It is very important that the compressor/condenser unit is well ventilated and that cold air can enter at the bottom, pass behind the fridge and warm air can leave at the top in the area where it is mounted. The natural flow of air from below and upwards behind the fridge can be increased by arranging  ventilation openings at the rear. Make sure there is a free area of 15 - 23 sq.in. below and behind the refrigerator to allow ventilation air to pass behind from below. (see diagram below).

Electrical Connections:
When connecting the refrigerator electrically, it is important that following points are considered:
Always use cables of suffi cient area. The area in the following table should be regarded as a minimum. * Always connect the refrigerator directly to the battery or to the battery main switch on the plus circuit. Do not connect it via the boats own control panel or other diversions as this can cause a voltage drop in the power supply. Use the included fuse holder with a 15A fuse. Use 7.5A fuse in a 24 volt system. The fuse shall be mounted on the plus cable.
*Connect the red cable to the positive (+) terminal and the black to the negative (-) terminal. Use tab type terminals for the connection to the electronic unit and other cable connectors of sufficient size for the cable size selected. * Do not connect the refrigerator direct to a battery charger. The battery charger must be connected to the battery.

Battery Voltage (Shut Down) Sensor:
To protect the batteries from becoming completely discharged, a battery voltage sensor switches off the compressor automatically at the following levels:

Wire Dimensions:
The correct wire gauge  and type must be used.
