Product Q&A

Ask Us a Question
  • How often do I need to service my Dometic RV/Caravan appliances?

    Dometic recommend servicing their gas appliances on a yearly basis, even if the vehicle has not been used. Additionally, bear in mind that insects can built nests in the gas appliances which will cause the appliances to stop working. It can also cause potentially dangerous scenarios.

    For other appliances, such as refrigerators and air conditioners, to ensure the appliances to work efficiently and last longer it is recommended to clean the condenser.

  • How do I deactivate the child-lock in my RUA/RUC model refrigerator?

    These models have a great lock for children to prevent any accidental adjustments. You know that you have activated the child-lock if you are unable to change the temperature or the power source. You can either permanently deactivate or temporarily override the lock - please see below:

    • Temporarily Override the Child-lock:
    • Push the control knob 3 times within 1.5 seconds
    • The lock will be reactive again after 10 seconds without touching the control knob
    • Permanently Deactivate the Child-lock:
    • Start with doing a temporarily override, after that simply turn off the child lock in the settings menu
  • My vehicle has a battery management system, will that cause a problem?

    Battery management systems switch off the power supply to the refrigerator as soon as the vehicle engine is switched off for longer than 30 minutes. The refrigerator requires a constant DC power supply to operate. If your vehicle has a battery management system, just be aware that it may switch of the DC power to the fridge. Dometic recommend deactivating the battery management system.

  • When should I defrost the refrigerator?

    Defrost your refrigerator as soon as a layer of ice forms in the freezer compartment. The freezer compartment will require periodic manual defrosting, recommended if the frost layer is higher than 3 mm.

  • When you say the product is 75W @ 240V, won't it also be 75W at 12V just with a higher current draw (310mA Vs 6.25A? So this leads me to a further Q: is the 75W the power consumption when the compressor is running (max consumption) or is it an average? Th

    Hi Bill,

    The ratings are supplied by Dometic in their tech specs for this refrigerator.

    The 75W would be an average. 

    The rated current at 12V is 10.5A.

    Power consumption at ambient temperature of 32 °C, +3 °C refrigerator: 3.0Ah/h @ 12V

  • Will the fridge work of a generator ( not an inverter type )Regards Maurice

    Hi Maurice

    The fridge is able to be powered by a generator as it can run on 240v.

    However, I would recommend an AVR or inverter generator to regulate clean power to fridge.

    Kind Regards

  • What vents on the side of the van are needed for this type of fridge (compressor)? Some research suggests none are needed other than a maybe a top vent. Other sites say standard upper and lower vents plus maybe a top vent.

    Hi There,

    Dometic recommend the use of a top and bottom vent. This allows cool air to enter the van from below, and remove the hot air from above allowing the compressor to work as efficiently as possible.

  • What is the average amp draw per hour on this fridge please?

    Hi There,

    Please find the average power consumption below:

    Avg Power Consumption - 3.0 Ah/h (12V)

  • What wattage is this unit please

    Hi There,

    The wattage of this fridge on 240V is 75 W

  • If the refrigerator has an automatic cyclic defrost system, why is manual defrosting still needed?

    If the refrigerator is used for extended periods in high humidity and/or high ambient temperature conditions, frost may build up on the evaporator fins behind the internal fan cover, which can reduce the cooling performance. In this case a manual defrost is recommended. The freezer compartment will require periodic manual defrosting, recommended if the frost layer is higher than 3 mm.

  • Can I store heavy objects such as bottles or cans anywhere on the refrigerator?

    Only store heavy objects such as bottles or cans in the refrigerator door, in the vegetable compartment or on the bottom shelf.

  • Does it have a security feature to prevent accidental adjustments?

    The device has a child lock feature to prevent accidental adjustments or children from using the controls.

  • The refrigerator is suitable for use with what voltage?

    The device is designed to be operated from a 12 V DC or 24 V DC on-board supply as well as from a 100 – 240 V AC mains.

  • Where can the Refrigerator be installed?

    The device is suitable for installation into caravans, motorhomes or boats. The refrigerator is only suitable for installation in a fitted cavity. Once it is installed, only the front of the appliance may be accessible.

  • Can the fridge be inclined?

    The refrigerator can withstand a short-term inclination of 30°, for example on boats.

  • Does it have protection against reversed polarity and short circuit?

    The refrigerator is equipped with an electronic system to prevent the polarity being reversed. This protects the refrigerator against reversed polarity when connecting to a battery and against short circuiting.

  • Can the device be installed in an open area?

    The refrigerator must be installed in a recess so that it stands secure when the vehicle is in motion. It is recommended to install the refrigerator in a sealed location in order to prevent dust and heat from entering the living space of the caravan or motorhome.

  • What is the cooling capacity of the device?

    The RUc fridge can refrigerate goods between 0 °C and +8 °C. The freezing temperature range is between –20 °C to –10 °C.

  • Can I use extension power cables or power strips with the device?

    To avoid voltage drops and loss of performance, keep the connection cable as short as possible and uninterrupted. Therefore, avoid additional switches, plugs or power strips.

  • What is the door airing function used for?

    Use the door airing function if you do not intend to use the refrigerator for a prolonged period of time. This prevents mould from forming when the refrigerator is not in use or put into storage.

  • The refrigerator has a mild odour, is this normal?

    When using the refrigerator for the first time, there may be a mild odour which will disappear after a few hours. Air the living space well.

  • Does it have an indicator when something is wrong with it?

    Yes. On the display, if there is an active error indication, the backlight and screen will not turn off. The display enters error screen. In the error screen, the middle section is highlighted in red and shows the relevant error code.
