Operating instructions

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

WARNING 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 liters/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 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 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 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 is 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.
  NOTICE Risk of damage in frost conditions.
  Refer to “Operation in frost conditions” on Page 11.

Pressure relief valve

WARNING 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
  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.

Decalcification

Risk of damage in frost conditions.
In frost conditions, with 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
  Limescale occurs especially as a result of precipitation from “hard” water. The appliance must be decalcified regularly depending on water hardness and hot water consumption.

Recommended decalcification frequency per year

Water hardness mg/l CaCO 3| Very hard >180| 1| 2| 4
---|---|---|---|---
Hard 121 – 180| 1| **1| 3
Moderately hard 61 – 120| 1| 1| 2
Soft 0 – 60| ****1| ****1| 1
| 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 recognizes (after hot water consumption of approx. 6000 l) that decalcification is necessary. The assumed water hardness is “hard” and cannot be changed. The yellow status LED 3  (Fig. 9) indicates that decalcification is necessary (goes off briefly about every 7 seconds).

WARNING The use of nonoriginal 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 the 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 decalcification 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, immediately 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.

  – Open all water-release points, e.g., hot water taps, showers, toilets .
  – Once water flows evenly, the water system is vented.
  – Close the water-release points.

• Before you use the water system and the appliance, check the colour of the water at all taps:
  – Slightly red –> rinse again.
  – Clear –> decalcification is finished.

• Remove the warning signs “Caution decalcification in progress”.

Interrupting decalcification
Decalcification is indicated through slow flashing (1 s on, 1 s off) of the status LED 3 (Fig. 9) on the control panel.

• Decalcification can be interrupted by switching the control panel to “Off”.
  – Decalcification is interrupted after about 2 s.
  – The status LED 3 (Fig. 9) on the control panel flashes quickly.

• WARNING Irritation of skin and eyes in case of contact with decalcification agent. Wear protective gloves, eye protection and face protection to avoid contact.

• First you must take out the water inlet filter and remove any AquaGo decalcification tablets that it may contain.
  – To take out the water inlet filter, refer to “Draining the water and cleaning the water inlet filter” on Page 12.
  – Dispose of AquaGo decalcification tablets in accordance with local laws and regulations.
