INSTALLATION NSTALLATION HECKLIST For installing the unit in a new workspace location. Pre-Installation Check that the required ambient conditions and ventilation spacing for the incubator are met, page 14. Unit dimensions may be found on page 39. • Check that a suitable electrical outlet and power supply is present, page 15. -
Page 14: Required Ambient Conditions
INSTALLATION EQUIRED MBIENT ONDITIONS When selecting a location to install the unit, consider all environmental conditions that can adversely impact its temperature performance. These include: Proximity to ovens, autoclaves, and any device that produces significant radiant heat • Heating and cooling vents or other sources of fast-moving air currents •... -
Page 15: Power Source Requirements
The power source for the unit must match the voltage and the amperage requirements listed on the unit data plate. These units are intended for 110 - 120V 50/60 Hz (SRI3) or 220 – 240V 50/60 Hz (SRI3-2) applications at the following amperages:... -
Page 16: Lifting And Handling
INSTALLATION IFTING AND ANDLING 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. •... -
Page 17: Adjust Shelves
INSTALLATION DJUST HELVES Note: The form factor of the shelves may vary slightly by year of production. The unit ships with its shelves installed in the incubation chamber. Tape, foam, and other packing dunnage is used to secure the shelves during transit and prevent damage to the chamber interior. Remove all shipping materials from the shelving. -
Page 18: Deionized And Distilled Water
INSTALLATION EIONIZED AND ISTILLED ATER Do not use deionized water to clean the chamber even if it is readily available in your laboratory environment. Use of deionized water may corrode metal surfaces and voids the warranty. Sheldon Manufacturing 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 applications. -

Page 23: Operation
OPERATION HEORY OF PERATION Refrigerated incubators are engineered to provide constant temperature incubation environments suitable for BOD applications. The unit can obtain a stable, uniform temperature in its chamber, ranging from 0°C up to 40°C. Achieving and Maintaining the Temperature Set Point When the unit is powered, its refrigeration compressor runs continuously. -
Page 24: Put The Incubator Into Operation
OPERATION UT THE NCUBATOR INTO PERATION Putting the incubator into operation in a new workspace environment requires an 8-hour period for the unit to come up to and stabilize at temperature prior to loading the incubation chamber with samples. During this period the incubator must be powered with the chamber door closed. Allowing time for stabilization helps protect samples. -
Page 25: Set The Temperature Set Point
OPERATION ET THE EMPERATURE OINT The incubator comes from the factory with a set point of 20°C. Perform the steps below to change the set point to your process or application temperature. Set Temperature Set Point Turn the OTL dial clockwise to its max setting, if not already set at max. -
Page 26: Set The Over Temperature Limit
OPERATION Note: Test the OTL system at least once per year for functionality. ET THE EMPERATURE IMIT The incubator must be operating at your incubation application temperature and must be stable for at least 1 hour prior to setting the OTL. Allow the unit to operate for at least 8 hours prior to setting the OTL when first placing it into operation. -
Page 27: Loading Samples
UTLET Outlets The SRI3 is provided with 2 power outlets inside the chamber. Do not attach powered equipment drawing more than 1 amp from both outlets. The SRI3-2 is provided with 1 power outlet inside the chamber. Do not attach powered equipment drawing more than 1 amp from the outlet. -
Page 28: Condensation And The Dew Point
OPERATION ONDENSATION AND THE OINT Relative humidity inside the incubation chamber should never be allowed to exceed 80% at 25°C. Exceeding this threshold will likely result in condensation, possible leaks around the incubator, and may cause corrosion damage if allowed to continue for any significant length of time. Condensation takes place whenever the humidity level in the incubation chamber reaches the dew point. -
Page 29: User Maintenance
USER MAINTENANCE Warning: Disconnect the unit from its power supply prior to performing maintenance or services. Avertissement: Débranchez cet appareil de son alimentation électrique avant d'effectuer la maintenance ou les services. LEANING AND ISINFECTING If a hazardous material or substance has spilled in the unit chamber, immediately initiate your site Hazardous Material Spill Containment protocol. -
Page 30: Minimizing Contamination Exposure
USER MAINTENANCE Disinfecting For maximum effectiveness, disinfection procedures are typically performed after cleaning. Keep the following points in mind when disinfecting the unit. Turn off and disconnect the unit to safeguard against electrical hazards. • Disinfect the unit chamber using commercially available disinfectants that are non-corrosive, •... -
Page 31: Refrigeration And Defrosting
USER MAINTENANCE EFRIGERATION AND EFROSTING The refrigeration compressors of most home refrigerators run periodically in order to maintain an average chamber temperature centered on the thermostat setting. This results in temperature oscillations of up to 2° or 3°C and reflects the fact that affordable refrigeration compressors cannot provide the high degree of temperature stability needed for laboratory applications —... - Page 32 USER MAINTENANCE Factors in Ice Build Up Incubators used for biologic oxygen demand studies and other closed-container applications will generally require infrequent and very short defrost runtimes. However, runtimes may be prolonged and occur more frequently if the incubator is used in a high humidity environment with the door opened several times a day or left open for prolonged periods.
- Page 33 USER MAINTENANCE Turning Off the Automatic Defrost Deactivating the defrost thermostat will result in ice accumulation and a gradual loss of cooling efficiency. Incubators used for BOD and other closed-container applications with the defrost thermostat turned off will likely require manual defrosting every 6 months. Units with open sources of water evaporation and the defrost thermostat shut off will require manual defrosting every 2 to 3 months.

Page 34: Calibrate The Temperature Display
USER MAINTENANCE ALIBRATE THE EMPERATURE DISPLAY Note: Performing a temperature display calibration requires a temperature reference device. Please see the Reference Sensor Devices entry on page 7 for device requirements. Temperature calibrations are performed to match the incubator temperature display to the actual air temperature in the incubation chamber. - Page 35 USER MAINTENANCE 5. Temperature Stabilization The incubator air temperature must stabilize in order to perform an accurate calibration. Allow the incubator to operate undisturbed with the door shut for at least 8 hours when first • putting the unit into operation in a new environment. To be considered stabilized, the incubator chamber must operate at your calibration •...
- Page 36 USER MAINTENANCE Temperature Calibration Continued Place the display in temperature calibration mode. a. Press and hold both the UP and DOWN temperature buttons simultaneously for approximately 5 seconds. b. Release the buttons when the temperature display shows the letters “C O”. The display will begin flashing the current temperature display value.
- Page 37 USER MAINTENANCE Temperature Calibration Continued Reference Device Compare the reference device reading with the chamber temperature display again. If the reference device and the chamber temperature display • readings are the same or the difference falls within the range of your protocol, the incubator is now calibrated for temperature.
