PASSENGER TRANSPORT
1 – Seatbelt usage
Your vehicle is equipped with a certain number of seats for travelling. This number of seats is
specified in the vehicle registration card. These seats are identified by icons on each bench.
The passengers must use the identified seats during travelling.
The seatbelts must be placed and fastened on both the seats facing the direction of travel and facing
away from the direction of travel.
Seats with a “red prohibition bar” icon must not be used while the vehicle is in motion.

equipped with three-point seat belt. OBLIGATORY USE OF SEAT BELTS
The equipment and appliances in the living
room of the motorcaravan may only be used
while the vehicle is standing still.
Their use during travel could violate the
applicable road traffic regulations and poses
risks the user must be aware of. No insurance
cover!
The manufacturer does not assume liability
for events or accidents that occur while
travelling.
When rearranging the seat cushions (especially when building the bed), make sure that both the
belts and the belt buckles are correctly positioned for the next journey.

RIGHTS AND DUTIES
Waste water can only be drained at dedicated locations like roadside service areas, waste disposal
stations or public and private sanitary facilities.
Attention: Public storm sewers must not be used for drainage as they are not designed to clean
waste water.
All water drain valves must be kept closed while driving.
Household waste must be collected in bags and disposed of at the dedicated facilities.
The application of all these principles strengthens mutual respect, respect for the environment and hospitality in the
regions visited.

WATER SYSTEM

Page | 13
1 – Water circuit
Waste water must only be drained at locations which are fully equipped for this purpose
(caravan parks, waste disposal stations, etc.).
2 – Drinking water supply
Your mobile home is equipped with a permanent fresh water tank with a capacity of 105 l.
It is located underneath the seat bench.

In winter, this tank remains free of ice as long as the motorcaravan is heated. It can be drained via a
manual drain valve.
The fresh water level sensor measures the amount of water inside the tank.
The control panel shows the filling level in percent.
The fresh water tank is filled by a hose without a connection piece via the plug on the front left side
of the vehicle. The tank is full when water runs through the overflow and drips down to the ground.
To make sure that the tank is not filled completely, check the filling level on the control panel in test
mode.
The fresh water tank must only be filled with potable water.
Before you open the stopcock and thus start the electric pump, you should check whether the tank
holds any water. Running without water may damage the pump.
Regardless of the source, depending on the filling system and the residual water in the tank, it cannot be
guaranteed that the water is potable.
The water in the tank loses its hygienic properties after a few days, even if additives are added. Drinking
the water or using it for cooking is not recommended. The water should be changed frequently. This can
be done at the lower right side. First, the tank must be cleaned with a disinfectant: the water in the fresh
water tank is not to be considered potable.
3 – Pump and filter
The electric power supply for the pump is switched on from
the control panel (see diagram). The pump supplies all water
and sanitary connections of the vehicle and starts when a
stopcock is opened.
The pump is located in the storage space of the front bench.
The pump filter is cleaned by your authorized dealer during
the vehicle inspection.

4 – Draining the fresh water
Turn off the power at the control panel.
Open the fresh water drain valve. The drain valve is located in the front storage space that can be
accessed through the flap under the table.
Open all taps to ensure complete drainage.
To finish the draining process, start the pump and let it run for
some time, keeping the taps open during this time.
5 – Hot water
Your vehicle is equipped with a TRUMA D4 unit, a heater with integrated
boiler, which is located in the rear box on the left side and powered with
diesel fuel (unless, however, the vehicle is equipped with a gas option).
The system draws water directly from the fresh water tank and supplies
various water extraction points (shower, wash basin, kitchen sink) with
hot water.
•Control panel
Press the rotary/pressure switch to activate the control panel.
- Scroll through the menu and select the hot water symbol .
- Scroll through the available setting options and select the
desired operating mode.
Boiler - the hot water supply is active
Eco - the hot water temperature is 40 °C
Hot - the hot water temperature is 60 °C
Boost - not available with Combi Diesel.
Press the rotary/pressure switch to confirm your selection.
Press the return button to exit the menu.

•Filling the boiler
The entire water supply system must be rinsed with clean water before first use.
Check whether the rotary knob of the drain valve (Frost Control),
which is located in the rear left-hand box, is in the “Operation”
position, i.e. parallel to the water connection, and whether it is
engaged. In order to close the drain valve, activate the pressure
switch until it locks into place.
Turn on the pump at the control panel.
Open the hot water taps in the kitchen and
bathroom. Leave the taps open until the air has
escaped from the system and the water runs as a
continuous stream from the taps.
If the temperature on the Frost Control is below 7°C, first start the heating system to warm up the
rebound space and the Frost Control. As long as the temperature at the Frost Control is above 7°C,
the drain valve can be closed.
•Draining the boiler
If the boiler is not used for an extended period of time, it must be emptied completely in order to
avoid frost damage.
Turn off the pump on the control panel and open all hot water taps.
Turn the rotary knob of the drain valve (Frost Control)
by 90° until it clicks into place. The pressure switch is
released from the engaged position and the drain valve
opens.

The water from the boiler is now drained outside via the drain valve. Place a container under the outlet
to ensure that the boiler has been completely emptied (about 10 litres).
If the temperatures drop below 3°C, the Frost Control safety/drain valve opens automatically and
empties the boiler.
Waste water can only be drained at dedicated locations like roadside service areas, waste disposal
stations or public and private sanitary facilities.
6 – Kitchen sink and wash basin
The kitchen sink and wash basin are made of plastic and must be cleaned with suitable household
products.
7 – Shower cubicle
The shower cubicle is equipped with a mixer tap. The sink must be cleaned
regularly with a suitable household product. Do not forget to secure the
shower head and the shower screen firmly in their holders before travelling.
The shower screen is foldable and secured with a strap.
During the use of the shower, the floor grid must be placed on the floor of
the shower cubicle and the shower curtain must be closed properly in order
to prevent water from escaping.

The shower head provided in your vehicle can be attached to the outlet
on the side of the left rear box and used as an outside shower.
8 — Draining
All waste water (from wash basin, kitchen sink and shower) is collected in a solid tank, which is
located under the vehicle.
A sensor checks whether the tank is full; this is displayed by this light on the control panel:
When the control light comes on, the tank must be emptied as soon as possible.
In order to drain the waste water tank, it is sufficient to pull the lever
on the left side of the vehicle near the rear wheel.
Waste water can only be drained at dedicated locations like roadside service areas, waste disposal
stations or public and private sanitary facilities.
For safety reasons and to maintain the warranty, changes of the water system must only be made
by authorised dealers with the written consent of Karmann-Mobil.
