INTRODUCTION
Thank you for purchasing a SHEL LAB product. 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 for you 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. Keep this manual available for use by all operators. Ensure all
operators are given appropriate training before the unit begins service.
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, CO2-enriched, non-humidified general
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 can be dangerous and void your warranty.

INTRODUCTION
Note: A CO2gas regulator must be purchased separately from the incubator.
CO2GAS SUPPLY
Supply Required!
The incubator must be connected to a carbon dioxide gas supply system in order to establish and
maintain a CO2-enriched incubation chamber atmosphere. The supply can be a building CO2gas system
or a supply cylinder (tank).
Supply Quality
Use medical or food-grade CO2. Use of industrial CO2 risks introducing contaminants into the chamber,
may damage the incubator, and will void the manufacturing defect warranty.
Supply Source and Pressure
The incubator requires 15 – 20 psi of CO2gas pressure at the incubator intake port (labeled CO2 to
Chamber).
Dual Stage Regulator
If connecting to a supply cylinder, use a two-stage CO2pressure regulator. During normal
operations, the incubator uses only small quantities of CO2to maintain the chamber gas
concentration, and precise regulation of the gas input flow is vital for the incubator performance.
Some single-stage regulators have two gauges. Make certain your regulator is a two-stage
regulator. Each cylinder requires a regulator.
Regulator Not Included
See page 59 for ordering information.
Dual Cylinder Connection
The incubator can be connected simultaneously to two CO2supply cylinders.
The unit automatically switches drawing from one cylinder to the other when
the first cylinder runs out of CO2. Two gas regulators are required for this
configuration.

INTRODUCTION
REFERENCE SENSOR DEVICES
Must be purchased separately
Reference sensor devices or a combined device are required for calibrating the
incubator temperature and CO2displays.
Reference devices must meet the following standards:
•Accurate to at least 0.1°C
•Accurate to at least 0.1% CO2
The devices should be regularly calibrated, preferably by a third party.
Temperature Probes
For temperature, use a digital device with wire thermocouple probes that can be
introduced into the incubation chamber through the unit access port. Select
thermocouples suitable for the application temperature you will be calibrating at.
CO2 Sampling
For best CO2accuracy, use a digital gas analyzer with sample tubing connecting to
the incubator CO2sample port. The barbed adapter gas fitting on the sample port
connects to 3/16-inch (4.76mm) inner diameter (ID), 5/16-inch (7.94mm) outside
diameter (OD) tubing.
Why Probes and Tubing?
Reference readings taken outside the chamber using wire temperature probes and
CO2drawn through the sample port avoid chamber door openings. Openings disrupt
the chamber temperature and CO2 concentration level. 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 incubation
chamber! Always use thermocouple probes.

POWER SOURCE REQUIREMENTS
When selecting a location for the unit, verify each of the following requirements is satisfied.
Power Source
The power source for the unit must match the voltage and match or exceed the ampere
requirements listed on the unit data plate. These units are intended for 110 – 120V 50/60 Hz
applications at 12 amps.
•Supplied voltage must not vary more than 10% from the data plate rating. Damage to the
unit may result if the supplied voltage varies more than 10%.
•The wall power source must be protective earth grounded.
•Use a separate circuit to prevent loss of the unit due to overloading or circuit failure.
•The recommended wall circuit breakers for these units are 15 amps.
•The wall power source must conform to all national and local electrical codes.
Power Cord
The unit must be positioned so that all users can quickly unplug the cord in the event of an
emergency.
•The unit comes provided with a 125 volt, 15Amp, 9ft 5 in (2.86m) NEMA 5-15P power cord.
•Always use this cord or an identical replacement.
Fuses
The unit ships with a fuse installed in the power cord inlet.
•The fuse must be installed and intact for the unit to operate.
•Always find and fix the cause of a blown fuse prior to putting the unit back into operation.

INSTALLATION
LIFTING AND HANDLING
The unit is heavy. Use appropriate lifting devices that are 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 doors in the closed position
during transfers to prevent shifting and damage.
LEVELING
Install the 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 four leveling feet so that the leg of each
foot sits inside the unit.
INSTALL INCUBATOR IN LOCATION
Install the unit in a workspace location that meets the criteria discussed in the previous entries of the
Installation 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. The manufacturer 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.

INSTALLATION
INSTALLATION -CLEAN AND DISINFECT
Cleaning and disinfecting the incubation chamber and shelving components now reduces the risk
of contamination. The chamber was cleaned and disinfected at the factory, however, the unit may
have been exposed to contaminants during shipping.
•Remove all protective wrappings from shelving components prior to cleaning.
•See the Cleaning and Disinfecting entry on page 45 for information on how to clean and
disinfect without damaging the incubator or its components.
SHELVING INSTALLATION
Install the shelf standard rails.
a. Align the keyhole slot of the standard with the mounting
peg on the side of the chamber wall.
b. Mount the standard on the peg.
Install the shelf slides.
a. Insert the shelf slide into the shelf standard using a
rocking motion.
•The shelf slide will sit level when correctly installed.
Place the shelves.
a. Slide into position.
