Low Voltage Protection - Indel Webasto Marine Isotherm DR70 Instructions Pour L'installation Et L'utilisation

To keep the surface of the door in good conditions and intact, make sure that it is
always dry and clean.
In order to prevent damage to the electrical/mechanical components and/or the
formation of mould, when shutting off the refrigerator for extended periods of
time it is necessary to wait for the unit to defrost completely and to eliminate any
condensation that may have formed, both inside the unit and in the external water
collection tray. The natural defrosting time can vary from a few minutes to several
hours. In the wintertime and when the refrigerator is shut off, the door should be left
slightly ajar for ventilation and all power disconnected.

3.1 Low voltage protection

In order to prevent excessive battery depletion, a protection device shuts off the
compressor in case of insufficient voltage and turns it back on when the voltage in
the system increases after the batteries have been charged.
