Installation instructions
Mount the box carefully and safe. It is vitally important,
on air cooled units, that the compressor and the
condenser are well ventilated and that cold air can
enter from below and warm air can leave the space
around the compressor unit. (Warm air is leaving
upwards).
Do not install the box close to warm areas as the stove,
heater or the engine.
See the separate additional installation instructions for
Isotherm SP when the refrigeration unit is equipped
with an SP through hull fi tting/heat exchanger and also
the separate installation instructions valid for boxes
having a “Magnum” compressor unit water cooled with
water pump.
Electrical connections
When connecting the box 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.
Wire area
mm² AWG
Max wire length
12V m / ft
Max wire length
24V m / ft
2.5 12
2.5 / 8
5 / 16
4 10
6 / 18
12 / 32
6 10
10 / 32

* Always connect the box 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 suffi cient size for the cable size
selected.
* Do not connect the box direct to a battery charger.
The battery charger must be connected to the
battery.
