These units are general purpose Biochemical Oxygen Demand (BOD) incubators 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. These units are 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.
1.1 Inspection: The carrier, when accepting shipment, also accepts responsibility for safe
delivery and is liable for loss or damage. On delivery, inspect for visible 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 Service representative for
authorization. Supply data plate information including model number and serial number.
For information on where to contact Customer Service, please see the manual cover.
1.4 Accessories: Verify that all of the equipment indicated on the packing slip is included
with the unit. Carefully inspect all packaging before discarding. The SRI20 (LI20)
incubators are supplied with four (4) shelves.
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
This unit should remain upright for 24 hours prior to operating to allow the oil in the refrigeration
compressor to settle.
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.
2.1 Power Source: Before connecting the unit to the power source, the electrical supply circuit must
conform to all national and local electrical codes. The power source must match the cycle and
ampere requirements as noted on the data plate located on the side of the incubator. This unit is
intended for 50/60 HZ application. VOLTAGE SHOULD NOT VARY BY MORE THAN 10%
FROM THE DATA PLATE RATING. A separate circuit is recommended to prevent possible loss
of product due to the overloading or failure of other equipment on the same circuit.
2.2 Location: When selecting a site for the incubator, consider all conditions that may affect
performance, such as extreme heat from radiators, stoves, ovens, autoclaves, etc. Avoid direct
sun, fast moving air currents, heating and cooling ducts, and high traffic areas. To ensure air
circulation around the unit, allow a minimum of 20cm (8”) between incubator and any walls or
partitions that may obstruct free airflow.
2.3 Lifting and 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, 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 the
level. If the unit must be moved, turn the leveling feet in all the way to prevent bending and
damage.
2.5 Cleaning: The unit chamber should be cleaned and disinfected prior to use. Remove all of the
interior parts, if assembled, and clean thoroughly, including all corners using a suitable disinfectant
that is appropriate to your application. DO NOT use spray cleaners that might leak through
openings and cracks and get on electrical components, or that may contain solvents that will harm
coatings. DO NOT use chlorine-based bleaches or abrasives as they will damage the stainless
steel interior. Regular periodic cleaning is required. Special care should be taken when cleaning
around sensing heads to prevent damage.
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.
