Frost Protection
Frost protection of the entire water system during storage and transport
is a must, as otherwise heavy damage on the system and severe
dangers during operation may occur.
The best frost protection is to store the machine and accessories in a frost-
protected room.
If frost is likely during storage and/or transportation the machine to be
protected as described below:
Mix 2 Liters of a 1 : 1 water/anti-freeze liquid (e.g. Glysantin) in a clean
vessel, dip water connecting hose into anti-freeze liquid and start pump
by pressing motor protection switch and red frost protection switch on
the right side of electric box simultaneously.
Open spray pistol and return drawn-off anti-freeze liquid into the vessel,
so allowing the liquid to circulate through the system. The frost
protection switch (15) to be kept pressed during the procedure.
Spray pistol to be opened and closed several times in order to fill
unloader valve and pressure gauge with anti-freeze liquid.
Stop pump, release frost protection switch and disconnect all hoses.
Machine is now protected against frost to
–30 °C.
Disregarding frost protection instructions will result in heavy
damage of the water carrying components.
Never simply dump anti-freeze liquid but collect it for re-use or
dispose according to environmental regulations.
