5. PREPARE FOR INSTALLATION

WARNING

FIRE OR EXPLOSION HAZARD. Failure to obey the following warnings could result in serious injury or death:

• Turn off LP gas supply at the tank.
• Never use an open flame to check for gas leaks.

5.1 Removing the existing refrigerator

Proceed to “5.2 Preparing the refrigerator enclosure” if a refrigerator is not already present.

➤➤ Unplug the 120 VAC power cord from the receptacle at the rear of the refrigerator enclosure.
➤➤ Disconnect the 12 VDC leads from the refrigerator and cap the lead ends.
➤➤ Turn off the LP gas supply to the refrigerator.
➤➤ Disconnect the LP gas line from the refrigerator.  Cap the line and verify there are no LP gas leaks
➤➤ Remove the screws anchoring the refrigerator to the enclosure.
➤➤ Slide the refrigerator out of the enclosure and remove it from the RV.

5.2 Preparing the refrigerator enclosure

Inspecting the refrigerator enclosure

➤➤ Verify the following to inspect the refrigerator enclosure:

• There are no holes, other than ventilation holes, inside the enclosure.
• The surface for sealing strips is clean and flat to allow a complete seal.
• No objects are protruding into the enclosure, except utility connections for the refrigerator.
• The enclosure seams are sealed to prevent flue gases from leaking into the living area.
• Utility hookups are present and comply with all applicable codes.

Assembling the refrigerator enclosure

➤➤ Ensure the following when assembling the refrigerator enclosure:

• The refrigerator must be level and installed in a sturdy enclosure.
• The floor must be level and able to support the weight of the refrigerator and its contents.
• Adjacent heat sources must not affect the ventilation of the refrigerator.
• All joints in the enclosure must be sealed to prevent flue gases from leaking into the living area.
• The enclosure must be free of materials that may damage the refrigerator.
• A wood strip must be placed above the upper opening of the enclosure. The top frame of the refrigerator is anchored to the wood strip with screws.
• The refrigerator must not be installed directly on carpeting.

5.3 Choosing the type of vent application

Read before proceeding:

• Certified installation requires one lower fresh air intake vent and one upper exhaust vent.
• Center the vents to the back of the refrigerator. Refer to “Offset vent application” if it is not possible to center the vent.
• Use only the Dometic vents specified for the installation.
• Ensure that vent openings are clear of obstructions.
• Ensure that the lower vent opening is even with, or below, floor level to allow any raw LP gas to escape.
• Do not allow the floor to block or interfere with the vent openings.
• Additional holes are required for vents installed above floor level to vent raw LP gas outdoors. The holes must be a diameter of 1-3/4″, clear of any obstruction, and covered with a screen (minimum 14 X 14 per inch).

Roof vent application

• This application is recommended for typical installations.
• This application can be used if the vents are inboard or offset due to a radius roof or interference with building materials.

➤➤ Check the enclosure depth and add a baffle, if required.

Upper and lower side vent application

• Choose this type of installation when a roof vent installation is not possible.
• A baffle should be added.
• The refrigerator must be equipped with fan(s).

Island application

• This application is intended for refrigerators installed on an inside wall and must be vented through the floor to the ceiling.

Corner application

• This application is intended for refrigerators installed in the rear corner of the vehicle or in an angled cabinet.
• The refrigerator must be equipped with fan(s).

Offset vent application

• The vents must always be offset toward the flue side of the cooling unit.
• For offset vent applications, prior written approval and safety certification must be obtained from Dometic Corporation.

5.4 Installing the vent application

WARNING ; FIRE OR EXPLOSION HAZARD. Make sure vent allows raw (unburned) LP Gas to escape to the outside. LP Gas is heavier than air, and will collect at floor level if not vented correctly. Failure to obey this warning
could result in death or serious injury.

Read before proceeding:

• Use the inboard installation option when the radius of the roof, or the presence of building materials, interferes with the placement of the roof vent.
• All fasteners are to be provided by the installer.
• Select the appropriate screw types for the application for which they are being used.
• Minimize screw lengths to fit applications appropriately, unless otherwise noted.
• Rivets are acceptable only where noted.

➤➤ Apply sealant around the thread or rivet body of all fasteners.
➤➤ Apply dry sealant around the surface mounting face of all vent frames or vent bases before installation.
➤➤ Apply wet sealant around the perimeter of all vent frames or vent bases after installation. Do not allow the sealant to block the molded weep tracks in the vent frame.

• Do not allow insulation to come into contact with the cooling unit.

➤➤ Cut the insulation two to three inches shorter than the depth of the enclosure.
➤➤ Secure the insulation to the enclosure walls and ceiling. This will prevent it from shifting when the refrigerator is installed.

5.7 Connecting the water supply

For refrigerator models equipped with ice maker, ice and water dispensers:

➤➤ Ensure that the water supply system has a minimum pressure of 15 pounds per square-inch (psig).
➤➤ Use a 1/4″ diameter water line to the water valve at the rear of the refrigerator.
➤➤ Ensure that the water line is equipped with a manual shut-off valve that is easily accessible.

6. INSTALLATION

6.1 Installing the refrigerator

Refrigerator model RM1350SL is equipped with vacuum-insulated panel technology. The insulating panels are located on the top, back, sides, and doors. If the surface is punctured, the effectiveness of the insulation will be reduced, resulting in poor refrigerator performance.

6.5 Connecting the gas

WARNING : FIRE OR EXPLOSION HAZARD. Failure to obey the following warnings could result in property damage, serious injury, or death:

• Install gas connections in compliance with the applicable supplemental directives listed in this manual. Refer to”1.3 Supplemental directives” on page 3.
• Never use an open flame to check for gas leaks. Use a commercial leak detection solution to check all connections, as specified in these instructions.
• Should the gas supply fail to shut off or if overheating occurs, shut off the gas valve to the refrigerator before shutting off the electrical supply.
• Do not put sealing compound on flair fittings.
• Never use a wire or pin to clear obstructions from burner jet (damage will occur).
• Do not attempt to adjust burner jet.

Read before proceeding:

• Connection to the gas supply line is accomplished at the manual gas valve. The manual gas valve is furnished with a 3/8″ SAE (UNF 5/8″ -18) male flare connection.

• The gas supply system must incorporate a pressure regulator to maintain a supply pressure of not more than 11″ water column.

• When testing the gas supply system at test pressures:
  –– greater than 1/2 psi, the refrigerator and its individual shutoff valve must be disconnected from the gas supply piping system.
  –– 1/2 psi, or less, the refrigerator must be isolated from the gas supply piping system by closing the individual manual shutoff valve.

• If local codes allow for the use of a flexible gas appliance connector, do not use a connector that has previously serviced another gas appliance.

• If detailed instructions on the installation and connection to the gas supply are required, contact the nearest dealer or distributor.

➤➤ Always use two wrenches to hold the valve and flair nut when loosening and tightening gas connections.
➤➤ Route all connections to avoid contact with the boiler casing, burner cover, or any other refrigerator components.
➤➤ Perform an air pressure test on the piping system.
➤➤ Examine all completed connections for leaks using a commercially available soap solution made for the detection of leaks.
