INTRODUCTION
Thank you for purchasing a SHEL LAB 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: The incubators are intended for constant temperature, non-
humidified microbiological incubation applications in professional, industrial, and educational
environments. The 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
REFERENCE SENSOR DEVICE
Must be purchased separately
Temperature Calibrations
If you are not using a third-party service, a reference sensor device is required for calibrating
your unit’s temperature display.
•See the Calibrating the Temperature Display procedure on page 52 for more information.
Device Accuracy
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 Probe
Use a digital device with a wire thermocouple probe that can be introduced into the unit chamber
through the access port or door space. Select a thermocouple suitable for the application temperature
you will be calibrating at.
Why a Probe?
Reference readings taken from outside the chamber using wire temperature probes avoid chamber
door openings. Openings disrupt the chamber temperature. Each disruption requires a minimum 1-hour
wait to allow the chamber 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.
