INTRODUCTION
Thank you for purchasing a SHEL LAB shaking incubator. We know you have many choices in today’s
competitive marketplace when it comes to constant temperature equipment. We appreciate you choosing
ours. We stand behind our products and will be here if you need us.
READ THIS MANUAL
Failure to follow the guidelines and instructions in this user manual may create a protection
impairment by disabling or interfering with the unit safety features. This can result in injury or death.
Before using the unit, read the manual in its entirety to understand how to install, operate, and
maintain the unit in a safe manner. Ensure all operators are given appropriate training before the unit
begins service.
Keep this manual available for use by all operators.
SAFETY CONSIDERATIONS AND REQUIREMENTS
Follow basic safety precautions, including all national laws, regulations, and local ordinances in your
area regarding the use of this unit. If you have any questions about local requirements, please
contact the appropriate agencies.
SOPs
Because of the range of potential applications this unit can be used for, the operator or their
supervisors must draw up a site-specific standard operating procedure (SOP) covering each
application and associated safety guidelines. This SOP must be written and available to all operators
in a language they understand.
Intended Applications and Locations
SSI incubators are intended for constant temperature, non-humidified microbiological shaking
incubation applications in professional, industrial, and educational environments. These units are not
intended for use at hazardous or household locations.
Power
Your unit and its recommended accessories are designed and tested to meet strict safety
requirements.
•The unit is designed to connect to a power source using the specific power cord type
shipped with the unit.
•Always plug the unit power cord into a protective earth grounded electrical outlet
conforming to national and local electrical codes. If the unit is not grounded properly, parts
such as knobs and controls can conduct electricity and cause serious injury.
•Do not bend the power cord 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 or
altered in any way.
•Use only approved accessories. Do not modify system components. Any alterations or
modifications to your unit not explicitly authorized by the manufacturer can be dangerous
and will void your warranty.

ENGINEERING IMPROVEMENTS
Sheldon Manufacturing continually improves all of its products. As a result, engineering changes and
improvements are made from time to time. Therefore, some changes, modifications, and
improvements may not be covered in this manual. If your unit’s operating characteristics or
appearance differs from those described in this manual, please contact your SHEL LAB dealer or
customer service representative for assistance.

INTRODUCTION
REQUIRED ACCESSORIES
Flask clamps, stationary tube racks, or plate clamps are required to secure samples to the shaking
platform. Clamps and racks must be purchased separately.
The manufacturer offers for sale several types of shaker accessories compatible with this incubator
model. See page 50 for ordering information.

INTRODUCTION
REFERENCE SENSOR DEVICE
Must be purchased separately
A reference sensor device is required for calibrating the unit temperature display.
Reference devices must meet the following standards:
•Accurate to at least 0.1°C
The device should be regularly calibrated, preferably by a third party.
Temperature Probes
Use a digital device with wire thermocouple probes that can be introduced into the unit chamber
through the lid space. Select thermocouples suitable for the application temperature you will be
calibrating at.
Why Probes?
Reference readings taken outside the chamber using wire temperature probes avoid chamber lid
openings. Openings disrupt the chamber temperature. Each disruption requires a minimum 1-hour wait
to allow the atmosphere to re-stabilize before continuing.
No Alcohol or Mercury Thermometers
Alcohol thermometers do not have sufficient accuracy to conduct accurate temperature calibrations.
Never place a mercury thermometer in the unit chamber. Always use thermocouple probes.

INSTALLATION
REQUIRED AMBIENT CONDITIONS
These units are intended for use indoors at room temperatures between 15°C and 30°C (59°F and
86°F), at no greater than 80% Relative Humidity (at 25°C / 77°F). Operating outside these conditions
may adversely affect the unit temperature performance.
When selecting a location to install the unit, consider all environmental conditions that can adversely
impact its temperature performance. These include:
•Proximity to ovens, autoclaves, and any device that produces significant radiant heat
•Heating and cooling vents or other sources of fast-moving air currents
•High-traffic areas
•Direct sunlight
REQUIRED CLEARANCES
These clearances are required to provide airflows for ventilation and cooling.
4 inches (102 mm) of clearance is required on the sides and back.
2.5 inches (60 mm) of headspace clearance is required between the top of the unit and any
overhead partitions.
Ensure that there is sufficient overhead clearance for end-users to fully open the lid.

LIFTING AND HANDLING
The unit is heavy. Use appropriate lifting devices sufficiently rated for these loads. Follow these guidelines
when lifting the unit.
•Lift the unit only from its bottom surface.
•Doors, handles, and knobs are not adequate for lifting or stabilization.
•Restrain the unit completely while lifting or transporting so it cannot tip.
•Remove all moving parts, such as shelves and trays, and lock the door in the closed position
during transfers to prevent shifting and damage.
REMOVING FROM THE PALLET
The unit comes secured to a shipping pallet with ½” hex bolts inserted through the 4 leveling feet
holes on the bottom of the incubator. Use a socket wrench to remove the bolts and release the unit
from the pallet.
LEVELING
Install the 4 leveling feet in the 4 corner holes on the bottom of the unit. The unit must be level and
stable for safe operation.
Note: To prevent damage when moving the unit, turn all 4 leveling feet so that the leg of each foot
sits inside the unit.
