MF-Model is a vaccine storage freezer and
icepack freezer. It has two compartments;
one for vaccine storage and one for icepack
freezing.
Power supply
The MF vaccine freezer is equipped with
a heavy-duty compressor that can operate
at voltages 22% below nominal voltage.
See the rating plate. If voltage variations go
beyond this range it is recommended to use
an automatic voltage stabilizer.
Unpacking
1. Unpack the appliance and check that it
has not been damaged. If you observe
any damage, inform your supervisor.
2. Check the rating for correct voltage and
frequency.
3. Open and remove all internal packing
material.
Unpacking and installa-
tion
Installation
The appliance must be placed in a well ven-
tilated room, not in direct sunlight and away
from other heating sources.

Instructions to User:
Every refrigeration unit must be connected
to an individual stabilizer.
Bypassing of Stabilizer is not recommend-
ed, as such practice may lead to damage
of the CCE & in turn safety of vaccines &
hence must be avoided.
Proper earthing should be available and
connected.
Emphasize on repairing stabilizers immedi-
ately. Identify authorized Vestfrost service

Cool down of the appliance
Before the appliance is loaded with vac-
cines ensure that the temperature is below
-15 °C:
Set the thermostat at position 5
Check the temperature on the thermo-
meter
If the temperature in the vaccine com-
partment 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 -20°C.
Due to the mechanical tolerance of the
thermostats you should always control the
temperature during cool down .
This appliance is equipped with one
thermostat. See Fig. 6 and Fig. 7

Thermostat
The thermostat is a 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 -20°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
Fig. 8
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-

It is recommended that the appliance be
defrosted every third month.
If thermostat is set to a warmer position,
remember to check the temperature in
the vaccine compartment
Defrosting
The water-packs stored and the humidity
of the air gradually causes frost and ice
to form in the freezer compartment. A thin

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.
