Evakool Indel B 31 40 50 AC/DC Compressor Portable Fridge / Freezer – Operation Manual

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

• Your unit requires good ventilation, especially around the back of the refrigerator; allow a gap of at least 100mm around all sides.
• 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.
• 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.
• It is recommended to operate the unit on a flat surface, but it will operate at angles up to 30°.

3. Operation

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.

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).

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:

AC minimum wire dimension: 0.75mm² or 18AWG

Control Panel Operation

Diagram of the control panel: Features include an LED Display, Temperature Controls (with UP and DOWN buttons), an ECO/MAX SWITCH, and an ON/OFF SWITCH. Indicator lights for ECO MODE LED and MAX MODE LED are also shown.

Temperature setting range: -30°C to 40°C

The LED Display range: -40°C to 45°C

• Press the [Up Arrow] or [Down Arrow] button to adjust the temperature the unit aims to achieve. Press the [Up Arrow] button to increase or the [Down Arrow] button to decrease the temperature.
• When you press the [Up Arrow] and [Down Arrow] buttons at the same time, it switches the display between °C and °F.
• Press the button “ECO” to enter the economy running mode; the ECO indicator green LED light will be on. Press the button again; the unit will enter the maximum running mode, the MAX indicator red LED light will be on.
• The economy mode runs the compressor at a lower speed to save power; the maximum mode runs the compressor at a higher speed increasing power usage. Maximum mode is useful if the ambient temperature is over 30°C or fast cooling is required.
• Plug in the DC or AC power. Press the ON/OFF button to turn the unit on. The LED display on the control panel will turn on and the interior temperature is displayed.
• If the power supply is cut off or disconnected, the unit will switch off automatically and once the power supply is restored it will automatically switch back on.

4. Cleaning and Maintenance

• Clean the appliance inside and out with a clean damp cloth every week. If it is dirty, use sodium bicarbonate dissolved in lukewarm water to clean the unit.
• Never use abrasive products, detergents or soap. After cleaning, wipe out with a clean damp cloth and dry carefully.
• Do not store product inside unit if the unit is not on.
• Do not store the unit if it is wet inside or without leaving the lid open.
• Never clean the unit under running water or in dish water. Do not use abrasive cleaning agents or hard objects during cleaning as these can damage the unit.

Illustration depicting cleaning precautions: Various cleaning items such as bottles, a pot, and a sponge are shown on a striped surface, marked with red 'X' symbols, indicating that abrasive products, detergents, or harsh objects should not be used for cleaning.

5. Troubleshooting

The unit is not turning on

• Check whether the unit has been turned on.
• Check the power supply (try a different power source, i.e. different vehicle or power socket).
• Check whether the plug and the socket have a good connection.
• Check whether the fuse has been burned out or blown.

Low refrigeration performance

• Too much product been placed inside the unit.
• There is too much warm product inside the unit.
• The lid is unlatched / or open.
• The lid seal is broken.
• Problems arising from poor ventilation (ensure at least 100mm of space around all sides).
• The ambient is too high.
• The temperature setting is too high.

Can hear the sound of running water from inside the unit

This is normal, due to the flow of refrigerant in the unit.

Unusual noise when refrigerator is working

The refrigerator is not placed on a level surface.

If none of the above solves your issue please contact Evakool or your local Evakool service centre.

6. Security Certificate

Certifications include SAA, CE, and CCC.
