Troubleshooting
If the fridge fails to work, check the following points before
calling a technician.
• Ensure that the correct procedure has been followed for
starting the refrigerator.
• Check that the fridge is level.
• Ascertain whether it is possible to run the fridge on any of
the energy sources.
• If the fridge fails to work using gas:
• Make sure the gas bottle is not empty.
• Make sure all LP gas valves are open.
• If the fridge does not work on 12V:
• Check the 12 V supply is connected to the refrigerator.
• Ensure that the fuse on the 12 V supply is intact.
• Check the 12 V switch is on.
• If the fridge fails to work on 230V:
• Check the 230V supply is connected to the fridge.
• Make sure the fuse is intact.
If the fridge is not cold enough, it could be due to one of the
following reasons:
• The ventilation is inadequate due to reduced area of the
ventilation passages (partial blockages of the grilles from
wire mesh etc.)
• The evaporator is frosted up.
• The temperature control setting is incorrect.
• The gas pressure is incorrect, check the pressure regulator
at the gas container.
• The ambient temperature is too high.
VEHICLE HEATER
The auto heater is based on an extremely efficient heat
exchanger consisting of a pair of internally and externally
finned aluminium diecastings.
The gas burner is at the bottom of the vertical passage that
permits complete combustion of the gas before meeting with
the heat exchanger surfaces.The combustion products travel
along the top horizontal section then downwards to further
galleries while transferring their heat to the motorhome.
The flue outlet is at the bottom of the heat exchanger thus
ensuring that the majority of the heat extracted from the
combustion path is completely sealed from the living space.
All the air for combustion is drawn from beneath the
motorhome through the air intake and the products of
combustion are discharged through a flue pipe to a
roof-mounted terminal.
The heater is controlled by a knob mounted on the top of
the heater case which operates a thermostatic gas valve.
Ignition is by an electric re-ignition system powered by two
AA size batteries and operated by a micro-switch mounted
on the thermostatic gas control.
Operating Instructions
Before lighting the heater, ensure that the gas supply is
turned on and that the batteries have been fitted to the
ignition unit.
• Turn control knob to thermostat setting 1-10 and press it
down as far as the stop. Ignition takes place automatically
(Ignition sparking audible) until the flame ignites.
