P Gas operation
A
fter initial installation, servicing, or changing gas cylinders
e
tc., the gas pipes may contain some air which should be
a
llowed to escape by briefly turning on the refrigerator or
o
ther appliances. This will ensure that the flame lights
i
mmediately.
T
o 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.

E
LECTROLUX ventilation grilles A 1620 (fig 2), can be
f
itted with winter covers, model 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 the 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 months.

EGULATING THE TEMPERATURE
T
he position number refers to fig. 3.
I
t will take a few hours for the refrigerator to reach normal
o
perating temperature. So we suggest you start it well in
a
dvance of a trip and if possible store it with precooled
f
oodstuffs.
O
n 230 V operation the refrigerator is controlled by a ther-
m
ostat and the thermostat knob (C) 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.
O
n LP gas operation the refrigerator temperature is regula-
t
ed by the gas thermostat (E), which should be set at 3-5. If
a
lower (colder) temperature is desired, set the thermostat
t
o a higher figure.
