7 Maintenance and repair
WARNING
• Before cleaning or carrying out maintenance work, always switch the machine off and disconnect the
mains plug. Working on the connected appliance may cause electric shock or fire.
• When disconnecting, always pull the plug and never the cable. Pulling the cord may result in electric
shock or fire due to a short circuit.
• During defrosting, water will leak from the unit. Collect this water so that it does not lead to a risk of
slipping for passing persons.
• Watch out that no water can penetrate the ventilation slots of the unit.
• Before cleaning or carrying out maintenance work, the contents preserved in it will have to be removed
and stored temporarily in another working refrigerator.
• Make sure the condensation water is removed on a weekly basis. Increased condensation water inside
the device may lead to malfunctioning of the device.
• Inspect the unit on a regular basis for damaged parts. Only genuine spare parts may be used. Use of
any other parts may affect the performance or cause physical injury or damage to the equipment.
CAUTION
• The use of hydrogen peroxide H2O2 (VHP) for the disinfection (sterilization) of the appliances is not
suitable. This procedure may be applied exclusively with dedicated appliances.
• Other than the cleaning procedure described in this manual, follow the internal policy and procedures.
• Before using the refrigerator it should be cleaned inside and outside.
• For cleaning, use only gentle cleaning agents. Never use aggressive or caustic cleaning agents, scouring
powder, steel wool, abrasive sponges or chemical solvents. When cleaning, make sure that no fluids of
any kind run into the ventilation housing.
• For disinfecting, we recommend all the surface disinfecting agents commonly used by the customer,
provided they are recommended by the national organizations. For disinfecting small areas, we
recommend using a concentrated alcoholic agent.
7.1 Cleaning
• Switch off the MRB3000SDD and disconnect it from power supply.
• Prepare the temporary storage and transfer the stored goods and preserve them properly with care.
• Clean all parts inside and outside the cabinet, the lid and the lid gaskets with warm water and mild
detergent. Allow the cleaned parts to dry completely.
• Close the lid. Connect the power supply and switch on the MRB3000SDD.
• Allow it to run and observe the cabinet temperature on the display.
• Put back the blood bags into the MRB3000SDD from the temporary storage, only when it has attained
safe recom mended temperature range for storage.
7.2 Condensation water
• The moisture in the air, which enters the cabinet
due to lid opening is attracted by the cold surfaces
inside. The moisture will condensate on these cold
surfaces. The condensation water is collected at the
bottom of the inner cabinet and must be evacuated
on a regular basis (at least once a week) using the
drainage plug on the front side of the cabinet.
• Open the drainage plug at the bottom front side
the cabinet. Keep a suitable container under the
drain hose to collect the water.
• Close the drainage plug after all water is evacuated.
