4.2 Ventilation

It is extremely important for the compressor/condensing unit located behind the
refrigerator to be well ventilated so that the fresh air can enter at the bottom and
pass behind the refrigerator, with the hot air being allowed to escape from the top or
sides.
The illustrations (Fig.1-2) show an example of how the refrigerator housing should be set.

4.3 Electrical Connections

• In order connect the unit to the vehicle's electrical system, proceed as follows:
• Before turning on the appliance, check to make sure that the voltage of the
electrical system and/or battery complies with that which is indicated on the
unit's data plate.
• Connect the refrigerator directly to the battery or to the relative main switch and
make sure that the system is equipped with an electric device that's capable of
protecting the circuit against possible overcurrents.
If the power supply voltage is different from 12/24Vdc, install a ΔI 0.03A differential
circuit breaker. Avoid connecting the unit via the vehicle's control panel as this could
result in voltage drops.
• Insert a fuse upstream from the refrigerator (see the table below). Connect the
red wire to the electrical system's positive terminal, and connect the black wire
the negative terminal. Use a pressed lug terminal that's suitable for the cable's
size.
• A separate switch that simultaneously disconnects the power cables must be
installed upstream from the refrigerator. Check to make sure that the installed
switch supports the corresponding load indicated in the table below.
