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 a fault.
Operating Instructions
Read and follow the “Consumer Safety Information” before operating the appliance.
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 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 detects 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 continuously 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 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 approximately 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 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 102 °F (39 °C) in “COMFORT” mode and 41 °F (5 °C) in “ECO” mode.
Risk of damage in frost conditions. Refer to “Operation in frost conditions”.
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.
