Micro Filter
A micro filter (5) is arranged at the water inlet, the insert of which must be
checked before start-up and replaced whenever necessary.
If the machine is operated with polluted water or dirty filter inserts
heavy damage on the pump set and/or control elements will be the
result.
Frost Protection
Frost protection of the entire system is of vital interest in order to protect
the machine from heavy damage.
The best frost protection method is to store machine and accessories in a
permanently frost-protected area.
If frost is likely during storage or transport, frost protection to be carried out as
follows:
•
2 l of a 1 : 1 water/anti-freeze liquid (e. g. Glysantin) to be mixed in a
clean vessel. Dip water supply hose into the vessel and start pump.
•
Open spray pistol/stop valve and so return anti-freeze liquid into the
vessel, so circulating it through the system.
•
Open and close spray pistol/stop valve several times, in order to
also fill anti-freeze liquid into safety/control valve.
•
Machine is now protected against temperatures of approx. –30 °C.
Disregarding frost-protection instructions will result in heavy
damage of the machine.
Anti-freeze liquid always to be collected for re-use or to be
disposed according to environmental regulations!
