STORAGE OF THE PUMP UNITS
• Store the pump units in a dry place with a temperature between 5 and 30°C.
• Control the protection packaging and replace it if necessary..
• If the pump units have to be stored for a long time, it is better to fill the tank with oil, at least until to
cover the electric motor.
2.3 INVERTER
The inverter is delivered in a special packing or in a cardboard box.
STORAGE OF THE INVERTER
• Store the inverter in a dry place at a temperature between 5° and 30°C.
• Check the protective packaging and eventually replace it.
2.4 FLEXIBLE HOSES AND RIGID PIPES
PIPES TRANSPORT
• Avoid harsh bending of the flexible hoses.
• Prevent the flexible hoses from contact with caustic essences, solvents or other chemical
substances.
• Transport the flexible hoses in their original packaging.
• Avoid any kind of bending of the rigid pipes.
• Transport the rigid pipes with their caps on the ends.
STORAGE OF THE PIPES
• Store the pipes in a dry place, with a temperature between 5 and 30°C.
• Prevent the flexible hoses from the direct sunlight or the near presence of a heat source.
• Do not keep the flexible hoses stored for more than 2 years from the test date engraved on the fitting.
3 ASSEMBLING OF THE HYDRAULIC COMPONENTS
3.1 PUMP UNIT
The serial number of the pump unit is reported on the plate on the tank cover.
- All the pump units and the shut-off valves are tested and adjusted before the delivery.
For this reason they can work immediately, without any further adjusting.
When the installation has been finished, the oil filled and the air purged, it will be possible to readjust the low
speed and the deceleration to optimize the installation working (see instructions in paragraph 8.4)
The pump unit room has to be located as close as possible to the lift shaft, has to be big enough,
with an almost constant temperature, possibly heated in winter and ventilated in summer. If
distances are bigger than 8-10 meters, please consider the pressure loss along the main pipe.
Avoid noise transmission by using anti-vibration pads under the tank and a flexible hose for the
connection of the pump unit to the cylinder.
- The tank is equipped with handholds to be displaced manually and to be lifted with an hoist (see
Figure 1).
3.2 PIPE AND HYDRAULIC CONNECTIONS
Use cold drawn steel tubes, normalized and bonderized, special for hydraulic circuits, flexible hoses which
are tested and certified for high pressure or mixed connections to connect the pump unit to the cylinder.
- The shut-off valve can be turned to be better aligned with the pipe direction.
The shut-off valve can be turned to be better aligned with the pipe direction.
The main oil pipe as to be as short as possible and avoid narrow bending. The use of elbow fitting
