Precautions for Use
•Structure and composition: The product consists of insulation cabinet, refrigeration system, control
system (including alarm system), data recording system and so on.
•When restarting the Transport cooler after it has not been used for a long time, the test battery may
possibly be at low level. After it is connected with power supply, the lithium battery can be charged
and it can be fully charged after Transport cooler's working for continuous 5 hours.
•The indicated temperature value of the Transport cooler is the value indicated at the temperature
sensing probe inside the Transport cooler. Occasionally there is a certain difference between the
indicated temperature and the actual temperature in the central part of the Transport cooler, but it will
gradually approach to the true temperature.
•Use the diluted neutral detergent to clean the refrigerator. Do not use brushes, acid, gasoline,
soap powder, polishing powder or hot water to clean the Transport cooler as the above-mentioned
materials may damage the painting surface as well as the plastic and rubber parts and components.
Take particular care not to use volatile solvent such as gasoline to wipe plastic and rubber parts and
components.
•Cut off the power of the Transport cooler when it will be out of service for a long time.
•Every time when putting in and taking out the articles, please try to reduce the door opening time so
as not to cause relatively large fluctuations of the temperature and humidity inside the heating box.
•After the door is opened, the temperature inside the refrigerator will rise steeply in a short time. This
is normal and the temperature will restore within one hour after the door is closed.
•Semiconductor is used in the transfer box for refrigeration. Compared with compressor refrigeration
products, the cooling time is longer.
