Ventilation; Electrical Connections - Isotherm BI29 Dual Instructions Pour L'installation Et L'utilisation

5.2 Ventilation

Make sure that the compressor/condensing unit is well-ventilated so that the fresh
air can escape from the top.
The illustrations (Fig.1-2) show an example of how the product housing should be set.

5.3 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 product 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 product (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 product. Check to make sure that the installed
switch supports the corresponding load indicated in the table below.
