Before the appliance is loaded with vaccines ensure that the temperature is below -15°C.
- Set the thermostat at position 5.
- Check the temperature on the thermometer.
- If the temperature in the vaccine compartment is above -15°C the thermostat should be adjusted. The temperature in the vaccine compartment must always be monitored on the thermometer and be within the range -15 to -25°C.
Due to the mechanical tolerance of the thermostats you should always control the temperature during cool down.
Temperature adjustment
This appliance is equipped with one thermostat. See Fig. 6 and Fig. 7.
Fig. 7
The thermostat is an electronic thermostat that controls the temperature in the vaccine and icepack freezing compartments. Setting 1 applies minimum cold and setting 8 maximum cold.
Loading the appliance
Loading vaccines
When the temperature in the freezer has stabilized, i.e. the temperature should be below -15 to -25°C and the compressor stops and starts, vaccines can be loaded. The vaccines should be placed in the mid part.
Loading and freezing of icepacks
The icepacks should be placed in the icepack compartment and the suspended tray. Make sure you have a good contact between the icepack and the evaporator surface. Fig. 8
Fig. 8
If thermostat is set to a warmer position, remember to check the temperature in the vaccine compartment.
Defrosting and cleaning
For the appliance to operate well and to save energy, it is important that it is cleaned and defrosted regularly.
When opening the appliance, moisture enters and settles on inner cold surfaces and forms a layer of frost or ice.
The layer of ice makes the freezer less efficient and must be removed, "defrosted".
It is recommended that the appliance be defrosted every third month.
Defrosting
The water-packs stored and the humidity of the air gradually causes frost and ice to form in the freezer compartment. A thin layer of frost or ice does not affect freezer performance, but a thick layer could cause the freezer not to cool water-packs satisfactory. Small amounts of loose frost can be removed using a plastic scraper.
Never use electrical apparatus or sharp implements as these may damage the inside of the appliance.
When the layer of frost and ice exceeds 4 - 5 mm the freezer should be completely defrosted.
Proceed as follows:
- Before defrosting, vaccines and/or water-packs must be moved to another working freezer or cold box with icepacks.
- Switch off the appliance.
- Open the drainage plug placed inside the freezer compartment.
- Place a tray under the defrost water drain.
- Place a bowl of hot (but not boiling) water in the freezer, close the lid and wait approx. 30 minutes before removing loose frost with the plastic scraper.
- To prevent water from damaging the floor during defrosting, it is advisable to check the defrost water tray from time to time and to cover the floor around the defrost water drain to protect against ice and splashes. When all the frost and ice have melted, clean the inside cabinet, as well lid, lid gasket, and outside of the cabinet using water with a mild, perfume-free detergent.
- Dry the freezer with a soft cloth, and make sure no moisture is remaining after cleaning.
- Reinsert the internal drainage plug, and check lid gasket is not faulty.
- Switch on the appliance, and make sure it is freezing (temperatures decreasing).
- Check that water-packs are not leaking before returning them to the freezer compartment. Store water-packs and vaccines according to instructions, approximately 5 minutes after having switched it on. Close the lid.
Cleaning
- Once the appliance is defrosted, it must be cleaned.
- Clean the inside of the appliance with a mixture of lukewarm water and a mild detergent.
- Allow the cleaned parts to dry completely.
- Clean the outside of the appliance with a mixture of lukewarm water and a mild detergent or soap. 5. Close the lid and follow the procedures in "Cool down of the appliance" on page 7.
Troubleshooting
| Fault Possible cause | Remedy | |
| Compressor is not running, and the ice packs are not cold | Be patient, it is most likely that the compressor will start within a few minutes. | If this is not the case, check the following: - Check that power is connected. - Check the fuse and replace it if necessary. - If the above is OK, call technical supervisor. |
| Compressor is running, and the temperature is too high | The ventilation grille is blocked. The lid is not closed properly. The temperature in the room in which the appliance is installed is too high. | Ensure unhindered air circulation. Ensure that the lid is closed properly. Shield the appliance against direct sun light and ensure more ventilation to the room. |
| No temperature is displayed | The thermometer is broken. There is not enough light for the solar sensor. | Change the thermometer. Turn on the light. |
