This document provides visual installation instructions for the Dometic RTX 1000 and RTX 2000 air conditioning units. The installation process relies on specific roof cutout dimensions and precise bolt length calculations based on the thickness of the vehicle roof. Ensure you have the correct mounting kit and tools before beginning.
Roof cutout and preparation
The unit requires a specific roof opening to be prepared. The standard cutout dimensions are 500mm by 400mm. Ensure the roof surface is clean and level before proceeding with the installation. Verify that the surrounding area allows for the specified clearances (at least 100mm on sides) to ensure proper airflow.
Sealing and mounting
Proper sealing is critical to prevent leaks. Apply the seal to the unit base according to the thickness of the roof (t). Use the provided mounting hardware to secure the unit to the roof. Tighten the mounting bolts to the specified torque settings: 10Nm for the primary bolts and 8Nm for the secondary securing points. Do not overtighten.
Bolt length calculation
The length of the mounting bolts (L1, L2, L3) must be calculated based on the thickness of the roof (x). Use the following formulas provided in the manual to determine the correct bolt length for your specific vehicle:
- L1 = x + 5...9mm
- L2 = x + 23...27mm
- L3 = x + 9mm
Electrical connection
The unit is designed for 12V systems. The electrical connection must be made as close to the power source as possible, with a maximum cable length of 0.3 meters to ensure optimal performance and safety. Ensure all connections are secure and protected from moisture.

Common problems
Incorrect bolt length
Calculate L1, L2, and L3 based on your specific roof thickness (x) using the formulas provided in the manual.
Leaking seal
Ensure the roof surface is clean and the seal is applied evenly before mounting the unit.
Before use
- Verify roof thickness (x) to calculate correct bolt lengths.
- Ensure the roof cutout is exactly 500x400mm.
- Check that the electrical connection is within 0.3m of the power source.
- Use a torque wrench to tighten bolts to 10Nm and 8Nm.
- Ensure at least 100mm clearance around the unit on the roof.
