Display & control panel

Display & Control Panel

Cooler device switch on/off

Switch on: Touch the button «ON/OFF» once lightly by your finger.
Switch off: Keep touching the button «ON/OFF» for about five seconds.

Cooling temperature setting

Switch on the cooling device.
Select temperature display unit: First touch the button «DOWN» without releasing, at the same time use your another finger to touch the button «SET» without releasing, keep your two fingers touching the two buttons «SET» and «DOWN» for about 5 seconds, there will be flashing «°C» or «°F» appearing in the display screen, release your two fingers from the two buttons «DOWN» and «SET». Then touch the button «UP» or «DOWN» to select the temperature unit Celsius or Fahrenheit. The selected temperature unit will appear and flash in the displayscreen for a few seconds, and then the display screen will return to display the current Temperature automatically.

Setting the temperature in models with a single control:

Touch the button «SET» once, then touch the «UP+» and «DOWN-» button to set the cooling temperature you want. A change in temperature in the freezer leads to a corresponding change in temperature in the cooling compartment.
The selected temperature number will flash in the display screen for a few
seconds, and then the display screen will return to display the current temperature automatically.

Setting the temperature in models with independent control:

Press the «SET» button once and use the «UP+» and «DOWN-» buttons to set the desired temperature in the freezer.
Press the «SET» button twice and use the «UP+» and «DOWN-» buttons to set the desired temperature in the cooling chamber.

Low voltage protection battery monitor setting

The cooling device is equipped with a 3-level battery monitor which protects your vehicle battery against excessive discharging when the device is connected to the on-board DC supply.
If the cooler is operated when the vehicle ignition is switched off, the cooler switches off automatically as soon as the supply voltage falls below a set level. The cooler will switch back on once the battery has been recharged to the restart voltage level.

NOTICE! Danger of damage!

When switched off by the battery monitor, the battery will no longer be fully charged.
Avoid starting repeatedly or operating without longer charging phases. Ensure that the battery is recharged.

In «H3» level, the battery monitor responds faster than at the level «H1» and «H2».

When the cooler is supplied by the started battery, select the battery monitor level «H3», if the cooling device is connected to a supply battery, the battery monitor level «H1» will suffice.

Switch on the cooling device.
There are 3-level low voltage protection battery monitor setting: H1, H2 and H3.
Press and hold the «UP» and «DOWN» buttons for 3 seconds to select the battery monitoring level H1, H2 or H3 .

Energy saving tips

Choose a well-ventilated installation location which is protected against direct sunlight.
Allow warm food to cool down first before placing it in the cooling device to keep cool.
Do not open the cooling device more often than necessary.
Do not leave the cooling device open for longer than necessary.
Defrost the cooling device once a layer of ice forms.
Avoid unnecessary low temperature.

CONNECTING THE COOLING DEVICE

WARNING! DC extension cord

Because of the potential safety danger under certain conditions, the manufacturer does not recommend using any type of DC extension cord.
Under no circumstance should you attempt to splice extension cord wires.
Do not use power strips or two-way splitter.
Always unroll or uncoil a DC cord to avoid heat retention and possible melting.
Connecting to a battery (vehicle or boat), the cooler can be operated with DC 12V or 24V.
NOTICE! Danger of damage!

Disconnect the cooler and other consumer units from the battery before you connect the battery to a quick charging device. Over-voltage can damage the electronic of the cooling device.
For safety reason, the cooling device is equipped with an electronic system to prevent polarity reversal. This protects the device against short-circuiting when connecting to a battery.

Using the fused DC plug for device connection

NOTICE! Danger of damage!

For protection of the device, the DC cable supplied includes a fuse inside the plug.
Do not remove the fuse from the DC plug. Only use the DC cable supplied.

Plug the DC cable into the cooling device DC power supply inlet.
Connect the DC cable to the DC power supply outlet.

USING THE COOLING DEVICE

Switch on the cooling device

NOTICE! Danger of overheating!

Ensure at all time that there is sufficient ventilation so that the heat which generated during the operation can dissipate. Ensure that the ventilation slots are not covered. Make sure that the device is sufficiently far away from walls and other object so that the air can circulate.
