INTRODUCTION Thank you for choosing a water jacket incubator. These units are not intended for use at hazardous or household locations. Before you use the unit, read this entire manual carefully to understand how to install, operate, and maintain the unit in a safe manner. Your satisfaction with the unit will be maximized as you read about its safety and operational features. Keep this manual on-hand so it can be used by all operators of the unit.
1 Section RECEIVING AND INSPECTION IMPORTANT: READ THIS INSTRUCTION MANUAL IMMEDIATELY! Your satisfaction and safety require a complete understanding of this unit, including its proper function and operational characteristics. Be sure operators are given adequate training before attempting to put the unit in service. NOTE: This equipment must be used only for its intended application; any alterations or modifications will void your warranty. 1.
2 Section GRAPHIC SYMBOLS Your incubator has been provided with a display of graphic symbols which is designed to help in identifying the use and function of the available user adjustable components. 2.1 Indicates that you should consult your manual for further description or discussion of a control or user item. 2.2 Indicates "Temperature". 2.3 Indicates "Over-temperature safety". 2.4 C Indicates "Degrees Centigrade". 2.5 CO2 Indicates "Carbon Dioxide". 2.
3 Section INSTALLATION Local city, county, or other ordinances may govern the use of this equipment. If you have any questions about local requirements, please contact the appropriate local agency. Installation may be performed by the end user. Under normal circumstances this unit is intended for use indoors, at room temperatures between 5 and 40C, at no greater than 80% Relative Humidity (at 25) and with a supply voltage that does not vary by more than 10%.
Regardless of the decontamination procedure used, certain precautions will need to be taken: A. B. Always disconnect the unit from the electrical service when cleaning. Assure all volatile or flammable cleaners are evaporated and dry before reconnecting the unit to the power supply. Special care should be taken when cleaning around sensing heads to prevent damage. C. If you use chlorine-based bleaches or abrasive cleaners this will modify the stainless steel interior finish.
3.6 Shelves and Interior Parts: Shelving, shelf supports and a humidity pan are supplied with each unit. See Figure 1, for proper placement of these accessories.

Click on this section: To use your SHEL LAB CO2 Incubator USB features, you need to download the software by clicking on the image below.
4 Section CONTROL PANEL OVERVIEW All controls are located on the front panel. Units with a detachable cord have a fused inlet located at the top rear of the control panel. This inlet has a recessed male plug, fuse and an EMI filtering system designed to filter out electrical interference. This inlet also prevents any internally generated interference from feeding out to the power grid. 4.
injection rate and limit values to that which was input by the operator. 4.7 Injection Light: This pilot lamp is on whenever the CO2 controller is injecting CO2 into the chamber. 4.8 Humidity Display: This digital display is marked %RH and indicates the relative humidity in the chamber. 4.9 Datalog Communications Interface: This controller provides six (6) parameters to externally log data of all the front panel displays.
5 Section OPERATION READ THIS SECTION IN ITS ENTIRETY BEFORE ATTEMPTING OPERATION! IMPORTANT: In order to ensure the proper operation of this incubator, it is essential that you regularly verify the accuracy of the temperature and CO2 controls. Temperature can be confirmed by use of a thermometer inside of the chamber. CO2 can be confirmed with the use of a Fyrite Gas Analyzer or other equipment such as a gas chromatograph. These must be checked at least on a weekly basis.
humidity is obtained. Do not use plastic, glass or other metals. Only 300 series stainless metals are acceptable for this reservoir pan. Do not use corrosive chemicals including copper sulphate or chlorine in the pan or chamber as damage may occur. Use Distilled Water Only. DO NOT USE DEIONIZED WATER! Use of disinfecting chemicals in the pan can change the surface tension of the reservoir water thus preventing evaporation and proper humidification of the chamber.
5.9 CO2 Supply System and Control System: The CO2 system is rated for pressures between 15 to 20 PSI which should never be exceeded at any time. Prior to any attempt to hook up or run the CO2 control system, the water jacket must be filled and the temperatures adjusted as noted in section 5.7. Figure 3 A. B. C. D. The CO2 inlet fittings are located at the back of the unit near the top (see figure three). They are marked CO2 TO CHAMBER. You have the option of using one or two tanks.
E. 5.10 5.11 The micro processor CO2 control system interprets the information from the CO2 sensor, displays the CO2 concentration directly on the digital display, reads the CO2 set point and controls the percentage of CO2 in the incubator chamber. F. The IR controlled unit is known as a direct sensor and operates under the principal that a certain frequency of infrared light is absorbed by CO2. The more CO2 is present the more light is absorbed.
6 Section DATA LOGGER FUNCTION The data logger provides ways to externally indicate or log all the incubator front panel displays at intervals ranging from 1 to 99 minutes. The logger contains a real time clock/calendar to date and time stamp each logged reading. The logger indicates and logs all front panel display readings in single lines of text. This data is logged when the present logging interval has expired or one of the monitored displays has changed its alarm state.
7 Section FYRITE CO2 CHECKING A Bacharach FYRITE CO Gas Analyzer is recommended to measure CO concentrations in the incubator chamber. This test instrument is not supplied with the incubator but is readily available from your dealer. Follow the instructions provided with each Fyrite instrument carefully to insure correct and accurate readings. 7.1. Press button on top of Fyrite canister to release CO2 concentration. Tip canister to the side to ensure all fluid is released from top of canister. 7.2.
8 Section HEPA C02 FILTER The CO2 Incubator design features a HEPA filtration system with a patented copper housing. (Patent Number 6,333,004) As the chamber air is drawn through the filter system, airborne microbes and isolated particulates are not only removed from the air, but destroyed as well. It is through copper oxidation that the contaminants are actually killed. The HEPA filter is easily replaced without the need of any tools and has an efficiency rating of 99.97% at 0.3 microns.
9 Section MAINTENANCE NOTE: Prior to any maintenance or service on this unit, disconnect the service cord from the power supply. 9.1 Cleaning: Cleaning and decontamination are recommended on a regular basis. To prepare the incubator for cleaning remove all interior parts such as the shelf standards and false top. All stainless steel parts are autoclavable. Please review the Cleaning procedures described in the Installation section for detailed instructions. 9.
Section TROUBLESHOOTING 10 CAUTION: Extreme caution must be exercised any time access is made into areas housing electrical components. Repair, replacement or adjustment of components in these areas must only be done by qualified technicians familiar with electrical circuitry and the operation of the chamber. Always make a visual inspection of the incubator and control console when troubleshooting. Look for loose or disconnected wires or tubing, which may be the source of the trouble.
and see if heating light or safety light comes on 3/ check connections to sensor 4/ check calibration – using independent certified reference thermometer, follow instructions in sections 5.4 and 5.
CO2 LEVEL Overshoots set point but stabilizes display and Fyrite match 1/ turn set point up and down to see if solenoid valve works by feeling and listening to valve 2/ recalibrate with Fyrite, see section 5.11 and section 7.0 3/ fan not operating correctly a- fan motor stopped b- fan blade fell off c- wrong fan blade installed or mounted backwards 4/ wrong restrictor installed or missing altogether 5/ tank pressure too high, see section 5.9.
1/ calibration error - clear chamber for 12 hrs and confirm at "0" 2/ turn set point up and down to see if solenoid valve works by feeling and listening to valve 3/ assure that IR tube block is completely tight, 24 series 4/ if display is varying when doing Fyrite test, have a leak on IR base or mounting plate, or CO2 is injecting at time of test.
CO2 gas supply has been interrupted or run out. Tank ran out of gas or did not switch over. Pinched gas line tubing Severe leak in gas line Tubing is disconnected from the gas supply.
