Truma AquaGo™ instant water heater or its
controls can cause unforeseen serious hazards and will void the warranty.
Operating Instructions
Read and follow the “Consumer Safety Information” before operating the
Truma AquaGo™ instant water heater.
Scalding injuries caused by hot water!
Water temperatures over 127ºF (52ºC) can
cause severe burns or scalding and in extreme
cases even death.
• Before using hot water faucet 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.
• After a long period of winterization:
Flush all hot/cold water hoses and the
Truma AquaGo™ instant water heater thoroughly with drinking water before using it.
Safety features
The Truma AquaGo™ instant water heater is
equipped with the following safety devices:
Flame monitoring
If the flame goes out, the gas supply is switched
off.
Low-voltage shutdown
If the voltage drops below 10 V DC, the gas
supply to the burner is switched off.
Overcurrent protection
If there is a short circuit in the Truma
AquaGo™ instant water heater (>10A), a
fuse on the control unit is activated and the
Truma AquaGo™ instant water heater 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.
How the Truma AquaGo™
instant water heater works
The Truma AquaGo™ instant water heater was
developed exclusively for use in Recreational
Vehicles (RVs).
The Truma AquaGo™ instant water heater is
connected between the vehicle’s fresh water
supply and its hot water plumbing system.
It is powered by propane and a 12 V power supply. The ventilation grid on the access door allows combustion air to flow into the appliance
and exhaust gas to flow out.
The water pressure on the inlet side must be
limited to 65 psi (4.5 bar), if necessary with a
water pressure regulator.
When the Truma AquaGo™ instant water heater
is switched on, the tap water will be warmed
on-demand:
• A volume-flow sensor in the Truma
AquaGo™ instant water heater detects
when the hot water faucet has been opened
and the volume flow is greater than approximately 0.4gallons/min (1.5 liter/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 120°F (49°C). A temperature stabilizer is also installed in the
Truma AquaGo™ instant water heater
to minimize fluctuations of the outlet
temperature.
5
• After some time the maximum temperature
4a
at the faucet 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 plumbing (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 0.4 gallons/min (1.5 liter/min) and the
faucet is closed, the burner is automatically
switched back off.
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 Truma AquaGo™ instant water
heater is still hot.
• Do not place a plug or reducing coupling on
the outlet part of the valve.
The AquaGo™ comfort and AquaGo™
comfortplus 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 a certain level (102°F (39°C)
in “Comfort” mode and 41°F (5°C) in “ECO”
mode).
The AquaGo™ comfort and AquaGo ™
comfortplus models permit operation without
the risk of freezing even at temperatures of
-4°F(-20°C).
• Only the Truma AquaGo™ instant water
heater will be protected from freezing. Cold
water lines, the water tank and the external
water valves may freeze. The vehicle must
be heated separately.
A constant supply of power (12 V), propane
gas, and water is needed during low-temperature operation.
To conserve gas and power, use the
“ECOON” switch position. This will maintain a temperature above 41°F (5°C) in the
Truma AquaGo™ instant water heater. For
maximum comfort (rapid availability of hot water at the faucet), use the “ON Comfort” switch
position. This will maintain a temperature above
102°F (39°C) in the appliance.
• The pressure relief valve is a safety component and shall not be removed for any reason other than replacement.
• The pressure relief valve is not serviceable; if
defective it must be replaced. Replacement
shall be performed by a certified service
technician.
• Tampering with the pressure relief valve will
void the warranty.
The Truma AquaGo™ instant water heater is
equipped with a pressure relief valve (Fig. 3)
that complies with the standard for Relief Valves
for Hot Water Supply Systems, ANSI Z21.22
