Fast Delivery. Easy to install.

WAECO CoolMatic CRX 140

By: 14 December 2017

Its been a week now since I installed of the fridge and I have to say I am one happy customer. It started with totally unexpected support and service from Grace on the phone, Then utterly terrific delivery (actually arrive a day early). Since installation, I have been impressed with the frugal power usage. Installation was a cinch with just connection of 2 wires and plugging into my vans 240v outlet. I have 450watts on the roof and a 225 ah Lithium battery

  • 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. 

  • What do I need to think about in regards of the ventilation with my Dometic compressor fridge?

    Dometic Compressor fridges work best when there is air flowing across the compressor.

    For small to medium sized Dometic fridges (CRX50, CRX80 & CRX110), minimum of one vent is required. This should be mounted in the van wall, parallel to the compressor at the top of the fridge. Vent options are:

    For the CRX140 is a little different, the fridge compressor is mounted on the top of the fridge. It is best to only use one vent mounted at the top rear of the fridge. Install the fridge in a way that you can pull air from the front, up the side of the fridge over the compressor and out the vent.

    The compressors above 140 Litre, (RUC6408X & RUC8408X), these large sized fridges require two vents, one at the bottom and one at the top. In this case it would be best to choose the 2 x LS300 vents.

  • What do I need to know about installing my 12v compressor fridge in my van?

    Installation instructions will come with your 12V Compressor Fridge. The installation/manual document will also cover:

    • Recommended ventilation  
    • Side and rear gap sizes for installing in your RV cavity
    • Mounting
    • Wiring

    Depending on the model, there will also be information regarding; maintenance, cleaning, defrosting, energy saving tips, reversible doors, inserting new door panels and troubleshooting.

  • Does the fridge auto select between 12v/24v?

    Hi - Yes it does!

  • Do you need to disconnect the battery if connecting to 240v mains supply?

    Hi there - No you don't, 240v takes priority.
