UNIT SPECIFICATIONS
SCHEMATICS
This unit is a general purpose Biochemical Oxygen Demand (BOD) incubator for
professional, industrial or educational use where the preparation or testing of
materials is done at approximately atmospheric pressure and no flammable,
volatile or combustible materials are being heated. This unit is not intended for
hazardous or household locations or use.
RECEIVING AND INSPECTION
Your satisfaction and safety require a complete understanding of this unit. Read
the instructions thoroughly and be sure all operators are given adequate training
before attempting to put the unit in service. NOTE: This equipment must be used
only for its intended application; any alterations or modifications will void your
warranty.

exterior damage, note and describe on the freight bill any damage found, and
enter your claim on the form supplied by the carrier.
1.2 Inspect for concealed loss or damage on the unit itself, both interior and exterior.
If necessary, the carrier will arrange for official inspection to substantiate your
claim.
1.3 Return Shipment: Save the shipping crate until you are sure all is well. If for
any reason you must return the unit, first contact your customer representative
for authorization. Supply nameplate data, including model number and serial
number. Please see the manual cover for information on where to contact

WARNING: Never use this unit for the growth, cultivation, incubation or storage
of fruit flies (drosophila melanogaster). This unit is not designed for use with
fruit flies. Improper use of this unit, including use with fruit flies, will void any
warranty. Other units are specifically manufactured for fruit fly application, and
you should consult your dealer or the manufacturer in order to identify another
model suitable for your application.
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 40C, at no greater than 80% Relative Humidity (at 25C) 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.
