Improper use
WARNING:
Improper use of the pump may create
dangerous conditions and cause
personal injury and damage to property.
An improper use of the product leads to the loss
of the warranty.
Examples of improper use:

Liquids not compatible with the pump
construction materials

Hazardous liquids, such as toxic, explosive,
flammable, or corrosive liquids

Potable liquids other than water, for
example, wine or milk
Examples of improper installation:

Hazardous locations, such as explosive, or
corrosive atmospheres.

Location where the air temperature is very
high or there is poor ventilation.

Outdoor installations where there is no
protection against rain or freezing
temperatures.
DANGER:
Do not use this pump to handle
flammable or explosive liquids, or both.
NOTICE:

Do not use this pump to handle liquids
containing abrasive, solid, or fibrous
substances.

Do not use the pump for flow rates beyond
the specified flow rates on the data plate.
Special applications
Contact the local sales and service representative
in the following cases:

If the density or viscosity value of the
pumped liquid exceeds the value of water,
such as water with glycol; as it may require a
more powerful motor.

If the pumped liquid is chemically treated, for
example softened, deionized, demineralized
etc..

Any situation that is different from the ones
that is described and relate to the nature of
the liquid.
