The Dometic FreshJet FJZ7 3000 is a high-capacity inverter roof air conditioner delivering 3000W of cooling and 3000W of heating for caravans and motorhomes up to 9 metres in length. This is where the FJZ7 range steps up in physical size: the rooftop unit measures 1090 x 240 x 700 mm, larger than the 752 x 225 x 702 mm footprint of the FJZ7 2200 and 2600 models, though it still fits the same standard 400 x 400 mm roof opening with roof thicknesses of 25 to 60 mm. Available in white or black, it weighs 35.8 kg. Current draw is 6.4A for cooling and 5.9A for heating, requiring a minimum circuit protection of 7A. It runs on 220-240V AC at 50Hz.
How much cooling power does a 9-metre motorhome need?
Dometic recommends the FJZ7 3000 for vehicles up to 9 metres, providing 3000W of cooling and 3000W of heat pump heating. The inverter compressor adjusts output to demand, drawing 6.4A for cooling with 7A circuit protection. At 35.8 kg and 1090 x 240 x 700 mm, it's the larger-format rooftop unit in the FJZ7 series.
The FJZ7 3000 includes all premium FJZ7 features. Adaptive Power Mode lets you cap the maximum power consumption through the Dometic smartphone app to suit your campsite's available amperage. Advanced Sleep Mode holds the inverter compressor at a constant low frequency for quiet overnight operation. The SmartECO function enables off-grid use when paired with a Dometic TEMPRA lithium battery (300 Ah minimum recommended) and a compatible inverter. Wi-Fi connectivity comes built in for remote climate monitoring and control. CleanAir bipolar ioniser technology is fitted as standard, reducing bacteria, mould, and odours. The air distribution box (FJZ ADBD, sold separately) provides electronic touch controls, warm white LED lighting, adjustable outlet vents, and 350 m³/h airflow.
The 3000W heat pump output matches the cooling capacity watt-for-watt, making the FJZ7 3000 a strong choice for owners who tour from early spring through to late autumn and want consistent cabin warmth without relying solely on gas heating. The unit uses R32 refrigerant (480g charge) with a global warming potential of 675, and operates across an ambient temperature range of -2°C to +52°C. The aerodynamic rooftop profile features Dometic's signature LED light curve. Dometic provides a 5-year warranty on parts across the entire FJZ7 range.

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.

Frequently Asked Questions
Yes. The FJZ7 3000 measures 1090 x 240 x 700 mm, which is significantly wider and slightly taller than the FJZ7 2200 and 2600 (both 752 x 225 x 702 mm). It still fits the same standard 400 x 400 mm roof opening, but you'll need to check you have sufficient clear roof space around the cut-out for the larger external unit.
The FJZ7 3000 weighs 35.8 kg for the rooftop unit. The compatible FJZ ADBD electronic air distribution box (sold separately) adds a further 3.9 kg. The total installed weight is approximately 39.7 kg. Check with your vehicle manufacturer that your roof can support this load before installation.
The FJZ7 3000 requires a minimum circuit protection of 7A. Its Adaptive Power Mode lets you set a maximum power draw via the Dometic app, so if your campsite provides less than 7A, you can limit the unit's consumption to match. The inverter compressor's smooth start-up avoids the current spikes common with fixed-speed models.
Yes. The FJZ7 3000 delivers 3000W for both cooling and heating. The heating is provided by energy-efficient heat pump technology, which reverses the refrigeration cycle to warm the cabin. This balanced output makes it a strong all-season climate control solution for larger motorhomes and caravans.
The FJZ7 3000 uses R32 refrigerant with a charge of 480g. R32 has a global warming potential (GWP) of 675, which is lower than the R410a refrigerant (GWP 2088) used in some older and smaller Dometic models. The R32 refrigerant contributes to the FJZ7 range's improved environmental profile.
