6. UNPACKING AND INSTALLATION
6.1 UNPACKING
Once a suitable installation position has been identified, unpack the product and prepare for installation. It is important to
inspect the product 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.
6.2 INSTALLATION
No pump assembly operations are envisaged. The pump is fixed on a metal pallet, which allows safe handling using a
transpallet or forklift truck. This pallet has been designed so that it can be installed in the installation, being
equipped with 4 (four) holes of Ø 14 mm suitable for fixing to the floor. Provide adequate space (as shown on the
installation diagram) to avoid abnormal posture or possible impact. Then, as described previously, the pump must be
connected hydraulically to the machine and then connected to the control panel.
7. OPERATING INSTRUCTIONS
7.1 START-UP OF THE PUMP
Before using the product, a few preliminary checks must be performed:
•
Check the integrity of the supply cable and the unit prior to use;
•
If the supply cable or the unit is damaged, do not start up the system!
•
Replace the damaged supply cable with a new one;
•
The unit can be opened and repaired only by specialist personnel;
•
In order to prevent the danger of electrocution due to direct or indirect contact with live parts the electric supply line must
be adequately protected by an appropriate magnetothermal differential switch with threshold of intervention of 0.03
ampere and max intervention time of 1 second;
•
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 lubricants which are aggressive towards NBR gaskets, and if in doubt consult the Dropsa SpA technical office
which will supply a detailed list of the recommended oils;
•
Do not ignore dangers to health and comply with health and safety regulations;
•
Check the integrity of the pump.
•
Check that the pump is at working temperature and that there are no air pockets in the pipes.
•
Check that the electric connection has been 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
Press the start button on the machine to which the SUMO II pump is connected.
1)
Check pump start-up.
2)
To change the pressure value, turn the by-pass adjustment screw (see Chap. 5). Turn it clockwise to increase the pressure
or counter clockwise to decrease it;
3)
Check that the machine is adequately lubricated (if there are still some doubts about its correct functioning you can contact
the Dropsa S.p.A Technical Office and request a test procedure).
The interruption power of the switch must be
≤
10 kA and rated current In
=
6 A.
Warning! All the electric components must be earthed. This applies to both the electric components, and to the control
devices. To this end make sure that the earth wire is connected correctly. For safety reasons the earth conductor must be
approximately 100 mm longer than the phase conductors. If the cable is accidentally removed, the earth terminal must be the
last one to be removed.
