✓ The refrigerator can be run on 220 volt and LP Gas.

✓ The gas electric thermostat, [A], carries out charges between these operations.

✓ 12-volt option on models CR100, GEV70 and CR35 only.

Warning: - These are camping models and should not be exposed to rain.

To Start Operation: GR280, GR265, GR245, CR100 and GEV70

LP Gas Operation:

1. Open the shut-off valve for the gas bottle. (Check that there is enough gas). Open any shut-off valve of the gas installation.

2. Turn on the gas supply by turning the thermostat knob, [A], to the high position, No. 4.

3. Push in and turn knob [B] to gas (3 o’clock) position.

4. Keep the flame failure device knob, [B], pressed in for approximately 15 seconds and simultaneously operate the igniter, [E], until the flame lights by pressing in and then releasing the button.

5. Keep the knob, [B], pressed in for a further 15 seconds then release it. During this time the gas flame indicator, [C], and needle will move into the green section, designating the flame is burning. If the needle returns to its original place, repeat steps 3, 4 and 5 until the needle remains in the green section.

• To terminate gas operation, push in and turn knob [B] to the OFF (6 o’clock) position.

Note: 4

❑ If the piezo-electric igniter, [E], does not spark properly, as can occur in extremely damp and humid conditions, the burner can be lit directly with a match by a second person instead of using step number 4.

❑ If strong gusty winds prevail, regularly check the gas flame indicator needle [D] remains in the green section to ensure that the wind has not extinguished the flame. If it has, repeat steps 3, 4 and 5, or use another mode of operation.

❑ After initial installation, changing of gas cylinder, or servicing etc., the gas pipes may contain some air, which should be allowed to escape by briefly pressing on the flame failure device, [B]. This will ensure the flame lights quickly.

❑ It is essential that the 30mBar regulator be used.

❑ In the case of burn back. Turn knob [B] to off position and close valve on cylinder.

❑ If burn back continuous contact your local service agent

❑ To switch on open valve and repeat steps 3,4 and 5.

❑ The flame failure device, [B], should never be depressed for periods longer than 15 seconds with the burner unit, 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 dispense, and then repeat the ignition steps.

220 Volt Operation:

• Turn off gas or 12 volt operation when applicable.

1. Turn the thermostat knob [A], to its coldest position, (fully clockwise), No. 4.

2. Push in and turn knob [B] to the electric (9 o’clock) position.

3. Connect the plug to mains supply and switch on.

12 Volt Operation:

• Only operate your refrigerator on 12 volt when the engine of the vehicle is running; otherwise your battery will soon be discharged.

1. Disconnect 220-volt mains supply or gas supply.

2. Connect to 12-volt supply.

Warning: - If the supply cord is damaged, it must be replaced with a new cord or assembly available from the manufacturer or one of their service agents.

❖ Once the freezer has been switched on, it will take a few hours to become cold.

❖ On LP gas, select 1 – 4 (for coolest position) depending on the desired temperature.

❖ When operating on 220 volt [A] turn clockwise, 1 – 4, for colder and anti-clockwise for warmer.

❖ There is no thermostatic control for 12-volt operation.

LP Gas Operation:

1. Open the shut-off valve for the gas bottle (check that there is enough gas). Open any shut-off valve of the gas installation.

2. Keep the flame failure device, knob [D] pressed in for approximately 15 seconds and simultaneously operate ignitor [E], until flame light by pressing it in and then releasing the button.

3. Keep knob [D] pressed in for a further 15 seconds, then release it. During this the gas flame indicator [B], and needle [C] will move into the green section, showing the flame is burning. If the needle returns to its original place, repeat steps 2, 3 and 4 or use another mode of operation.

• To terminate gas operation, turn off the “Shut-Off” valve on the gas bottle.

Note:

❑ After initial installation, after changing gas cylinder, after servicing etc., the gas pipes may contain some air, which should be allowed to escape by briefly pressing the flame failure device knob [D]. This will ensure the flame lights quickly.

❑ The flame failure device knob [D] should never be depressed for period longer than 15 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 then 6 repeat ignition steps.

❑ In the case of burn back. Turn knob [A] to off position and close the valve on cylinder.

❑ To switch on open valve of cylinder and follow steps 3,4 and 5

❑ If burn back continuous contact your local service agent

❑ If the piezo-electric ignitor [E] does not spark properly, as can occur in extremely damp and humid conditions, the burner can be lit directly with a match by a second person instead of using step number 3.

❑ If strong, gusty winds prevail; regularly check the gas flame indicator needle [C] is still in the green section to ensure that the wind has not extinguished the flame. If it has, repeat steps 2, 3 and 4 or use another mode of operation.

220-Volt Operation:

1. Turn knob [A] of the thermostat to its coldest position (fully clockwise).

2. Connect the plug to mains supply and switch on.

12-Volt Operation:

1. Disconnect 220-volt mains supply or gas supply.

Regulating the temperature

❖ Once the refrigerator has been switched on, it will take a few hours to become cold.

❖ On 220 volt [A] turn clockwise for colder and anti-clockwise for warmer.

❖ There is no thermostatic control on gas or 12 volt operation.

Troubleshooting

If the freezer fails to work check the following points before calling service!!

✓ That the instructions for starting the freezer have been followed

✓ The freezer is level

✓ If it is possible, start the unit on any of the other connected energy sources.

✓ If the freezer fails to work on gas, check:

a. That the gas bottle is not empty

b. That the LP gas valves are open

c. That the regulator is not faulty.

✓ If the freezer fails to work on 220 volt and 12 volt, check:

a. That the 220 volt / 12 volt supply is connected to the unit

b. That there are no loose connections

c. That the heating element has not burned out.

If the Freezer is not cold enough, it may be because…

1. The ventilation of the absorption unit is inadequate; allow at least 50mm around back and sides and 600mm above.

2. The evaporator is frosted up – Refer “Defrosting” Page 8.

3. The temperature control is incorrect – Refer “Regulating the Temperature”, Page 6.

4. The gas pressure is incorrect, check the pressure regulator at the gas cylinder or the orifice of the burner. If the orifice is blocked, remove the orifice, clean with alcohol or other solvent and blow through with compressed air. (Never use a piece of wire or pin).

5. The circulating temperature is too high.

6. Too much food is loaded in at one time.

7. The lid or door is not properly closed or the seal is defective.

8. The baffle has not been inserted into the chimney.

9. There may be a drop in voltage supply.

10. If the flame fails to stay alight after releasing the fail-safe valve knob according to instructions, there may be two (2) faults, these being:

a. The magnet in the fail-safe valve is faulty.

b. The thermocouple feeler point may not be in the flame properly.

To rectify this, loosen the bottom nut to the feeler point and push forward until the point is over the burner, then tighten the top nut on the feeler point. Repeat the starting instructions. Refer “To start operation”, Page 3.

11. The absorption unit is leaking.

N.B: A leak can be determined if there are visible traces of 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 will be noticeable. If a leak is detected, under NO circumstances should you try to repair it, as the unit is pressurised with hydrogen and may explode if welding is attempted on the leak. Call a qualified technician.

• If the freezer is still not working properly, call a qualified service technician to repair it.

Some Useful Hints:

Make sure that:

✓ Defrosting is carried out periodically

✓ The refrigerator is clean and dry with the door open when it is not to be used for some time

✓ Liquids or items with strong odours are well packaged

✓ The ventilation of the absorption unit is not obstructed

✓ You do not touch the absorption unit while it is in operation as parts of it will be extremely hot

✓ You check the condition of the gas supply tube regularly:

• End fittings in good condition

• Overall appearance etc.

✓ You switch on the refrigerator for approximately 12 hours prior to loading it

✓ With foodstuffs and pre-frozen goods are loaded into the freezer compartment

✓ You never put bottles or cans of fizzy drinks in the frozen food storage compartment as 8 they may burst when freezing. Also, do not give children ice-lollies straight from the compartment as they could cause frost burns

✓ Hot liquids and food are not introduced into the refrigerator, allow to cool first

✓ You are aware that the temperature inside the refrigerator can vary according to the circulating temperature, the location of the refrigerator, the frequency with which the door is opened, and the volume and concentration of products stored in it

✓ You avoid packing products in too tightly – air must be able to circulate freely

Cleaning Your Refrigerator

The inside of the refrigerator should be cleaned regularly to keep it fresh and hygienic.

Clean your refrigerator using ½ a litre of warm water and a little bicarbonate of soda. Soak a soft cloth in the solution, wring it out and use it to clean out the interior of the refrigerator and its fittings.

Do not use wax polish, scouring powder, strong scented products or household cleaners and detergents to clean the interior of the refrigerator as they may damage the surface and leave a strong odour.

The door seal, should only be cleaned with soap and water and then thoroughly dried.

The exterior of the refrigerator (except the door seal) should be wiped clean regularly using a damp cloth and a small quantity of detergent.

The absorption unit behind the refrigerator should be cleaned with a brush from time to time, but make sure that the refrigerator is switched off when doing this.

Defrosting

Frost will gradually accumulate on the refrigerator surface.

It must not be allowed to grow thick as it acts as an insulator and adversely affected refrigerator performance.

➢ Check the formation of frost regularly and when it gets around 5mm thick, defrost the refrigerator.

➢ To defrost the refrigerator, turn it off and remove all food items.

Warning:

❖ Normally the temperature of items would rise unduly during defrosting and so, they should be consumed within 24 hours or discarded.

❖ Do not try to accelerate defrosting by defrosting by using any kind of heating appliance, as this might damage the plastic surface of the refrigerator.

❖ Once defrosting is finished, empty out the drip tray and thoroughly clean the interior.

Prolonged Storage

➢ Disconnect all electrical connections and the gas supply.

➢ Empty the refrigerator. Defrost and clean it thoroughly as described earlier.

➢ Leave the door partially open to exclude any odours and moulds forming.

Important:

❖ Before using the refrigerator again, ensure that no foreign bodies are present in the chimney or the burner (dust, insect, nests, 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.
