Securing in the Recess
The refrigerator must be secured in the recess to prevent movement. The method suggested in item 8 may be adopted, or wooden
battens may be screwed to the sides of the recess, bearing down on the top of the cabinet from front to back, to hold it firmly as
shown at A, fig. 7. Whichever method is used, it must be possible to remove the refrigerator easily for subsequent servicing
purposes. The brackets or battens must be in a position where they will not restrict the air circulation over the cooling unit; they
must not be positioned across the cabinet over the ventilation openings in the top rear of the casing, or over the fins of the
condenser protruding from the cooling unit at the rear, otherwise air-flow will be impaired and performance affected.
Fitting the Upper Ventilator
To fit the upper ventilator, screw a block of wood approx. 25mm
(1") square x 66mm (2 5/8 ") long, to each side of the recess,
16mm (5/8") from the front edge, as shown at B, fig. 7. Secure
the ventilator to the blocks with a screw through the hole
provided at each end.
If any other type of ventilator is used, the total area of the
openings in it for the passage of air must not be less than 240
2
cm2 (37 in
).
Additional Ventilator
To reduce the amount of heat entering the caravan, particularly
when used in warmer climates, it is recommended that an addi-
tional ventilator (A, fig. 4), is fitted in the wall of the vehicle, preferably above the level of the top of the refrigerator. (The exterior
flue venting kit must still be used).
10. VENT HOLE UNDER REFRIGERATOR
A ventilation hole of not less than 13 cm
refrigerator as shown in figs. 4 & 13. The hole should not be directly under or close to the burner where draught could affect the
flame, but must lead directly to the outside air through the floor or' wall so
that, in the event of a gas leak, it would provide an escape outlet for the
heavier-than-air gas.
On mobile installations, the vent hole should be shielded against entry of
mud etc., by a deflector as shown in fig. 8, fitted underneath with its
closed" end facing the front of the vehicle.
11. FLUE ARRANGEMENT
Flue Baffle
The flue baffle must be in position in the central tube of the boiler,
suspended on its support wire so that the lower edge of the baffle is 75 mm (3") above the bottom of the central tube. The top end
of the baffle support wire is bent into the shape of an "0", and rests horizontally on the top of the boiler central tube. If the flue baffle
is missing or incorrectly located, the cooling unit will not operate properly on gas.
Flue Venting Kit
The flue gases must be vented directly to the outside air.
Only the ELECTROLUX flue venting kit (supplied with the refrigerator in the
United Kingdom), is recommended for this purpose. It consists of the following
parts, (see fig.9).
A.
Screw (4 off) 1 1/4" No.6
B.
Outer Cover
C.
Flue Outlet
D.
Cover Washer (inner)
E.
Screw (4 off) 3/8" No. 6
F.
Extension Tube for flue top
G.
Flue Top ('lazy T')
H.
Heat-resistant rubber flap
The flue top (G) is in the form of a lazy "T" and incorporates an air-break to
minimise the possibility of flame extinction due to draughts.
There is a choice of two positions for fitting the flue venting kit, thus varying the
height of the outlet in relation to the top of the refrigerator as shown in figs. 10 and 11. The position best suited for each particular
installation should be decided
