DO NOT ALLOW THE PUMP TO RUN DRY (note: the ADH horizontal centrifugal pump design doesn't
allow dry-running operation because it will damage irrevocably the inner parts of the pump)
An accidental failure can generate sparks up to considerable distances.
In case of vibrations or abnormal noises, stop the pump immediately.
Do not pump flammable liquids.
Do not touch the pump while it’s operating.
Before touching the motor or the bracket switch off the power supply.
3.2 Dry-running
Fill the pump with water or with the liquid to be pumped before starting the unit. This will protect
the bearings and the shaft of the pump against dry running. DO NOT ALLOW THE PUMP TO RUN DRY
because this can cause serious damage to the internal parts of the pump due to the lack of the
necessary lubrication.
3.3 Temperature
Increasing the temperature of the pumped liquid can damage the pump and/or the piping/fittings and there
can be a situation of serious danger for the personnel nearby. Avoid sudden changes of the temperature and
do not exceed the temperature specified in your order. See the value of temperatures of the construction
materials of the pumps in paragraph 3.1.
3.4 Before Starting
Make sure that the pump is installed in accordance with the instructions previously stated in section 2. When
the pumping station is new, it's necessary to fill the system with water to ensure that there is no leakage.
WHEN THE PUMP IS INSTALLED ABOVE HEAD IT HAS TO BE PRIMED, THIS MEANS THAT IT HAS TO
BE FILLED WITH THE LIQUID AND THE SUCTION PIPING HAS TO BE KEPT FULL WITH LIQUID BEFORE
STARTING THE PUMP.
ATTENTION: some liquids react with water. VERIFY IF THE LIQUID TO BE PUMPED REACTS WITH
WATER. IN THIS CASE THE SYSTEM HAS TO BE COMPLETELY EMPTIED AND DRAINED.
