The compressor cooler can be operated on either 12 V, 24 V DC or 220-240 V AC.
Prior to connecting, check whether the voltage indicated on the manufacturer’s label is in accordance with the battery voltage. Ensure whether the circuit is in good condition and has the correct capacity to power the compressor cooler.
Press “SET” and “UP” buttons at the same time for 5 seconds to check the input power.
Under no circumstances should you try to split the wires of an extension cord.
Do not use a power strip or two-way splitter.
Never handle the plugs, leads or switches with wet hands or while standing on a wet surface.

DC:

Plug the 12/24 V DC power lead into the DC power socket on the back panel of the compressor cooler.
Connect the DC plug to cigarette lighter socket.
The compressor cooler is equipped with an electronic system to prevent reverse polarity for safety reasons. This protects the device against short circuits when connected to a battery.

AC:

When using a 220-240 V AC mains electric supply it is advisable to use a residual current device (RCD).
To connect your compressor cooler to 220–240V AC supply:
Plug in the 220-240 V AC power lead into the AC power socket on the back panel of the compressor cooler.
Connect the free end of the power lead to a 220–240 V AC supply.

When the compressor cooler is off, the power LED and the display will go blank.

NOTE: The temperature displayed on the display is the temperature inside the refrigerator compartment. The temperature may be different elsewhere in the refrigerator.

BATTERY MONITOR ADJUSTMENT WITH ANTI-LOW VOLTAGE PROTECTION SYSTEM

The device is fitted with a 3-level battery preservation monitor with anti-low voltage protection system.
It has three settings: “H1”, “H2” and “H3”, to monitor the vehicle’s battery to prevent a full discharge. The higher the setting the higher the cut-off voltage will be.
When the compressor cooler is switched on and connected to the vehicle’s power supply while the vehicle ignition is switched off, the compressor cooler will turn off automatically when the supply voltage drops below the set level. The cooler will turn on again once the battery has been charged to the voltage level required for restart.
ATTENTION! Risk of damage! If the device is shut down by the battery monitor function, the battery will no longer be fully charged. Avoid restarting the device or using it without first carrying out long charging phases. Ensure the battery is charged.
The battery monitor responds faster to the “H3” level than to the “H1” and “H2” levels.

PROTECTION SYSTEM

IMPORTANT: If the compressor cooler cuts out prematurely, this may be due to the battery protection level being set too high. Consider lowering the battery protection level.

When the compressor cooler is connected to the starting battery of your vehicle, then it is recommended to have the battery monitor set to “H3”.
When the compressor cooler is connected to an auxiliary/secondary battery, then it is recommended to have the battery monitor set to “H1”.

Connect and switch on the compressor cooler.
Press the “UP” and “DOWN” buttons at the same time for about five seconds. “H1”, “H2” or “H3” will flash on the display.
Then, press the “UP” or “DOWN” button to select the battery monitor level “H1”, “H2” or “H3”, to protect your vehicle battery. “H2” is set as default.
The selected monitor level “H1”, “H2” or “H3” will flash on the screen for a few seconds after being set and the screen will flash a few times before showing the current temperature again.

SETTING THE COMPRESSOR COOLER OPERATING MODE

To set the operating mode, tap the “SET” button twice in succession.
The letters “HH” or “ECO” will flash on the screen.
Then, use the “UP” or “DOWN” buttons to select the desired mode. The letters “HH” or “ECO” of the operating mode will flash on the display for a few seconds.
Finally, the system displays the current temperature on the screen again.

High speed (HH) mode: the temperature decreases much faster than in the ECO mode. The high-speed indicator will illuminate a red light and display “HH” when the compressor cooler is running on high speed mode
ECO mode: the compressor cooler operated in energy-saving mode. ECO mode can reduce noise from 40dB to 35dB and save energy. On the other hand, the temperature decreases more slowly than in the “HH” mode.
