Voltage stabilizers
It is highly recommended that all cold chain equipment running on AC current is installed with a voltage stabilizer, in order to safeguard the equipment against voltage fluctuations.
Stabilizers should be selected & installed as per the input voltage available.
Instructions to User:
- Every refrigeration unit must be connected to an individual stabilizer.
-
Bypassing of Stabilizer is not recommended, 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 immediately. Identify authorized Vestfrost service provider in case of technical assistance is required.
The voltage stabilizer is also provided with arrangement to cut off its output voltage to the ILR in case the mains voltage goes below or above as per designed input voltage range. The output is restored automatically after the factory set delay 3 to 6 minutes (WHO/PQS E007/VS01.4 specifications) when the mains voltage is within the recommended range and remains within.
Connect the appliance to voltage stabilizer and connect voltage stabilizer to wall socket. Do not use extension cords.

(Fig 9+10)
fig. 9
Electrical connection
Wiring and connections in power supply systems must be all applicable to (local and national) electrical codes. Consult these code lengths and sizes prior to cabinet installation.

Operation and function

The green lamp is on when the appliance is connected to the power supply.
Starting procedure
Connect the mains lead to the power supply /voltage stabilizer.. The green lamp must light (fig. 11) to 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 twice a day. The inside temperature must be checked regularly according to WHO's standards and specifications.
Cool down of the appliance
Before the appliance is loaded with vaccines the ice-lining must be frozen. To ensure that the ice-lining is frozen do the following:
- Place a thermometer in the top basket.
- Let the refrigerator run for at least 48 Hours before loading vaccine.
- Check the temperature in the vaccine compartment (must be between +2^ and +8^ ).
The temperature in the vaccine compartment must always be monitored on the thermometer and be within the range +2^ to +8^ . Due to tolerance of the thermostat you should always control the temperature during cool down.
Controller
The appliance has a controller that controls the temperature in the vaccine compartment. The controller is factory adjusted to a default setpoint, what in most ambient environments will keep the vaccine compartment within desired thresholds of 2^ - 8^ .
If the cooler is not used for a longer period of time, it is recommended to use the
ON/OFF switch turn the cooler OFF. This disconnects the power from mains In case cooler is turned OFF, make sure the vaccine compartment is cleaned and dried thoroughly afterword's, this to prevent problems with odors or mold. To prevent odors taking hold it is highly recommended to keep the lid slightly open.


fig. 13
Start up
Before the appliance is loaded with vaccine, the ice-lining must be frozen. The cooldown time in an ambient temperature of 43^ will be approx. 5-7 days.
When the temperature on the display of the thermometer is approx. +4^ in the morning, the appliance is ready for loading vaccine. Check the temperature in the basket. The temperature must be between +2^ and +8^ .
The vaccines must be placed and arranged as shown on page 12, fig 15.
The temperature in the vaccine compartment must always be monitored on the thermometer and be between +2^ and +8^ . The controller is factory set and should not be adjusted by unauthorized personnel.
Loading the appliance
Loading vaccines
When the temperature in the vaccine compartment has stabilized, i.e. and the temperature is between +2^ and +8^ and the compressor stops and starts, vaccines can be loaded. The vaccines should be placed and arranged in the baskets.
To ensure air-circulation and prevent too low vaccine temperature, direct contact to the inside walls must be avoided. The Vaccine load in the baskets shall not be above top of the baskets.(fig.15)
Vaccine storage
Below points are recommended vaccine storage advice outlined by Unicef
- Keep the vaccine boxes containing the vaccines in neat rows.
- Different vaccines should be kept separately to facilitate easy identification.
- Keep about, 2cm space between boxes of vaccines for circulation of air.

fig. 14
- Store Freeze sensitive vaccines (DPT, TT, IPV, Penta and Hep. B) away from the bottom of the ILR to avoid freezing. Always keep the vaccines in the basket provided in the ILR. OPV, RVV BCG, JE and Measles vaccine to be storedat bottom of basket of the ILR.
Vaccine should be stored as per their heat and cold sensitivity.
Do not load the vaccine above top of the handle on the basket.

fig. 15
Maintenance and cleaning
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 must 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 off water droplets on the inside wall at the same time.
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 formation of rime significantly.
Monthly maintenance:
Clean the grille on the right side of the refrigerator once each month. Clean vaccine compartment with lukewarm water and mild detergent Clean outside of refrigerator with lukewarm water and mild detergent
Yearly maintenance:
Electric connections and components are to be checked and cleaned once a year or more if necessary.
Cleaning
WARNING:
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 gasket 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 bad odor.
Condensation water drainage
Due to humidity in the air combined with cold surfaces inside the vaccine compartment, it should be expected that condensation will form on the sides of the inner lining. The condensation will be collected at the bottom, from where it regularly needs to be drained. If the bottom of the vaccine compartment is covered with condensation water, drainage/drying should be initiated.
Condensation increases if:
- Equipment is opened too frequently.
- Lid not closing properly.
- Lid gasket is defective.
High level of humidity.
Drainage of condensation water is recommended to performed in the morning between 7am to 9am when the ambient temperatures are expected to be lowest. Proceed as follows:
IMPORTANT!
Before condensation drainage vaccines must be moved to another working ILR or cold box with conditioned icepacks.
- Disconnect the power supply by switching off the ON/OFF power button or disconnect plug from power socket.
- Open the drainage plug, placed inside the vaccine compartment.
-
Place a tray under the condensation water drain.
-
When all the condensation and water droplets on the lining has been removed carefully, clean the inside cabinet, as well as lid, lid gasket, and outside of the cabinet, using water with a mild, perfume-free detergent. Dry the vaccine compartment with a soft cloth, and make sure, no moisture is remaining after cleaning.
- Reinsert the internal drainage plug, and check lid gasket is not faulty.
- Reconnect the power supply by the ON/OFF power button and/or reconnect power plug.
- When appliance has regained required safe temperatures for storing vaccines 2^ - 8^ place the vaccines in neat rows with space.
