Install the rotator The rotator (also called rotisserie, Sheldon part number 9670511; see Figure 5) comes with your 1013 oven. To install the rotator into the oven: 1. Set the AC power switch to OFF. 2. Open the oven. Locate the rotator drive shaft coupling on the left side oven wall and the rotator shaft support bushing on the right side oven wall. See Figure 2. 3. Move the rotator into the oven and insert the two pins on the rotator drive shaft coupling into the two holes on the rotator coupling.
3 Section Operation Control Panel Interface The 1013 Hybridization Oven is operated using the control panel interface (see Figure 6), which is located on the front of the oven. Rotational speed control Use to set the rotator speed from 2 to 20 rpm. Turning the knob clockwise increases the rotator speed. Set to 0 (zero) to turn off the rotator. Heating indicator Lights continuously when the oven is heating. Blinks when the oven is at or near its set point.
Operating the Hybridization Oven To set a temperature Using the temperature controller: 1. Enter set point mode by pressing either or The digital display will start to blink. While blinking, the digital display shows the current set point. 2. Press or to enter the desired set point temperature. If the arrow pads are not pressed for five (5) seconds, the display will stop blinking and will read the temperature in the chamber.
To calibrate the oven Calibrate the oven: • After first installation in a working environment. • After each 3 months of use To calibrate the oven: 1. Install the rotator and load it with a typical number of chambers. 2. Turn on the oven and set to a typical operating temperature. 3. Allow the oven to stabilize for at least 1 hour. 4. Place a certified reference thermometer in the chamber near the sample area. 5.
4 Section Maintenance and Troubleshooting Cleaning To clean the unit: 1. Remove the rotator and drip tray. 2. Clean the oven using mild detergent. 3. Clean the rotator and drip tray using either the same solution used for the chamber, or an autoclave. Storage If the unit is to be turned off for any length of time, assure that the chamber and drip tray are dry and store at room temperature. Failure to do this may cause the interior to become contaminated.
Replacing the inline power fuse The unit is protected by an inline fuse located behind the power cord. If needed, replace the fuse as described below: 1. Turn off the oven and rotator, then disconnect from the power source. 2. Remove the power cord from the back of the oven. 3. Using a small, flat-bladed screwdriver pry the fuse holder from the back of the unit. See Figure 8. 4. Inspect the fuse in service. See Figure 9. Replace if blown with a 6.3 A, 250 V type T fuse.
Troubleshooting The following table shows a list of problems and their corresponding solutions. If these instructions do not correct the problem, call Customer Service for further assistance. Table 1 Problems and solutions Problem Action The unit will not turn on. 1 Verify that the power cord is plugged into the oven and power source. 2 Verify that the power switch is ON. 3 Check the fuse as described in “Replacing the inline power fuse” on page 15 and replace if blown.
Table 1 Problems and solutions (continued) Problem Action The indicated chamber temperature is unstable. Temperature range ±1 °C is normal. 1 Check to make sure the fan is working by checking the fan motor motion and feeling for air movement in the chamber. Verify movement of the cooling fan in the back of chamber. 2 Doors opening, air flow from heaters, and air flow from air conditioner units may radically change the ambient room temperature. Stabilize ambient conditions.
