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

• 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 open­ing the access door and maintaining the ap­pliance 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 mandato­ry 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 appli­ance is used (AS/NZS 5601).

•
gases. To ensure dissipation of exhaust gas­es, 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 to the 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.

• Keep the air inlet and exhaust outlet free
of obstructions in order to ensure clean
combustion.

4

Suffocation through exhaust

• 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.

Safe operation

• Use with propane gas only. Butane or any
mixtures containing more than 10% butane
must not be used.

• The nominal gas system pressure must be

2.75 kPa.

• LP tanks must be filled by a qualified gas
supplier only.

• Hot water can be dangerous, especially for
infants, children, the elderly or infirm. It can
cause severe burns. Therefore:

– Never actuate the pressure reliefvalve

(Fig.1 – 4 ) as long as the appliance is still
hot.

– Never actuate the Easy Drain Lever

(Fig. 1 – 11) as long as the appliance is un­der water pressure and/or still hot.

• Always check the water temperature before
entering a shower or bath.

• The water pressure on the inlet side must be
limited to 450 kPa, otherwise internal com­ponents of the appliance will be damaged.
On (city) water connections with a pressure
higher than 450 kPa a pressure regulator is
strongly recommended.

While driving

• To avoid damage, make sure the access door
(Fig. 1 – 20) to the appliance is closed before
moving the RV, as follows:

– Turn lock is engaged.
– Access door is flush with the cover plate.

• Shut OFF gas and the LP tank when moving
the RV. This disables all gas appliances and
pilot lights. Gas appliances must never be
operated while 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/
venting grid.

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 re­placed with a new one.

Safe maintenance and repair

Safety features

• 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 intercon­necting wiring must be carried out by a li­censed electrician.

• Only use Truma 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 re­actions and produce hazardous substances
that could enter the drinking water.

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 wa­ter temperatures in case of an error.

• 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 thor­oughly 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 in­take air or exhaust terminal is obstructed.

Operating instructions

Read and follow the “Consumer Safety Instructions” be­fore operating the appliance.

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 ap­pliance is still hot.

• Do not place a plug or reducing coupling on the outlet
part of the valve

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 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 certified service
technician.

Tampering with the pressure relief valve will void the warranty.

4a Test lever

• 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 appli­ance 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 (AquaGo™ basic, AquaGo™ comfort and
AquaGo™ comfort plus) and variations in the water system
(length of pipes, insulation, circulation line, etc.).
Like in a home shower, 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™ comfort and AquaGo™ comfortplus
models are equipped with a circulation pump. The circulation

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 frosty conditions.

Decalcification

Risk of damage in frosty conditions.

In frosty conditions there is a risk that water in pipes, taps and
appliances could freeze. This can cause considerable damage.

• Do not decalcify the appliance in frosty conditions.

The use of non original Truma 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 Truma AquaGo™ decalcification tablets with
other substances to avoid chemical reactions and produc­tion of hazardous substances.

Decalcification frequency

Lime scale occurs especially as a result of precipitation from
“hard” water. The appliance must be decalcified regularly de­pending on water hardness and hot water consumption.

The exhaust over temperature switch (EOS) or burner over temperature
switch (BOS) is open/unplugged.

The EPS did not close when the flue fan was actuated because the fan
did not push enough air through the exhaust channel. A cause could be,
e.g., blocking of the exhaust channel or a faulty switch.
OR
The EPS is closed even though the flue fan is not running. Cause is a de­fective EPS or flue fan.

The WOS opened at a water temperature of over 85°C.

There is an error in flame detection of the burner because the flame was de­tected
– before ignition or
– before the release of gas or
– after the gas was switched off.

There is a heating request but gas cannot be released.

APPENDIX E – Notes for painting the access door and cover plate

Important Information

Observe all safety notes/instructions for painting the ac-

cess door and cover plate.

The following parts (see Fig. 38) may be painted:

• The white cover plate

• The white outer surfaces of the access door

Material of the parts:

• The parts are made from a polycarbonate material.

• Check whether the paint to be used is suitable for
polycarbonate.

• For optimum adhesion of the paint it may be necessary to
apply a primer to the surfaces that will be painted.

•
the parts. Follow the recommendations of the paint
manufacturer.

The following parts (see Fig. 37) must not be painted:

• The black venting grid

• The turn lock

• The webbings

Use of unsuitable paints may damage

Work after painting

7. Remove all masking.

8. Assemble the venting grid and the turn lock in the reverse
order. Make sure that they are installed in the right
direction.

9. Ensure turn lock operates correctly (if unsure: see “Closing
the access door” on Page8).

Painting a detached access door

If necessary for masking or painting, the access door
can be detached temporarily.

• Remove the four (4) screws that fix the webbings.

• Fix the webbings again after painting.

Danger of personal injury or damage to the recrea­tional vehicle.

Unsecured webbings cause the access door to become
loose and it may fall off when you are driving the RV.

• After painting, the webbings must be fixed firmly to the
access door with the original screws.

Work before painting

In order to simplify painting and reduce the work for
masking, the turn lock and the venting grid can be

removed/disassembled.

Please follow the steps below to remove the venting
grid and the turn lock:

1. Open the access door.

2. Remove the venting grid:

• Using a Torx T-15 remove the 4 screws securing the
venting grid to the access door.

• After removing the screws, depress the four (4) clips on
the side of the venting grid and remove it as shown in
Fig. 37.

3. Remove the turn lock:
To remove the turn lock, depress the four (4) clips and
remove it as shown in Fig. 37.

4. Mask the venting grid opening from the back side (side with
waffle pattern).

5. Close the access door and fix it in the closed position for
painting.

• This can be done with help of tape that joins the flue fan

and the edge of the turn lock opening (see Fig. 38 for this
detail).

• Remove any tape that hangs over the edge by more

than 3 mm.

• Finally mask the turn lock opening with tape (hatched

area). Take care not to exceed 3 mm from the edge (this is
the area that will be covered by the turn lock).

6. Paint the access door and the cover plate.
