Safety behaviour and practices
If the gas system is leaking or if there is a
smell of gas
• extinguish all open flames
• open windows and door
• close all shut-off valves and gas cylinders
• do not smoke
• do not activate any electric switches
• ask an expert to inspect the entire system!
Ensuring a safe operating environment
• Suffocation through exhaust
gases. To ensure dissipation of exhaust gas-
es, operate the appliance outdoors only.
– Never use in enclosed spaces or tents or
breathe in the exhaust gases.
– If installing an awning, make sure that the
exhaust system terminates outdoors.
– If you park the RV in an enclosed space,
such as a garage or repair shop:
· You must block the fuel supply.
· You must switch the appliance off at the
control panel.
Consumer Safety Information • Keep the air inlet and exhaust outlet free
of obstructions in order to ensure clean
combustion.
• Do not place articles on or against the ap-
pliance. Do not lean any objects against
the water heater’s access door or place any
foreign objects within 61 cm (2 feet) of the
access door.
• Do not use or store flammable materials near
the appliance.
• Do not spray aerosols in the vicinity of the
appliance while it is in operation.
• Do not modify the appliance.
Responsibilities of the operator
• Avoid possible serious health issues caused
by electromagnetic radiation. All persons
with a pacemaker are prohibited from open-
ing the access door and maintaining the ap-
pliance during operation.
• The operator is responsible for the water
filled into the appliance and its quality.
• The use of upright gas cylinders from which
gas is taken in the gas phase is mandato-
ry for the operation of gas regulators, gas
equipment and gas systems. Gas cylinders
from which gas is taken in the liquid phase
(e. g. for forklifts) must not be used, since
they would result in damage to the gas
system.
• Gas systems and pressure regulators must
comply with the technical and administrative
regulations of the country in which the appli-
ance is used (AS/NZS 5601.2 – LP Gas instal-
lations in caravans and boats for non-propul-
sive purposes (“LP Gas installations”)).
• For your own safety it is absolutely neces-
sary to have the complete gas installation
regularly checked by an expert (at least every
2 years). The vehicle owner is always respon-
sible for arranging the gas inspection.

the RV. This disables all gas appliances and
pilot lights. Gas appliances must never be
operated while the vehicle is in motion.
• Shut OFF the appliance when refueling or
pumping gas, in multi-storey car parks, in
garages or on ferries.
• To avoid damage, make sure no spray water
enters the appliance when cleaning the RV,
e.g., do not spray directly into the openings/
ventilation grille.
Safe handling of malfunctions
• Switch OFF the gas supply and the appliance:
– if anything seems to be out of the ordinary.
– if you smell gas.
• Fire / explosion if you attempt
to use an appliance that has been damaged
by flooding or if the vehicle has been involved
in an accident. A damaged appliance must
be repaired by an expert or be replaced.
• Only carry out repairs yourself if the solution
is described in the troubleshooting guide of
this manual.
• A damaged appliance may have to be re-
placed with a new one.

6
Safe maintenance and repair
• Repairs may only be carried out by an expert.
• Children must not carry out maintenance,
repair or cleaning work.
• Before accessing terminals, please secure all
supply circuits (i.e. 12 V) and make sure that
the gas supply is securely turned off.
• Any work involving connection or intercon-
necting wiring must be carried out by a li-
censed electrician.
• Only use AquaGo decalcification tablets to
decalcify the appliance to avoid damage and
the voiding of your warranty.
– Never use vinegar.
– The use of non-Truma-approved substances
for decalcification can cause chemical re-
actions and produce hazardous substances
that could enter the drinking water.
• Any alteration to the appliance or its controls
can cause unforeseen serious hazards and
will void the warranty.
• After a long period of winterisation: Flush all
hot/cold water hoses and the appliance thor-
oughly with drinking water before using it.
• Keep the appliance free of foreign objects,
e.g., leaves, animals, spiderwebs, and keep
the area around free of snow and ice. The
appliance will not function properly if the in-
take air or exhaust terminal is obstructed.
Safety features
The appliance is equipped with the following safety devices:
Flame monitoring
If the flame goes out, the gas supply to the burner is switched
off (after 3 failed restarts).
Low-voltage (over-voltage) shutdown
If the voltage drops below 10 VDC (or rises above16.4 VDC),
the appliance shuts off.
Overcurrent protection
If there is a short circuit in the appliance (>10A), a fuse on
the control unit is activated and the appliance is switched off.
Monitoring of the flue fan
If there is a failure of the flue fan, the gas supply to the burner
is switched off.
Monitoring of hot water temperature
A water over temperature switch avoids excessively high wa-
ter temperatures in case of a malfunction.

Operating instructions
Read and follow the “Consumer Safety Instructions” be-
fore operating the appliance.
Scalding injuries caused by hot water!
Water temperatures over 52 ºC can cause severe burns or
scalding and in extreme cases even death.
• Before using the hot water tap or using the shower, allow
the hot water to run until the water temperature no longer
increases.
• Test the temperature of the water before placing a child in
the bath or shower.
• Do not leave a child or an infirm person in the bath
unsupervised.
How the appliance works
The appliance was developed exclusively for use in recreational
vehicles (RVs).
The appliance is connected between the vehicle’s fresh water
supply and its hot water system.
It is powered by propane and a 12 VDC power supply. The
ventilation grid on the access door allows combustion air to
flow into the appliance and exhaust gas to flow out.
When the appliance is switched on, the tap water will be
heated on-demand:
• A volume-flow sensor in the appliance detects when the hot
water tap has been opened and the volume flow is greater
than approximately 1.5 litres/min. The burner then starts
automatically.
• The burner control continously adjusts the heater output
based on volume flow and inlet water temperature, so that
the temperature at the hot water outlet is approximately
49°C. A temperature stabiliser is also installed in the appli-
ance to minimise fluctuations of the outlet temperature.
• After some time the maximum temperature at the tap or
in the shower is reached. The length of time will depend
on the model and variations in the water system (length of
pipes, insulation, circulation line, etc.). Like in a home show-
er, a comfortable water temperature at the shower head is
reached by mixing in cold water.
• When the volume flow is less than approximately
1.5 litres/min or the tap is closed, the burner is
automatically switched off.
The AquaGo is equipped with a circulation pump. The circula-
tion pump as well as the burner are switched on automatically
by the control unit in order to keep the water temperature
above 39 °C in “COMFORT” mode and 5°C in “ECO” mode.
Risk of damage in frost conditions.
Refer to “Operation in frost conditions” on Page11.
Pressure relief valve
Scalding injury from hot water and/or tampering with
the pressure relief valve!
• Never actuate the pressure relief valve as long as the ap-
pliance is still hot.
• Do not place a plug or reducing coupling on the outlet
part of the valve
The pressure relief valve is a safety component and must
not be removed for any reason other than replacement.
• The pressure relief valve is not serviceable; if defective, it
must be replaced. It must be replaced by a Truma certified
service technician.
Tampering with the pressure relief valve will void the warranty.

Operating procedures
Risk of damage in frost conditions.
In frost conditions, ambient temperatures below 4°C, there
is a risk that water in pipes, taps and appliances could
freeze. This can cause considerable damage.
• Before you fill water into appliances and parts that trans-
port water, you must heat the installation area sufficiently
so that the water cannot freeze.
Proceed as follows to fill the appliance with water:
1.Close open bypass lines (if present). Insert the water inlet fil-
ter or heating cartridge – if removed. See “Draining the wa-
ter and cleaning the water inlet filter” on Page13, steps
2, 7, 9 – 11.
2.Turn on fresh water supply or switch on water pump.
3.Fill the water system.
• Open all water-release points, e.g., cold and hot water
taps, showers, toilets.
It is important that you bleed the water system be-
fore starting the appliance.
– Once water flows continously, the water system is vented.
Close the water-release points.
Start the appliance as follows:
4.Make sure that the propane gas supply is turned on.
5.Switch on the 12 V power supply (RV).
6.Open the access door (refer to “Opening the access door”

Scalding injuries caused by hot water!
Water temperatures over 52 ºC can cause severe burns or
scalding and in extreme cases even death.
• Before using the hot water tap or using the shower, allow
the hot water to run until the water temperature no longer
increases.
• Test the temperature of the water before placing a child in
the bath or shower.
• Do not leave a child or an infirm person in the bath
unsupervised.
• There may be a variation between the temperature
delivered from the appliance and the temperature
at the tap due to water conditions or the length of
pipe from the appliance.
• The presence of a flow restrictor in the hot water
line may Iimit the water flow.
10. How to use hot water:
• To obtain the desired water temperature at the tap or in
the shower, mix cold and hot water.
• Particularly when showering, wait until the water tem-
perature has stabilised before entering or allowing other
people or animals to enter the shower.

Operation in frost conditions
(Ambient temperatures below 4°C)
Risk of damage in frost conditions.
In frost conditions, ambient temperatures below 4°C, there
is a risk that water in pipes, taps and appliances could freeze.
This can cause considerable damage.
• If the appliance is not to be used in frost conditions, you
must winterise the appliance. Refer to “Winterising the
appliance” on Page11.
• Winter operation will not protect the RV’s entire water
system. Water lines, taps, water tanks and the external
water valves and the vehicle must be heated separately.
• The RV must be designed for winter use/freezing
conditions.
• The water pipes in the RV must be ice-free to operate the
AquaGo in winter. Otherwise, there is no water flow and
the appliance does not start.
When the vehicle is standing, to -20°C
• The appliance has a built-in thermostat that will start the
burner and the circulation pump whenever the temperature
in the appliance falls below +5°C. The burner will automati-
cally shut off when it senses a temperature above 44°C.
• For the appliance to operate properly, you
must ensure a constant supply of power (12 V), propane
gas, sufficient water in the system. You must leave the ap-
pliance powered “ON”. The operating mode must be “ECO”
or “COMFORT”. The water system must be bled so that the
circulation pump works.
• If the vehicle is standing and ambient tempera-
tures are below -20°C, the appliance must not be operated
and must be winterised. To winterise the appliance (refer to
“Winterising” on Page11).
While driving (or if there is no gas supply), to -20 °C
• Gas must not be used for heating while the ve-
hicle is in motion. Ask your dealer / vehicle manufacturer
about options for heating your RV while driving.
• An electric antifreeze kit is available as an accessory (ask
your dealer). With this kit, the appliance can be kept frost-
free while you are driving or if there is no gas supply (to
ambient temperatures of -20 °C). The electric antifreeze kit
includes detailed instructions.
– While the vehicle is in motion and at ambi-
ent temperatures below -20 °C the appliance must not be
operated and must be winterised. To winterise the appli-
ance (refer to “Winterising” on Page11).
Winterising
Severe damage to the water system components and
the appliance!
Any damage caused by freezing or an unsuitable winteris-
ing fluid will not be covered by warranty.
• Follow the recommendations below if the appliance will
be stored under freezing conditions or for an extended
period of time.
• Winterise the appliance at the start of the winter season
or before travelling to a location where freezing conditions
are likely.
If your RV is equipped with a bypass around the appliance,
separate the appliance from the water system with the
bypass.
Winterising the appliance
To winterise the appliance, you must drain all water from the
appliance. To do this we advise the following steps:
• Remove the water inlet filter or heating cartridge. See
“Draining the water and cleaning the water inlet filter” on
Page13, steps 1to 8.
• Let water completely drain from the appliance. This can
take several minutes.
• Do not insert the water inlet filter or heating cartridge into
the appliance during winter – if the appliance is not used.
• Danger of crushing/pinching of fin-
gers when the Easy Drain Lever is closed! Never put
fingers between the Easy Drain Lever and latch.
• Close the Easy Drain Lever and the access door.
Once the water has been drained, the appliance is protected
against freezing conditions.
Winterising the RV with a winterising fluid
• Winterising the RV with a winterising fluid is only
possible with an installed bypass kit (not in scope
of delivery)

Maintenance
Repairs must be performed by a certified service technician.
Truma recommends that the appliance be serviced annually
by a certified service technician. Verify proper operation after
servicing.
High temperatures or repair attempts while the gas
supply is turned on may result in scalding injuries!
• Turn OFF the electrical power supply and the gas supply
before starting maintenance and repair work.
• Allow the appliance to cool down.
• Never actuate the pressure relief valve as long as the ap-
pliance is still hot.
Injuries caused by the Easy Drain Lever!
• Never actuate the Easy Drain Lever as long as the appli-
ance is under water pressure and/or is still hot.
Sharp edges can cause cuts and injury!
• Always wear protective gloves to avoid injuries from
sharp edges during maintenance work.
Draining the water and cleaning the water
inlet filter
To keep the appliance fully functional, clean the water
inlet filter at least once a year.
1. Set the control panel to “Off“.
2. Remove the access door (refer to “Removing the access door”
on Page8.)
3.Switch OFF the appliance at the POWER switch.
4.Open all hot water taps and wait for cold water. This will
ensure that hot water is removed from the appliance before
draining.
5.Turn OFF the water supply or switch OFF the water pump.
6.Leave the hot water tap open in order to depressurise and
vent the water system.
Injuries caused by the Easy Drain Lever!
When the Easy Drain Lever is folded out, it protrudes beyond
the side wall of the vehicle.

Decalcification
Risk of damage in frost conditions.
In frost conditions, ambient temperatures below 4°C, there
is a risk that water in pipes, taps and appliances could
freeze. This can cause considerable damage.
• Do not decalcify the appliance in frost conditions.
Decalcification frequency
Lime scale occurs especially as a result of precipitation from
“hard” water. The appliance must be decalcified regularly de-
pending on water hardness and hot water consumption.
Recommended decalcification frequency per year

Use low* normal* high*
* Hot water consumption
low –> approximately 2400 l /Year
normal –> approximately 6000 l /Year
high –> approximately 24000 l /Year
Performing decalcification
An integrated water consumption meter recognises (after hot
water consumption of approx. 6000 l) that decalcification is
necessary. The assumed water hardness is “hard” and can-
not be changed. The yellow status LED3 (Fig. 9) indicates
that decalcification is necessary (goes off briefly about every
7seconds).
The use of non original AquaGo decalcification tablets
(e.g. vinegar) for decalcification can cause chemical
reactions and produce hazardous substances that
could enter the drinking water supply.
• Do not mix AquaGo decalcification tablets with other
substances to avoid chemical reactions and production of
hazardous substances.
• Use only AquaGo decalcification tablets to decalcify the
appliance to avoid:
– chemical reactions and production of hazardous
substances,
– damage to your appliance,
– and the voiding of your warranty.
– Call your local AquaGo dealer or service provider or see
www.truma.com for more information to obtain
AquaGo decalcification tablets.
Irritation of skin and eyes in case of contact with de-
calcification agent
Wear protective gloves, eye protection and face protection
to avoid contact.
• Never use the water supply in the RV during decalcification
• In case of skin contact with the decalcification agent, im-
mediately rinse the affected area with plenty of water.
• In case of eye contact, hold eyelid open and rinse with
running water for 10 – 15 min. Remove contact lenses, if
present and easy to do. Continue rinsing. Consult an eye
specialist.
• If you swallow the decalcification agent, immediately
rinse your mouth and drink plenty of water in small sips.
Do not vomit. Consult a doctor.
During decalcification, you must also observe the
following
• Damage to the appliance if decalcification is interrupted.
– You must complete the decalcification process and then
rinse thoroughly with clean water.
– Allow about 3 hours for decalcification. The appliance
works on its own for most of this time.
• Sensitive surfaces (e. g. marble) may be damaged through
contact with the decalcification agent.
– Immediately remove splashes of decalcification agent on
these surfaces.
a) Preparing for decalcification
For safety reasons, once the decalcification process has
started it must not be stopped until the system has been
rinsed (see process f). All operating modes of the appliance
are blocked until decalcification has been completed.
Tasks within the RV
• Set the control panel to “Off”.
• Turn OFF the water supply or switch OFF the water
pump.
• Open a hot water tap to relieve pressure in the system.
• On all water taps attach the warning sign “Caution decal-
cification in progress” in a clearly visible position. Warn-
ing signs are enclosed with the decalcification tablets.

• Make sure that the operating pressure of the gas supply
corresponds to the operating pressure of the appliance
2.62 – 3.49 kPa.
For correct installation, you must also observe the
following:
• The gas connection (SAE 45° Flare Male – SAE J512,
5/8 inch – 18) is located inside the appliance.
• Make sure that the gas line to the appliance is able to sup-
ply the maximum required quantity of gas 61.9 MJ/h, with-
out the gas pressure on the gas connector of the appliance
falling below 2.62 kPa.
• Consider the space needed to lay the gas line and integrate
the appliance when planning the installation space.
• Guide the gas line into the installation space so that the ap-
pliance may be removed and reinstalled if service or repairs
are needed.
• Allow sufficient length and flexibility in the gas line for con-
nection or disconnection of the gas line.
• Reduce the number of separation points in the gas line to
the technically required number.
• Avoid separation points in the gas line in spaces used by
people.
• Ensure that the gas connection from the vehicle is in place
before installing the appliance.
– Gas side connection
Risk of explosion due to improper installation of the
gas side connection!
• Use rigid metal 3/8 inch pipes (corresponds to 1/2 inch
(12.7 mm) outside diameter) for the side gas connector of
the appliance to the gas system of the RV.
• In exceptions, flexible gas hoses may be used for the side
gas connector. The following 4 conditions must be met:
1.Guidelines, laws or regulations allow the use of flexible
gas hoses in this application.
2.The flexible gas hoses are certified for this type of
application.
3.The flexible gas hoses can be inspected easily over their
entire length.
