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 end-users are given appropriate training before the unit

begins service.

Keep this manual available for use by all end-users.

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 end-user 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 end-users

in a language they understand.

Intended Applications and Locations

This incubator is intended for constant temperature, humidified microbiological incubation

applications in professional, industrial, and educational environments. The unit is 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 are not covered by the manufacturing defect warranty.

INTRODUCTION

Note: A CO2gas regulator must be purchased separately from the incubator.

Note: Each incubation chamber in an SCO10A must have its own CO2supply.

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. The use of industrial CO2 risks introducing contaminants into the

chamber, may damage the incubator, and is not covered by 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, always use a dual-stage CO2pressure regulator. During normal

operations, the incubator injects 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 dual-stage

regulator.

Regulator Not Included

See page 58 for ordering information.

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 a 3/16-inch (4.76 mm) inner diameter (ID), 5/16-inch (7.94 mm) 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.
