Installing the refrigerator 6 Installing the refrigerator 6.1 Preparing the installation RMDX21, RMDX25 When installing the refrigerator, note the following: To enable the refrigerant to circulate properly, the refrigerator may not exceed an angle of 3° from level. To achieve this, park the vehicle on a level firm surface. Ensure the refrigerator is level.
RMDX21, RMDX25 Installing the refrigerator If the minimum distance between the air inlet and outlet vents cannot be met, a roof vent must be installed instead of the air outlet vent. – The roof vent should be installed directly above the back of the refrigerator as far as this is possible. Use an air duct (fig. 5 1, page 4) if you need to install the roof vent offset, otherwise heat will accumulate there. – The distance between the air inlet vent and the roof vent must be at least 1400 mm (fig.
Installing the refrigerator 6.2 RMDX21, RMDX25 Installing the refrigerator in a sealed location separate to the living space Gas-powered refrigerators in caravans or motorhomes must be installed in a sealed location. This means that the combustion air can not be extracted from the interior and exhaust fumes are prevented from directly entering the living space. A suitable seal must be provided and fitted between the rear wall of the refrigerator cabinet and the interior of the vehicle.
RMDX21, RMDX25 Installing the refrigerator 6.3 Making air inlet and outlet vents I NOTE At high ambient temperatures, the refrigerator can only provide its maximum cooling capacity if the optimum ventilation has been provided. ➤ Make a cut out in the wall to fit an appropriate upper and lower vent system, choose LS300 check the dimensions required for the vent. See chapter “Preparing the installation” on page 22.
Installing the refrigerator 6.4 RMDX21, RMDX25 Installing the ventilation grille No. in fig. 9, page 5 Description 1 Slider 2 Ventilation grille 3 Installation frame ➤ Ensure the installation frame is water resistant (fig. 0, page 5). ➤ Insert the installation frame and screw it down tightly (fig. a, page 5). Use all the fixing holes for this. ➤ Fit the ventilation grille (fig. b, page 6). ➤ Insert the slider and lock the ventilation grille with it (fig. b, page 6). 6.
RMDX21, RMDX25 Installing the refrigerator 6.6 Installing the flue duct I NOTE Do not install an additional flue stack, as this leads to poor performance and increases the power consumption of the refrigerator. Mount the flue duct under the upper ventilation grille (fig. g 1, page 7). Install the flue duct as follows: ➤ Make a rectangular opening in the outer wall of the vehicle (fig. h, page 7). – The opening must be as wide as the flue pipe (fig. g 3, page 7).

This refrigerator may only be connected to the gas supply by a specialist in accordance with the applicable guidelines and standards. Only use cylinders of universal LPG gas fitted with an approved gas pressure regulator. Compare the pressure information on the data plate with the pressure information on the pressure regulator on the gas cylinder.
RMDX21, RMDX25 Connecting the refrigerator 7.2 Connecting to DC and AC A NOTICE! The electrical installation and repairs may only be performed by a specialist in accordance with the applicable regulations and standards. The respective negative and positive cables of the DC connections for heating and controls may not be joined with one another in a caravan. This can cause electrical interference or damage to electrical components.
Connecting the refrigerator RMDX21, RMDX25 ➤ Connect the refrigerator as follows (fig.
RMDX21, RMDX25 Connecting the refrigerator AC power ➤ Connect the refrigerator with the mains plug to an AC socket. DC power Please note the following cable sizes: – < 6 m (interior): 6 mm2 – > 6 m (interior): 10 mm2 – Connections D+ and S+: 1 mm2 ➤ Protect the DC power supply for heater with 20 A fuse and use a minimum of 6 mm low voltage cable. ➤ Protect the DC power supply for controls with 2 A fuse and use a minimum of 1 mm low voltage cable.
Connecting the refrigerator RMDX21, RMDX25 S+ (RMDX25 only) In automatic mode, the refrigerator is first powered with DC power from the vehicle's own solar system. The refrigerator electronics uses the S+ signal of the solar charge controller to detect a solar system. The solar charge controller must have an AES output and produce sufficient current to run the refrigerator. ➤ Connect the S+ connection on the controller (fig. t G, page 14) to the respective terminal of the solar charge controller.
RMDX21, RMDX25 Technical data See fig. y, page 17 Using a fridge movement switch to add 12 Vg to the D+ connection wire, only when the vehicle is moving. The Anderson plug connection must keep the house battery fully charged. House battery recharged by vehicle. The D+ is turned on and off via an optional fridge movement switch. See fig. z, page 17 Anderson plug recharging the house battery via a power diode. The D+ wire can only get a 12 V signal when the battery is being charged.
