needs only to be disconnected from the electric power.

tion rules.
WARNING!
Death may result from contact with high voltages. Always take
extreme care and observe the accident prevention regulations
in force.

parts and high voltages.
WARNING!
If you have to perform maintenance on the pump after a con-
siderable time in operation, leave it to cool as temperature of
the outer surface may be in excess of 60 °C.
WARNING!
Always disconnect the power supply to the pump before start-
ing maintenance work. Place a special warning signs over the
power supply breaker switch: MACHINE UNDERGOING
MAINTENANCE - DO NOT POWER ON. When finished, re-
move the safety warning.

The following symbol is applied in accordance with the EC
WEEE (Waste Electrical and Electronic Equipment) Directive.
This symbol (

disposed of together with ordinary domestic or industrial waste
but must be sent to a differentiated waste collection system.
The end user is therefore invited to contact the supplier of the

collection and disposal process after checking the contractual
terms and conditions of sale.
