operators. Ensure that all operators are given appropriate training before the incubator begins
service.
GENERAL SAFETY CONSIDERATIONS
Note: Failure to follow the guidelines and instructions in this manual may create a protection
impairment by disabling or interfering with the unit’s safety features. This can result in injury
or death.
Your Shel Lab CO2 incubator and its recommended accessories are designed and tested to meet
strict safety requirements. Only use this equipment for its intended application. Any alterations or
modifications void the warranty.

Follow all local ordinances in your area regarding the use of this incubator. If you have any
questions about local requirements, please contact the appropriate local agencies.
The power supply for the unit must be an earth grounded electrical outlet that conforms to
national and local electrical codes. If the incubator is not grounded properly, parts such as
knobs and controls can conduct electricity and cause serious injury.
Always use the power cord supplied with the unit or an identical replacement cord.
Avoid damaging the power cord. Do not bend it excessively, step on it, or place heavy
objects on it. A damaged cord can be a shock or fire hazard. Never use a power cord if it is
damaged.

RECEIVING YOUR INCUBATOR
Before leaving our factory, all SCO Incubators are packaged in high-quality shipping materials to
provide protection from transportation-related damage. When the unit departs the factory, safe
delivery becomes the responsibility of the carrier. Damage sustained during transit is not covered
by the incubator warranty.
This makes it important that you inspect your SCO Incubator for concealed loss or damage to its
interior and exterior when receiving it. If you find any damage to the unit, follow the carrier’s
procedure for claiming damage or loss.
The orientation photos on the following pages may serve as a useful visual guide for inspections.
INSPECTING THE SHIPMENT
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.
The unit should come with an Installation and Operation Manual, warranty card, and a Certificate of
Compliance.
Verify that the correct number of the following accessories are present:
Included Accessories
Carefully check all packaging before discarding. Save the shipping carton until you are sure
everything works properly.

RECORDING DATA PLATE INFORMATION
The data plate contains the incubator model number and serial
number. Record this information for future reference.
On the SCO58 the data plate is located on the back of the unit, on
the top right side. On the SCO31 and SCO40 the data plate is
toward the bottom and back of the unit’s right side.

INSTALLATION
AMBIENT CONDITIONS
The SCO Incubators are intended for use indoors, at room temperatures between 15C and 30C
(59F and 86F), at no greater than 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 of these conditions may adversely affect the temperature range
and stability.
LOCATION
When selecting a location to install the incubator, consider all environmental conditions that can
affect the unit’s effective temperature range, uniformity, and stability. For example:
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
Note: Electrical supply to the incubator must conform to all national and local electrical codes.
Always position the unit so that the end-user has access to the power cord.
When selecting a location for an SCO incubator verify that the earth-grounded wall power source
matches the voltage and ampere requirements listed on the incubator data plate. Supplied voltage
must not vary more than 10% from the data plate rating. Damage to the incubator may result
if supplied voltage varies more than 10%.Use a separate circuit to prevent loss of product due to
overloading or circuit failure.
These incubators are intended for a 50/60 Hz application at the following amperages:
If the requirements match the power source, plug the power cord into the earth grounded outlet.
These units are provided with an 115V 2.5m, NEMA 5-20P power supply cord.

INSTALLATION (CONTINUED)
LIFTING
A SCO Incubator 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 SCO Incubator must be level and stable for safe operation. Each incubator ships with four
leveling feet. Insert one leveling foot into each of the four holes in the bottom corners of the
workstation. Adjust the foot at each corner until the workstation stands level and solid without
rocking. To raise a foot, turn it in a counterclockwise direction; to lower a foot, turn it in a clockwise
direction.
ACCESS PORT STOPPER
The SCO58 Incubator is provided with an access port located on the right side of the
unit. The incubator is shipped with one (1) rubber access port stopper. The stopper
should come installed in the port inside the incubation chamber. The stopper should
always be installed in the chamber to obtain the best temperature uniformity and
prevent condensation from forming inside the port. A second stopper may be
installed on the outside of the unit to prevent dust from building up in the port, but is
not required.
