Warning notes
NOTICE
Damage due to cavitation!
The pump capacity is reduced with increasing suction height. When
operating with great suction heights, high pump speeds and very high
discharge rates, the pump may cavitate. Cavitation causes extreme
pressure and temperature peaks which can destroy the pump. Cavitation
may sound like marbles are being pumped through the system. Cavitation
must be avoided by all means, because the pump internal parts (e. g.
impeller) might be damaged by this excessive load. A constricted suction
hose while external drafting may result in loss of the water flow.
In external drafting operations from open water never run the pump
without a strainer.
If cavitation occurs, reduce pump speed, suction height or water
discharge.
Never run the pump at high speed with a free outlet.
Monitor all display instruments of the pump.
Watch declining water level of the water source.
Use non-collapsible hose for drafting operation.
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 portable fire pump due to depleted battery!
The battery of the portable fire pump discharges in continuous occupation,
with the engine off and the ignition switched off or on.
Check battery charge status periodically (every three months).
Recharge or replace battery with low charge level.
The leakage current on the electrical components of the portable fire
pump is approx. 0.5 mA.
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.
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.
