Draining the water container
To make sure that all water drains properly from the water container, place a big enough
vessel underneath the drainage socket of the pressure relief/drain valve (> 2.64 gallons (10
liters).
Use the main switch or pump switch to switch off the power to the water-pump
assembly.
Turn off or disconnect the city water connection, if present.
Open all water release points, e.g. cold and hot water faucets, showers, toilets.
Open the pressure relief/drain valve
The water container will drain via the drainage socket of the pressure relief/drain valve.
Decalcifying and cleaning the water container
1.
For decalcifying the water container, fill the water container with citric acid and let it
work for some time.
2. Fill citric acid into the fresh water supply and dilute it with fresh water according to the
supplier’s specification.
3.
Add more than 2.64 gallons (10 liters) of water to fill up the water container of the
Combi furnace.
4. Drain the mixture of citric acid and water from the water container (refer to “Draining
the water container”) and flush it with fresh water (refer to “Filling the water con
-
tainer”).
5. In order to avoid growth of micro-organisms, regularly heat the water in the boiler to
158 °F (70 °C) as follows:
a. Select energy mode “LP gas” on CP plus control panel.
b. Select the hot water level “boost” on CP plus control panel.
c.
When the water temperature is reached (the display does not flash anymore), leave
the heating switched on for another 30 minutes without withdrawing water from
the system. The residual heat in the device will heat the water to up to 158 °F (70
°C).
Damage to the Combi furnace caused by freezing!
The Combi furnace does not have a frost-protection function. The water
container must be drained if the recreation vehicle will not be used when-
ever there is a risk of frost.
No warranty claims are accepted by the manufacturer of the Combi fur-
nace for frost/freeze damage
NOTE:
Truma recommends decalcifying and cleaning the water con
-
tainer at least twice a year for hygienic reasons. Only use specialized and
suitable products. Do not use chlorine-based products. Read and follow
the instructions of the decalcifying agent’s manufacturer.
