he refrigerator can be run on either 230 V, 12 V or LP gas.

C

hanging between these modes of operation is carried out

b

y means of the controls of the control paner shown in fig 3.

T

he voltage selector (A) can be set at either 230 V,

1

2Vor0.

R

efrigerator temperature is controlled by a thermostat (B)

w

hen the unit runs on 230 V.

T

he gas supply is turned on/off by means of the knob (C). It

a

lso serves to select one of three different gas inputs.

T

he refrigerator is fitted with a safety device which auto-

m

atically shuts off the supply of gas if the flame goes out.

T

he safety device can be opened manually by depressing

c

ontrol (C).

T

he piezoelectric igniter discharges a spark over the burner

w

hen the button (D) is depressed.

urner. A blue light can be seen through it when the flame

i

s alight.

S

TARTING THE REFRIGERATOR

T

he position numbers refer to fig. 3.

L

P Gas operation

A

fter initial installation, after servicing, changing gas cylin-

d

ers etc.,the gas lines may contain some air which should

b

e allowed to escape by briefly turning on the refrigerator or

o

ther appliances. This will ensure that the flame lights

i

mmediately.

B

efore you start gas operation:

1

. Open the shut-off valve of the gas bottle (check that there

is enough gas). Open any on-board shut-off valve.

2

. Check that the switches for mains and 12 V operation are

off.

3

. Turn the gas control (C) to position MAX.

4

. Depress the knob (C) of the flame failure device and hold

it down while depressing the piezoelectric igniter button

(D) several times in quick succession.

5

. Check the flame indicator/sight glass that the flame is

alight.

6

. Keep the knob (C) depressed for a further 10-15 sec.

7

. Release the knob and again check that the flame stays

alight.

T

o terminate gas operation, turn knob (C) to ●.

2

30 V Operation

1

. Turn off the gas by means of the shut-off valve.

2

. Set the voltage selector (A) to 230 V.

3

. Turn the electric thermostat (B) to the highest (coldest)

position.

1

2 V Operation

O

nly operate your refrigerator on 12 V when the engine of

t

he vehicle is running - otherwise your battery will soon be

d

ischarged.

● If applicable, turn off the gas operation

● Depress the voltage selector (A) to position 12 V.

W

INTER OPERATION

P

lease check that the ventilation grilles or the flue outlet are

n

ot blocked by snow, leaves, etc.

DOMETIC ventilation grilles A 1620 (fig. 11), can be

f

itted with winter covers, modell WA 120, to protect the

c

ooling unit against cold air. The covers may be fitted when

t

he outside temperature is below approx. 10° C and should

b

e fitted when the temperature is below freezing point.

W

e suggest that you fit the winter covers also in the case

t

hat the vehicle is laid up during the winter season.

R

EGULATING THE TEMPERATURE

T

he position number refers to fig. 3.

O

nce the refrigerator has been started it will take a few

h

ours to become cold.

O

n 230 V operation the refrigerator is controlled by a ther-

m

ostat and the thermostat knob (B) should be set at 3-5. If

a

lower (colder) temperature is desired, set the thermostat

t

o a higher figure.

O

n 12 V operation the refrigerator works continuously.

L

P gas operation should always be initiated with the knob

(

C) at the max position. If the ambient temperature is above

2

5° C and/ or the door of the refrigerator is frequently ope-

n

ed the knob should be left at that position. Below 25° C the

k

nob should be set at mid and below 10° C at min to avoid

t

emperature below freezing in the main compartment.

T

RAVEL CATCH

M

ake sure that the travel catch is engaged when the cara-

v

an is on the move.

T

he travel catch at the top of the door can be set in two

d

ifferent positions. In one position the door is held tightly

s

hut. In the other position the door is secured ajar so that

t

he refrigerator can be aired when not in use.

F

OOD STORAGE

A

lways keep food in closed containers. Never put hot food

i

n the refrigerator; allow it to cool first.

N

EVER KEEP ITEMS IN THE REFRIGERATOR WHICH

M

IGHT GIVE OFF FLAMMABLE GASES.

T

he 2-star (✱✱) frozen food compartment is intended for the

s

torage of frozen food and for making ice. It is not suit-able

f

or freezing items of food.

N

ever put bottles or cans of fizzy drinks in the frozen food

s

torage compartment as they may burst when freezing. Also

d

on't give children ice lollies straight from the compartment

a

s they could cause frost burns.

Caution!

Only use one source of energy at a time

8

M

ost kinds of frozen food can be stored in the frozen food

c

ompartment for about a month. This period of time may

v

ary, however, and it is important to follow the instructions

o

n the individual packings.

I

CE-MAKING

F

ill the ice tray just below the brim with drinking water and

p

ut the tray on the freezer shelf.

I

t is possible to make ice faster by turning the control knob

t

emporarily to its highest value but do not forget to turn it

b

ack to its regular setting afterwards as the refrigerator

m

ight otherwise become too cold.

D

EFROSTING

F

rost will gradually accumulate on the refrigerating sur-

f

aces. It must not be allowed to grow too thick as it acts as

a

n insulator and adversely affects refrigerator performance.

C

heck the formation of frost regularly every week and when

i

t is about 3 mm thick it will be necessary to defrost the

r

efrigerator.

T

o defrost the refrigerator, turn it off and remove the ice tray

a

nd all food items. Normally the temperature of items of

f

ozen foods would rise unduly during defrosting and so they

s

hould be consumed within 24 h or discarded.

D

o not try to accelerate defrosting by using any kind of

h

eating appliance as the plastic surfaces of the refrigerator

m

ight then be damaged. Neither should any sharp objects

b

e used to scrape off the ice.

T

he defrost water runs from a collector channel down a

t

ube to a drip tray at the rear of the refrigerator where it

e

vaporates. When all the ice has melted, wipe the refrigera-

t

or dry and restart it.

P

lace the food items back inside but wait until the refri-

g

erator is cold before making ice cubes.

C

LEANING THE REFRIGERATOR

C

lean the inside of the refrigerator regularly to keep it fresh

a

nd hygienic.

S

oak a cloth in a solution consisting of a teaspoon of bicar-

b

onate of soda to half a litre of warm water. Wring out the

c

loth and use it to clean the interior of the refrigerator and

i

ts fittings.

N

ever use detergents, scouring powder, strongly scented

p

roducts or wax polish to clean the interior of the refrigera-

t

or as they may damage the surfaces and leave a strong

o

dour.

T

he exterior of the refrigerator should be wiped clean now

a

nd again, using a damp cloth and a small quantity of deter-

g

ent. But not the door gasket, which should only be cleaned

w

ith soap and water and then thoroughly dried.

T

he cooling unit behind the refrigerator should be cleaned

w

ith a brush from time to time, but make sure that the

r

efrigerator is switched off when doing this.

T

URNING OFF THE REFRIGERATOR

I

f the refrigerator is not to be used for some time:

● Shut off any on-board valve in the gas line to the refrige-

rator.

● Set the voltage selector (A), fig. 3, to 0.

● Set the gas valve (C) to ●.

● Empty the refrigerator. Defrost and clean it as described

earlier. Leave the doors of the refrigerator and the frozen

food compartment ajar. Use the travel catch to hold in

this position.

I

F THE `FRIDGE FAILS TO WORK

C

6

. If the refrigerator fails to work on 230 V, check:

● That the 230 V supply is connected to the refrigerator.

● That the fuse is intact.

I

f the refrigerator is not cold enough it may be because:

1

. The ventilation is inadequate owing to reduced area of the

ventilation passages (partial blockage of grilles from wire

mesh etc).

2

. The evaporator is frosted up.

3

. The temperature control setting is incorrect.

4

. The gas pressure is incorrect - check the pressure regula-

tor at the gas container.

5

. The ambient temperature is too high.

6

. To much food is loaded at the same time.

7

. The door is not properly closed or the magnetic sealig

strip is defective.

8

. More than one source of energy is used at the same time.

I

f the refrigerator still does not work properly, call a service

t

echnician.

● Fit the trim moulding back in place.

I

NSTALLATION/BUILDING-IN

I

nstallation in open air applications.

(

Under an awning, on a veranda, etc.)

● Place the refrigerator protected from rain, direct sun

exposure and strong draught.

● The location should be cool and with good air circulation

to avoid concentration of the flue gases. The ventilation

opening at the top of the refrigerator must not be co-

vered.

● Place the refrigerator on a sturdy base so that it does not

tipp over when its door is opened.

● The base must be level. Check with a water level and

adjust if necessary.

I

nstallation indoors

T

he room should have a capacity (lenght x width x height)

o

f at least 20 m

3

and have a window (wich can be opened)

o

r a door to the outside.

I

t is important that the refrigerator is not subject to heat

r

adiation from a stove etc.

10

F

or best performance also at high ambient temperatures

t

here must be a free air circulation over the cooling unit at

t

he rear of the refrigerator.

T

he refrigerator is designed for a free-standing installation

a

nd the clearance to side walls etc., should be at least

5

cm (2'').

I

f the refrigerator is to be built-in, openings with sufficient

a

rea must be foreseen for the access and exit of air for the

c

ooling unit, as shown in fig. 2. The letters in the figure refer

t

o:

F Access for cooling air

G Exit for air (upwards)

H Exit forwards (alternative)

I

nstallation in a caravan or motorhome

T

he refrigerator must be installed in a recess (fig. 2) with

t

he dimensions given in TECHNICAL DATA.

T

he refrigerating unit is ventilated via two openings in the

w

all of the caravan. The opening must be fitted with suitable

g

rilles, to give a free cross-section of at least 250 cm

2

.

G

rilles specially developed for this application can be obtai-

n

ed from DOMETIC (model A 1620).

F

our fasteners are fitted in the plastic bushings in the side

w

alls of the fridge, fig. 4. They are used for securing the

r

efrigerator in the enclosure.

T

he side walls of the enclosure and/ or any wooden braces

i

nstalled to fix the refrigerator must be dimensioned to seat

t

he screws securely, also considering the forces due to the

m

ovement of the vehicle.

W

ith the refrigerator in place, drive the screws through the

b

ushings in the lining of the refrigerator into the walls of the

e

nclosure. There must not be more than 3mm of clearance

b

etween refrigerator and enclosure on each side. If neces-

s

ary, wooden strips or similar should be fitted.

N

ote: This is the only approved means of securing the

r

efrigerator to the enclosure and to the vehicle. Fasteners

p

enetrating other parts of the insulation (PU) foam of the

r

efrigerator might damage components like electric wiring

e

tc.

F

lue gas must be exhausted through a flue extension, to be

o

rdered separately or purchased through our service organi-

s

ation,

T

he distance between the flue tube and combustible

m

aterial must not be less than 20 mm at any point. The

s

pace around the tube where it passes through the caravan

w

all should be packed with glass wool protected with

s

uitable metal plates. Install the flue extension as shown in

f

ig. 5.

T

he upper DOMETIC grille has an integrated flue

o

utlet, fig. 7. In this case the traditional flue outlet, is not

n

eeded which simplifies the installation.

I

f there is no outer grille at floor level where leaking gas can

e

scape, a 40 mm hole should be made in the floor of the

r

ecess to drain the gas. The hole should be fitted with wire

m

esh and an angled plate to protect it from stones, mud

e

tc.

L

P GAS CONNECTION

T

he refrigerator is designed for operation on liquified petro-

l

eum gas (LPG), the pressure of which must be:

● for Butane type LPG 28 mbar

● for Propane type LPG 37 mbar

C

heck that this is stated on the data plate.

T

he refrigerator is not designed for operation on town gas or

n

atural gas.

T

he gas equipment is shown in fig. 6. In the burner (P) is a

t

hermocouple (O), which generates an electric current

t

hrought the flame failure device (N), keeping it open as

l

ong as the flame burns. The valve (M) opens/closes the

g

as mechanically. It also has a ``MIN'' position for cold

w

eather. The piezo igniter (L) is connected to the spark plug

(

Q). The gas connecting tube (K) has a nipple (J) with left

h

and thread R 1/4.

.

.. in open air applications

F

or this application a hose connection to the LPG-bottle is

u

sed. Only use rubber hose with crimped on connectors

a

pproved for LPG.

A

pressure regulator (as described above) is assembled to

t

he LPG-bottle. Check that the rubber gasket in the shut off

v

alve of the bottle is clean and undamaged, as also the

s

ealing surface in the pressure regulator. The nut should

o

nly be thightened by hand - otherwise the gasket might be

d

amaged.

T

he connection is made as follows (figs. 6/9):

● Put the refrigerator on its side

● Connect hose to nipple (J) and thigten by hand. (Note:

left hand thread!).

● Thigten carefully with a wrench, thereby holding the

nipple (J) with second wrench.

● In the same way, connect other end of hose to pressure

regulator on LPG bottle.

● Open shut off valve of bottle, putting the hose under

pressure.

● Check for leaks at the connections, using water with

detergent, watching for bubbles. If leaking: carefully

thigten with two wrenches as explained above until

formation of bubbles stops.

● In similar way check also thigtness between nipple (J)

and tube (K) and thighten if necessary.

● Also check connection between pressure regulator and

LPG bottle. If leaking, clean sealing surfaces and inspect

for damage. If found defective: exchange (return LPG

bottle), but do not use any foreign sealing compound.

C

AUTION: If there are still leaks, call in a service

technician.
