber temperature
To set temperature, press and release either up or
down key and display will blink. Then, press and
hold either up or down key to scroll up or down for
set point.
When you press either the Up or Down arrow key,
the display starts to blink from bright to dim and
shows the temperature set point, which is the
temperature to which the unit will stabilize.
The incubator accepts the new set point after you
release the arrow pads for 5 seconds. At that time,
the display stops blinking and indicates the
present chamber temperature.
After setting the chamber temperature, wait at
least 1 hour for the chamber temperature to
stabilize to ambient conditions. To achieve
maximum temperature stability, wait 24 hours
before you begin using the unit.
Calibrating the Main
Temperature Control
Calibrating your unit ensures that the temperature
inside the incubator matches the temperature reading
of a certified reference thermometer.
We recommend that you calibrate your unit once it has
been installed in its working environment and the
chamber temperature has been stable at the set point
for several hours.
You should calibrate your unit at or as close to the
temperature set point as possible. To maximize your
results, calibrate the unit each time you operate the unit
at a new temperature.
Use only a Certified (NIST) temperature-measuring
device to calibrate your unit.
To verify that your unit needs calibration
1. Be sure the temperature within the chamber has
stabilized at the set point for several hours.
2. Insert a certified reference thermometer through
the access porthole. To attain the best calibration,
place the thermometer as close to the location of
the samples. Be sure the thermometer is not
touching any shelving.
3. Allow the reference thermometer to stabilize until it
displays a constant value for one hour.
4. Compare the temperatures displayed by the
incubator and reference thermometer.
If they match, you do not need to calibrate your unit for
that temperature. If they do not match, you need to
calibrate your unit.
To calibrate your unit
1. Simultaneously press and hold the Set Temp Up
and Down arrow keys.
After approximately 5 seconds, the temperature reading
will blink off and on. Release the Up and Down arrow
key.
2. While the display is blinking, press the Up or Down
arrow keys to select the temperature that matches
your reference thermometer. When you hold an
arrow key, the display scrolls through the
temperature settings.
The incubator accepts the new temperature reading
after you release the arrow pads for 5 seconds. At that
time, the display stops blinking.
3. For best results, re-verify the calibration after
the unit has remained on for 24 hours and its
temperature has varied by no more than + 1
C.
Setting the Shaker Speed
Your unit is equipped with a shaker mechanism that
provides maximum oxygenation of your samples.
You control the shaking mechanism using the shaker
control—which consists of a digital display that shows
RPM (rotations per minute) in increments of 1 and
UP/DOWN arrow pads marked Set RPM—and the
RPM switch.
To turn the shaking mechanism on
1. Be sure the door is completely closed.
2. Push the RPM switch to the On (I) position.
The shaker mechanism will increase the speed up
to the current set point, which is the speed at
which the unit will rotate per minute. Note that the
shaker motor runs continuously as long the RPM
switch is On (I).
To adjust the shaker speed (RPM)
1. Press either the Up or Down arrow key once. The
display starts to blink from bright to dim and shows
the RPM set point.
2. Press the Up or Down arrow keys to select the
desired RPM.
The incubator accepts the new set point after you
release the arrow pads for 5 seconds. At that time,
the display stops blinking and indicates the
present RPM.
Even if you turn the RPM switch off (O), the
controller remembers the last RPM value used.
You can adjust the movement of the shaking
mechanism. See page 13.
Using the incubator’s timer, you can run the shaker
platform at a preset RPM for a preset time. The timer
can be set at intervals of one (1) minute up to a
maximum of a 999 (16 hours 39 minutes).
Upon completion of the timing cycle, the TIMER alarm
LIGHT will turn ON and an alarm will sound.
You can interrupt the timer if you need to access the
shaking platform before the timer completes.
To start a timed shaking process
1. Turn the TIMER switch to the ON (I) position.
2. Press the set timer up or down arrow key once.
The display starts to blink off and on and shows
the current set time. Press the up or down arrow
to select the desired time.
Approximately five seconds after you release the Up or
Down arrow keys, the display stops flashing and the
timing interval begins.
To interrupt a timed shaking process
Turn the TIMER switch and the RPM switch
1. For best results, calibrate your unit before you set
the safety thermostat.
See “Calibrating the Main Temperature Control” on
page 11.
2. Be sure the temperature within the chamber has
stabilized at the set point for several hours.
3. Using a screw driver or a small coin, turn the
Safety Temp knob counterclockwise until the
Temp alarm light turns on and off, which
designates that your OTP has been activated.
The light will cycle on and off as the element is
trying to energize on and off.
4. Turn the Safety Temp knob slightly clockwise until
the Temp alarm light turns off.
NOTE: Temp Alarm will only sound off when
temp overshoot 1°C from setpoint.
The OTP is now set at approximately 1C above the
main temperature set point. If, for any reason, the
chamber temperature rises to the safety thermostat
setting, the Temp alarm will go off and the heating
element will not raise the chamber temperature any
further.
to the OFF (O) position.
Adding or Removing
Wait for the mechanism to come to a complete stop
before entering the chamber.
To restart an interrupted timed shaking
process
Turn the RPM and TIMER switch to the ON (I)
position.
Setting the Safety
Temperature Alarm
You can prevent the chamber temperature from
inadvertent over-heating by using the unit’s OverTemperature Protection (OTP), which consists of:
a thermostat independent of the main temperature
control.
a knob, marked Safety Temp, to set the safety
temperature threshold. The numbered scale
around the knob is for reference only and does not
correspond to any temperature points.
an alarm, marked Temp, that sounds if the
temperature exceeds the user-defined
temperature threshold.
Counterweights
To allow the smoothest operation of the shaker, you
should adjust the number of counterweights used
based on the weight of the load.
To add or remove counterweights
1. Unplug the unit from its power source. When the
shaker mechanism comes to a complete halt,
remove the sample tray.
2. Rotate the counterweight platform until the
counterweight appears. Remove the wing nuts
and add or remove counterweights according to
the total weight of your samples, as shown below.
You can adjust the shaker movement to gentle,
moderate, or vigorous shaking. Which shaking
movement you use depends on the oxygenation needs
and cell strength of your samples.
When you change the stroke of the shaker mechanism,
you also need to adjust the counterbalance position.
Always disconnect the unit from its power supply
before attempting this procedure. Serious injury
can result if the drive plate operates accidentally.
To adjust the shaker movement
1. Unplug the unit from its power source. Remove
the sample tray.
2. Rotate the counterweight platform until the stoke
adjuster is in full view. Remove the wing nut and
adjust the arm to any of the available options.
3. Re-add the wing nut.

procedures you use, always keep the following
guidelines in mind when decontaminating your unit:
Use cleaning materials known to be
compatible with your unit. If any questions
arise about compatibility issues, contact
Customer Service, see page-21.
Clean and disinfect the incubator interior on a
regular basis. If the inside of your incubator
smells strangely or contains rust, mold, or dirt,
you need to clean your incubator more
frequently
Dust the outside walls of the incubator at least
every two months.
For incubators placed on the floor, move the
incubator every two months to clean and
disinfect the floor below.
Clean all gaskets and hinges every month.
Do not use chlorine-based bleaches or
cleaners with abrasives as they will corrode
and pit the interior of you incubator and any
other stainless steel surfaces. Use only nonabrasive cleaners.
Do not use spray cleaners that might leak
through openings and cracks and get on
electrical parts. These cleaners may also
contain solvents that will harm the coatings.
Do not use hard tools such as metal wire
brushes or steel wool. Use only soft tools such
as plastic brushes.
Do not depend on the use of antibiotics to
maintain completely sterile conditions, as this is
an inadequate technique for sterilization.
Instead, use the aseptic techniques described
in this section to maintain sterile conditions in
the incubator.
You can use an autoclave to decontaminate
stainless steel parts by following the
manufacturer’s instructions.
Otherwise, wash all parts and surfaces with
soap and water to remove any organic material.
Disinfect the parts with a 70% alcohol solution.
