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 between 5and
40C, at no greater than 80% Relative Humidity (at 25C) 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.
This unit should remain upright for 24 hours prior to turning on. This will allow the oil settle to in
the refrigeration compressor.
2.1 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, cycle
wattage 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.
2.2 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 20cm
between incubator rear and sides and any walls, partitions or obstructions to free airflow.
2.3 Lifting / Handling: This unit is 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, such as shelves and trays should be removed and doors need to be
positively locked in the closed position during transfer to prevent shifting and damage.
2.4 Leveling: The unit must sit level and solidly. Turn the leveling feet counterclockwise to
raise level. If the unit must be moved, turn the leveling feet in all the way to prevent
bending and damage.
2.5 Cleaning: The incubator interior was cleaned at the factory, but not sterilized. Remove
all interior parts and clean with a disinfectant that is appropriate for your application. DO
NOT USE abrasives as this will damage the incubators interior. DO NOT USE spray
cleaners that might leak through opening and cracks and get on electrical parts or that
may contain solvents that will harm the coatings. 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 or flammable cleaners are evaporated and dry
before reattaching the unit to the power supply.

CONTROL PANEL OVERVIEW
3.1 Power Switch: The main power I/O (on/off) switch controls all
power to the unit and must be in the I/ON position before any
systems are operational.
3.2 Main Temperature Control: This control is marked SET
TEMPERATURE and consists of the digital display and
UP/DOWN arrow pads for inputting set point temperatures and
calibration.
3.3 Heating Lamp: This pilot lamp is marked TEMPERATURE
ACTIVATED and is ON when the unit is heating up to set point
and is blinking when controlling temperature at set point.
3.4 Overtemperature Thermostat: This control is marked SET
OVERTEMPERATURE and is completely independent of the
Main controller. It acts as an override in the event that the Main
control fails in the ON position.
3.5 Overtemperature Light: This pilot lamp is marked
OVERTEMPERATURE ACTIVATED and is on when the
thermostat has been activated. Under normal operating
conditions, this pilot light should never be on.
3.6 Circuit Breaker: (Non-CE units) Adjacent to the power cord the
circuit breaker is an added measure of protection against power
source variations that if tripped, must be reset by pushing in the
button once the reason for interruption has been cleared.
3.7 Fuse: (CE units only) Located at the back of the unit within the
power inlet, the fuse is an added measure of protection against
power source variations that, if blown, must be replaced once the
reason for the interruption has been cleared. Note that the unit
will not power up unless the fuse is in place.

OPERATION
4.1 Check power supply against unit serial plate. They must match.
4.2 Plug service cord into the grounded electrical outlet.
4.3 Push the power switch to the I/On position, and turn the Overtemperature Thermostat to
its maximum position, clockwise using a coin or flat edged tool.
4.4 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 Overtemperature
Thermostat should be turned to its maximum position, (clockwise) until the unit has
stabilized at desired set point temperature. Allow the incubator at least 24 hours to
stabilize.
4.5 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. Be certain the thermometer is not
touching any shelving. 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.
4.6 Set Overtemperature Thermostat: As mentioned previously, the Overtemperature
Thermostat should be initially set to its maximum position, (clockwise), to allow the unit
to stabilize. Once the incubator is stabile at the desired set point, turn the
Overtemperature Thermostat counterclockwise until the OVERTEMPERATURE
ACTIVATED light turns on. Next, turn the Thermostat clockwise just until the light turns
off. Then turn the Thermostat clockwise 1/16 of an inch past the point where the light
went out. This will set the Overtemperature Thermostat at approximately 1C above
main Temperature set point.
4.7 Accessory Outlet: This unit has been supplied with a 1 amp accessory outlet inside
the chamber to provide power for equipment such as magnetic stirrers, rockers, etc. Be
certain the apparatus draws 1 amp or less. The power switch on the front panel controls
power to the outlet. Note that the apparatus may provide additional heat that could
affect the temperature range of this incubator. It is recommended that testing be done
with the incubator and any accessory equipment to insure that the desired operating
conditions can be met.

MAINTENANCE
Note: Prior to performing maintenance and/or service on this incubator, disconnect the unit from
the power supply.
5.1 Cleaning: Cleaning and decontamination are recommended on a regular basis. To
prepare the unit for cleaning, disconnect the power cord and remove all interior parts,
such as shelves, trays, etc.
First clean the chamber with soap and water, rinse and let dry. To decontaminate use a
solution that is appropriate for your application. DO NOT USE abrasives as this can
damage the chamber interior. DO NOT USE spray cleaners that might leak through
openings and cracks and get on electrical parts or that may contain solvents that will
harm the coatings. NEVER USE acids, chemical thinner, gasoline, benzene or like
chemicals for cleaning the unit. Boiling water and benzene can deform and damage
plastic parts.
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 or flammable cleaners are evaporates and dry
before reattaching the unit to the power supply.
5.2 Compressor Compartments: Located at the back and bottom of the unit, the
compressor compartment can collect dust that will inhibit proper air flow. This
compartment should be vacuumed out at least once every six (6) months to ensure
maximum efficiency.
5.3 Defrosting: Generally defrosting should not be necessary. If ice build-up occurs it is
usually attributed to open containers, loose closures or frequent door openings causing
excessive moisture to build up in the chamber. Try to eliminate these as possibilities.
To defrost, remove all items from the chamber and let the unit stand with the door open
and the POWER OFF. Once frost is gone, empty drip tray, wipe the chamber dry and
power up the unit.
5.4 Storage: If the incubator is to be shut down for storage or transport, remove all items,
drip tray and shelves and be certain the chamber is dry. Screw in the leveling feet.
Review section 2.3, Lifting / Handling for transport instructions.
5.5 There is no maintenance required on electrical components. If the unit fails to operate
as specified, please review section 6 Troubleshooting, prior to calling for technical
service.
