This manual provides essential instructions for the installation and connection of the Dometic 10-Series refrigerator (RML 10.4, RML 10.4S, RML 10.4T). Proper installation is critical for safety and performance.
Safety instructions
- Explosion hazard: Never open the absorber unit; it is under high pressure. Use only the gas pressure specified on the type plate.
- Fire hazard: Use only propane or butane gas. Do not use naked flames to check for leaks. Ensure clean handling of sealants.
- Health hazard: Do not operate if visibly damaged. Repairs must be performed by qualified personnel.
- Asphyxiation: When disposing of the old device, remove doors and leave shelves inside to prevent accidental enclosure.
Installation
The refrigerator must be installed in a draft-proof location in caravans or motor homes.
Preparing the installation
- The vehicle must be parked horizontally (max 3° angle).
- Maintain a minimum distance of 5 mm from the floor to allow the door to open.
- Ensure no heat-sensitive components (cables, ducts) are near the gas burner.
Draft-proof installation
To prevent combustion air from being extracted from the interior, use a flexible seal between the rear panel and the vehicle interior. Three versions are available (Fig. 8):
- Stop bar (A): Glue a flexible sealing lip to a stop bar behind the refrigerator.
- Side gap up to 5 mm (B): Glue sealing lips to the side of the furniture.
- Side gap 5-10 mm (C): Glue double-lipped sealing to the side of the furniture.
Ventilation
- Install air inlet and outlet vents in the outer wall.
- Distance between inlet and outlet vents must be at least 1050 mm.
- If the minimum distance cannot be met, install a roof vent.
- Use original Dometic ventilation grills (LS230 or LS330).
Connecting the refrigerator
Gas supply
- Connection must be performed by a specialist.
- Use a metal-sealed screw connection.
- Always use a backup wrench (17 mm) when connecting the gas supply line.
- Perform a leak test and flame test after installation.
DC and AC power
- DC power: Connect to the battery. The electronics use the D+ signal to detect the running engine. Protect the heating element supply line with a 20 A fuse and the electronics supply line with a 2 A fuse.
- AC power: Connect using the device plug. Do not cut off the plug.

Common problems
Poor cooling performance
Check ventilation (ensure min 1050mm distance between vents), check rear wall distance (15-25mm), and ensure no heat-sensitive components are near the burner.
Gas smell or leak
Switch off the device, avoid flames/sparks, air the room well, and contact an authorized specialist.
Condensation inside the refrigerator
Check door seal, ensure food is not stored while too warm, and ensure the condensation drain has a constant slope.
Before use
- Ensure the vehicle is parked horizontally (max 3° angle).
- Verify gas type (propane/butane) and pressure match the type plate.
- Ensure ventilation grills are original Dometic parts.
- Check that the power supply voltage matches the type plate.
- Ensure the installation is draft-proof.
