13.1.7 FrostControl (safety / drain valve)
The safety / drain valve is near the heater.
"FrostControl" (Fig. 72/1) is a currentless safety/drain valve. When there is a danger of frost, it
automatically drains the contents of the boiler through a draining socket (Fig. 72/4). If exces-
sive pressure is present in the system, pressure will be automatically intermittently equalised
through the pressure relief valve.
Closing the drain valve:
Check if the rotary switch (Fig. 72/2) is set to "Operation" (parallel to the water connec-
tion (Fig. 72/3) and is engaged..
It can be manually closed with the snap button (Fig. 72/5) (pressed) and then the boiler
filled only when the temperature at the drain valve is above approx. 7 °C.
Set the heater to summer or winter mode (Chapter 13.1.2 or 13.1.3) and set the rotary
switch (Fig. 72/2) of the valve (Fig. 72/1) to "Operation". The rotary switch must engage.
Press the snap button (Fig. 72/5) into the valve until it engages ("closed" position).
Always keep the drainage pipe (Fig. 72/4) of the safety / drain valve free from contami-
nation (slush, ice, leaves, etc.).
Automatic opening of the drain valve:
When the temperature at the drain valve is below approx. 3 °C, the drain valve will open auto-
matically, the snap button (Fig. 72/5) springs out and the supply of water of the motorhome
drains out through the drainage pipe (Fig. 72/4).
Manual opening of the drain valve:
Turn the rotary switch (Fig. 72/2) 180° until it eng ages.
The snap button (Fig. 72/5) springs out and the water drains out through the draining
socket (Fig. 72/4).
