If the caravan is not used during the
winter the boiler must be drained
prior to storage
• Disconnect power for water pump.
• Open hot the water tap in the bathroom
and kitchen.
• Open safety/drain valve: Move the lever to
vertical position f.
The water heater is now drained directly to
the outside via the safety/drain valve. Check
that the water contents have been completely
drained (10 litres).
If just the cold water system is being operated
without using the water heater, the heater tank
also fills up with water. To avoid frost damage
the boiler must be drained through the drain
valve even if it was not operated.
When connecting to a central water supply
(rural or city mains) a pressure reduction valve
must always be installed to prevent above 2.8
bar from developing in the water heater.
There shall be no claims under guarantee for
damage caused by frost.

Heating is possible with gas, electrical and
mixed operation. Also with or without water.
Check to make sure the flue is
unobstructed. Be sure to remove any
covers that may be present.
• Turn on gas cylinder and open isolating
tap in the gas supply line.
• Check whether the power supply fuse
protection on the camp site is adequate
for the 900W (3.9A) or 1800W (7.8A)
that has been selected using the power
selector switch.
• Fill boiler with water if necessary.
• Switch on the unit on the control panel.
S
WITCHING OFF
• Switch the heater off on the control panel.
• The switch-off procedure may be delayed
by several minutes because of internal
heater operations.
Always drain water contents if there is
a risk of frost
If the appliance is not used for a long period,
close the quick acting valve in the gas supply
line and the gas cylinder.
M
AINTENANCE
Only original Truma parts may be used for
maintenance and repair work.
• Clean the compartment where the unit is
installed at least once annually.
• Have an expert check the unit for dirt and
clean it if necessary.
• The safety/drain valve must be operated
regularly (at least twice annually) to
remove limescale deposits and to be
certain that it is not blocked.
We recommend the use of suitable
commercially available products to clean,
sterilise and maintain the boiler. Products
containing chlorine are not suitable.
The effectiveness of the use of chemicals to
combat micro-organisms in the appliance can
be increased by heating the water in the boiler
to 70 °C at regular intervals.
• Select “Gas mode”.
• Set the water temperature to 60 °C.
• Switch on the appliance.
Once the water in the boiler has
reached a temperature of 60 °C, the
burner will switch off. The appliance
must stay switched on for at least
30 minutes and no hot water may be
removed. The residual heat in the heat
exchanger will heat the water up to
70 °C.
