2.8 Protecting the water circuit against ice

In order to avoid any damage that could be caused by
frost, it is necessary to empty water tanks, pumps and
hoses when winter is coming.
1. Only allow a minimal amount of water to remain in the
tanks. (The yellow signal lamp of the water level gauge is
on). (Picture 1)
2. Using the water filling opening, add an anti-freeze
solution in sufficient quantity to the water circuit to
protect it against ice. (Picture 2)
3. Turn on the damping pump and the high-pressure pump
(if the option is available) in order to make the anti-freeze
solution circulate through the hoses and the pumps.
(Pictures 1 + 3)
4. Unscrew the drain plug or the inlet filter, to drain the
tanks and the hoses. (Picture 4)
