Dometic RM760 Refrigerator User Manual


 
Frozen Food Storage Compartment
The ice trays should be placed in direct contact with the
freezer shelf for fastest ice making. Quick frozen soft fruits and
ice cream should be placed in the coldest
part
of the com-
partment which is at the bottom of the aluminum liner or, in
models with a shelf, on this or just below it. Frozen vegetables,
on the other hand, may be stored in any part of the compart-
ment.
The compartment is not designed for the deep or quick fre-
ezing of foodstuffs. Meat or fish foods, whether raw or prepa-
red, and provided they are
precooled
in the refrigerator, can
however, also be stored in the frozen food storage compart-
ment. They can then be stored about three times as long as in
the fresh food storage compartment. To prevent drying out,
keep food in
coverd
dishes, in plastic bags or wrapped in
aluminum foil.
Ice Making
Ice cubes can be made in the ice trays which should be filled
with water to within
1/4"
(5 mm) from the top. To release the
ice cubes seize the tray with both hands and twist the tray as
shown in fig 0. Cubes not required should preferably be
replaced in the tray. Refill the tray with water and replace the
tray on the freezer shelf.
Ice making is accelerated if the thermostat knob is turned to
setting “MAX”. It is a good idea to do this a few hours before
an anticipated need for ice but be sure to turn the knob back to
normal setting when the ice is formed or the foodstuffs in the
cabinet may become frozen hard.
To Shut Off the Refrigerator
To shut off the refrigerator turn the knob A to off position. If the
cabinet is not in operation over a period of weeks, it should be
emptied and cleaned and the door left ajar. Some models are
provided with interior light, which comes on when the door is
opened. To avoid running out of battery the light should be
shut off with the knob underneath the lamp housing. The ice
trays should also be dried and kept outside the cabinet.
Cleaning
To clean the interior lining of the refrigerator use lukewarm
weak soda solution. The evaporator, ice trays and shelves
must, however, be cleaned with warm water only. Never use
strong chemicals or abrasives to clean these parts or the
protective surface will be spoiled. It is important always to
keep the refrigerator clean.
CAUTION
Do not store explosive substances in the refrigerator, such
as cigarette lighter gas, petrol, ether or the like.
GAS EQUIPMENT
Flue Top and Baffle
The flue baffle is suspended from the top and must be in
position in the central tube of the cooling unit.
The Burner and the Burner Jet (Fig. 2)
The slots of the burner must be centrally located under the
boiler tube.
See “Periodic maintenance”.

The Flame Failure Safety Device (Fig. 3)
The feeler of the
thermo
couple shall reach in over two slots of
the burner. To replace the
thermo
couple proceed as follows:
1.

7.
Remove the plastic cover 22 (Fig. 5).
Unscrew plug 20 and pull thermo-couple straight out.
Remove spring 21.
Pull out thermo-couple sideways from burner housing.
Bend the new thermo-couple to the same shape as the old
one.
Reassemble in reverse order. Check that feeler has been
correctly refitted in relation to burner. See Fig. 3.
Mount plug 20, taking care not to damage the threaded
hole in the aluminum cap of the housing. The plug must be
properly tightened to the valve housing to ensure good
contact between the thermo-couple and the magnetic coil
within the housing.
The Thermostat
The refrigerator is equipped with a thermostat which is regula-
ted by turning the knob to different settings in order to obtain
the desired controlled cabinet temperature.
At OFF
At MAX
Under normal operating conditions the thermostat
valve remains closed and the burner is running con-
tinuously at the by-pass rate, just enough to keep
the burner lit.
The thermostat valve remains open and the burner
is running continuously at full gas rate. Lowest cabi-
net and freezer temperatures are obtained at this
setting.
Between these two extremes is a numbered protion of the dial
over which various controlled temperatures can be obtained,
the higher the number, the lower the temperature.
As soon as the required cold temperature inside the cabinet is
reached, the thermostat cuts the burner main flame leaving
the by-pass flame to keep the safety valve open.
The Igniter
The refrigerator is fitted either with a piezo igniter (see fig. 4a)
or an automatic reigniter (see fig. 4b). which does not normally
need any maintenance. If the igniter does not work properly
contact an authorized service point.
ELECTRIC EQUIPMENT
Cartridge heater
The refrigerator is equipped also for electric operation. Most
models are equipped for both 120 Volts A C and 12 Volts D C
operation.
The heat necessary for the operation of an absorption type
cooling unit is supplied by an electric cartridge heater
mounted in a pocket of the boiler system.
To replace the heater first of course check that the wall plug is
disconnected. If the refrigerator is equipped also for 12 Volts
D C operation make sure that the 12 V leads are disconnec-
ted. Then proceed as follows:
1. Remove the plastic cover (22) of the main control structure
by loosening the two screws
2. Disconnect the heater leads
3. Pull off the metal hose
