Read and follow the “Consumer Safety In-
formation” before operating the appliance.
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 the 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.
How the appliance works
The appliance was developed exclusively for use
in recreational vehicles (RVs).
The appliance is connected between the ve-
hicle’s fresh water supply and its hot water
plumbing system.
It is powered by propane and a 12 V power
supply. The ventilation grille 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 water
will be heated on demand:
• A volume-flow sensor in the appliance de-
tects when the hot water faucet has been
opened and the volume flow is greater than
approximately 0.4 gallons/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 tempera-
ture at the hot water outlet is approximately
120 °F (49 °C). A temperature stabilizer is
also installed in the appliance to minimize
fluctuations of the outlet temperature.
• After some time the maximum temperature
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 approxi-
mately 0.4 gallons/min (1.5 liter/min) and the
faucet is closed, the burner is automatically
switched off.
The AquaGo comfort and AquaGo
comfort plus models
are equipped with a cir-
culation pump. The circulation pump as well as
the burner are switched on automatically by the
control unit in order to keep the water tempera-
ture above 102 °F (39 °C) in “COMFORT” mode
and 41 °F (5 °C) in “ECO” mode.
