1.4 Open corner valves (Fig.1/4) and stop
valve (3) and set water pressure on
pressure gauge (5) to
1,2 - 1,5 bar
Duration of washing: 5 minutes
1.5 Close stop (Fig.1/3) and corner valves (4)
and remove hose clip (1).
1.6 If no further water runs out of the drain
pipe (Fig.2/2), close the drain valve (1).

about 30 minutes at the specified engine
load, then slowly increase the engine load.
CAUTION
Check drain valve (Fig. 2/4)
and pipe (2) during the washing
process permanently for free
passage. Clogging by deposits
involves the risk that water runs

arger, repeat the washing process.
