  • Page 9 Examples of troubleshooting with a manometer connected to the process piping of the cooling sy- stem. The system is blocked: Suction pressure is very low. Pressure equalization takes place very slowly or not at all. Reason: Icing or dirt in the capillary tube or ¿ lter, or blockings in the system due to other reasons. Reason: No compressor capacity The suction pressure is too high.
  • Page 10 3c. Opening of the cooling system To prevent moisture from penetrating under repair, the system must not be open for more than 15 minutes. Prepare spare parts components before the system is opened. The new connector is soldered to a tube with valve. Verify that the new filter packaging is intact and that the filter is not damaged.
  • Page 11 Process pipe and pressure tube fitted with a valve. The cooling system is evacuated with a two-stage vacuum pump for at least 30 minutes. Both from the pressure piping and process piping. Blow the system with nitrogen, both from the suction and the pressure side. 3e.
  • Page 12 Right Wrong In the figure A the capillary tube is correctly installed in a dryfilter. In order to ensure effcient use of the filter, it must be positioned with an inclination of at least 150 and the capillary tube must be underneath. In the figure B the capillary tube is too close too the web of the filter.
  • Page 13 3f. Changing the compressor Evacuate the refrigerant of the system. See section 3d. All tubes are cut with a pipe cutter. Do NOT solder of. When replacing the compressor the dryfilter must also be replaced. See section 3e. The suction and pressure pipes of the compressor must be cleaned and cut with a pipe cut- ter just above the soldering pipe.
  • Page 14 3h. Vacuum suction / Vacuum check A vacuum is made on two locations on the system, one on the process tube and one on the pipe branch used for testing located on the pressure tube with an explosion-proof 2-stage vacuum pump. The pressure should be 2 mBar or lower for at least 12 hours.
  • Page 15 Cylinder with manometer Vacuum suction of the filling hose Loading procedure Make vaccum. See section 3h. The cylinder with manometer is connected to the coupler of the process piping. Remember to first made vacuum in the filling hose to empty it. Fill the refrigerant into the system until the pressure gauge on the pressure tube shows approx.
  • Page 16 3j. Electrical troubleshooting Before starting systematic troubleshooting, check the following: Proper voltage is present. Electrical equipment used, is suitable for the compressor. The wires are properly installed according to wiring diagram. There is no transition between the live parts and ground. Control of the transition to ground.
  • Page 17 3k. Electrical fault - compressor Remove the start relay from the compressor and use an ohmmeter to test the compressor head and start recovery. Connect ohmmeter between the common connector and start winding, then the winding is to debug. See the picture below. Dimensions of the compressor connections to determine whether driving and startwinding are intact.
  • Page 18 3l. Controller - demounting the display Demounting of controlller Dixell XR30CX. The controller is located in the lower right corner on the front of the freezer in a cut-out 29 x 71 cm. Disconnect the power supply. Press the flaps on both sides of the controller. See illustration. Pull back the clips.
  • Page 19 A relay can be checked with an indicator light as shown in the sketch maintain end. The relay is usu- ally ok, when in standing position is not lit, and when it is lit when the relay is upside down. The start capacitor can be checked by injecting the normal voltage for a few seconds and than shorting it.
  • Page 20 3n. Sensor for the controller PT 100 A faulty sensor will typically prevent the compressor from starting. If the sensor is covered with ice, the compressor will run more than usual and cool too much. The easiest way to check the function of the sensor, is to place your hand around the sensor. If the temperature recorded on the display in the front panel does not rise, the sensor is faulty and needs to be replaced.
  • Page 21 3o. Condenser See section 4c. 3p. Fan If the ventilator stops, it can cause insufficient cooling of condenser and compressors. Electrically, the fan is connected to terminal 10 and 14 on the start relay. Physically, the fan is placed in the motor compartment close to the compressor and fixed on the panel with 2 bolts.
  • Page 22 4. Maintenance 4a. Rubber gasket of the lid Rub the gasket with a suitable product, so that it stays flexible and the optimal function and tight- ness is secured. Make sure the lid closes tightly so that no ice forms around the lid frame. Open the lid and place a piece of paper.
  • Page 23 4d. Evaporator The freezer, the lid frame and the sensor must be checked for ice. In case of large ice formation, the freezer must be defrosted. 4e. Manual defrost Remove the contents of the freezer. Unplug the unit. Place a tray under the freezer and remove the plug at the bottom of the freezer. Leave the lid open until the ice can be removed.
