4. With a pair of pliers unfold the lug holding the Iii of the boiler
casing and open the lid.
5. Remove some insulation wool so that the heater is
accessible.
6.
7.
Turn and lift the heater out of its pocket.
Fit the new heater into the pocket and pull on the hose around
the leads.
6. Connect the leads and put on the plastic cover.
9. Reset the insulation and close the lii of the boiler casing.
The Switch
The electric control also comprises an on-off switch operated by
the selector knob at the front panel. The switch has a “on”-
position for 120 Volts A C.
The Thermostat
The electric thermostat is combined with the gas thermostat and
is thus operated by the knob B at the front panel. The tempera-
ture in the refrigerator can be regulated by turning the thermostat
knob to higher or lower numbers. Although the exact setting is
not critical choose a setting at which the frost which gradually
forms on the cooling evaporator is just maintained in dry condi-
tion.
It will be necessary to set the thermostat knob one or two num-
bers higher when the ambient temperature becomes higher or
the load unusually heavy.
If less cooling is required a lower setting should be chosen.
PERIODIC MAINTENANCE
NOTE. Before working on the refrigerator make sure that 120 V
A.C. leads are disconnected.
Shutoff gas valve.
The Burner and the Burner Jet
(Fig. 2) d)
The colour of the flame shall be clear blue over the slots of the
burner (Fig. 3).
Once or twice a year depending on use, it is necessary to clean
and adjust the burner assembly. Proceed as follows:
1. Loosen screw and remove cover plate for burner housing.
2. Disconnect lighter cable from the electrode.
3. Loosen burner fixing screw 19 and withdraw burner.
4. Clean burner tube with a brush. Blow with compressed air.
5. Screw off jet and clean with alcohol. Blow with compressed

The slots of the burner must be centrally located under the boiler
tube.
ODOR FROM FUMES
Causes and remedies
The Electrode
For a proper ignition function it is necessary to keep the electrode
insulation dry and free from din. The gap between burner tube
and electrode shall be max.
3/16"
(5 mm) and min. 1/8" (3 mm).
WARNING
If the refrigerator is used intermittently it should be checked at
least once a year.
It is important to keep the appliance area clear and free from
combustible materials, gasoline and othet flammable vapors and
liquides. The flow of combustion and ventilating air must not be
obstructed. Check the flue baffle that it is clean and reasonably
free from soot. Heavy soot formation indicates improper
functioning of the burner. Clean baffle and flue. Further. clean
cooling unit and floor under refrigerator.
The entire gas installation should be checked for leaks at inter-
vals. Test all pipe connections with soapy water, not with an
open flame.
NOTE. Any service of the gas controls, with exeption for the
above mentioned replacement, maintenance and cleaning
operations must be performed by an authorized service
center only.
FAULT TRACING
The refrigerator does not freeze
satisfactorily
Causes and remedies
a)
b)
c)
Jet orifice clogged. Unscrew jet and blow clear or wash in
alcohol. Do not use wire or pin to clean orifice.
Check the leveling of the refrigerator.
Flame has gone out. Remedy: 1) Gas in bottle is used up -
refill. 2) Feeler point of the flame failure safety device is not
heated enough by flame - check against fig. 2 or 3.
3) Clogged by-pass screw - clean or exchange it.
Air circulation around cooling unit is restricted. Be sure that
refrigerator is properly ventilated.
The evaporator is heavily coated with frost. Defrost.
Flue baffle not inserted into the central tube of the cooling
unit.
The thermostat is incorrectly used. See paragraph on ther-
mostat. In hot weather the setting should be one or two num-
bers “colder” than usual.
Gauze in burner head clogged. Clean.
Burner damaged. Replace.
Burner may be dislocated. Relocate.
Wrong gas pressure at the burner. Have pressure checked at
burner and at gas bottle. Pressure at burner must not fall
below 11 ‘W.G. when thermostat is set on MAX.
a. The flame touches side of the boiler due to dislocation of the
burner. Relocate. Burner dislocation may also cause smoke
and discoloring of walls and ceiling.
b. Burner damaged. Replace.
c. The flame touches flue baffle. Remedy: 1) Burner damaged.
Replace. 2) Flue baffle too low. Correct the position of the
baffle.
d The flue tube is dirty. Clean flue as follows. Cover burner and
jet. Remove flue top and baffle. Clean flue with special flue
brush. Clean baffle before putting back in place.
All the above instructions are to be followed closely. The
refrigerator is quality-guaranteed. However, we are not responsi-
ble for any failures caused by improper adjustments and
unfavorable installation conditions. Contact service point or dis-
tributor service dept. for assistance.
