DC connection, To mount the door panel with screws

Installation instructions

12 V DC connection

The connection is made to the terminal block marked

“12 volts DC heater”, located at the bottom left corner on the back of the refrigerator cabinet.

The refrigerator must be connected to the battery circuit with two wires of adequate capacity to avoid voltage drop. The wire gauge should be chosen with consideration to the wire length in accordance with the table below.

Maximum conductor wire length

Wire length	Min. wire size

5 m	4 mm2
8 m	6 mm2

To ensure safe operation, the positive lead must be fitted with a fuse rated at 20 amps. Correct polarity must be observed when connecting to the 12 V DC supply. DO NOT use the chassis or vehicle frame as one of the conductors. Connect

CHANGING DOOR SWING

The refrigerator is equipped with a reversible door. A special door reversing kit must be used to reverse the door. For fur- ther information, please contact your dealer.

MOUNTING THE DOOR PANEL

The refrigerator is normally delivered without door panel Before starting the mounting work, read this instruction thor- oughly and check that the panel dimensions are in compli- ance with those given in the following table:

Panel dimensions

Max thickness 4 mm

		Height			Width
RM2453	827		825	527		524
RM2553	983		981	527		524

two wires at the refrigerator and route to the 12 V DC sup- ply. The refrigerator will draw 15 amps at 12 volt DC.

The connections must be clean, tight and free from corrosion. If not, a resulting voltage drop will cause a decreased cooling capacity.

Note! DO NOT operate the refrigerator on 12 V when the vehicle is parked. The amperage draw of the 12 V DC heat- ing element can discharge a battery in a very short time. The installation of a 12 V DC operated refrigerator requires a relay to be installed on the tow vehicle or in the caravan. The relay will automatically shut off the 12 V DC power to the refrigerator when the ignition is turned off.

One of the standout features of the RM2453 is its innovative absorption cooling technology. Unlike traditional compressors, which can be noisy and consume a lot of energy, the RM2453 operates silently and requires minimal power. This is particularly beneficial for RV and marine applications, where noise reduction and energy efficiency are paramount. The refrigerator uses a unique ammonia-based cooling system, which is not only efficient but also environmentally friendly. This ensures that users can enjoy a consistent temperature without the disturbance of compressor noise or the drawbacks of refrigerants that may harm the environment.

The Dometic RM2453 is equipped with a three-way power source, allowing it to operate on AC, DC, and propane. This versatility means that users can easily switch between power sources depending on their needs and availability, ensuring that the refrigerator remains operational regardless of their location. Whether plugged into a campsite electrical hookup, running off the vehicle’s battery, or utilizing propane while boondocking, the RM2453 provides flexibility that many other refrigerators cannot match.

Another notable characteristic of the RM2453 is its user-friendly design. It features adjustable shelving, allowing users to customize the internal configuration to accommodate various sizes of food items and containers. The reversible door hinge offers greater flexibility in terms of installation and access, ensuring that the refrigerator can fit seamlessly into any space.

In terms of build quality, the Dometic RM2453 is designed for durability. Its robust construction is engineered to withstand the rigors of travel and the marine environment. With a sleek and modern aesthetic, it not only performs exceptionally but also enhances the overall look of the kitchen or galley it occupies.

Overall, the Dometic RM2453 stands out in the market for its combination of energy efficiency, versatility, and practical design. It remains a top choice for those seeking a reliable refrigerator solution for their mobile lifestyle, delivering excellent performance and convenience in a compact package.
