Installation Instructions

Important Information for the User

Only a registered LP Gas installer may install a gas installation. Ask to be shown the installer's registration card and note the Installer QCC number. Upon completion, the installer must explain operational details and safety instructions. Sign acceptance only when satisfied and obtain a completion certificate. Your invoice is required for guarantee claims.

Important Information for the Installer

Installations must comply with SANS 10087-1, fire department regulations, and local bylaws. Consult relevant authorities if in doubt. Fully explain and demonstrate operational details and safety practices to the user upon completion.

Step 1: Ensure the Appliance is Standing Level!

If positioning on uneven or soft ground, use two flat pieces of wood or hard material (approx. 600mm long, 100mm wide, 20mm thick) under the feet, from front to back, to level the appliance.

Step 2: Positioning

Place the appliance in a cool, well-ventilated area, out of direct sunlight and strong gusts of wind. Allow at least 100mm space around the sides and back, and 600mm above.

Step 3: Preparation

Remove all loose items from the appliance. Ensure adequate space to easily reach controls at the back.

Gas Connection and Operation

Note: Any gas supply cylinder should have at least 250mm clearance if placed behind the appliance.

Gas Connection: The appliance inlet is an 8mm plain straight tube for a gas-tight compression fitting. The freezer is suitable for butane at 2.8-3.0 kPa and propane at 3.7 kPa. Ensure a means to turn off the gas supply is provided. If the supply is common to other appliances, fit a separate tap for the freezer line.

Gas-Pressure Regulator: An operating pressure of 2.8 kPa is required. A suitable LPG regulator complying with SANS 1237 must be installed.

Operating Instructions for Refrigerator Freezer: Read these instructions carefully before use and retain for future reference.

LP Gas Operation: After installation, cylinder change, or servicing, briefly press the safety valve knob (A) to allow air to escape from gas pipes. This ensures quick flame lighting. Do not press knob A for more than 5 seconds.

Burn-Back (Fire in Burner Tube or Chamber): In case of burn-back, immediately turn off the gas supply at the control valve. After extinguishing the flame, re-light normally. If burn-back occurs again, close the valve and call a service technician. Do not use until declared safe.

Warning: This appliance consumes air (oxygen). Ensure ample ventilation, especially when sleeping. Do not use in unventilated structures. Provide additional ventilation for other fuel-burning appliances and occupants. Ensure the flue (chimney) is not covered or blocked.

For Your Safety - If you smell gas:

1. Turn off gas supply at the bottle.
2. Extinguish all naked flames.
3. Do not operate any electrical appliances.
4. Ventilate the area.
5. Do not smoke while checking for leaks.
6. Do not check for leaks with an open flame.
7. If the odour persists, contact your dealer or gas supplier immediately.

Do not store or use gasoline or other flammable vapor and liquid in the vicinity of this or any other appliance.

User Operating Instructions

To Start Electric Operation

1. Ensure the gas supply to the appliance is turned off.
2. Plug in the electrical plug.

Note: The appliance cannot be run off two heat sources simultaneously.

To Start Gas Operation

1. Ensure the electrical supply to the appliance is turned off.
2. Open the shut-off valve for the gas bottle or gas installation.
3. Open flap B.
4. Keep the flame failure device knob (A) pressed in for approximately 5 seconds to allow gas to flow to the burner.
5. Strike a match and insert into flap hole (B). While the flame is burning, press and hold the flame failure device for a further 10 seconds. The burner will now burn with a blue flame.
6. If the flame goes out, repeat steps 4, 5, and 6 until the flame stays alight.
7. The appliance should be left running for a minimum of 12 hours before being loaded with products.
8. To terminate gas operation, turn off the shut-off valve on the gas bottle or gas installation.

Users Note: The gas safety valve knob (A) should never be depressed for periods longer than 5 seconds with the burner unlit, as this can cause a potentially dangerous build-up of unburnt gas. If the burner does not ignite, allow sufficient time for any unburnt gas to disperse, and then repeat the ignition steps.

Troubleshooting

If the Appliance Fails to Work:

1. Check that the instructions for starting the appliance have been followed.
2. The appliance is level.
3. If possible, start the unit on any of the connected sources of energy.
4. If the appliance fails to work on gas, check:
   • a) That the gas bottle is not empty.
   • b) That all LP gas valves are open.
   • c) That the regulator is not faulty.
   • d) 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).

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).
3. The gas pressure is incorrect – check the pressure regulator at the gas cylinder or at the jet (6) of the burner. (Page 9 – Gas burner parts list).
4. If the jet (6) 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 9 – 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. Too many products are loaded into the refrigerator/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 (factory fitted).
11. The absorption unit is leaking. 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. Call a qualified service technician. Turn off the gas or electric supply, and then empty the appliance. If the smell of ammonia persists in a small room or sleeping quarters, 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, there may be two faults: a) The magnet in the flame failure device (2) is faulty. b) The thermocouple feeler point (12) may not be in the flame properly. To rectify this, loosen the bottom nut to the feeler point, push forward until the point is over the burner, and then tighten the top nut. Repeat starting instructions. If the appliance still fails to work, contact a service agent as the valve may be faulty or the flame detector misplaced.
14. If the appliance is still not working properly, call a qualified service technician to repair it.

Some Useful Hints

• Defrosting is carried out periodically.
• The appliance is clean and dry with the lid open when not in use. Remove key from locking device to prevent accidental locking.
• Liquids or items with strong odours are well packaged.
• The ventilation of the absorption unit is not obstructed.
• Do not touch the absorption unit while it is in operation as parts of it will be extremely hot.
• Check the condition of the gas supply tube regularly (end fitting, overall appearance).
• Switch on the appliance for approximately 12 hours prior to loading with products. Avoid packing products too tightly; air must circulate freely.
• Do not put bottles or cans of fizzy drinks in the freezer compartment as they may burst. Do not give children ice-lollies straight from the freezer compartment as they may cause frost burns.
• Do not introduce hot liquids and food into the refrigerator/freezer; allow them to cool first.
• Be aware that the temperature inside the appliance can vary according to ambient temperature, location, lid opening frequency, and volume/concentration of products stored.
• Avoid packing products too tightly – air must be able to circulate freely.
• For the safety of children, keep the key out of reach at all times.
• It is recommended that a suitably qualified person carry out a yearly service check.

Cleaning Your Refrigerator Freezer

• Clean the bins using 1½ litre of warm water and a tablespoon of bicarbonate of soda.
• Soak a soft cloth in the solution, wring it out, and clean the interior of the refrigerator and freezer compartments and fittings.
• Do not use wax polish, scouring powder, strong scented products, or household cleaners and detergent to clean the interior, as they may damage the surface and leave a strong odour.
• Wipe the exterior periodically with a damp cloth and a small quantity of detergent. Clean the lid seal only with soap and water and then thoroughly dry. Clean the absorption unit behind the appliance with a brush from time to time, ensuring the appliance is switched off.

Defrosting

Warning: The temperature of items may rise during defrosting and should be consumed within 24 hours or discarded.

• Do not try to accelerate defrosting with any kind of heating appliance, as this might damage the internal surfaces. Do not use sharp objects to scrape off ice.
• Frost will gradually accumulate. Do not allow it to grow thick as it acts as an insulator and adversely affects freezer performance.
• Check frost formation regularly and when it is around 5mm thick, defrost the appliance.
• To defrost, turn off the appliance and remove all food items.
• Once defrosting is complete, clean the interior thoroughly.

Prolonged Storage

• Disconnect all electrical connections and the gas supply.
• Empty the freezer. Defrost and clean it thoroughly.
• Leave the lid partially open to prevent any odours and moulds forming.

Important: Before using the freezer again, ensure that no foreign bodies are present in the flue chimney, or the burner (dust, insects, nests, waste paper etc.).

Warning: The needle valve screw for admitting ammonia/hydrogen filling charge to the absorption unit is fitted to the unit's reservoir. Interference with this screw will automatically void the guarantee. The absorption unit must not be opened, as it contains corroding chemicals under high pressure.

Service Notes

Routine Maintenance

It is recommended that a suitably qualified person service this appliance at least once a year.

• Inspect the gas hose for cracks and chafing marks. Test all connections with a suitable solution; do not use an open flame.
• Check for any smell of ammonia or signs of green/yellow crystal-like deposits on the cooling unit tubes. Smell or deposits indicate a leaking unit.
• Check the functioning of the flame failure control and adjust if necessary.
• Check the functioning of the ignition device if fitted and adjust if necessary.
• Check the control knobs turn freely.
• Examine the burner flame – ensure burning with a sharp blue flame and no yellow tipping or sooting.
• Check the door/lid seals are in good condition.
• Do not let children play with the appliance.
• Cleaning and user maintenance should not be done by children without supervision.

In the Event of Failure

If the burner will not light:

• Check adequate gas supply – through to burner.
• Depress flame failure device for 15sec and try lighting with a match. This must be done in a well-ventilated area.

Qualified Technician

• Check jet is clean – if not, clean with solvent and blow dry. Do not try to clean with pin or similar.
• If the burner will not stay alight, check position of the thermocouple head, and the functioning of the safety valve.

If not cold enough:

• Check through points listed under Troubleshooting.
• In the unlikely event of cooling unit failure, contact the national distributor without delay.

If too cold (in the fridge compartment):

In colder weather conditions, the fridge compartment may drop below 0°C. When this happens, open the lid by approximately 40mm by placing an object between the lid and surround until the cold weather conditions improve. This will ensure that the fresh produce doesn't freeze.

Important Note: If there is a smell of ammonia, it is advised that the user turn off the appliance, clear out all the food and remove the appliance from dwelling areas.
