Operation and function
Electronic thermostat
The appliance has an electronic thermostat
that controls the temperature in the vaccine
compartment. The thermostat is set by the
factory

indicate that the appliance is operating. The
electronic thermostat makes a self test, 20
seconds before the compressor starts.
Temperature control
It is recommended to check the inside
temperature with an accurate thermometer
once a day. The inside temperature must
be checked regularly according to WHO’s

Cool down of the appliance
Before the appliance is loaded with
vaccines the ice-lining in the 4 sides must
be frozen. To ensure that the ice-lining in
the 4 sides is frozen do the following:
1. Place a thermometer in the top basket.
2. Plug in the appliance, and let it run for
24 h.
3. Check the temperature in the top and
bottom basket (must be between +2° and
+8°C).
The temperature in the vaccine
compartment must always be monitored
on the thermometer and be within the
range +2° to +8°C. Due to tolerance of the
thermostat you should always control the
temperature during cool down.

Loading the appliance
Loading vaccines
When the temperature in the vaccine
compartment has stabilized, i.e. and the
temperature is between +2° and +8°C and
the compressor stops and starts, vaccines
can be loaded. The vaccines should be
placed and arranged in the baskets, and

To ensure air-circulation and prevent too
low vaccine temperature, direct contact
to the inside walls must be avoided. The
Vaccine load in the bottom basket shall not
be higher than 250 mm.

Daily maintenance:
The temperature in the vaccine
compartment must always be monitored
on the thermometer every day. Please note
that the vaccine in the appliance may not
freeze.
Weekly maintenance:
During normal use, water can accumulate
at the bottom of the appliance; remove with
a cloth or through the drainage hole.
Wipe of water droplets on the inside wall at
the same time.
Under certain ambient conditions, rime can
form on the inside wall. Remove the rime
without using sharp edged tools.
Check if lid gasket is sealing tight to the top
frame when the lid is closed. A tight sealing
lid reduces accumulation of water and for-

Monthly maintenance:
Clean the grill on the right side of the
refrigerator once each month.
Yearly maintenance:
Electric connections and components are
to be checked and cleaned once a year or
more if necessary.
Maintenance and cleaning
Cleaning
Disconnect the power supply before
cleaning. The best way to clean the
appliance is by using luke warm water with
a small amount of unscented detergent.
Never use cleaning agents that scour. Use
a soft cloth. Rinse with clean water and dry
thoroughly. It is important to prevent water
from running into the control panel.
The sealing strip around the lid must be
cleaned regularly to prevent discolouration
and prolong service life. Use clean water.
After cleaning the sealing strip, check that it
continues to provide a tight seal.
If the appliance is not being used for any
period of time, switch off the appliance,
disconnect the power supply, empty the
appliance, clean the inside, and leave the
lid open to allow air circulation and prevent
smells.

Trouble shooting
Fault Possible cause Remedy
Compressor is not run-
ning, and the ice packs
are not cold
Be patient, it is most likely that the
compressor will start within a few
minutes.
If this is not the case, check the fol-
lowing:
- Check that power is connected.
- Check the fuse and replace it if
necessary.
- If the above is OK, call technical
supervisor.
Compressor is running,
and the temperature is
too high
The ventilation grille is blocked.
The lid is not closed properly.
The temperature in the room in which
the appliance is installed is too high.
Ensure unhindered air circulation.
Ensure that the lid is closed properly.
Shield the appliance against direct
sun light and ensure more ventilation
to the room.
No temperature is
displayed
The thermometer is broken.
There is not enough light for the solar
sensor.
Change the thermometer.
Turn on the light.

L’appareil est muni d’un thermostat
électronique pour le contrôle de la
température dans le compartiment à
vaccins. Le thermostat est réglé au départ
d’usine.

l’appareil est connecté à l’alimentation
électrique.
2. Thermomètre.

(Fig. 4) pour indiquer que l’appareil est
en fonction. Le thermostat électronique
procède à son propre test, 20 secondes
avant la mise en route du compresseur.

température intérieure doit être contrôlée
régulièrement.
Refroidissement de l’appareil
Avant que les vaccins soient chargés dans
l’appareil, la contre-paroi réfrigérante sur
les 4 côtés doit être gelée. Pour s’assurer
que la contre-paroi réfrigérante sur les 4
côtés est bien gelée, procéder comme suit :
1. Placer un thermomètre dans le panier
supérieur.
2. Branchez l’appareil et laissez-le
fonctionner pendant 24 h.
3. Contrôler la température dans les paniers
du haut et du bas (celle-ci doit se situer
entre +2 et +8 °C).
La température dans le compartiment à
vaccins doit être constamment contrôlée sur
le thermomètre et doit se situer dans une
fourchette de +2 à +8 °C. La précision du
thermostat permet un contrôle constant de
la température pendant le refroidissement.
