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 evaporater
surface. 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 en-
ters and settles on inner cold surfaces and
forms a layer of frost or ice.
The layer of ice makes the freezer less ef-
ficient 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 satisfac-
tory. Small amounts of loose frost can be
removed using a plastic scraper.
Never use electrical apparatus or sharp im-
plements 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:
Fig. 8
1. Before defrosting, vaccines and/or
water-packs must be moved to another
working freezer or cold box with ice-
packs.
2. Switch off the appliance.
3. Open the drainage plug placed inside the
freezer compartment.
4. Place a tray under the defrost water
drain.
