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.

INTRODUCTION
Temperature
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 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.
