Defrosting
A manual defrosting procedure should be performed periodically on the fridge
compartment of the appliance to maintain its operating efficiency. Over time, as the
door is opened and closed, letting in new air, water vapor from the air condenses on
the cooling elements within the cabinet.
Transportation / Transport
The unit can be transported and stored (when the product is inactivated) in ambient
temperatures ranging from -30°C to +55°C and can be transported, stored and used
(activated) in relative humidity from 5% to 95%.
Diagnosing a problem
1. If the temperature indication on the freezer compartment goes below -20°C
then call a maintenance engineer to look at the thermostat control.
If the temperature is above -10°C then:
2. Check the door is closed and sealing properly
– If seals are damaged then
report this and get the seals changed.
3. Use something of known temperature to assess the calibration of the
thermometer. Also check the compartment temperature with a portable
thermometer e.g. glass/alcohol type.
4. Check the mains supply.
5. Check if the unit has been receiving electricity within the allowed tolerance of
voltage output supply in your country.
6. Check connection to the mains.
If 3,4,5 & 6 all appear to be in order then remove the vaccines to a safe location
and, ensuring constant supply of electricity, monitor the
freezer’s progress over a
1 week period.
