INSTRUCTIONS FOR USE

LM05EN002
G.4 START
Before starting the pump, make sure that:

The mains voltage is compatible with the motor voltage and the relevant electrical control
panel.
MOVING PARTS HAZARD

Make sure the guards protecting the moving parts are fitted.

Check that the oil level in the gearbox is compliant with the required level (see paragraph
I.7.2).

Check that the direction of rotation of the motor is the one indicated on the belt cover: carry
out a rotation test.

Make sure that the motor circuit breaker is calibrated in accordance with the motor rated
values.

Check that the reversing valve is oriented towards the desired supply flow.

Check that any optional electrical components installed are correctly connected to the panel
and test their efficiency.

If the assessment of the delivery pressure is uncertain, e.g. because of high fluid viscosity,
equip the delivery pipeline with a pressure measurement device.
G.5 OPERATION

Start the pump in optimal condition: valves open and minimum speed, if adjustable.

Perform some starts and stops, checking the proper operation of the controls and that the
system is liquid-tight.

If the pump can be operated against closed valves, test the related safety devices (pressure
switch or bypass).

Make sure that in correct working conditions the flow rate, pressure and motor power
consumption values are in compliance with the design values.
G.5.1
ACTIONS TO BE AVOIDED
WARNING :

Do not change the use of the pump without carrying out the internal cleaning of the pump:
mixing chemical products can be very dangerous.

When the work process is terminated do not leave the pump full of product, especially in
the case of corrosive fluids or fluids that may deposit residues, polymerize or with the risk of
frost, or which may strain the mechanics upon the next start.

In case of insufficient motor power, do not increase the safety device settings beyond the
plate limits. Check system data and contact Ragazzini Technical Service if necessary.

Do not operate the reverse flow valve with the pump running.
HAZARD : When cleaning the pump with water jets, do not direct the jet on the motor or electrical
equipment.
Failure to comply with this disposition can generate an electrocution hazard as well as damage
to the electrical equipment.
G.6 STOPPING
G.6.1
Stopping the pump
The flow is stopped by stopping the motor. The pump acts as a valve except for the condition provided in
F.7.4.
G.6.2
Draining the pump
The pump is drained through the drain plug and by pumping air.
In case of risk of frost, drain the pump at the end of each processing cycle.
