Adjust thermostat setting if required, to main lain a
steady temperature between +4° to 8°C.
4) Preserve vaccine in the ILR, only after the above
recommended is attained in the ILR.
5. TO USE A FREEZER
DEFROSTING & CLEANING
The moisture in the air, which enters the ILR due to lid
opening (and also may be due to defective lid-gasket
or door alignment) is attracted by the cold surfaces
inside the ILR. So, formation of frost and ice occurs
on the walls around the tubes inside the lining
compartment. When the frost layer is 1 /4" to 1 /2"
(6-12 mm) thick, it is time for `defrosting' the ILR.
MOST IMPORTANT:
Before defrosting the ILR, the vaccines preserved
in it will have to be removed and stored temporarily
in other working ILR or Refrigerator.
If a second ILR or Refrigerator is not available, the
vaccines will have to be preserved in Cold-Box or
Vaccine carrier, properly lining the same with frozen
ice packs, such that the vaccine temperature
remains within the recommended storage
temperature during the defrosting of the ILR.
