INSTALLATION
Local city, county or other ordinances may govern the use of this equipment. If you have any questions
about local requirements, please contact the appropriate local agency. Installation may be performed by
the end user.
Under normal circumstances this unit is intended for use indoors, at room temperatures and with a supply
voltage that does not vary by more than 10%. Customer service should be contacted for operating
conditions outside of these limits.
3.1 Power Source: The electrical supply circuit to the incubator must conform to all national and
local electrical codes. Consult the incubator‘s serial data plate for the voltage and ampere
requirements before making connection. VOLTAGE SHOULD NOT VARY MORE THAN 10%
FROM THE SERIAL PLATE RATING. This unit is intended for 50/60 Hz application. A separate
circuit is recommended to prevent possible loss of product due to overloading or failure of other
equipment on the same circuit.
3.2 Location: When selecting a site for the incubator, consider all conditions which may affect
performance, such as extreme heat from steam radiators, stoves, ovens, autoclaves, etc. Avoid
direct sun, fast-moving air currents, heating/cooling ducts, and high traffic areas. To ensure air
circulation around the unit allow a minimum of 20 cm between the unit rear and sides and any
walls or partitions which might obstruct free airflow.
3.3 Lifting / Handling: These units are heavy and care should be taken to use appropriate lifting
devices that are sufficiently rated for these loads. Units should only be lifted from their bottom
surfaces. Doors, handles and knobs are not adequate for lifting or stabilization. The unit should
be completely restrained from tipping during lifting or transport. All moving parts and door need
to be positively closed position during transfer to prevent shifting and damage.
3.4 Leveling: The unit must sit level and solidly. Leveling feet are supplied and must be installed in
the four holes in the bottom of the unit. Turn the leveling feet counterclockwise to raise level.
Adjust the foot at each corner until the unit stands level and solid without rocking. If the unit must
be moved, turn the leveling feet in all the way to prevent bending and damage.
3.5 Cleaning: The incubator interior was cleaned at the factory, but not sterilized. Remove all
interior parts and clean with a disinfectant that is appropriate to your application. A thorough
periodic cleaning is strongly recommended.
WARNING: Never clean the unit with alcohol or flammable cleaners with the unit connected to
the electrical supply. Always disconnect the unit from the electrical service when cleaning and
assure all volatile of flammable cleaners are evaporated and dry before reattaching the unit to the
power supply.

CONTROL PANEL OVERVIEW
4.1 Power Switch: The main power I/O (on/off) switch controls all power to the
incubator and must be in the I/ON position before any systems are operational.
4.2 Main Temperature Control: Marked SET TEMPERATURE, the Main
Temperature Control consists of the digital display and UP/DOWN arrow pads for
inputting set point temperatures and calibration.
4.3 Heating Lamp: This pilot lamp in ON when the unit is heating up to set point
and is blinking when controlling temperature at set point.
4.4 Over Temperature Protection (OTP) Safety Thermostat: This thermostat,
labeled SET OVERTEMPERTURE, is completely independent of the Main
Temperature Controller. The OTP guards against any failure of the Main
Temperature Controller that would allow the temperature to rise past the set
point. If temperature rises to the Safety set point, the Safety takes control of the
heating element and allows continued use of the incubator until the problem can
be resolved or service can be arranged. The control is adjusted using a
screwdriver or a small coin.
4.5 Safety Lamp: Located directly below the Safety Thermostat, this pilot lamp
comes ON when the Safety Thermostat is activated. During normal operating
conditions, this light should never come on.
4.6 Shaker Switch: Located to the right of the Safety Thermostat, this switch
engages the oscillation mode of the incubator. To enable oscillation, this switch
must be in the I/ON position. This switch does not have to be On to adjust the
oscillation set point.
4.7 Shaker Controller: This control is labeled RPM and consists of the UP/DOWN
arrow pads and a digital display that shows oscillations per minute. This control
is adjustable from 30 to 400 RPM.

OPERATION
5.1 Check power supply against unit serial plate. They must match.
5.2 Plug service cord into the grounded electrical outlet.
5.3 Push the power switch to the On position, and turn the Safety Thermostat to its maximum
position, clockwise.
5.4 Installing Platform: The platform is positioned by enclosing all corners of the shaking
mechanism within the lips of the platform. This can be done easily by positioning the front two
corners then setting the rest of the tray down. The platform should be shaken by its handles after
placement to confirm that it is firmly in place.
5.5 Set Main Temperature Controller: Enter desired set point temperature. To enter set point mode
on the controller, press either the Up or Down arrow pad one time. The digital display will start to
blink, going from bright to dim. While blinking, the digital display is showing the set point. To
change the set point, use the Up and Down arrow pads. If the arrow pads are not pressed for five
(5) seconds, the display will stop blinking and will read the temperature of the unit. Note that the
High Limit Thermostat should be turned to its maximum position until the unit has stabilized at
desired set point temperature. Allow the incubator at least 5 hours to stabilize.
5.6 Calibration: It is recommended that calibration is done once the unit is installed in its working
environment and has been stabile at set point for several hours. Place a certified reference
thermometer in the chamber by placing it directly inside. Be certain the thermometer is not
touching platform. Allow the temperature to stabilize again until the thermometer reads a
constant value for one hour. Compare the digital display with the reference thermometer. If there
is an unacceptable difference, put the display into calibration mode by pressing both the Up and
Down arrow pads at the same time until the two outside decimal points begin to flash. While the
decimal points are flashing the display can be calibrated by pressing the Up or Down arrow pads
until the display reads the correct value. Allow the incubator temperature to stabilize again, and
recalibrate if necessary.
5.7 Set Over Temperature Protection Safety Thermostat: Once the incubator is stabile at the
desired set point, turn the Safety Thermostat counterclockwise just until the Safety indicator light
turns on. Next, turn the Safety Thermostat clockwise just until the safety indicator light turns off.
Then continue to turn clockwise an additional two small divisions on its scale past the point where
the indicator light went out. This will set the Safety Thermostat at approximately 1C above the
Main Temperature set point.
5.8 Set Oscillation Control: Enter set point mode by pushing and releasing either the UP or Down
arrow pad one time. The display will start to blink on and off showing the RPM set point. Pushing
the UP or DOWN arrow pad will increase or decrease the RPM set point in increments of 1 RPM.
The range for this set point is 30 –400 RPM. If the arrow pads are not pressed for five (5)
seconds the display will stop blinking and revert to displaying the actual RPM. The set point can
be set to 0.0.
Note that for shaker controls to work as described, the door must be completely closed.
There is a door switch that will stop the shaker if the door is opened.

TROUBLESHOOTING
TEMPERATURE
Temperature too high-display and
reference thermometer don‘t match
1/ Controller set too high-see section 5.5.
2/ Controller failed on –call Customer Service.
3/ Wiring error –call Customer Service.
Display reads "HI"
Probe is unplugged, is broken or wire to sensor is broken –trace wire
from display to probe; move wire and watch display to see intermittent
problems.
Chamber temperature spikes over set
point and then settles to set point
Recalibrate –see section 5.6.
Temperature too low-display and
reference thermometer don‘t match
1/ OTP set too low –turn OTP fully clockwise.
2/ Controller set too low –see Section 5.5.
3/ Unit not recovered from door opening –wait for display to stop
changing.
4/ Unit not recovered from power failure or being turned off –incubators
will need 5 hours to warm up and stabilize.
5/ Element failure –see if heating light is on; compare current draw to
data plate.
6/ controller failure –confirm with front panel lights that controller is
calling for heat
7/ OTP failure –confirm with front panel lights that OTP is operating
correctly.
8/ Loose connection –check shadow box for loose connections.
Display reads "LO"
Sensor is plugged in backwards –reverse sensor wires to controller.
Unit will not heat over a temperature that
is below set point
1/ Confirm that amperage and voltage match data plate
2/ Confirm that set point is set high enough –turn OTP all the way
clockwise and see if heating light or safety light comes on.
3/ Check calibration –using independent thermometer, follow
instructions in section 5.6.
Unit will not heat up at all
1/ Verify that controller is asking for heat by looking for controller light –
if pilot light is not on continuously during initial start up, there is a
problem with the controller.
2/ Check amperage –amperage should be virtually at maximum rated
(data plate) amperage.
3/ Do all controller functions work?
4/ Is the OTP set high enough? –for diagnostics, should be fully
clockwise with the pilot light never on.
5/ Has the fuse/circuit breaker blown?
