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.

Fig. 4

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.
