• To ensure proper function, the device must be
standing horizontally. Use a water level to
check and to correct if necessary.
• The TCW3000SDD is equipped with bearing
rolls. Once it is in its final position, the feet
must be screwed up to immobilise it and stop it
rolling away. Screw the feet with the provided
key until the rolls do not touch the floor
anymore.
• Make sure that during operation the drainage
plug is closed properly.
CLEANING / DISINFECTING
• Clean or disinfect the unit inside and outside before using it. Use only gentle cleaning agents. Never
use aggressive or caustic cleaning agents, scouring powder, steel wool, abrasive sponges or
chemical solvents. When cleaning, make sure that no fluids of any kind run into the ventilation
housing.
• For disinfecting, we recommend all the surface disinfecting agents commonly used by the customer,
provided they are recommended by the German Association for Hygiene and Microbiology (DGHM) or
other national organisations. For disinfecting small areas, we recommend using a concentrated
alcoholic agent.

OPERATION
TEMPERATURE-DISPLAY
• In normal use, the display shows the inside temperature of the appliance. This temperature is
displayed in °C with one decimal place.
• During times without solar energy supply or in case of power failure the display is switched off. The
inside temperature can be checked by pressing the “TMP” button.
TEMPERATURE-SETPOINT
• The temperature setpoint is preset at +5.0°C and cannot be changed by the user.
• Press the SET-key to view the actual temperature setpoint.
STORAGE OF VACCINES
IMPORTANT :
When using the TCW3000SDD, it is of utmost importance that the icelining waterpacks are in
place. Make sure that all waterpacks are in place before starting the TCW3000SDD in refrigerator
mode. Never remove the waterpacks from the unit.
Special care should be taken to preserve the vaccines that get damaged by freezing. Never store
them touching the side surfaces in the cabinet of a TCW3000SDD. It is advisable to preserve the
vaccines in the provided baskets.
For storing vaccines :
• Keep the packets containing the vaccines in
neat rows.
• Different vaccines should be kept separately to
facilitate easy identification.
• Keep about 2 cm space between rows for
circulation of air.
• Do not load vaccines higher than the indicated
maximum level.
USING THE TCW3000SDD
• Install the TCW3000SDD as detailed under “Installation”.
• Shift the ON/OFF-switch to position “I”. The temperature display lights up to show that the unit is
ready for operation.
• After switching on, the compressor only starts after a delay of 3 minutes. This also applies, if the
equipment is switched off and on again.
• Close the lid and allow the unit to run. The temperature inside the cabinet is indicated on the
display. Observe the temperature from time to time.
• Initially the temperature inside the TCW3000SDD will be observed to be similar to or slightly below
the room temperature. It will decrease slowly and remain steady after several days.

• In order to assure a complete freezing of the icelining waterpacks it is advisable to start loading the
TCW3000SDD with the vaccines after 1 week of operation.
• When the temperature inside is observed to be
steady for several hours within the required
range, only then the vaccines to be preserved
should be transferred to the TCW3000SDD.
• The vaccines are advised to be kept in the
baskets provided.
• After storing the vaccines keep the lid properly
closed and locked.
• When fresh vaccines are stored in the
TCW3000SDD, the cabinet temperature may go
up initially but should fall and come to the
required range after few hours.
• The cabinet temperature may vary depending
upon various factors, such as,
• the ambient temperature
• the intensity and duration of solar radiation
• amount of vaccine preserved in the TCW3000SDD
• frequency of lid opening
• circulation of air around the TCW3000SDD
CONDENSATION WATER
• The moisture in the air, which enters the cabinet due to lid opening is attracted by the cold surfaces
inside. The moisture will condensate on these cold surfaces. The condensation water is collected at
the bottom of the inner cabinet and must be
evacuated on a regular basis (at least once a
week) using the drainage plug on the front side of
the cabinet.
• Open the drainage plug at the bottom front side
the cabinet. Keep a suitable container under the
drain hose to collect the water.
• Close the drainage plug after all water is
evacuated.
CLEANING
IMPORTANT :
Before cleaning the TCW3000SDD, the vaccines preserved in it will have to be removed and stored
temporarily in other working refrigerator. If a second refrigerator is not available, the vaccines
will have to be preserved in Cold-Box or Vaccine carrier.
• Switch off the TCW3000SDD and disconnect it from power supply.
• Prepare the temporary storage and transfer the vaccines and preserve them properly with care.
• Gently remove the cabinet frame and the complete inner liner by holding it on its two opposite sides
and lifting it uniformly.
• Clean all parts inside and outside the cabinet, the lid and the lid gaskets with warm water and mild
detergent. Allow the cleaned parts to dry completely.
• Examine the waterpacks for any leakage. A defective waterpack will have to be replaced.
• After the evaporator surface is free of condensation water, put back carefully the inner liner into its
position.
• Replace the cabinet frame.
• Close the lid. Connect the power supply and switch on the TCW3000SDD.
• Allow it to run and observe the cabinet temperature on the display.
• Put back the vaccines into the TCW3000SDD from the temporary storage, only when it has attained
safe recom mended temperature range for storage of the vaccines.

PERIODIC MAINTENANCE
DAILY
• Take temperature readings and note down the temperature and the time of reading. Keep the
temperature records systematically. It is suggested that minimum 2 readings should be taken (in the
morning and afternoon) preferably at the same hours of each day.
WEEKLY
• Evacuate the condensation water as described before.
• If it is observed that quantity of condensation water is increased :
• Examine the gaskets on the lid, if they sit properly. Any gap between the cabinet and gaskets will
allow outside air to go in and form condensation. In such cases the hinges should be adjusted
or the gaskets should be changed.
• Restrict and reduce frequency of opening the TCW3000SDD. Open only when absolutely
necessary.
MONTHLY
• Clean the unit from any dust :
• Switch off the TCW3000SDD and disconnect it from power supply.
• Clean the condenser on the back side of the unit with a soft brush or a vacuum cleaner.
• Clean the lid seal.
TROUBLE SHOOTING
IMPORTANT :
If a TCW3000SDD is found to be not working at all or not working properly see that the vaccine
temperature is within the recommended limits. Do not open the lid unless very essential.
For any abnormal sound, smoke, smell etc. in the TCW3000SDD disconnect from the power supply
and notify refrigerator technician.
The electronic displays an error message :
F1/ F2 : Probe failure. The unit will continue to work in “ON/OFF-mode” to keep the temperature in the
desired range - notify Refrigerator Technician.
E1 : Voltage protection cut-out. The voltage is outside the cut-out setting - check power supply.
E3 : Compressor start error. The compressor cannot start. Keep the unit switched on. This problem
might occur if the solar generator doesn’t deliver enough power (cloudy day, shadow on solar
panels, bad positioning of solar panels etc.). Check the actuals situation of the panels, and if the
problem persists after necessary corrections, notify Refrigerator Technician.
E4 : Minimum compressor speed error. Keep the unit switched on. This problem might occur if the
solar generator doesn’t deliver enough power (cloudy day, shadow on solar panels, bad
positioning of solar panels etc.). Check the actuals situation of the panels, and if the problem
persists after necessary corrections, notify Refrigerator Technician.
E5 : Thermal cut-out of electronic unit. The ambient temperature is too high, the electronic unit will
run too hot. Switch the unit off. If after one hour the problem still persists, notify Refrigerator
Technician.
