TROUBLESHOOTING
IF THE COOLER FAILS TO WORK
:
Check the following points before calling for service:
1. That the instructions for starting the cooler have been followed.
2. The cooler is level.
3. If the cooler fails to work 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.
IF THE COOLER IS NOT COLD ENOUGH IT MAY BE BECAUSE:
1. The ventilation of the absorption unit is inadequate. Allow at least 100mm around
the back and sides of the cooler 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
the orifice (7) of the burner. If the orifice (7) is blocked, remove orifice, clean with
alcohol or other solvent and blow through with compressed air. Never use a piece of
wire or a pin. Check that you have the correct regulator for the cylinder (2.8-3.0 kpa
butane, 3.7 kPa propane). Check that you have not run out of gas.
4. The ambient temperature is too high.
5. Too many products are loaded into the cooler at one time.
6. The lid is not properly closed or the lid seal is defective.
7. The baffle has not been inserted into the chimney. (factory fitted).
8. The absorption unit is leaking. A leak can be determined in the case of a visible leak,
by 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 may be noticeable.
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 leak. Call a
qualified service technician. Turn off the gas or electric supply, and then empty the
cooler. If it is in a small room or in sleeping quarters or the smell of ammonia persists
remove the appliance. Do not try to use it.
9. If the flame fails to stay alight after releasing the fail-safe valve knob according to the
instructions, there may be two faults, these being:
a) The magnet in the fail-safe valve is faulty.
b) The thermocouple feeler point (8) 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, and then tighten the top nut on the feeler point.
Repeat starting instructions.
Repeat lighting procedure. If still fails contact a service agent as the valve may be
faulty or the flame detector misplaced.
10. If the cooler is still not working properly, call a qualified service technician to repair
it.
