1. Controller was calibrated at the factory at 37 C however it is recommended that calibration is done once the unit is installed in its working environment and has been stable at set point for several hours Place a certified reference thermometer in the chamber Be certain the thermometer is not touching any shelving Allow the temperature to stabilize again until the thermometer reads a constant value for one hour Compare the digital display with the reference thermometer If there is an unacceptable difference put the display into calibration mode by pressing both the Up and Down arrow pads at the same time until the two outside decimal points begin to flash While the decimal points are flashing the display can be calibrated by pressing the Up or Down arrow pads until the display reads the correct value Allow the incubator temperature to stabilize again and recalibrate if necessary Set Safety Thermostat As mentioned in step 7 3 the Safety Thermostat should be initially set to its maximum position to allow the unit to stabilize Once the incubator is stabile at the desired set point turn the Safety Thermostat counterclockwise until the Safety Light turns on Next turn the Thermostat clockwise just until the Safety Light turns off Then turn the Thermostat clockwise two 2 of its smallest divisions on its scale past the point where the Safety Light went out This will set the Safety Thermostat at approximately 1 C above main temperature se2. of purchase This guarantee is valid only if the unit has been used in accordance with the instructions in this manual and for its intended purpose Labnet International Inc shall not be responsible for consequential damages or damages resulting from the abuse or misuse of this equipment Labnet International s liability shall be limited to the repair or replacement of the unit or refund of the purchase price at Labnet International s discretion For technical service contact Labnet International s Service Department at 888 522 6381 Labnet International Inc reserves the right to alter the specification of the incubator without notice This allows the incorporation of improvements as they are developed Please fill in the following information This information will be required in the event that service becomes necessary The serial number is found on the data plate located on the back of the unit Serial number Date of purchase Section SPECIFICATIONS Temperature Uniformity 0 2 37 C 0 25 37 C solid heated Chamber Volume 22 Exterior Dimensions Interior Dimensions 21W x 20D x 25 H Standard Accessories Adjustable leveling feet 2 Steel Shelves Shelving Points Power Curent J Door Section RECEIVING AND INSPECTION 4 1 4 2 4 3 4 4 Inspection The carrier when accepting shipment also accepts responsibility for safe delivery and is liable f
