s connected to the threaded nipple (J) of fig. 6. Its other
e
nd is connected to the reducing valve of the gas bottle as
s
hown in 8 ig. 9 or to an easily accessible gas shut off valve
w
hich forms a part of the fixed gas installation of the buil-

.. in vehicles
T
he gas supply pipe should be connected to the gas inlet
p
ipe on the right hand side of the gas control valve by
m
eans of a suitable threaded coupling.
I
n making the connection to the refrigerator, a gas cock of
a
n approved type for use on LPG must be incorporated in
t
he supply line in a position which is readily accessible to
t
he user. For eventual servicing purposes, the union should
b
e on the outlet side of the cock and the pipework should
b
e positioned so as not to prevent the refrigerator from
b
eing readily withdrawn.
E
LECTRICAL CONNECTION
T
he electrical installation must be carried out in a proper
a
nd durable manner, taking into account all relevant regu-
l
ations and codes of practice. For mains voltage operation,
i
t is important that the circuit to and in the caravan is effec-
t
ively earthed.

MPORTANT: The wires in the mains lead of this appliance
a
re coloured in accordance with the following code:
G
REEN-AND-YELLOW = EARTH
B
LUE = NEUTRAL
B
ROWN = LIVE
A
s the colours of the wires may not correspond with the
c
oloured markings identifying the terminals in your plug, in
t
he United Kingdom, proceed as follows:
T
he wire which is coloured GREEN-AND-YELLOW must be
c
onnected to the terminal in the plug which is marked with
t
he letter E or by the earth symbol or coloured green
o
r green-and-yellow.
T
he wire which is coloured BLUE must be connected to the
t
erminal which is marked with the letter N or coloured black.
T
he wire which is coloured BROWN must be connected to
t
he terminal which is marked with the letter L or coloured
r
ed.

ARNING - THIS APPLIANCE MUST BE EARTHED.
I
n the United Kingdom, the plug or circuit to the refrigerator
m
ust be fitted with a fuse not greater than 5 amps. If a 13
a
mp.(B.S.1363) fused plug is used, it should be fitted with a
3
amp. fuse. In other countries, the fuse rating will depend
u
pon the voltage and local practice.

onnect the refrigerator to the vehicle battery or alterna-tor
b
y a direct cable. To avoid a voltage drop, the cross-section
a
rea of the connecting cable between battery/alter-nator
a

T
o ensure satisfactory operation, the positive lead must be
f
itted with a fuse rated at max. 16 A.
T
o prevent the refrigerator from draining the battery, make
s
ure that the current supplied to the caravan is cut off when
t
he vehicle engine is not running, for example by fit-ting an
i
gnition control relay.
