RM7XX5 L - models are equipped with an “AUTO”-MATIC function.
1. Set energy selection switch (A) to position
“AUTO” .
The LED "AUTO" illuminates.
Manual operation is possible at any time.
Explanations:
Upon switching on, the electronics automatically select one of the three
possible energy types: 230V - 12V - liquid gas. The control electronics
automatically ensure that the refrigerator is supplied with the optimum
source of energy in each respective case.
Priority
1.) Solar (12V DC)
2.) 230V AC
3.) 12V DC
4.) Liquid gas
The selected energy is displayed by the corresponding LED (i.e. 230V).
230 V - operation
If sufficient supply voltage is available (more than 200V), this power source is
selected as the first option ( no solar-system installed).
12 V - operation
12V operation should only be selected while the vehicle motor is running or there
is sufficient voltage available from the solar system. This can be detected from
the D+ connection of the alternator to the electronics, or from the respective signal on the solar charge regulator.
Gas operation
Gas operation is selected in the following circumstances:
Ÿ No supply voltage available.
Ÿ The vehicle engine is not running.
Ÿ Supply voltage less than 200V
REFUELLING STOP
In order to prevent unintended switching to gas operation during refuelling,
the electronic system starts gas operation of the refrigerator, after the
motor has been turned off for 15 mins. During this time the appliance is in
stand-by operation mode and only the "AUTO" LED lights up.
The use of naked flames is prohibited in petrol station environments.
If the refuelling stop lasts longer than 15 mins., the refrigerator should be
switched off at the main switch (A), or switched over to another energy
type.

INSTALLATION GUIDE
On installation of the appliance, the technical and administrative regulations of the
country in which the vehicle will first be used must be adhered to. Otherwise the
refrigerator must be installed as described in these instructions. In some OEM applications it may not be possible for these instructions to be followed exactly. In this case
an authorised Dometic representative may issue supplementary instruction
In Europe, for example, gas appliances, cable laying, installation of gas
cylinders, as well as approval and checking for leaks must comply with
EN 1949 for liquid gas units in vehicles.
6.1
Installation
The appliance and its fume extraction shall be installed in such a way as to be accessible for servicing at all times and must be capable of easy removal and installation.
The appliance may only be installed by authorised personnel.
Installation and connection of the appliance must comply with the latest
technical regulations, as follows:
Ÿ The electrical installation must comply with national regulations.
Ÿ Technical regulationsEN 60335-1, EN 60335-2-24, EN 1648-1 , EN 1648-2
Ÿ The gas installation must comply with national regulations.
Ÿ Technical regulations EN 1949
Ÿ Technical regulations EN 732
Ÿ Local and building control department requirements
Ÿ The appliance shall be installed in such a way that it is shielded from
excessive heat radiation.
Excessive heat impairs performance and raises the energy consumption of the
refrigerator.
Any installation that is not carried out by qualified persons will jeopardize the manufacturer's guarantee.
6.1.1
Side installation
If the appliance is installed on the same side of the vehicle as the entrance
door, it is desirable that the door does not cover the refrigerator’s vents.

the vents.
6.1.2
Rear installation
If the refrigerator is mounted at the rear of the vehicle you must ensure the lower grille
is not covered by the bumper or rear lights.
This would be prevent the air from circulating properly and cause problems in
warm weather.
Air vent grille not
blocked: OK!
19
6.2
Draught-free installation
The refrigerator must be sealed in accordance with EN 1949.
Illustrated below are two typical approved methods of sealing.
Proposal 1:
FIG. 1
Using the Installation Sealing Kit from Dometic

the refrigerator !
In addition, discharge plate (B) with its lipped seal
(A) must seal the refrigerator off from the living area
(see FIG. 1).
Ensure that the refrigerator is installed level in the
recess.
Proposal 2:
Another option is to provide the refrigerator with a cowl
(A). The cowl (A) should ideally be affixed to the caravan
wall, not to the refrigerator. Insert sealing strips at the
bottom and sides of the cover.
Finally, push the refrigerator into the cover from the front.
Both of these installation options facilitate the removal and installation of the appliance for servicing.
Comment:
Other methods of sealing may be approved. However the
chosen method must prevent draughts entering the living space of the motorhome.
Failure to seal correctly will allow warm air to collect around the refrigerator and its
performance will be affected.
If the cavity between the caravan wall and the refrigerator is sealed so that fumes
cannot penetrate the living area it is possible to vent the flue gas directly through the
upper grille without using the aluminium flue pipe. For this installation method, it is
recommended that the same air vent grille should be used at the top and at the
bottom (L200), and that the T-piece of the flue pipe is turned 45 degrees.
20
In this case, for gas operation, do not use the upper winter covering!
If even with draught-free installation a fume chimney is desirable, you must incorporte the L100 ventilation and extraction system into the upper air vent opening.
Installation of fume chimney: please refer to point 6.7.
Deviations shall require the consent
of the manufacturer.
6.3
Ventilation and extraction
A correct installation is important for correct operation of the appliance to ensure,
there is no build-up of heat at the back of the appliance. This heat must be allowed
to escape into the open air.
In the event of high ambient temperatures, full performance of the cooling unit
can only be achieved by means of adequate ventilation and extraction.
15-20mm
without step
15-20mm
with step
Ventilation is provided for the unit by means of two apertures in the caravan wall.
Fresh air enters at the bottom, extracts the heat and exits through the upper vent
grille.
The upper ventilation grille should be positioned as high as possible above
condenser (A).
The lower ventilation grille should be flush with the floor of the vehicle, allowing
any gas leakages (heavier than air) to escape directly into the open air.
If such an arrangement is not possible a hole must be provided under the refrigerator
(not close to the burner) so that any leaking LP gas can escape. This must have an
effictive area of at least 13cm². It is desirable to fit the hole with wire mesh or similar,
and an angle plate to protect it from stones, mud etc., the wire mesh must not reduce
the effective area of 13cm² (EN1949).
The ventilation grilles must have an open cross-section of at least 250 cm2.
This is reached using the Dometic Absorber Ventilation and Air Extraction
System L100 / L 200 that has been tested and approved for this purpose.
Comment:
If the distance between the wall and the refrigerator is greater than 20 mm the gap
can be reduced to 20 mm by fitting a suitable baffle piece.
Correct mounting of the lower ventilation grille facilitates the access to
the electrical and gas connections during maintenance work.

6.5
Installation recess
The refrigerator must be installed draught-free in a recess.
The measurements of the recess are given in the table below.
Step (A) is only required for cabinets with a step. Push the appliance far enough into
the recess until the front edge of the refrigerator casing is flush with the front of the
recess. Allow a gap of 15-20 mm between the back wall of the recess and the
refrigeration unit. The floor of the recess must be level, allowing the appliance to be
pushed easily into its correct position. The floor must be substantial enough to bear the
weight of the appliance.
Ensure that the refrigerator is installed level in the recess.

In the sidewalls of the refrigerator, there are four plastic
sleeves with screws for securing the refrigerator. The
sidewalls or rails attached for securing the refrigerator
must be designed in such a way that the screws will
remain firmly in place even when under increased load
(while the vehicle is moving).
Always insert screws through the sleeves provided;
otherwise, structural parts embedded in the foam,
such as cables, etc., may be damaged.
Once the refrigerator is in its final position, secure the
screws into the wall of the recess.
The screws must penetrate through the sheet metal
casing of the refrigerator.

Fume extraction
Fume extraction must be arranged in such a way as to provide complete
extraction of all products of combustion to an area outside the living area.
The flue system must slope in an upward direction in order to avoid a
build-up of condensation.
An installation that is not carried out by qualified persons causes a
reduction in the cooling capacity and will jeopardize the manufacturer's guarantee.

Electrical installation
Electrical installation may only be carried out by qualified personnel.
The connection cables must be laid in such a way that they do not come
in contact with hot components of the unit/burner or with sharp edges.
The electrical installation must comply with national regulations
(EN 60335-2-24, EN 1648-1, EN 1648-2 for Europe).
It is advisable to run the incoming supply through an on-board fuse or
automatic circuit breaker. The power cable must be laid in such a way
that it does not come in contact with hot components of the unit/burner
or with sharp edges.
Changes at the internal electrical installation or the connection of other
electrical components (e.g. additional fan) to the internal wiring of the
appliance will expire the e1/ CE admittance as well as any claims from
guarantee and product liability!
6.9.1
Power line connection
The power must be supplied via a properly earthed socket outlet or hardwired connection.
Where a socket outlet is used for the mains connection lead, the outlet
must be freely accessible.
It is advisable to run the incoming supply through an on-board fuse or automatic
circuit breaker.
The power cable must be laid in such a way that it does not come in contact with hot
components of the unit/burner or with sharp edges.
If the connection cable is damaged it must be replaced by the Customer
Service at Dometic, or by respectively qualified personnel, in order to
prevent any hazards.
6.9.2
Battery connection
The machine's mains 12V connection cable is connected (observing correct
polarity) to a terminal strip. The cabling must be direct and by the shortest possible
route to the battery and alternator respectively.
Cross-sectional area of cable
Length of cable
4mm²
< 6m
6mm²

The 12V circuit must be protected with a 16A fuse.
The heating element circuit must be connected to the vehicle battery by a suitable
ignition operated relay in order that the 12V supply is only live while the vehicle
ignition is switched on.
The connection C/D (interior light, electronics ; cable black / violet)
must be permanently attached, and must not be cut-out when the vehicle
ignition key is turned off.
This can be realised with an on-board habitation battery i.e.
If the appliance is installed in a caravan the respective leads for 12V+
and 12V- the connections A/B and C/D must not be connected to each
other on the caravan-side ( EN 1648-1).
