This handbook is published by the World Health Organization Expanded programme
on Immunization.
It is general handbook for use by service and repair technicians responsible for the
maintenance and repair of solar photovoltaic powered refrigerator.These
refrigerators are used for storing vaccines and freezing ice packs in health clinics.
This handbook applies specifically to 12 to 14 volt stand-alone photovoltaic powered
refrigerators and should not be used for any other type of refrigerator. Stand-alone
means here that the solar array does not power any other device (e.g. lights) and
refrigerator it powered only from the solar array.
The handbook should be considered a supplement to maintenance and repair
manual supplied by the solar refrigerator manufacturer, which define maintenance
and repair activities specific to their model of refrigerator.

You should ensure you have copies of the USERS HANDBOOK in case a user
responsible for a solar refrigerator you visit does not have one.
