INSTALLATION, START UP AND SWITCHING OFF

8.1

POSITIONING

Smaller and lighter Pumps can be handled by hand in compliance with current standards. Heavier
Pumps must be handled using the dedicated hook and suitable lifting device. If there is no eyelet and
you need to use a lifting device, use appropriate strap/s, being careful not to damage the product.
The weight of the Pumps is written in the table on page 25.
If the Pump is used in a particularly dirty workplaces or is exposed to atmospheric agents, you are
recommended to protect it, respecting the ventilation conditions.
8.2

ASSEMBLY

Fit the Pump on a rigid surface keeping the power take-off and support feet horizontal to ensure
correct drainage in the case of leakage of water or oil. The Pump must be secured firmly on a base,
which must be perfectly aligned with the transmission components. In the case of belt transmission,
make sure the pulleys are aligned and check the tension of the belts.
Use appropriately sized hoses, both on the inlet and outlet of the Pump, according to the technical
specifications written on the Label
8.3

START UP

Before starting, check the following:
Replace the RED cap on the Pump Crankcase with the venting cap in the kit of
accessories supplied.
- Check the oil level through the dedicated oil reservoir or inspection cap; top-up if necessary.
- Check the pressure value on the accumulator, if installed; inflate or deflate if necessary.
- The pressure regulator valve must be set at "0" pressure to favour intake.
Start and run the Pump for approximately 10 seconds until all the liquid has discharged from the
delivery line. Once the intake cycle is complete, you can set the Pump at the required pressure, by
adjusting the pressure regulator valve, without ever exceeding the maximum pressure written on the
Pump's Label.
8.4

SWITCHING OFF AND STORAGE

After use or if the Pump is to be put away in storage, wash it internally. You can do this by running
the Pump for several minutes with clean water, then disconnect the supply line and leave the Pump
to run for approximately 15 seconds so that all the water in the head is discharged.
A few minutes devoted to the internal washing of the pump brings considerable benefits in terms of
the pump's lifetime.
Do not wash the Pump externally: water could get into the Pump crankcase, for example
through the oil vent cap.
After switching off, the Pump could remain very hot for some time.
Do not throw the liquid used to wash the Pump outdoors but observe current standards.
8.5

PRECAUTIONS AGAINST FREEZING

If shutdown during winter or in the case of places and seasons subject to frost, once the Pump has
finished working, run it for the time required to Pump an emulsion of 50% of clean water and 50% of
antifreeze fluid through it in order to prevent freezing and damage to the Pump.
