Instructions for use
REFRIGERATOR USE
• Install and prepare the TCW3000DC as detailed under “Installation” and “Preparation”. Ensure that the icelining panels are correctly introduced before starting the TCW3000DC in refrigerator mode.
• Shift the ON/OFF-switch to position “I”. The temperature display lights up to show that the unit is ready for operation.
• After switching on, the compressor only starts after a deceleration time of 3 minutes. This also applies, if the equipment is switched off and on again.
• Close the lid and allow the unit to run. The temperature inside the cabinet is indicated on the display. Observe the temperature from time to time.
• Initially the temperature inside the TCW3000DC will be observed to be similar to or slightly below the room temperature. It will decrease slowly and remain steady within a small range after a day or two.
• When the temperature inside is observed to be steady for several hours within the required range, only then the vaccines to be preserved should be transferred to the TCW3000DC.
• The vaccines which get damaged if frozen, are advised to be kept in the baskets provided.
• After storing the vaccines keep the lid properly closed and locked.
• When fresh vaccines are stored in the TCW3000DC, the cabinet temperature may go up initially but should fall and come to the required range after few hour
The cabinet temperature may vary depending upon various factors, such as,
• the ambient temperature
• amount of vaccine preserved in the TCW3000DC
• frequency of lid opening
• circulation of air around the TCW3000DC
Precautions for Use
SAFETY
• The unit must only be used by adults. This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety. Children should be supervised to ensure that they do not play with the appliance.
• All installation work and adjustments to the unit must only be carried out by qualified personal. Work performed by persons with insufficient technical knowledge may adversely affect the performance of the unit or cause physical injury or damage to the equipment.
• All servicing and repairs must only be carried out by a qualified customer service engineer. Only genuine spare parts must be used.
• Ensure that the connecting cable is not squeezed or bent when the unit is being installed or moved.
• Before cleaning or carrying out maintenance work, always switch the unit off and disconnect from power supply. If the plug is not accessible, switch off at the circuit fuse.
• The unit's cooling system contains refrigerant. Both the unit and the products stored inside can be severely damaged if this system starts to leak. Make sure, therefore, that no sharp or pointed objects come into contact with the cooling system.
ENVIRONMENTAL PROTECTION
• Make your contribution to saving the environment. Bear in mind that orderly and proper disposal is required. Packaging materials and devices are always recyclable and should be taken for recycling.
• Before scrapping an old unit, remove the lid so that children cannot lock themselves inside while playing.
• When disposing of the unit, make sure that it does not get too hot, as combustible gas would cause the insulating foam to froth up.
Maintenance
PERIODIC MAINTENANCE
Daily
• Take temperature readings and note down the temperature and the time of reading. Keep the temperature records systematically. It is suggested that minimum 2 readings should be taken (in the morning and afternoon) preferably at the same hours of each day.
Weekly
• Examine the water pack 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 allow outside 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 TCW3000DC. Open only when absolutely necessary.
Monthly
• Clean the unit from any dust :
• Switch off the TCW3000DC and disconnect it from power supply.
• Clean the condenser on the back side of the unit with a soft brush or a vacuum cleaner.
• Clean the lid seal.
• If possible, put a standard mercury thermometer inside the cabinet and compare the readings with those of the dial thermometers and see if they are correct. Dial thermometers with incorrect readings have to be replaced, as incorrect readings may lead to wrong storage temperature and loss of the potency of the vaccines preserved.
