walls. This is also where you can find your serial number. You should note these
down in this manual and keep this manual handy.
2. Check the sizes on the chart match closely the size of the refrigerator. You should
expect approx. 5 mm difference in size on the chart to the external dimensions of the
fridge box. Measure 2, 3, or more times, and recheck before making your cuts. (Nova
Kool is not liable for incorrectly measured cut-outs resulting in difficulties in being
able to install your unit).
3. When cutting out your ventilation holes, ensure there are no structural beams or
electrical cables where you are making the cut. Make sure the ventilation holes are of
sufficient size to allow the fridge to breath properly. (Nova Kool is not liable for
incorrect /inadequate ventilation or holes cut in the incorrect position)
4. When running the power supply cable from the battery to the rear of the fridge
compartment follow the shortest possible route. Ensure there is enough cable for
you to connect the refrigerator when the unit is external to the cavity. Ensure that
you have a fuse fitted very close to the battery, no more than 15 cm from the battery
terminal. (Nova Kool or Ocean Solutions International are not liable for incorrect or
poor electrical wiring in your installation)
5. Ensure the fuse is out in your wiring and your wiring is not connected to the battery.
6. Connect the refrigerator side of your power supply cables to the refrigerator
electrical terminals, located on the electronic control module (ECU).
7. Place refrigerator into the cut-out, ensuring not to pinch or jam the cables.
8. Screw the refrigerator into the cut-out by fixing the screws at an angle slightly
pointing away from the refrigerator, in the screw holes in the mounting flange, and
tighten the screws to hold the refrigerator firmly in place.
9. Look through your ventilation holes and ensure all your cables are clear of any
obstruction points, and all cable connectors are firm. It is advisable to loop your
power input cables above the ECU and cable tie the loop so that there is no
downward pressure on the power supply input cables (vibration and downward
weight pressure when travelling can loosen and sometimes disconnect your cabling
from the ECU terminals which results in a non-powered appliance.
10. Fit your ventilation covers as per the ventilation covers instructions.
11. If you have a mechanical thermostat, open the refrigerator door, and turn the
thermostat dial to "0"
12. Connect the cable to the battery, and place the fuse into the fuse holder
13. Open your refrigerator door and turn your thermostat to between '3' and '4'. For
double door units we recommend a starting point of '4.5' on the thermostat.
Your refrigerator will now be running and starting to cool down. This can take several
hours, and best to leave over night to allow the temperature to settle. It's a good idea to
have a thermometer (Or better still, a temperature and humidity data logger) sitting on the
bottom shelf and read it in the morning. This will assist you in setting the correct
temperature of your refrigerator.
