Installation
The refrigerator should be located and secured on a solid surface in the vehicle.
Before installing the refrigerator into the opening, make sure the DC supply is properly
connected. In many cases, the DC supply can be connected from outside the vehicle
by means of the baggage or access door.
Measure the opening to determine if you have proper clearance for installation.
Additional insulation space around the refrigerator is not necessary.
For your reference
The wiring diagram shown below is recommended for dual battery hookup (See
