device.
•Only approved vaccines or medical supplies should be stored in the refrigerator. Do not
store any foods, beverages, or flammable, explosive, volatile items (such as alco hol or
gasoline) or other dangerous items in device.
Cool Down
Step 1: Co
nnect the specified solar panel
and switch on.
Step 2: Once powered on, the temperature display will show the internal temperature. The
cooling system will start.
Step 3:
Do not use the
device until the display indicates that the inner temperature is stable
near 4°C, which usually takes 4 days of consecutive solar cycles..
Step 4:
In the case of intermittent
solar
power (≤4 hours of power each day) and high
ambient
Step 4:
In the case of intermittent
solar
power (≤4 hours of power each day) and high
ambient
temperature environment, the device may require 2 additional days after initial installation
to reach full holdover capability.
Note: In case of cloudy or rainy day, the device may require more time to reach stable state .
Daily Use
You can deal with the vaccine storage work when the device’s inner temperature is stable. Do
not store vaccines until the device's inner temperature is stable between 2 °C and 8°C.

These vaccine stacks are designed to be stacked together within
the device. There are large and small cups, and the cups can be
stacked in different configurations, forming a total of 6 stacks

4 square stacks and 2 triangular stacks.
Each stack has a black nylon handle. The handles make it easy
to lift the vaccine stacks.

Set up vaccines, daily or weekly
There is a designated “day use” cup, located in the top -
most
accessible position in the device, designed to hold all of the
vaccine vials needed for the day. The “day use” cup is designed
to be easily accessible when the device is opened.

“Day Use” Cup
to be easily accessible when the device is opened.
To administer the vaccines efficiently, you can arrange the
vaccines in the designated “day
-
use” cup so that they will be
easily accessible throughout the day.
This process can be done daily or weekly – depending upon the
volume of vaccine usage. If possible, to minimize warming of
the vaccines, arrange the cup stacks in the morning, when the
surrounding ambient temperature is the lowest. The vaccine
stacks should only be removed during this routine set-up time,
not during the day when you should simply be acces
sing

CLEANING AND STORAGE
Cleaning
Note: For safety reasons, worker should turn off the power switch before starting the cleaning
work. Do not use wet cloth to wipe any electrical parts or touch any electrical components
(such as plugs, switches, etc.) with wet hands in order to avoid electric shock.
The exterior of the device can be cleaned as needed.
The interior
of the device should be cleane
d after removing everything from the device.
To clean the exterior of the device:
1.
Wash the device with a sponge or soft cloth.
2. Soap and water can be used. However, do not use abrasives or cleaning powders.
3. Dry the device with a towel or allow it to air dry.
The dust screen
needs to be checked and cleaned every week.
This step helps to dissipate
heat better.
The dust filter must be cleaned at a minimum every week or more often if necessary
.

To clean the interior of the device
1.
Use caution near the wires on the interior of the device; these are for the sensors that
monitor the internal temperature of the device.
2. Remove the device’s cap. The cap will remain tethered to the device.
3. Remove the vaccine stacks. Follow established cold chain vaccine handling practices with
any remaining vaccines.
4. Clean the cups that comprise the vaccine stacks with soap and water, if needed, and let
dry.
5.

8. When the interior of the device is drying, the device’s cap may be removed. However, if
the device is going to be used
, it s
hould be stored with the cap closed
.

To clean the
solar panel
The front of the solar panel
must be cleaned every week or when necessary in dusty areas.
Use water and soft rag to clean. Do not use corrosive solvents. You need to use a duster as
primary tool
when it
’s not easy to get (on the pole).
Note: Please turn off the solar power switch (on wall) before cleaning.

Small amounts of water in the device do not pose a problem. Do not
remove vaccine stacks to clean up water, as this will cause unnecessary
warming and negatively affect vaccine hold time. Until cooler part of
the day, when
the device i
