TROUBLESHOOTING
IF THE APPLIANCE FAILS TO WORK:
Check the following points before calling for service:
1. That the instructions for starting the appliance have been followed.
2. The appliance is level.
3. If it is possible to start the appliance on an alternative energy sources.
4. If the appliance fails to work on gas, check:
a) That the gas bottle is not empty.
b) That the regulator is not faulty.
c) If another appliance is connected to the same supply, check if it works
properly.
5. If the appliance fails to work on 230V (Mains Electricity), check:
a) That the 230V supply is connected to the unit.
b) That there are no loose connections.
c) That the heating element has not burnt out.
d) Check if electric supply is on by feeling if hot air comes out of the top of the
flue (chimney .This will take about 1 hour after switching on).
IF THE APPLIANCE IS NOT COLD ENOUGH IT MAY BE BECAUSE:
1. The ventilation of the absorption unit is inadequate. Allow at least 100mm
around Back, sides, and 600mm above.
2. The evaporator is frosted up – see Defrosting page 8.
3 The gas pressure is incorrect – check the pressure regulator at the gas cylinder
or at the jet (4) of the burner. (Page 10 – Gas burner parts list).
4 If the jet (4) is blocked, remove the jet, clean with alcohol or other solvent and
blow through with compressed air. Never use a piece of wire or a pin to clean
the jet. (Page 10 – Gas burner parts list).
5 Check that you have the correct regulator for the cylinder and gas type that you
are using.
6 You have run out of gas.
7. The ambient temperature is too high.

8
Author: Rudi Version: 2.1 Revision: 1.2 Revision Date: June 2019
8. Too many products are loaded into the freezer at one time – air must be able to
circulate freely.
9. The lid is not properly closed or the lid seal is defective.
10. The baffle has not been inserted into the chimney.
11. The absorption unit is leaking. In the case of a visible leak, there will be traces
of a yellow deposit at the point where the ammonia is escaping. If there is a
leak on the evaporator inside the cabinet, a smell of ammonia may be
noticeable inside the bin. If a leak is detected, under NO circumstances should
you try to repair it, as the unit is pressurized with hydrogen and may explode if
welding is attempted on the unit. Call a qualified service technician. Turn off
the gas or electric supply, and then empty the appliance. If it is in a small room
or in sleeping quarters and the smell of ammonia persist remove the appliance
to a well ventilated area. Do not try to use it.
12 There may be a drop in supply voltage, electric function only.
13. If the flame is not burning after releasing the fail-safe valve knob according to
the instructions, there may be two faults, these being:
a) The magnet in the flame failure device (3) is faulty.
b) The thermocouple feeler point (6) may not be in the flame properly.
To rectify this, loosen the thermocouple nuts (7) and adjust the thermocouple
until the point is over the second row of the small holes in the burner and re-
tighten the nuts on the thermocouple. Repeat the starting instructions and
lighting procedure as laid out on page 5. (USER OPERATING INSTRUCTIONS
–TO START GAS OPERATION)
14. If the appliance is still not working properly, call a qualified service technician to
repair it.
SOME USEFUL HINTS
Make sure that:
1. Defrosting is carried out periodically.
2. The appliance is clean and dry with the lid open when it is not to be used for
some time. If the appliance is fitted with a locking device – remove key to
prevent accidental locking.
3. Liquids or items with strong odours are well packaged.
4. The ventilation of the absorption unit is not obstructed.
5. You do not touch the absorption unit while it is in operation as parts of it will be
extremely hot.
6. You check the condition of the gas supply tube regularly:
a) End fitting in good condition.
b) Overall appearance etc.

7. You have switched on the appliance for approximately 12 hours prior to loading
it with products. Avoid packing products in too tightly – air must be able to
circulate freely
8. You never put bottles or cans of fizzy drinks in the freezer compartment as they
may burst when freezing. Also, do not give children ice-lollies straight from the
freezer compartment as they may cause frost burns.
9. Hot liquids and food are not introduced directly into the freezer, allow them to
cool down first.
10. You are aware that the temperature inside the appliance can vary
according to the ambient temperature, the location of the freezer, the frequency
with which the lid is opened, and the volume and concentration of products
stored in it.
11. You avoid packing products in too tightly – air must be able to circulate freely.
12. For the safety of children keep the key out of children’s reach at all times.
13. It is recommended that a suitably qualified person carry out a yearly service
check.
CLEANING YOUR FREEZER
Clean the bin of the appliance using ½ a litre of warm water and a tablespoon
of bicarbonate of soda.
Soak a soft cloth in the solution, wring it out, and use it to clean out the interior
of the freezer compartment and its fittings.
Do not use wax polish, scouring powder, strong scented products or household
cleaners and detergent to clean the interior of the appliance as they may
damage the surface and leave a strong odour.
The exterior of the appliance should be wiped clean periodically using a damp
cloth and a small quantity of household detergent. The lid seal should only be
cleaned with soap and water and then thoroughly dried. The absorption unit at
the side of the appliance should be cleaned with a brush or feather duster from
time to time, but make sure that the appliance is switched off and has cooled
down when doing this.
DEFROSTING
WARNING:
Normally the temperature of items would rise during defrosting and so, they
should be consumed within 24 hours or discarded.
Do not try to accelerate defrosting by using any kind of heating appliance, as this
may damage the internal surfaces of the freezer.
No sharp object to be used to scrape off the ice as this may damage the internal
surfaces of the freezer.
Frost will gradually accumulate on the freezer surface. It must not be allowed
to grow thick as it acts as an insulator and adversely affects freezer
performance.

10
Author: Rudi Version: 2.1 Revision: 1.2 Revision Date: June 2019
Check the formation of frost regularly and when it gets around 5mm thick,
defrost the appliance.
To defrost the appliance, turn it off and remove all food items.
Once defrosting is complete, clean the interior thoroughly.
IMPORTANT:
Before using the freezer again, ensure that no foreign bodies are present in the flue
chimney, or the burner (dust, insect, nests, waste paper etc.)
WARNING:
The needle valve screw used for admitting the ammonia / hydrogen filling charge to
an absorption unit is fitted to the unit’s reservoir. It is a strictly applied provision of
the guarantee extended on the unit to the customer, that any interference with the
filling valve screw will automatically void the guarantee. The absorption unit must
not be opened, since it contains corroding chemicals under high pressure.
