INSTALLATION
AMBIENT CONDITIONS
The SCO6AD is 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 the incubator temperature
performance, including its effective operating range, stability, and uniformity.
POWER SOURCE
Always position the unit so that the end-user has access to the power cord and can quickly unplug
it from the wall in the event of an emergency.
When choosing a location for the incubator, check that the voltage and ampere requirements on the
incubator data plate match that of the wall power source. The source must be an earth grounded
outlet. 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.
The SCO6AD comes provided with a 125 volt 9ft 5 in (2.86m) NEMA 5-15P power cord.
The required fuse for the incubator is 12.5 Amps.
The incubator is intended for a 50/60 Hz application at 12 Amps.
Note: Electrical supply to the incubator must conform to all national and local electrical codes.
ENVIRONMENTAL FACTORS
When selecting a location to install the incubator, consider all environmental conditions that can
affect 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

INSTALLATION (CONTINUED)
LIFTING
The 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 or transporting the unit.
LEVELING
Make sure that the incubator is level and stable. Each incubator ships with four leveling feet. Insert
one leveling foot into each of the four holes in the bottom corners of the incubator. Stand the
incubator upright. Then, adjust the foot at each corner until the incubator 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.
Note: To prevent damage to the feet when moving the incubator, turn each of the four leveling feet
completely clockwise.

INSTALLATION (CONTINUED)
CONNECT THE CO
Note: Always use medical grade CO2. Use of non-medical grade CO2 risks introducing
contaminants into the chamber, may damage the incubator, and will void the incubator’s
warranty. Failure to use the in-line HEPA filter also voids the warranty.
Always install the in-line HEPA filter (Part Number 2800525) provided with the SCO6AD tubing
kit between the gas source and the incubator. The filter is directional. Make sure that it is installed
correctly for the flow direction (see page 41). Failure to install the filter will decrease the lifespan of
the SCO6AD, and risks allowing contaminants into the incubation chamber.
During normal operations the incubator uses only small quantities of CO2. Precise regulation of the
gas input flow is vital for the incubator performance. Always use a two-stage CO2 pressure
regulator. Some single-stage regulators have 2 gauges. Make certain your regulator is a twostage regulator.
Connect the CO2 regulator to a medical grade CO2 cylinder or source.
Set the CO2 cylinder regulator or wall source regulator to 15 - 20 Pounds per Square
Inch (psi). Do not exceed 20 psi.
Please see the Pressure Units Conversion table on page 43 in the Unit Specifications section for
the formulas for converting psi into other units of pressure measurement.

INSTALLATION (CONTINUED)
INSTALLATION CLEANING AND DISINFECTION
If required by your laboratory protocol, clean and manually disinfect the incubator chamber and
shelving components. Cleaning and disinfecting during installation reduces the risk of
contamination. The chamber and shelving were cleaned at the factory, and a decontamination
cycle was run to verify the cycle functionality. However, Sheldon Manufacturing cannot guarantee
that the incubator was not exposed to contaminants during shipping.
Please see the Cleaning and Disinfecting entry on page 39 in the User Maintenance section for
information on how to clean and disinfect without damaging the incubator or its components. A
decontamination cycle will be run as part of the Incubator setup in the Operation section.
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.
SHELVING INSTALLATION
Remove all protective wrappings from shelving components prior to installing:
Install the shelf standards.
a. Align the keyhole slot of the standard with the mounting
peg on the side of the chamber wall.
b. Mount the shelf standard.
Install the shelf slides.
a. Insert the shelf slide into the shelf standard using a
rocking motion.
b. The shelf slide will sit level when correctly
installed.
Install the shelves.
a. Slide into position with the bent ends facing
up in the back and down in the front.
Install the humidity pan.
a. Place the copper anti-microbial token in the humidity pan.
b. Secure the token using the clip on the bottom of the pan.
c. Place the pan on the chamber floor.
