Warnings
NOTICE
Material damage due to the non-observance of optical or acoustic
warning signals!
Monitor all optical and acoustic warning signals, measured value
indicators and pilot lamps.
Follow all training and the operating manual.
Failure of the engine due to discharged battery!
The battery of the engine slowly discharges despite the ignition being
switched off.
Check battery charge status regularly (every three months).
Recharge or replace battery with low charge level.
Material damage due to cavitation!
With increasing suction lift the pump performance is reduced. Too high
suction lifts, very large flow rates and high pump speeds can lead to
cavitation in the pump. Cavitation causes extreme local pressure peaks,
which can damage the pump. Cavitation of the pump can be recognized by
a sharp drop in performance and noises in the pump, which sound as if
pebbles are being pumped. Cavitation of the pump must be avoided at all
costs, otherwise internal parts of the pump (e.g. impeller) are damaged. If
the suction hose is pulled together during external drafting operation, the
water column may break off.
Only operate pump in external drafting operation with suction strainer
and suction filter.
If there is danger of cavitation reduce pump speed, flow rate or suction
lift.
Do not operate the pump at high speed and free discharge.
Monitor all display instruments of the pump unit.
Observe the lowering of the water at drafting points.
Use dimensionally stable suction hose for external drafting operation.
Material damage due to use of extinguishing agent!
A mixture of dry powder and foam compound concentrate is highly
corrosive and difficult to remove.
Never mix dry powder and foam compound concentrate.
Danger due to water over flow!
Some materials expand and/or increase their weight when saturated with
water. Certain materials must not come into contact with water due to the
danger of chemical reactions.
In case of danger, immediately stop operation with water.
