vessel. Put water supply hose into the vessel and start the high pressure
pump.
•
Spray pistol/stop valve to be opened in order to circulate the anti-freeze
liquid.
•
Spray pistol/stop valve to be opened and closed several times in order to
also fill safety/control valve with anti-freeze liquid.
•
Stop high pressure pump and disconnect all hoses.
•
Machine is now protected against temperatures of –30 °C.
Disregarding of frost-protection instructions can cause severe
damage on the entire system.
Anti-freeze liquid to be collected for re-use, respectively to be
dumped properly according to safety regulations.
