Frequently Asked Questions - CS-24 Ravanson

How does the Ravanson CS-24 work?

The CS-24 uses a Peltier cell (semiconductor) to cool or heat the interior. When powered via 12V DC, it can cool the contents to about 12–15°C below ambient temperature or warm them for short periods.

Can I use it as a refrigerator at home?

No, the CS-24 is designed for short‑term portable use (e.g., in a car) and is not a substitute for a domestic refrigerator. It only maintains a temperature difference relative to the environment.

What temperature can I expect in cooling mode?

In ideal conditions, the interior will be 12–15°C cooler than the surrounding air, with a minimum achievable temperature of about +8°C. Actual performance depends on ambient temperature, load, and ventilation.

How do I switch between cooling and heating?

First, turn the device off using the power or function switch. Open the lid for about 30 minutes to let the interior reach room temperature, then select the desired mode (COLD or HOT) with the function switch and turn the device back on.

Can I plug it into a wall outlet?

The CS-24 model (CS‑24S) is designed for 12V DC only (vehicle lighter port). Do not connect it to a standard 220–240V AC wall outlet, as that could damage the device. Other models like CS‑24S SUPER are compatible with both 12V DC and 230V AC.

How should I clean the cooler?

Disconnect the power first. Use a slightly damp, soft cloth with a mild detergent to wipe the inside and outside. Never use harsh solvents, petrol, or alcohol, and never submerge the device in water.

Why is my cooler not cooling?

Check that the power switch is set to DC and the function switch is in COLD mode. Ensure the 12V lighter socket is working and the fuse in the plug is intact. Verify that ventilation holes are not blocked and the unit has free airflow.

How long can I run the cooler continuously?

The manual recommends a maximum of 6 days of continuous operation. After that, switch it off for at least 2 hours to allow the aluminum radiator to defrost and prevent frost buildup.

Is it safe to leave it on overnight?

Yes, as long as the unit is placed on a stable surface with adequate ventilation and the power cord is undamaged. However, do not cover the cooler or block its ventilation holes to avoid overheating.

Can I put ice or liquids inside the cooler?

No, do not fill the interior with ice, water, or any liquid directly. The device is designed for solid food and packaged drinks only. Moisture can damage the electronics.

NOTE!

The manufacturer is not liable for the use does not conform to specifications, or improper handling.

II. INTENDED USE

The device is designated for short-term storage of food cooled in the domestic refrigerator and for cooling drinks. The cooling system is based on the semi-conducting Peltier cells without the compressor and coolant.

ATTENTION!

The de9ice is not designated for cooling warm or hot food!

NOTE!

The fridge cools food products to about 12 - 15°C below ambient temperature. The device is not a substitute of a domestic refrigerator.

The cooling temperature depends on multiple factors, e.g. ambient temperature, quantity of cooled products, products' temperature.

In favourable conditions, temperature decrease by 12 - 15°C below the ambient temperature may take place in about 2 hours of continuous operation. (min + 8°C)

ATTENTION!

The fridge with a heating f+nction is not designated for heating prod+cts. It can be +sed solely for extending the cool-down time for prod+cts pre-heated in designated de9ices.

IV. GENERAL GUIDELINES FOR USE

NOTE!

Before first use, clean the inside of the appliance by wiping with a slightly wet (not wet) cloth with mild detergent.

1. The fridge is not designated for continuous operation. Frost can accumulate on the aluminium radiator. Switch the fridge off after 6-day operating period. The device can be switched on again after 2 hours.

2. To prevent condensation, dry the surface of cooled meals and drinks thoroughly.

3. During operation (ref. 12V supply) ensure there is no recurring voltage interruption when the vehicle engine is switched on and off frequently.

ATTENTION!

When the fridge is powered by means of a vehicle battery, during stops it can discharge it significantly which can hinder vehicle engine activation.

NOTE!

Temperature change in the insulated fridge container (frequent opening or switching off) leads to natural phenomena in the form of frost or condensation on the container walls, on the cover inside and on the food products.

V. OPERATION

Place the refrigerator on a stable and level surface. Connect the power cord to the power source. The fridge will start cooling or heating the internal chamber immediately.

ATTENTION!

After reach]n[ the m]n]m+m/max]m+m tem(erat+re the de9]ce does not t+rn off a+tomat]cally.

The cool]n[ system o(erates cont)n+o+sly when ]t ]s connected to the (ower so+rce and the f+nct]on and (ower sw)tches are ]n the work mode.

ADVICES TO ACHIEVE THE BEST COOLING PERFORMANCE:
