CORRECT USE
3.1
Putting into service
The unit may be used, opened and repaired only by specialised personnel;
The pump MUST NOT be submersed in fluids or utilised in environments which are particularly aggressive or
explosive/inflammable if not prepared for this purpose beforehand by the supplier;
For correct fixing verify the distance between centres shown in the diagram in Section 2
Use gloves and safety glasses as required in the lubrication oil safety chart;
DO NOT use aggressive lubricants with NBR gaskets and seals; if in doubt consult the Engineering Department
of Dropsa SpA, who will provide a chart with the details of recommended oils;
DO NOT ignore dangers to health and observe all hygiene standards;
WARNING! All electrical components must be grounded. This refers to both electrical components and control
devices. In this regard ensure that the ground cable is correctly connected. For reasons of safety the ground
cable must be approx. 100 mm longer than the phase cables. In the event of accidental detachment of the
cable, the ground terminal must be the last to be removed.
action to be taken prior to start up
Verify the integrity of the pump;
Fill the tank with suitable lubricant (min/max indication on the tank);
Verify that the pump is at operating temperature and the tubing free from air bubbles;
Check that the electrical connections have been effected correctly (CEI 64/8, IEC 364);
Verify the correct connections of any level and pressure switches to the control panel;
The minimum level indicator is supplied, unless otherwise specified by the customer, with the contact closed
for minimum level. Should the user require to use a normally open contact it will be necessary to open the
tank and to invert the operating direction of the float.
3.2
Use
1.
verify the settings on the control panel, where fitted;
2.
press the start button of the machine to which the pump is connected;
3.
verify the starting of the pump;
4.
verify the adequate lubrication of the machine (if doubt exists as to the correct functioning consult the
Engineering Department of Dropsa SpA to request test procedures).
3.3
Transport and storage
Transport and storage is effected in a cardboard package
No particular precautions are required except as noted on the package itself.
Handling can be effected by one person.
!
Lift the unit with taking account of the right way up indicated on the cardboard carton
!
The machine components can withstand temperatures, during storage, from -20 to +50°C; however, in
order to avoid damage, starting of the machine should occur at a minimum temperature of -5°C.
3.4
Assembly/Disassembly
No pump assembly operations are envisaged.
For wall mounting ensure adequate space is available (as shown in the installation diagram) to avoid abnormal
postures and possible impacts; four fixing holes are provided with different characteristics depending on the
version (see section 2.2)
Subsequently it will be necessary, as previously described, to connect the pump to the machine hydraulically and
then to connect the control panel.
During the disassembly phase ensure the tank is empty.
