3. HOW TO USE
7.
If the cabinet temperature does not reach the required
low level of 2-3 days, the freezer-thermostat setting
can be increased to a higher setting by turning its
knob clockwise.
8.
After storing the vaccines, keep the lid properly closed
and locked (fig. 13).
DEFROSTING & CLEANING
The moisture in the air, which enters the appliance
due to lid opening (and also may be due to defective
lid-gasket or door alignment) is attracted by the cold
surfaces inside the appliance. So, formation of frost
and ice occurs on the walls. When the frost layer is 1
/4" to 1 /2" (6-12 mm) thick, it is time for `defrosting'
the appliance.
MOST IMPORTANT:
Before defrosting the appliance, the vaccines
preserved in it will have to be removed and stored
temporarily in other working freezer.
If a second appliance 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 appliance.
DEFROSTING & CLEANING
PROCEDURE
1.
Switch OFF the power supply to the appliance and
remove the plug of its power supply cord from the wall
socket.
2.
Prepare the temporary storage and transfer the
vaccines and preserve them properly with care.
