    INSTALLATION EQUIRED MBIENT ONDITIONS The SRI chambers are intended for use indoors at room temperatures between 15°C and 30°C (59°F and 86°F), at no greater than an ambient 80% Relative Humidity (at 25°C / 77°F). Allow a minimum of 4 inches (100 mm) between the unit and walls or partitions, and 2.5 inches (60 mm) of clearance above the top of the chamber for unobstructed airflow.

  • Page 15: Power Source Requirements

    INSTALLATION OWER OURCE EQUIREMENTS When selecting a location for the unit, verify that each of the following requirements is satisfied. Power Source: The power source must match the voltage and ampere requirements listed on the unit data plate. These units are intended for 115 VAC 50/60 Hz applications at 9 amps. Supplied voltage must not vary more than 10% from the data plate rating.

    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 dunnage from the shelving.

  • Page 18: Deionized And Distilled Water

    INSTALLATION EIONIZED AND ISTILLED ATER Do not use deionized water to clean the chamber. 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 38: Load The Chamber

    OPERATION OAD THE HAMBER The manufacturer strongly recommends waiting at least 8 hours after placing the chamber in operation before loading samples in the chamber. This safeguards samples against temperature instability. The samples should by placed at least 1 inch (25 mm) away from the chamber walls. Good spacing allows for maximum air circulation and a higher degree of temperature uniformity.

  • Page 43: 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 44 USER MAINTENANCE Factors in Ice Build Up Incubators and diurnal chambers 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 45 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.

Bookmark not defined. for device requirements. Temperature calibrations are performed to match the chamber temperature display to the actual air temperature in the incubation chamber.
  • Page 47 USER MAINTENANCE Temperature Stabilization The chamber air temperature must stabilize in order to perform an accurate calibration. Additionally, the unit must be calibrated twice — once at your application day temperature and then at your application night temperature to compensate for the extra heat generated during the day mode by the day illumination bulbs in the chamber.
