6. UNPACKING AND INSTALLATION
6.1 UNPACKING
Once the suitable location for installation has been identified, open the package and remove the pump. Check that it was not
damaged during transport or storage. The packaging material does not require special disposal precautions as it is not in any
way dangerous or polluting. Refer to the local regulations for disposal.
6.2 INSTALLATION
Pump assembly operations are not required.. The pump is fixed on a metal pallet that permits safe handling with a transpallet or
fork lift truck. The pallet was designed to be installed in the plant. It has four
14
mm holes suitable for fixing to the floor.
Suitable space must be provided (as shown in the installation diagram) to prevent abnormal positions or the possibility of
impacts. Then, as described above, the pump must be connected hydraulically to the machine and then the connection to the
control panel must be made.
7. INSTRUCTIONS FOR USE
7.1 STARTING THE PUMP
Before using the MINI SUMO pump, a few preliminary checks must be performed:
•
Check the integrity of the power supply cable and the unit prior to use.
•
If there is damage to the power supply cable or the unit, do not start operations!
•
Replace the damaged power supply cable with a new one.
•
The unit may only be opened and repaired by specialised personnel.
•
In order to prevent the danger of electrocution due to direct or indirect contact with live parts, the electric power supply line
must be suitably protected by a specific differential magnetothermic switch, according to regulations and with rated
breaking capacity at list equal to prospective fault current at installation point.
•
It is prohibited to use the pump if submersed in fluids or in a particularly aggressive or explosive/inflammable environment if
not previously prepared for that purpose by the supplier.
•
Use safety gloves or glasses as specified in the safety sheet for the lubricating oil
•
DO NOT use aggressive lubricants with NBR gaskets. In the case of doubt, contact the Dropsa SpA technical office to receive a
detailed card about the recommended oils.
•
Do not ignore the hazards to health and comply with the health regulations.
•
Check the integrity of the pump.
•
Check that the pump is at the operating temperature and that there are no air bubbles in the pipes.
•
Check that the electric connection was carried out correctly.
•
Once the pump has started, check that the direction of rotation of the electric motor is as indicated by the arrow on the
motor's protective casing; if it rotates backward; reconnect it as shown in the wiring diagram provided with the motor.
7.2 INSTRUCTIONS FOR USE
1)
Press the start button on the machine to which the pump is connected or start it;
2)
Check the that the pump starts;
3)
To change the pressure value, turn the adjustment screw (see Chap. 5). Turn it clockwise to increase the pressure or counter
clockwise to decrease it;
4)
Check that the machine lubrication is suitable (if there are doubts about correct operation, the Dropsa SpA technical office
can be contacted to request the inspection procedure).
ATTENTION
:
All components must be ground connected. This applies both to electric components as well as to control
devices. For this purpose, make sure that the ground wire is directly connected. For safety reasons, the ground conductor
must be approx. 100 mm longer than the phase conductors. If the cable is accidentally disconnected, the ground terminal
must be the last to be disconnected.
