Technical data

Pre-Filter (micro filter 25/50 µm)
Upstreams of the high pressure pump there is a micro filter (6) installed.
The filter cartridge to be replaced whenever required (automatic shut-
down initiated in case of low water supply by the low water cut-out).
Especially in case of excessive pressure in the water supply line and
clogged filter cartridge, the filter may crack, so allowing polluted water
to enter the pump, which would result in heavy damage of the pump
system, the proportional control valve (3) and the spray pistol.
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.
