Key Components of the Dometic RV Refrigerator
The Dometic RV refrigerator features essential components like the manual gas valve, electrical controls, ignition system, and flue baffles, ensuring efficient operation in both gas and electric modes.
Gas and Electric Operation Modes
The Dometic RV refrigerator operates in two modes: gas and electric. Gas mode is ideal for off-grid use, utilizing LP propane for cooling, while electric mode is suitable for campsites with power hookups. The refrigerator automatically switches between modes based on the available power source, ensuring continuous operation. For gas mode, the ignition process involves lighting the flame, which is monitored by the igniter. The manual gas valve must be turned on, and the electronic control ensures the flame is maintained. In electric mode, the unit relies on a 12V DC power supply or 120V AC, depending on the setup. Both modes are designed for efficiency and safety, with features like pressure regulators and leak detection to prevent hazards. Proper operation in either mode requires adherence to the manual’s guidelines to maintain performance and safety standards.
Manual Gas Valve and Its Function
The manual gas valve on the Dometic RV refrigerator controls the flow of LP propane to the burner. Located at the rear, it must be turned on for gas mode operation. The valve is equipped with a 3/8 SAE male flare connection, ensuring a secure link to the gas supply line. Before use, connections should be checked for leaks using soapy water. The valve plays a critical role in safety, allowing users to shut off gas supply immediately if needed. Proper operation of the manual gas valve is essential for efficient cooling and to prevent potential hazards, such as gas leaks or ignition issues. Always refer to the manual for specific instructions on valve operation and maintenance.
Electrical Connections and Controls
The Dometic RV refrigerator’s electrical connections and controls are essential for its operation in electric mode. Located at the rear, these components are accessible through the lower vent in the vehicle’s exterior wall. A continuous 12V DC power supply is required for the electronic control system, which manages both gas and electric functions. The igniter, operating on 12V DC, plays a crucial role in igniting the gas flame during gas mode. Proper electrical connections ensure safe and efficient performance. Users must avoid touching electrical switches if gas is detected and ensure all connections are secure to prevent issues. Regular checks of these components are vital for maintaining reliability and safety in both operational modes.
Installation and Setup Instructions
Preparation involves disconnecting power and capping leads. Connect gas supply, ensuring no leaks. Follow safety guidelines for electrical and gas hookups to ensure proper installation.
Preparation for Installation
Preparation is crucial for a safe and successful installation. Begin by disconnecting the 120V AC power cord and capping the 12V DC leads if applicable. Turn off the LP gas supply and ensure the area is well-ventilated. Open RV windows and doors to prevent gas accumulation. Locate the manual gas valve at the rear of the refrigerator and ensure it is turned off. Check for any existing connections or obstructions that may interfere with the installation. Review the manual thoroughly to understand all safety precautions and requirements. Ensure all tools and materials are ready, including a pressure regulator and leak detection supplies. Proper preparation ensures compliance with safety standards and a smooth installation process.
Connecting the Gas Supply Line
Connecting the gas supply line to your Dometic RV refrigerator requires careful attention to safety and proper technique. The gas supply line attaches to the manual gas valve, which features a 3/8 SAE (UNF 5/8-18) male flare connection. Ensure the connection is secure and leak-free by using soapy water to test for any escaping gas. The system must include a pressure regulator to maintain a supply pressure of 11 inches water gage. Refer to the manual for specific instructions on connecting the line and testing for leaks. Always follow local gas codes and safety guidelines to ensure a safe installation. Proper connection is critical for efficient and safe operation of the refrigerator in gas mode.
Electrical Hookup and Safety Precautions
When connecting your Dometic RV refrigerator to an electrical power source, ensure the connection is safe and meets all specifications. Disconnect the 120 VAC power cord from the receptacle at the rear of the refrigerator enclosure before starting any installation. If applicable, disconnect and cap the 12 VDC leads to prevent accidental power supply. Avoid using electrical switches or sparking devices if you smell gas, as this could ignite the gas. Ensure proper ventilation in the RV to prevent gas buildup. Always use a Ground Fault Circuit Interrupter (GFCI) protected outlet for the 120 VAC connection. Follow all local electrical codes, such as CSA Z240.4 for gas-equipped recreational vehicles, to ensure a safe and compliant installation.
Operating the Dometic RV Refrigerator
