Dometic Basement Cooler

Operating the cooling device safely

Caution

Before starting the cooling device, ensure that the power supply line and the plug are dry.

 

Notice

Do not use electrical devices inside the cooling device unless they are recommended by the manufacturer for the purpose. Do not place the cooling device near naked flames or other heat sources (heaters, direct sunlight, gas ovens etc.). Danger of overheating! Ensure at all times that there is sufficient ventilation so that the heat that arises during operation does not build up. Make sure that the cooling device is sufficiently far away from walls and other objects so that the air can circulate. Ensure that the ventilation openings are not covered. Do not fill the inner container with ice or fluid. Never immerse the cooling device in water. Protect the cooling device and the cable against heat and moisture.

Before initial use

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

• Make a handle by putting two holders (fig.4 1) and a handle (fig.4 2) together.
• Fasten the grip with the enclosed screws in the holes provided.

Selecting the temperature units

You can switch the temperature display between Celsius and Fahrenheit. This is how to do it:

• Switch on the cooler.
• Press the “SET” button (fig. 2 4) twice.
• Use the “UP +” (fig.2 6) and “DOWN -” (fig.2 7) buttons to select Celsius or Fahrenheit.
• The selected temperature units then appear in the display for a few seconds. The display flashes several times before it returns to the current temperature.

Reversing the lid opening direction

The lid hinges can be moved to the opposite side if you want to open the lid from the opposite direction. To do this, proceed as follows:

• Open the latches.
• Remove the screws from the latches and take off the latches (fig.5 1).
• Remove the screws from the hinges and take off the lid (fig. 5 2).
• Re-fit the hinges in the new positions.
• Re-fit the latches in the new positions.

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 temperatures.

Connecting the cooler

AC extension cord

Warning

Because of potential safety hazards under certain conditions, the manufacturer strongly recommends against the use of an extension cord. However, if you must use an extension cord, it is absolutely necessary that it be a UL-Listed (in the United States) or a CSA-Listed (in Canada) appliance extension cord, with 10 A (minimum), 120 V electrical ratings.

Caution

Under no circumstances should you attempt to splice extension cord wires. Do not use power strips or 2-way splitters. Always unroll or uncoil an extension cord to avoid heat retention and possible melting.

• Select a UL/CSA listed 120 Vw/≥ 10 A outdoor use extension cord according to the following table:

	Maximum cord length
120 V	10 ft. (3 m)	25 ft. (7.6 m)	50 ft. (15.2 m)	100 ft. (30.5 m)
Wire conductors	3	3	3	3
AWG	14 (1.6 mm²)	12 (2 mm²)	12 (2 mm²)	12 (2 mm²)

DC Extension Cord

• Select a 12 V/24 Vg/≥ 10 A automotive use extension cord according to the following table:

	Maximum cord length
12 V	3 ft. (0.9 m)	6 ft. (1.8 m)	10 ft. (3 m)	12 ft. (3.7 m)
24 V	6 ft. (1.8 m)	10 ft. (3 m)	15 ft. (4.6 m)	25 ft. (7.6 m)
AWG	14 (1.6 mm²)	12 (2 mm²)	10 (2.6 mm²)	8 (3.3 mm²)

Connecting to a battery (vehicle or boat)

The cooler can be operated with 12 Vg or 24 Vg.

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

• Plug the DC connection cable (fig.1: 2) into the DC power supply inlet of the cooler (fig. 3: 3).
• Connect the connection cable to the DC power outlet.

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

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 power supply 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 power supply inlet of the cooler (fig. 3: 1).
• Connect the connection cable to the 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.

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

Battery monitor mode	LOW	MED	HIGH
Switch-off voltage at 12 V	10.1 V	11.4 V	11.8 V
Restart voltage at 12 V	11.1 V	12.2 V	12.6 V
Switch-off voltage at 24 V	21.5 V	24.1 V	24.6 V
Restart voltage at 24 V	23.0 V	25.3 V	26.2 V

This is how to select the battery monitor mode:

• Switch on the cooler.
• Press the “SET” button (fig. 2: 4) three times.
• Use the “UP +” (fig.2: 6) and “DOWN -” (fig.2: 7) buttons to select the battery monitor mode.
• The selected mode then appears in the display for a few seconds. The display flashes several times before it returns to the current temperature.

Setting the temperature

• Press the “SET” button (fig. 2: 4) once.
• Use the “UP +” (fig.2: 6) and “DOWN -” (fig.2: 7) 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.

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 cover slightly open. This prevents odour build-up.

Defrosting the cooler

Humidity can form frost in the interior of the cooling device or on the vaporiser. This reduces the cooling capacity. Defrost the device in good time to avoid this.

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 cover open.
• Wipe off the defrosted water.

Replacing the AC fuse

WARNING! Danger of electrocution!

Disconnect the connection cable before you replace the device fuse.

• Pull off the connection cable.
• Pry out the fuse insert (fig. 3: 2) with a screwdriver.
• Replace the defective fuse with a new of the same type and rating (T2.5AL 250 V).
• Press the fuse insert back into the housing.

Replacing the DC plug fuse

• Pull the adapter sleeve (fig.6: 4) off of the plug.
• Unscrew the screw (fig.6: 5) out of the upper half of the housing (fig.6: 1).
• Carefully raise the upper half of the housing from the lower (fig.6: 6) half.
• Take out the contact pin (fig.6: 3).
• Replace the defective fuse (fig.6: 2) with a new fuse of the same type and rating (3AG, Fast Acting, 8 A).
• Re-assemble the plug in the reverse order.

Replacing the light bulb

• Press the switch pin (fig.7: 2) downwards so that the transparent part (fig.7: 1) of the lamp can be removed at the front.
• Replace the light bulb.
• Press the transparent part of the lamp back into the housing.
