Remove the lower trim moulding and then withdraw the
panel by sliding it downwards.
Fit new panel in place and slide it up as far as possible.
Fit the trim moulding back in place.

BUILDING-IN

The refrigerator is intended for installation in a caravan or
motorhome, and the description relates to this application.
The refrigerator must not be exposed to radiated heat from
hot objects (e.g. below a cooker without proper heat shiel-
ding).
Excessive heat irradiation impairs performance and leads to
increased energy consumption. For this reason the refrige-
rator should be installed if possible not at the entrance side
of the vehicle - normally orientated south and often with an
awning - which would impair the dispersion of heat and
combustion gases from the ventilation openings.
It is not a good practice to install the refrigerator so that the
vent openings are covered by the vehicle's entrance door
when this is open. This would reduce the ventilation air flow
to the cooling unit and reduce refrigeration performance.
The enclosure
The refrigerator must be installed in an enclosure, the
dimensions of which are shown in TECHNICAL DATA.
The bottom of the enclosure must be horizontal and even
so that the refrigerator can be easily pushed into place. It
must be sturdy enough to carry the wieght of the refrigera-
tor.
Battens must be installed at the enclosure and fitted with
sealing strips, as shown in fig. 4.
Slide in the refrigerator until it is flush with the front of the
recess. There must be 10-20 mm free space behind the
refrigerator.
Four fasteners are fitted in plastic bushings in the side walls
of the fridge, fig. 7. They are used for securing the refrigera-
tor in the enclosure.
The side walls of the enclosure and/or any wooden braces
installed to hold the refrigerator must be dimensioned to
seat the screws securely, also considering the forces due to
the movement of the vehicle.
With the refrigerator in place, drive the screws through the
bushings in the lining of the refrigerator into the walls of the
enclosure. There must not be more than 3mm of clearance
between refrigerator and enclosure on each side. If neces-
sary, wooden strips or similar should be fitted.
Note: This is the only approved means of securing the
refrigerator to the enclosure and to the vehicle. Fasteners
penetrating other parts of the insulation (PU) foam of the
refrigerator might damage components like electric wiring
etc.

VENTILATION OF THE UNIT

At high ambient temperatures the refrigeration unit will only
perform adequately when properly ventilated.
The refrigeration unit is ventilated via two openings in the
wall of the caravan (see fig. 5). Fresh air enters through the
lower opening and warm air is discharged through the upper
one.
Locate the lower opening immediately above the floor of the
recess, and the upper one as high as possible above the
condenser (C) of the refrigeration unit, at least as shown in
fig. 6b but preferably as shown in fig. 6a.
Ventilation grilles Fig. 2
The openings in the caravan wall must be fitted with the
Electrolux ventilation systems.
Fitting the grilles, model A 1620, which were specially
developed by Electrolux for this purpose (shown as D in fig.
6). It is a good idea, to install the frame R 1640 (A in the
same figure), at the same time. Then the grilles can be
easily removed which permits inspection and small repairs
to be carried out without the necessity for removing the
refrigerator from the recess.
If there is no outer grille at floor level where leaking gas can
escape, a 40 mm hole to the outside should be made in the
floor of the recess to drain any unburnt gas to the outside
gas.
Fit the hole with wire mesh and an angled plate to protect
from stones, mud etc.
Removal of flue gases
The ventilation passage at the rear of the recess, between
the outer wall of the vehicle and the refrigerator (fig. 6), is
sealed off against the living space, and so cold draughts are
excluded (winter camping) and no flue gases can penetrate
into the vehicle. Thus a special flue outlet is no longer
necessary - the gases are dispersed through the upper vent
grille.
Note: With this mode of installation the same type of grilles
(without an integrated flue outlet), should be installed at the
upper as well as at the lower vent open-ning. The angled
T-piece for the flue tube (when delivered) should not be
used in this case.
The top of the enclosure above the flue tube (I), fig. 6,
should be covered with aluminum sheet metal, as indicated
in (B), to facilitate the heat dispersion.
In fig. 6 the letters have the following meaning:
A. Frame R 1640 for the grilles
B. Aluminum cladding
C. Condenser of cooling unit
D. Vent grill A 1620
E. Sealing profile (optional extra)
Width 486 mm, Electrolux art. nr. 295 1147-10
F. Refrigerator rear wall
G. Wooden batten approx. 10 x 20 mm (see fig. 4)
H. Height of the enclosure (see TECHNICAL DATA)
I. Flue tube

LP GAS CONNECTION

CAUTION! CHECK THAT THE GAS SUPPLIED TO THE
REFRIGERATOR IS AT THE CORRECT PRESSURE.
SEE THE REDUCING VALVE ON THE LP GAS
The refrigerator is designed for operation on LP gas of
Butane type the pressure of which must be 28 mbar for
Butane and 37 mbar for Propane.
Check that this is stated on the data plate. The refrigerator
is not designed for operation on town gas or natural gas.
The gas installation should only be carried out by an
authorized gas fitter.
