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 are 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 user item. 2.2 Indicates "Temperature". 2.3 Indicates "Overtemperature Safety". 2.4 C 2.5 CO Indicates "Degrees Centigrade". 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%.
A. B. C. D. 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. 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.
3.6 Shelves and Interior Parts: Shelving, clips and a humidity pan are supplied with each unit. See Figure 1 for proper placement of these accessories. Also see similar shelf assembly instructions sent with the accessory kit. 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.
4 Section CONTROL PANEL OVERVIEW 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.
measure the CO content in the chamber at this port.
5 Section OPERATION READ THIS SECTION ENTIRELY BEFORE ATTEMPTING OPERATION IMPORTANT: In order to assure the proper operation of this incubator, it is essential that you regularly verify the accuracy of the temperature and CO controls. Temperature can be confirmed by use of a thermometer inside of the chamber. CO 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.
To mute the audible alarm on either the Temperature or the CO2 Controls, push one of the up or down arrows and hold it down until the yellow led light illuminates and the audible alarm silences. While the incubator is warming, the low alarm will activate within 15 minutes. To set the CO2 Control Set Point, push one of up or down arrows once on the CO2 Display. The display should start blinking “SP”. While blinking push the Up/Down arrow to move the Set Point up or down to the desired set point.
D. 5.9 After the Main Temperatures are set and adjusted, the Overtemperature Safety Control needs to be set. Do this by turning the OTP Control Knob counterclockwise until the Overtemperature Light comes on (this will blink in sequence with Heating Activated Light). Next, slowly turn the knob clockwise until the light goes off, then turn the knob another 8 degrees approximately. This should set the Overtemperature 1 degree above the Main Temperature set point.
Do not use single stage regulators. A two gauge regulator is not necessarily a dual stage regulator. Insure that you are using a dual stage regulator. C. It is normal for the high pressure gauge on your regulator to start out reading 800 to 1000 PSI with a full tank. This reading will drop to 500 to 800 PSI quickly and will stay there for most of the duration of the tank. At the end of use, the pressure will drop quickly to zero, indicating that the tank is completely empty.
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 MAINTENANCE NOTE: Prior to any maintenance or service on this unit, disconnect the service cord from the power supply. 7.1 Cleaning: Cleaning and decontamination are recommended on a regular basis. To prepare the incubator for cleaning remove all parts such as the shelves, shelf standards and false ceiling. If it becomes necessary to pull out the Lab Stopper on the side of the unit (Part Number 102095), clean and reinstall the stopper from inside the chamber.
8 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. Look for loose or disconnected wires or tubing, which may be the source of the trouble.
Unit will not heat over a temperature that is below set point 1/ confirm that fan motor is moving and that amperage and voltage match data plate – check fan motor motion in shadow box and feel for air movement in chamber 2/ confirm that set point is set high enough ,turn OTP counterclockwise 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.
Display and reference thermometer don’t match 1/ calibration error – see section 5.
Never rises 1/ 2/ 3/ 4/ 5/ 6/ 7/ CO2 tank empty solenoid failed while closed CO2 controller output failed while open restrictor plugged CO2 hose blockage CO2 filter plugged set point is at 0.
Feeding continuously or abnormally high CO2 usage 1/ do decay test: if more than 1% decay in an hour, check for leak : door gasket tightness, motor inlet to chamber, sensor and probe inlet to chamber 2/ check output signal from controller 3/ check solenoid valve for correct operation 4/ leak in plumbing including between regulator and CO2 tank 5/ door being opened too often Won’t hold calibration – Fyrite reading varies but display stable 1/ 2/ 3/ 4/ 5/ 6/ 7/ 8/ atmospheric pressure fluctuations top of uni
3/ see what other loads are on the wall circuit Unit will not turn on 1/ 2/ 3/ 4/ check wall power source check fuse/circuit breaker on unit or in wall see if unit is on, e.g., fan or heater, and just controller is off check all wiring connections, esp. around the on/off switch Unit is smoking – Out of box Put unit under vent and run at full power for one hour.
