Maintenance of the
VLS SDD appliance
Daily maintenance:
The temperature in the vaccine compartment
must always be monitored on the thermom-
eter every morning and evening. Please
note that the vaccine in the appliance may
not freeze. The temperature is factory set,
and should not be adjusted by unauthorized
personnel.
Check lid is properly closed and fits tightly to
the cabinet of the appliance.
Monthly maintenance:
Clean the grille on the back side of the refrig-
erator once each month.
Yearly maintenance:
Electric connections and components are to
be checked and cleaned once a year or more
if necessary.
Maintenance of the solar panels
Weekly maintenance:
The solar panels are to be cleaned for dust
once each week – or as required. Cleaning
must be carried out with water using a soft
cloth or wash rag.
Monthly maintenance:
Avoid shading
It should be regularly monitored that shades
do not come up such as new towering trees,
as this will decrease the amount of energy
produced by the system.
Yearly maintenance:
Electric connections and components are to
be checked and cleaned at least once a year
or more often if required. Because of risk of
fire, it is necessary to remove dust and dirt.
Checking that PV panels are clean, free of
fractures, scratches, corrosion, moisture
penetration and browning.
Cabling should be checked to ensure it is
secure.
Checking the mounting hardware to ensure
it is in good condition and ensuring the earth
connection is continuous.
Checking of junction boxes to ensure there is
no water accumulation and that the integ-
rity of lid seals, connections and clamping
devices is intact.
All bolts and nuts are to be re-tightened 2
weeks after installation, and then once a year.
Cleaning
Disconnect the power supply before cleaning
by using the on/off switch placed in the front
of the appliance. 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 the appliance off,
disconnect the power supply, empty the
appliance, clean the inside, and leave the
lid open to allow air circulation and prevent
smells.
