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%.
B. 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. DO NOT USE hard tools such as metal wire brushes or steel wool. Use non-abrasive cleaners and soft tools such as plastic brushes. TYPICAL DECONTAMINATION PROCEDURE 1. 2. 3. 4. 5. 6. 7. Remove the humidity pan every week and autoclave, or wash with soap and water then disinfect with 70% alcohol solution.
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. Figure 1 3.7 Download USB Software: Go to www.shellab.com website home page and scroll down towards the bottom of the page. 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. Open the Excel Spreadsheet SLDL0092 and download information.
4 Section CONTROL PANEL OVERVIEW (See Figure 2) 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.
4.9 Interface Ports: Located on the front left of the control panel opposite the Over Temperature Safety, these three (3) ports are where the logged data can be externally accessed through serial and parallel functions. 4.10 CO2 Sample Port: This is located on the front left side of control panel. A sample can be drawn to measure the CO2 content in the chamber at this port.
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 CO 2 control system, the water jacket must be filled and the temperatures adjusted as noted in section 5.7. Figure 3 A. The CO2 inlet fitting is located at the back of the unit near the top (see Figure 3). It is marked CO2 TO CHAMBER.
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. Its accuracy is consistent no matter what the conditions are in the incubator.
6 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 the Fyrite instrument carefully to insure correct and accurate readings. 6.1 Press button on top of Fyrite canister to release CO concentration. Tip canister to the side to ensure all fluid is released from the top of canister. 6.
7 Section HEPA CO2 FILTER The CO2 Incubator design features a HEPA filtration system with a patented copper housing. (Patent No. 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.
8 Section MAINTENANCE NOTE: Prior to any maintenance or service on this unit, disconnect the service cord from the power supply. 8.1 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. 8.
9 Section TROUBLESHOOTING 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. disconnected wires or tubing, which may be the source of the trouble.
1/ verify that controller is asking for heat by looking for controller light – if pilot light is not on continuously during initial start up there is a problem with the controller 2/ check amperage – amperage should be virtually at maximum rated (data plate) amperage 3/ do all controller functions work? 4/ is the OTP set high enough? – for diagnostics, should be fully clockwise with the pilot light never on 5/ has the fuse/circuit breaker blown? Indicated chamber temperature unstable 1/ ±0.
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.A 6/ CO2 sensor partially plugged with dirt or condensation 7/ regulator set wrong, see section 5.

1/ if shaft spins freely: check connections to motor and check voltage to motor; 2/ if shaft rubs or is frozen, relieve binding and retest Motor makes noise 1) Make sure that the fan or blower wheel is not contacting its housing. Adjust the motor mounting bracket position to re-center the fan or blower wheel, if necessary. 2) Check the fan or blower wheel for damage or out of balance condition. Replace the fan or blower wheel if it is damaged or out of balance.
