until they start discharging fluid. Start the
circulation pump and let it run for a while.
Check that the pipes and radiators around
the vehicle are heating up. If they still fail to
heat up, try the following:
Single-axle caravans: Stop the circulation
pump. Using the jockey wheel, lower the
front of the caravan as far as possible so that
the rear is tilted upwards. Leave it in this
position for a few minutes to allow the air to
travel upwards in the system. Open the
bleeder screw at the highest point. Leave it
open until it discharges glycol fluid.
Using the jockey wheel, raise the front of the
caravan as far as possible and repeat the
procedure in this position. Then position the
caravan horizontally and start the circulation
pump. Check that the pipes and radiators
around the vehicle are heating up.
Motor caravan or twin-axle caravan: The
easiest way to bleed the heating system is to
place the vehicle on a sloping surface or to
raise one end of the vehicle using a jack.
Bleed the system as described above.
SETTINGS FOR THE OPERATION OF THE
HEATING SYSTEM AND WARM WATER
HEATER
For more information on the settings on the
control panels, please refer to sections on
the SC20 and TP5000.
WARM WATER ONLY WITH 230V HEATING
CARTRIDGE
1. Set the SC20 ‘Circulating Pump Switch’
to off.
2. Set the SC20 ‘Gas Burner on/off’ switch
to off.
3. Switch the SC20 ‘1kW heating element
on/off’ switch to on.
Please note when the system is being used
for warm water only, the electronics limit
output to 1kW, irrespective of the output
actually selected.
WARM WATER ONLY WITH LPG BOILER
1. Ensure that the gas supply is connected
and all relevant valves (bottle, manifold)
are open.
2. Set the SC20 ‘Circulating Pump Switch’
to off.
3. Set the SC20 ‘Gas Burner on/off’ switch
to on.
4. Set the SC20 ‘1kw heating element
on/off’ and ‘2kW heating element on/off’
switches to off.
HEATING AND WARM WATER WITH 230V
HEATING CARTRIDGE
1. Set the SC20 ‘Circulating Pump Switch’
to on.
2. Set the SC20 ‘Gas Burner on/off’ switch
to off.
3. Switch the SC20 ‘1kW heating element
on/off’ switch and ‘2kW heating element
on/off’ switches together to select a total
of 1kW, 2kW or 3kW as desired, taking
into account the 230V supply available to
the caravan. (See appliance consumption
figures elsewhere in this manual)
4. Use the TP5000 programmable room
thermostat to determine heating operating
times and desired room temperature.
