General safety notes
The use of upright gas cylinders from which gas is taken in
the gas phase is mandatory for the operation of gas regula-
tors, gas equipment and gas systems. Gas cylinders from which
gas is taken in the liquid phase (e. g. for fork lifts) must not be
used, since they would result in damage to the gas system.
In event of leaks in the gas system or if there is a smell of gas:
– extinguish all naked flames
– do not smoke
– switch off all appliances
– shut off the gas cylinder
– open the windows and doors
– do not actuate any electrical switches
– have the entire system checked by an expert!
Repairs may only be carried out by an expert.
– This device is not designed to be used by persons (including
children) with limited physical, sensory or mental capacities
or persons lacking in experience or know-how, unless they
are supervised by somebody responsible for their safety or
unless they have received instruction about how to use the
device.
– Children should be supervised to ensure they do not play
with the device.
– To avoid the risk of accidental resetting of the over-temper-
ature guard, the device may not be supplied with power via
an external contactor, such as e.g. a timer, nor may it be
connected to a power circuit that is regularly switched on or
off via a device.
Danger
Failure to operate the relief valve easing gear at least once
every six months may result in the water heater splitting.
Continuous leakage of water from the valve may indicate a
problem with the water heater!
– Water may drip from the discharge pipe of the pressure
relief device and this pipe must be left open to the
atmosphere.
– The pres sure relief device is to be operated regularly to
remove lime deposits and to verify that it is not blocked.
– Any discharge pipe connected to the safety (pressure relief)
valve is to be installed in a continuously downward direction
and in a frost free ambient.
– Before gaining access to any and all terminals, please en-
sure all supply circuits are disconnected (i.e. 230 – 240 V
and 12 V) and gas supply is securely turned off.
– Any work involving connection or interconnecting wiring
must be conducted by a licensed electrician.
– Any modifications to the unit, including accessories and
cowl, or the use of spare parts and accessories that are im-
portant to the operation of the system that are not original
Truma parts and failure to follow the installation and oper-
ating instructions will cancel the warranty and indemnify
Truma from any liability claims. It also becomes illegal to
use the appliance, and in some countries this even makes it
illegal to use the vehicle.
– The operating pressure for the gas supply is 2.75 kPa
(AUS – Propane, NZ – LPG) and must correspond to the op-
erating pressure of the appliance (see data plate).
– LPG Systems and pressure regulators must comply with
the technical and administrative regulations of the country
in which the appliance is used. For your own safety it is
absolutely necessary to have the complete gas installation
regularly checked by an expert (at least every 2 years).
The vehicle owner is always responsible for arranging the
gas inspection.
– Do not operate when travelling.
– Do not operate the water heater when refuelling the vehicle
and when in the garage.
– Items sensitive to heat (e. g. spray cans) must not be stored
in the installation area, since excess temperatures may un-
der circumstances be incurred there.
– During the initial operation of a brand new appliance (or
after it has not been used for some time), a slight amount of
fumes and a slight smell may be noticed for a short while.

Draining the water heater
If the mobile home is not used during periods of frost,
it is essential that the Boiler be emptied.
1. Disconnect power for water pump (main switch or pump
switch).
2. Open hot water taps in bathroom and kitchen.
3. Open safety/drain valve: Lever in vertical position, position (f).
4. The water heater is now drained directly to the outside via
the drain valve. Check that the water contents have been
completely drained (10 litres or 14 litres).

Never operate the water heater without water in it!
If the wall cowl is positioned close to an opening window (or
hatch) – in particular directly under it – it must remain closed
when the water heater is in use (see warning plate).
1. Remove cowl cover.
2. Open gas cylinder and open stop cock valve in the gas
supply line.
3. Switch on water heater at the switch on the control panel (b).
When using the vehicle switches
Refer to operating instructions of the vehicle manufacturer or
see switch labels.
4. If there is air in the gas supply line, it may take up to a min-
ute before the gas is available for combustion. If the
appliance switches to “Failure” during this period, switch off
the appliance – wait 10 minutes – and switch on again!
Switching off gas operation
Switch off the water heater to position (c).
Fig.4
If the water heater is not to be used for a longer period,
mount cowl cover (non-observance of this point can lead to
the function of the appliance being impaired through water,
dirt or insects), close stop cock valve in the gas supply line
and close the gas cylinder.
Before setting off on any journey, fit cowl cap with the
boiler switched off. Please ensure that it is secure and
has locked into place (risk of accident). Defective cowl caps
must not be used.
Always observe the operating instructions prior to
starting! The vehicle owner is responsible for the correct
operation of the appliance.
The installer or vehicle owner must apply the yellow sticker
with the warning information, which is enclosed with the ap-
pliance, to a place in the vehicle where it is clearly visible to
all users (e. g. on the wardrobe door)! Ask Truma to send you
stickers, if necessary.
Before using the first time, it is essential to flush the
entire water supply through with clean warm water.
Always mount the cowl cap when the water heater is not be-
ing operated! Drain the water heater if there is a risk of frost!
There shall be no claims under guarantee for damage
caused by frost!
Always remove the cowl cover prior to operating the
water heater!
If connecting to a central water supply (rural or city connection)
or when using more powerful pumps, a pressure reducer
must be used which prevents pressures of greater than
400 kPa occurring in the Boiler.
Filling the Truma Boiler with water
1. Check that the drain valve in the cold water intake is
closed: Lever should be in horizontal position, position (e).
f e
e
Fig. 2
e = Lever position “Closed”
f = Lever position “Drain”
2. Open hot tap in bathroom or kitchen, with pre-selecting
mixing taps or single-lever fittings set to “hot”.
3. Switch on power for water pump (main switch or pump
switch).
Leave the tap open to let air escape while the water heater is
filling. The heater is filled when water flows out of the tap.
Residues of frozen water can prevent filling if there is a frost.
The water heater can be defrosted by switching on the heater
for a short period (max. 2 minutes). Frozen pipes can be de-
frosted by heating the room.
If just the cold water system is being used, without
water heater, the heater tank is also filled up with water.
In order to avoid damage through frost, the water contents
must be drained by actuating the drain valve, also when the
heater has not been used. As an alternative, two shut-off
valves, resistant to hot water, can be fitted in front of the cold
and hot water connection.

Frequently asked questions
To drain the water heater, disconnect power for the water pump, open hot water taps, and open the safety/drain valve. The water heater will drain directly to the outside via the drain valve. Check that the water contents have been completely drained (10 liters or 14 liters).
The operating pressure for the gas supply is 2.75 kPa (AUS – Propane, NZ – LPG).
Always remove the cowl cover before operating the water heater. Open the gas cylinder and the stop cock valve in the gas supply line. Switch on the water heater at the switch on the control panel.
The red indicator lamp lights up if there is a failure. To unlock, switch off the appliance, wait 10 minutes, and switch on again.
To operate the electrical heating element, insert the plug into the socket and then turn it on with the switch. The electric heating element is operational when you can see the mark on the switch.
