Operation

Before initial use

NOTE
Before starting your new cooler for the first time, you should clean it inside and outside with a damp cloth for hygienic reasons (please also refer to the chapter “Cleaning and maintenance”

Mounting the handles

The handles are enclosed unassembled. If you wish to attach the handles, proceed as follows:

• Assemble a handle by putting two holders (1) and a handle (2) together.
• Fasten the holders with the enclosed screws in the holes provided.

Opening or removing the lid

• To open the lid, unlatch (A).
  The lid can be opened from either side.

• To remove the lid, unlatch both sides at the same time (B)

Lid stop position

The lid has a built-in stop position (A). Do not force the lid past the built- in stop (B).

NOTICE! DAMAGE HAZARD
If the lid has been forced too far, follow the steps described in the chapter “The lid has been forced past the built-in stop”

Removing the basket

NOTICE! DAMAGE HAZARD!
Removing the basket with the lid open may scratch the lid and deform the basket. We recommend to remove the lid (fig.6) before removing the basket (fig.9).

Selecting the temperature units
Temperature display units can be switched between Celsius and Fahrenheit as follows:

• Switch on the cooler.
• Press the “SET” button twice (fig. 3 5,).
• Use the “UP +” (fig. 3 7,) or “DOWN –” (fig.3 6,) buttons to select Celsius or Fahrenheit.
  ✔ The selected temperature unit then appears in the display for a few seconds. The display flashes several times before it returns to the current temperature.

Saving energy

• Choose a well ventilated location which is protected from 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.
• If the cooler has a basket: For optimal energy consumption, position the basket according to its position on delivery.
• On a regularly basis, make sure the lid seal still fits properly.
• Defrost the cooler once a layer of ice forms.
• Avoid unnecessarily low temperatures.

Connecting the cooler

Connecting to a battery (Vehicle or boat)
The cooler can be operated with 12 V or 24 V ⎓.

NOTICE! DAMAGE HAZARD
Disconnect the cooler and other consumer units from the battery before you connect the battery to a quick charging device.
Overvoltage can damage the electronics of the device.

For safety reasons the cooler is equipped with an electronic system to prevent polarity reversal. This protects the cooler against short-circuiting when connecting to a battery.

Using the fused DC plug

NOTICE! DAMAGE HAZARD
For protection of the device the DC cable supplied includes a fuse inside the plug. Do not remove the fused DC plug.
Only use the DC cable supplied.

• Plug the DC connection cable (fig. 1 2,) into the DC voltage socket of the cooler (fig.4 3, ).
• Connect the connection cable to a DC power outlet.

Connecting to an AC power supply (e.g. in the home or office

DANGER! ELECTROCUTION HAZARD
Failure to obey these warnings will result in death or serious injury.

• Never handle plugs and switches with wet hands or if you are standing on a wet surface.
• If you are operating your cooler on board a boat from a AC power supply, you must install a residual current circuit breaker between the AC power supply and the cooler.
  Seek advice from a trained technician.

The coolers have an integrated multi-voltage power supply with priority circuit for connecting to an AC voltage source. The priority circuit automatically switches the cooler to AC operation if the device is connected to an AC power supply, even if the DC connection cable is still attached.
When switching between the AC power supply and the battery supply, the red LED may light up briefly.

• Plug the AC connection cable (fig.1 3,) into the AC voltage socket of the cooler (fig.4 1,).
• Connect the connection cable to an AC power outlet.

Using the battery monitor

The device is equipped with a multi-level battery monitor that 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! DAMAGE HAZARD
When switched off by the battery monitor, the battery will no longer be fully charged. Avoid starting repeatedly or operating current consumers without longer charging phases. Ensure that the battery is recharged.

In “HIGH” mode, the battery monitor responds faster than at the levels “LOW” and “MED” (see the following table).

The battery monitor mode can be selected as follows:

• Switch on the cooler.
• Press the “SET” button three times (fig. 3 5,).
• Use the “UP +” (fig. 3 7,) or “DOWN –” (fig.3 6,) buttons to select the battery monitor mode.
  ✔ Display will be as follows:
  Lo (LOW), ΠEd (MED), Hi (HIGH)
  ✔ The selected mode then appears in the display for a few seconds. The display flashes several times before it returns to the current temperature.

NOTE
When the cooler is supplied by the starter battery, select the battery monitor mode “HIGH”. If the cooler is connected to a supply battery, the battery monitor mode “LOW” will suffice.

Using the cooler

NOTICE! OVERHEATING HAZARD
Ensure at all times that there is sufficient ventilation so that the heat that generated during operation can dissipate. Ensure that the ventilation slots are not covered. Make sure that the device is sufficiently far away from walls and other objects so that the air can circulate.

• Place the cooler on a firm foundation.
  Make sure that the ventilation slots are not covered and that the heated air can dissipate. We recommend keeping a gap of at least 50 mm around ventilation holes.
  NOTE
  Place the cooler as shown (fig.1,). If you operate the cooler in a different orientation it can be damaged.

• Connect the cooler (see chapter “Connecting the cooler”).
  NOTICE! EXCESSIVELY LOW TEMPERATURE HAZARD
  Ensure that the only those objects are placed in the cooler that are intended to be cooled at the selected temperature.

• Press the “ON/OFF” button (fig. 3 1,) for between one and two seconds.
  ✔ The LED “ ” lights up (fig.3 2, ).
  ✔ The display (fig.3 4, ) switches on and shows the current temperature.
  ✔ The cooler starts cooling the interior.

NOTE
When operating from a battery, the display switches off automatically if the battery voltage is low. The LED “ ” flashes orange.

Latching the cooler lid

• Close the lid.
• Press the latch (fig.2,) down, until it latches in place audibly.

NOTE
When latching the lid, ensure that both latch side pins are fully engaged to ensure a good lid seal. One latch may engage slightly before the other.
If the lid is not closed equally at both sides, press until a second click is heard.

Setting the temperature

• Press the “SET” button once (fig. 3 5,).
• Use the “UP +” (fig.3 7,) and “DOWN –” (fig.3 6,) buttons to select the cooling temperature.
  ✔ The cooling temperature appears in the display for a few seconds. The display flashes several times and then the current temperature is displayed again.

Setting the display brightness

The display brightness can be dimmed for low ambient light conditions. To set the dimming level of the display proceed as follows:

• Switch on the cooler.
• Press the “SET” button four times (fig.3 5,).
• Use the “UP +” (fig. 3 7, ) or “DOWN –” (fig.3 6,) buttons to set the brightness of the display.
  ✔ Display will be as follows:
  d0 (default), d1 (medium), d2 (dark)
  ✔ The display shows the set mode for several seconds. The display flashes twice before it returns to the current temperature.

NOTE

• The factory setting of brightness of the display is d0 (default).
• If a fault occurs, the brightness automatically reverts to brightness d0 (default). After troubleshooting the set brightness is reactivated.

Switching off the cooler

• Empty the cooler.

• Switch the cooler off.

• Pull out the connection cable.
  If you do not want to use the cooler for a longer period of time:

• Leave the lid slightly open. This prevents odor build-up.

Defrosting the cooler

Humidity can form frost in the interior of the cooling device or on the evaporator. This reduces the cooling capacity.

NOTICE! DAMAGE HAZARD
Never use hard or pointed tools to remove ice or to loosen objects which have frozen in place.

To defrost the cooler, proceed as follows:

• Take out the contents of the cooler.
• If necessary, place them in another cooling device to keep them cool.
• Switch off the device.
• Leave the lid open.
• Wipe off the defrosted water.
