RECEIVING YOUR INCUBATOR
When an incubator leaves the factory, safe delivery becomes the responsibility of the carrier.
Damage sustained during transit is not covered by the manufacturing defect warranty. When you
receive your incubator inspect it for concealed loss or damage to the interior and exterior. If you find
damage, follow the carrier’s procedure for claiming damage or loss.
INSPECTING THE SHIPMENT
Before leaving the factory, SMI incubators are packaged in high-quality shipping materials to
provide protection from transportation-related damage.
Carefully inspect the shipping carton for damage. Report any damage to the carrier service that
delivered the incubator. If the carton is not damaged, open the carton and remove the contents.
Carefully check all packaging before discarding. Save the shipping carton until you are certain that
the unit and its accessories function properly.
Inspect the incubator for damage. The orientation photos on the pages following this one can serve
as useful visual references.
The unit should come with an Installation and Operation Manual and a Certificate of Compliance.
Verify that the correct number of accessory items are present in the ship kit.
Accessory Items
Each unit is provided with a 115 volt, 15 Amp, 9ft 5 in (2.86m) NEMA 5-15P power cord.

RECORDING DATA PLATE INFORMATION
The data plate contains the incubator model number and serial number. Record this information
for future reference.
The data plate is located on top right corner of the incubator door, on the interior chamber side.
Date Plate Information
REFERENCE SENSOR DEVICE
A reference sensor device must be purchased separately for performing temperature display
accuracy verifications or calibrations.
A reference devices must be accurate to at least 0.1°C. The device should be regularly calibrated,
preferably by a third party. For best results, use a digital device with a wired-connected temperature
sensing probe that can be placed in the incubation chamber through the unit access port, while
leaving the device and its display outside the unit. For example: a wire thermocouple probe.
Reference readings that avoid chamber door openings during verification and calibration eliminates
a subsequent hour-long wait for the chamber temperature to re-stabilize before proceeding.
Select probes suitable for the application temperature you will be calibrating or verifying the
incubator displays at.
Alcohol thermometers do not have sufficient accuracy for conducting accurate temperature
verifications and calibrations. Do not use a mercury thermometer. Never place a mercury
thermometer in the incubation chamber.

INSTALLATION
REQUIRED AMBIENT CONDITIONS
SMI incubators are intended for use indoors at room temperatures between 15C and 30C (59F
and 86F), at no greater than an ambient 80% Relative Humidity (at 25C / 77F). Allow a
minimum of 4 inches (10cm) between the incubator and walls or partitions, and 2 inches (5cm) of
clearance above the top of the incubator for unobstructed airflow.
Operating the unit outside these conditions may adversely affect its temperature range and stability.
For conditions outside of those listed above, please contact your distributor to explore other unit
options suited to your laboratory or production environment.
ENVIRONMENTAL FACTORS
When selecting a location to install the incubator, consider all environmental conditions that can
affect the unit temperature performance. For example:
Proximity to ovens, autoclaves, and any device that produces significant radiant heat
Heating and cooling ducts, or other sources of fast-moving air currents
High-traffic areas
Direct sunlight
POWER SOURCE REQUIREMENTS
When selecting a location for the unit, verify that each of the following requirements are satisfied.
The required circuit amperage to support these units is 15 amps Wall power sources must match
the voltage and ampere requirements listed on the unit data plate. These units are intended for 110
– 120 VAC 50/60 Hz applications at the following amperages: SMI31 12.0 Amps; SMI39 14.5
Amps.
The wall power sources must conform to all national and local electrical codes.
Wall power sources must be protective earth grounded. Use a separate circuit to prevent
loss of product due to overloading or circuit failure.
Supplied voltage must not vary more than 10% from the data plate rating. Damage to
the unit may result if supplied voltage varies more than 10%.
The unit is provided with a 115 volt 15 Amp, 9ft 5 in (2.86m) NEMA 5-15P power cord.
The unit must be positioned so that all end-users can quickly unplug the power cord in the

LIFTING AND HANDLING
The unit should only be lifted by its bottom surfaces using proper heavy lifting machinery such as, a
forklift or pallet jack. Handles and knobs are inadequate for lifting or stabilization. The unit should
be completely restrained from tipping during lifting. Transporting the unit while lifted is not
recommended and may be hazardous. Remove all moving parts such as, shelves and trays, and
secure the door in the closed position prior to lifting the unit.
Do not attempt to move the unit while in operation or before the unit has cooled.
LEVELING
The unit must be level and stable for safe operation. Each unit ships with four leveling feet.
1. Insert one leveling foot into each of the four holes in the bottom corners of the unit.
2. Adjust the foot at each corner until the unit stands level and solid without rocking. To raise
a foot, turn it in a counterclockwise direction.
3. To lower a foot, turn it in a clockwise direction.
To prevent damage to the feet while in transport turn all feet to the maximum counterclockwise
position.
INSTALL THE INCUBATOR
Place the unit in a workspace location that meets the criteria discussed in the previous entries of
the Installation section.
ACCESS PORT CAP
SMI incubators are provided with a plastic cap for the access port on the left side of the incubation
chamber. Always leave this cap in place, except when introducing probes into the chamber for
temperature calibrations or verifications. Removing the cap during normal operations can adversely
impact temperature stability and uniformity.
DEIONIZED AND DISTILLED WATER
Do not use deionized water to clean or humidify the incubator. Use of deionized water may
corrode metal surfaces and voids the warranty. Sheldon Manufacturing recommends the use of
distilled water in the resistance range of 50K Ohm/cm to 1M Ohm/cm, or a conductivity range of
20.0 uS/cm to 1.0 uS/cm, for cleaning and humidifying applications.
