Keep the taps open until the water flowing out of the taps has no bubbles
in it. This is the only way to ensure that the boiler is full of water.
Close all water taps.
Emptying the boiler:
Set the rotary switch (Fig. 212,2) on the operating unit (Fig. 212) to " ".
Open the safety/drainage valve. To do this turn the knob (Fig. 213,1) par-
allel to the safety/drainage valve. The push button (Fig. 213,2) jumps out.
The boiler is drained to the outside by the safety/drainage valve.
Check whether the water has been drained completely from the boiler
(approx. 12 litres).
9.4.3 Truma Combi boiler D
The boiler is integrated in the heater and is powered with diesel fuel from the
fuel tank. The boiler is switched on by turning the rotary switch (Fig. 215,2) on
the operating unit (Fig. 215).
In winter operation "Heater and boiler" (Fig. 215,3) the water is automatically
heated up when the heater is switched on. If the heater switches off after the
required room temperature has been reached, the boiler will continue to heat
up until the set water temperature has been reached.
In summer operation (Fig. 215,1) only the water in the boiler is heated up to
either 40 °C or 60 °C. The water is heated to 60 °C in approx. 25 minutes. The
yellow indicator lamp (Fig. 215,4) illuminates during the boiler heating-up
period.
The power supply for the appliance cannot be interrupted by means of the
12 V main switch. When there is a fault, the red indicator lamp (Fig. 215,4) on
the operating unit illuminates (see chapter 14).
Safety/drainage valve The boiler is equipped with a safety/drainage valve (Fig. 216). The safety/
drainage valve prevents water in the boiler from freezing, when there is frost
and the heater is not switched on.
Z Further information can be obtained in the manufacturer's instruction
manual.
X Take the device out of operation by removing the fuse and contact cus-
tomer service if one of the following events occurs: Long lasting, strong
development of smoke; unusual combustion noises; smell of fuel; con-
tinuous fault shut-down with error message (blink code).
