4.0 Installation instructions

The unit and the exhaust duct system must be

in principle installed so that it is accessible for

maintenance work, can be easily installed and

dismantled and removed from the vehicle wit-

hout great effort.

Installation and connection of the appliance

must comply with the latest technical regulati-

ons, as follows:

 The electrical installation must comply

with national and local regulations.

 The gas installation must comply with

national and local regulations.

 European Standards EN 1949

 European Standards EN 60335-1,

EN 60335-2-24, EN 1648-1 , EN 1648-2

 The appliance must be installed in such

a way that it is shielded from excessive

heat radiation.

Excessive heat impairs performance and rai-

ses the energy consumption of the refrigera-

tor!

4.1 Installation

Deviations from these installation instructi-

ons without prior notification of Dometic

result in Dometic GmbH's warranty obliga-

tions becoming void!

The appliance may be installed by autho-

rised personnel only!

WARNING!

(Fig. 4 )The air vent grilles offer an unobstruc-

ted dissipation of heat and exhaust gas even

when the door is opened.

4.1.1 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. (Fig. 3, Clearance door/ventilation grille

at least 25 mm). Otherwise ventilation could

be impaired which causes a loss in cooling

performance. Awnings are often placed at the

door side of a caravan. This complicates eva-

cuation of combustion gases and heat through

the ventilation grilles (loss in cooling perfor-

mance)!

(Fig. 3) The air vent grilles are blocked. There

must be a distance between the door and the

air vents of at least 25 mm!

If the door/grille distance is between 25 mm

and 45 mm, we recommend installing a

Dometic ventilation kit

(item no. 241 2985 -

00/0)

to achieve an optimal cooling perfor-

mance in high ambient temperatures.

Installation

Another unfavourable method of rear installa-

tion is to install the air intake and exhaust gril-

les (Fig. 6) at the side wall of the recreation

vehicle. The air-heat recirculation is very

restricted which means that heat exchangers

(condenser, absorber) cannot be adequately

cooled. The optional method of an additional

air vent grille installed in the floor also exhibits

an insufficient air flow duct.

Fig. 5

Air vent grille

not blocked!

OK!

4.1.2 Rear installation

Rear installation often causes an unfavourable

installation arrangement, as ideal ventilation

cannot always be assured (e.g. the lower ven-

tilation grille is covered by the bumper or the

rear lights of the vehicle!). The maximum coo-

ling performance of the aggregate is actually

not available.

The maximum cooling performance is not

available! Do not apply this installation

method, as it does not provide proper ven-

tilation! Please refer to the description in

section 4.2.

CAUTION!

Fig. 6

4.1.3 Draught-proof installation

Refrigerators in motorhomes, caravans or

other vehicles must be installed in a draught-

proof manner (EN 1949). This means that the

combustion air for the burner is not taken from

the living space and that exhaust fumes are

prevented from entering the living space.

Adequate sealing between the back of the

refrigerator and the vehicle interior has to be

provided.

Dometic strongly recommend using a flexible

sealing for this purpose (temperature-resi-

stant up to 200 °C in the area of the oven),

in order to facilitate future removal or installati-

on of the appliance during maintenance

By no means use durable sealing com-

pounds, fitting foam or similar material to

realise draught-proof installation of the

refrigerator ! Do NOT use any easily

inflammable materials for sealing (in parti-

cular silicon sealing compound or similar).

Risk of fire! The device manufacturer's

product liability and warranty shall lapse if

such materials are used.

WARNING!

The lip seals (1) are installed at the bottom and

on each side in the installation recess (Fig. 7-

9). A heat deflector plate (2) is installed in the

installation recess above the refrigerator. Affix

Attach the deflector plate so that the heated

air escapes through the top ventilation grill into

the open air and no heat build-up can be pro-

duced.

The refrigerator is later pushed into the instal-

lation recess from the front. Ensure that the

seals abut the case evenly.

This installation option facilitates the removal

and installation of the appliance for servicing.

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. The

waste gases escape to the outside through

the upper grill of the ventilation. Do not use

any kind of aluminium flue pipe to lead the flue

gas out.

Fasten the sealing lips to a stop bar on the

rear side (1), e.g. by gluing.

The refrigerator must be installed draught-

proof in a recess (also refer to Section "4.1.3").

The measurements of the recess are stated in

the table below. Push the appliance far

enough into the recess until the front edge of

the refrigerator casing is aligned with the front

of the recess. Allow a gap of 20 mm bet-

ween the back wall of the recess and the refri-

geration 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. Install a removable screen / grill

above the oven (for fixing and removing of flue

outlet).

Ensure that the refrigerator is installed level

in the recess.

Installation

Fig. 17

In the event of high ambient temperatures,

full performance of the cooling unit can

only be achieved by means of adequate

ventilation and extraction.

A correct installation of the refrigerator is

essential for its correct operation, as due to

physical reasons heat builds up at the back of

the appliance which must be allowed to esca-

pe into the open air.

If ventilation and exhaust duct into the vehicle

is intended, fresh air supply must not be

obstructed. The room in which the device is

installed must have one or several openings

allowing fresh air to enter (safety ventilation

according to EN 721). These openings must

have a total cross section of at least 100

cm². There must be one or several ventila-

tion openings above the device with mini-

mum cross sections of 150 cm². These have

to be checked and if necessary cleaned regu-

larly. Roof and wall outlet openings can be

combined. Lower ventilation openings must

be no more than 100 mm above the inside

floor. The ventilation openings must by no

means be shut. Grilles and covers must be

kept clean and free of dust.

(for ventilation to the vehicle’s interior)

Ventilation is provided for the unit by means of

two apertures (ventilation grilles) in the cara-

van wall. Fresh air enters at the bottom,

extracts the heat and exits through the upper

vent grille (chimney effect). The upper venti-

lation grille should be positioned as high as

possible above the cooling unit (Fig. 11).

Install the lower ventilation grille at floor

level of the recess floor (Fig. 16), allowing

unburnt gas (heavier than air) to escape direct-

ly into the open air. The gas burner must be

located above the edge (1) ..

Should this arrangement prove impossible,

a ventilation aperture must be introduced

by the manufacturer of the vehicle into the

recess floor in order to avoid the accumula-

tion of unburnt gas on the floor.

The ventilation grilles must have an open

cross-section of at least 400 cm². This is

achieved by using the Dometic LS 300 absor-

ber ventilation and air extraction system

which has been tested and approved for this

purpose.

Installation

Special cowls for mounting on the roof are

used for the ventilation and exhaust gas duct.

Only use the cowl and pipes specified in

these instructions. These are tested and

approved for the application.

CAUTION!

There must not be any materials not desi-

gned for temperatures over 120 °C in the

vicinity of cowl and exhaust gas pipe.

CAUTION!

The hot exhaust air escapes from inside the

oven through the ventilation slots in the front

panel.

4.4.2 Truma roof cowl AK3 installation

A round cutout with diameter 60 mm is made

in the vehicle roof for the installation of the

Truma roof cowl. The roof cowl is bolted in the

roof cutout. The flexible stainless steel flue

pipe is pushed into the roof cowl and onto the

spout of the exhaust gas outlet (1) and fixed

with a worm drive clamp or the bolts supplied

by Truma to the roof cowl.

The exhaust gas duct must slope upward.

The minimum installation height of the flue

pipe between top edge of the unit and exhaust

gas outlet at the cowl must not be less than

250 mm. A maximum of 1500 mm is possible.

A clearance of at least 50 mm from surroun-

ding walls and components must be maintai-

ned.

system

4.4.1 Installing LS300

To install the ventilation grilles, cut two rectan-

gles width b = 490mm, height a= 249mm, in

the outer wall of the vehicle (for position of the

cuts, see Fig.11).

289 0318-40_EN_RMDT85xx-Installation_N1.qxp 20.08.2012 12:32 Seite 16

The exhaust gas duct system must be made in

such a manner as to achieve a complete

extraction of combustion products to the out-

side of living space. The flue gas is vented

directly through the upper grille. Do not use

any kind of aluminium flue pipe to lead the flue

gas out.

The T-piece (Fig. 28) must be aligned with the

exterior wall.

EAn installation other than described will

reduce the cooling capacity and jeopardi-

se the manufacturer's warranty/product

liability.

CAUTION!

Installation

4.5 Exhaust duct system

(refrigerator)

After the refrigerator is put in its final place,

secure the screws into the wall of the recess.

The screws must penetrate the casing of the

refrigerator.

Fig. 29

Fig. 27

In the sidewalls of the refrigerator, there are

four plastic sleeves for securing the refrigera-

tor. The sidewalls or strips attached for secu-

ring the refrigerator must be prepared to hold

the screws firmly in place even when under

increased load (while the vehicle is moving).

Fastening screws and caps are supplied with

the refrigerator.

4.6 Securing the refrigerator

Always insert screws through the sleeves

provided as otherwise components laid in

foam, such as cables etc., could be dama-

ged.
