insulating material. This will keep the coldness of the icepacks during defrosting of the unit.
• To speed up the defrosting process, gently remove the complete inner liner by holding it on its two oppo-
site sides and lifting it uniformly.
• Open the drainage plug at the bottom front side the cabinet. Keep a suitable container under the drain
hose to collect the defrost water.
• Keep the lid open and allow the frost to melt completely. Never use any heat source other than hot water
to speed up defrosting or any sharp-edged instrument for removing frost.
• Clean all parts inside and outside the cabinet, the lid and the lid gaskets with warm water and mild deter-
gent. Allow the cleaned parts to dry completely.
• Reset the drainage plug at its position at the bottom.
• Put back carefully the inner liner into its position.
• Take the ice pack holders one by one, wipe their outside with a clean dry cloth and put them back care-
fully into their positions. Examine the icepacks for any leakage of water from any portion, before putting
them back to the MB3000G. A defective icepack will have to be replaced.
• Replace the cabinet frame.
• Close the lid. Connect the power supply plug to the wall socket and switch on the MB3000G.
• Allow it to run and observe the cabinet temperature.
• Put back the contents into the MB3000G from the temporary storage, only when it has attained safe rec-
om mended temperature range for storage.
8.3 Periodic Maintenance
• Examine the icepack compartment and check frost formation. If necessary defrost as described earlier.
• If it is observed that defrosting is required to be done each week:
• Examine the gaskets on the lid, if they sit properly. Any gap between the cabinet and gaskets will
allowoutside air to go in and form frost early. In such cases the hinges should be adjusted or the
gaskets should be changed.
• Restrict and reduce frequency of opening the MB3000G. Open only when absolutely necessary.
• Clean the compressor compartment regularly using a hand brush or a vacuum cleaner. The cleaning inter-
val is specified at the factory and is indicated by the appearance of the CLEAN message on the display :
• Switch off the unit and unplug it from the wall socket.
• Take out the side-cover of the compressor compartment. Clean the interior of the compressor com-
partment as well as the condenser on the back side of the unit with a soft brush or a vacuum cle-
aner.
• Fit back the side cover.
• Clean the lid seal.
