8. OPERATING HAZARDS

The micro pump has no particular contraindications except for the following points:

•

Contact with fluid for breaking / opening of adduction piping. -> The operator must be equipped appropriate

individual protective devices DPI.

•

Unsuitable postures. -> See paragraph 9.2.

• contact with oil -> see instructions for using appropriate individual protective devices DPI;

• Use of an inappropriate lubricant -> fluid characteristics indicated both on the pump and in the manual (if in doubt

consult our Technical Office);

Fluids

Lubricant with abrasive additives

Lubricant with silicon additives

Benzine – solvents – inflammable liquids

Corrosive products

Water

Food substances

UNPACKING AND INSTALLING

9.1 UNPACKING

Once a suitable installation position has been identified, unpack the pump and prepare for installation. It is important to

inspect the pump to ensure that there has been no damage during transportation. The packaging material used does not

require any special disposal procedures. You should refer to you regional requirements.

9.2 PUMP INSTALLATION

There are no installation operations of pump.

Allow sufficient space for install with 100mm clear space around the perimeter of the pump.

Mount the pump at "eye level" to avoid any risk of postural problems. There are two fixing holes on the plate, with

different distances depending on the 1 Lt and 1.7 Lt version.

Afterwards is necessary connect he pump to the machine with hydraulic connection, refill the reservoir and connect to

the control panel.

Empty the reservoir during the disassembly phase.

Disconnect electrical and hydraulic parts.

9.3 HYDRAULIC CONNECTIONS

Only connection is to be made from the pump to the lubrication point or the metering valves.

9.4 ELECTRICAL CONNECTIONS

Before carrying out any wiring, ensure that the correct power supply is available. Refer to the identification label on the

Pump. In order to avoid dangers of electric shock it is important to remove all power before installation or maintenance.

All electrical components and control devices must be grounded. Make sure that the ground wire is correctly connected.

For safety reasons, the earth conductor should be approximately 100 mm longer than the phase conductors. In case of

accidental cable detachment, the ground terminal must be the last to come off.

In order to prevent dangers of electric shocks due to direct or indirect contact with the energized parts, electrical power

supply line must be protected by a suitable magneto-thermal circuit breaker with an intervention threshold of 30mA and

1 millisecond minimum operating time.

Circuit breaker power must be = 10 kV and nominal power in In = 6 A.

N.B.: after all connections make sure that pipes and cables are appropriately fixed and protected from impacts.

UNACCEPTABLE FLUIDS

High consumption of contaminated parts

Jamming of the pump

Fire – explosion – damage to gaskets

Corrosion of the pump – injuries to persons

Pump oxidation

Contamination of these substances

Dangers
