The Dometic FreshJet FJZ4 1700 is a roof-mounted air conditioner with electronic controls, designed for caravans, motorhomes, and campervans up to 6 metres in length. It provides 1700W of cooling capacity and 800W of heating through its fixed-speed compressor, making it a genuine year-round climate control solution. Available in white or black (the black finish applies to the rooftop unit only), this unit weighs 28.4 kg and measures 752 x 225 x 702 mm. It fits a standard 400 x 400 mm roof opening with roof thicknesses between 25 mm and 60 mm. Running on 220-240V AC, it draws 3.4A for cooling and 3.5A for heating, with a minimum circuit protection requirement of 4A.
How does the Dometic FJZ4 1700 differ from the FJZ4 1500?
The FJZ4 1700 steps up from the 1500 with electronic controls, Wi-Fi connectivity, an 800W integrated heating function, and built-in CleanAir air purification. It covers vehicles up to 6 metres (versus 5.5m for the 1500) and uses the more environmentally friendly R32 refrigerant with a GWP of 675, compared to R410a (GWP 2088) in the 1500 model.
The FJZ4 1700 comes with Wi-Fi connectivity built in, allowing you to control and monitor your climate remotely through the Dometic smartphone app. The integrated CleanAir bipolar ioniser system is a standard feature on this model, actively reducing bacteria, mould build-up, and unpleasant odours inside your vehicle. The air distribution box (FJZ ADBD, sold separately) features an electronic touch control display with integrated warm white LED ambient lighting, vertically adjustable outlet vents, and a low-profile design standing at 48 mm high. Airflow is rated at 318 m³/h, distributed in two directions (front and back). The reusable dust filter lifts out for easy cleaning. This model uses R32 refrigerant (320g charge) with a global warming potential of 675, a significant environmental improvement over the R410a used in the entry-level FJZ4 1500.
For vehicle owners who regularly travel to warmer European destinations, the FJZ4 1700 is sized for caravans and motorhomes up to 6 metres. The heating function provides 800W of warmth, useful for cooler evenings in spring and autumn. Dometic backs this unit with a 5-year warranty on parts, and it operates across an ambient temperature range of -2°C to +52°C. The operating temperature range of -2°C to +52°C means you get heating performance down to near-freezing conditions.

3 years warranty when fitted at the Dometic Fitting Centre
We have partnered with Dometic to offer you an
extra years warranty. If you buy the fitted option above you will take your vehicle to the Dometic Fitting Centre in Tewsbury. The price paid here includes the
standard fitting and it will be fitted directly by Dometic themselves. As Dometic are fitting the air conditioning unit, they are happy to offer 3 years warranty instead of 2! You will also have the piece of mind that the fitting of the unit will be first-class as it will be fitted by a dedicated team of Dometic Service Engineers.
What happens once I place the fitted order with us?Once you place the order with us, we will send your details to the Dometic Fitting Centre. A Dometic team member will then contact you to organise a convenient time for you to bring in your vehicle. Be advised that Dometic will require a photograph of the roof of your vehicle as well as an interior image of the roof light and the surrounding area so they are able to assess if any additional work will be required to fit the unit. We will request this by email after you place the order with us. Please ignore the shipping information. We will not ship the FJX41500 to you, it will be delivered to the fitting centre in Tewkesbury awaiting your vehicle.
Standard fitting involves the removal of an existing 400 by 400 roof light and replacing with, and wiring in, the roof-top unit and installation of the ADB inside the interior of the vehicle. The cost does not include the moving or any other rooftop items you might have e.g. solar panels. If it is found that additional work is required the Dometic Fitting Centre will advise accordingly.
