1. Turn the thermostat knob to 1 (lowest system temperature)
and check that the main flame goes out, as it should.
2. Check that the sensor is secured correctly. It should be at-
tached to the body of the boiler by a spring clip just under
the control box with heat-conducting putty in between.
3. If this does not help, contact your service workshop.
Vibrations in the circulation pump (12-volt)
1. Release the nut holding the circulation pump.
2. Turn the pump a little and tighten up the nut again.
3. Check that the rubber connection between the motor and
the shaft is straight and does not wobble when in motion.
4. Check that there is no obstruction in the way of the pump at
the bottom of the expansion vessel.
5. If this does not help, contact your service workshop.
Noise in the motor of the circulation pump (12-volt)
1. Drop a drop of sewing machine oil into the centre hole at
the top of the motor.
2. If the noise does not disappear or returns after a while, the
motor should be replaced.
Circulation pump (12-volt) will not start
1. Check that the slider on the room thermostat is in "ON" posi-
tion.
2. Check that the temperature shown on the room thermostat
is higher than inside the caravan.
3. Check that the changeover switch on the control panel for
the circulation pump is on "12-volt pump".
4. Remove the circulation pump and check that the cables are
properly secured, and that there is a 12-volt supply.
5. If this does not help, contact your service workshop.
Incorrect temperature on the room thermostat
1. Check by using an accurate thermometer inside the cara-
van.
2. Remove the cover from the room thermostat (press in the
pin on the left-hand side and pull the cover straight out).
3. Pull out the knob and move it as many degrees up or down
as it indicated wrongly, and press it into place again.
4. Replace the cover and check that the temperature agrees
with the scale on the room thermostat.
The immersion heater has stopped working
1. Check that there is power (230 volts) in the wall socket.
2. Check that the relays on the immersion heater switch on (a
gentle click should be heard).
3. Check whether the overheating protection has triggered. If
so, press in the button on the side of the cover.
4. If this does not help, contact the service workshop.
