Key Product Features:
The most reliable portable cooling system in the world – Powered by Danfoss.
Danfoss electronics, high efficiency, low energy consumption.
Multi-voltage system DC (12 and 24 Volt ) and AC (100-120/220-240 Volt)
Adjustable battery protection helps protect your battery (DC only).
1. Safety Instructions
Warning: Do not use your unit if any cabling is damaged, frayed or there is exposed
wiring.
Warning: Do not attempt or continue to operate your unit if it is wet.
When using the unit ensure the circuit being used has a fuse or circuit breaker,
recommended size for DC 12 Volt is 15 Amp, DC 24 Volt is 7.5 Amp and AC is 4
Amp.
Make sure the voltage is within the correct range for socket and cable being used.
The technical data label on the side of the unit shows the voltage ranges.
Do not place any electrical devices inside the refrigerator as they may be damaged.
2. Notes on using the product
o Your unit requires good ventilation, especially around the back of the refrigerator; allow a
gap of at least 100mm around all sides.
o Do not allow a large amount of frost to build up on the inside walls as this may impair
cooling. Defrost by turning the unit off, allowing the frost to melt and wiping out the
water.
o The lower the ambient temperature, the lower the power usage, in order to maximize
efficiency keep the unit in a cool location out of direct sunlight.
o It is recommended to operate the unit on a flat surface, but it will operate at angles up to
30º.

3. Operation
o Power：Both DC (12 and 24 Volt) and AC (100-120/220-240 Volt) can be connected to
your unit at the same time. In this case, AC will be the preferred power supply
source. If the AC power supply is disconnected or becomes outside the correct
voltage range, after a 1 minute delay your unit will start to operate on DC power.
Once AC power is re-established or returned to the correct voltage range the unit
will start to operate on AC power without delay.
o Battery Protection: Selecting the Low, Med, High positions of the switch (next to the
DC power socket), you can choose different levels for battery protection. In the
below table you can find the voltages when the compressor stops running (cut-out)
and when the compressor restarts working (cut-in).
o Cable Length Specification
The DC cables must have a suitable cross-section for their length (measured from the battery
to the unit), according to this table:
