4.6 Energy saving tips
•
Choose a well-ventilated installation location which is protected against direct sunlight.
• Allow warm food to cool down first before placing it in the cooling device to keep cool.
• Do not open the cooling device more often than necessary.
• Do not leave the cooling device open for longer than necessary.
• Defrost the cooling device once a layer of ice forms.
• Avoid unnecessary low temperature.
5. CONNECTING THE COOLING DEVICE
WARNING! DC extension cord
Connecting to a battery (vehicle or boat), the cooler can be operated with DC 12V
or 24V.
Under no circumstance should you attempt to splice extension cord wires.
Do not use power strips or two-way splitter.
Always unroll or uncoil a DC cord to avoid heat retention and possible melting.
NOTICE! Danger of damage!
Disconnect the cooler and other consumer units from the battery before you connect
the battery to a quick charging device. Over-voltage can damage the electronic of
the cooling device.
For safety reason, the cooling device is equipped with an electronic system to
prevent polarity reversal. This protects the device against short-circuiting when
connecting to a battery.
