6. UNPACKING AND INSTALLATION
6.1 UNPACKING
Once a suitable installation position has been identified, unpack the pump and prepare for installation. It is important to inspect
the pump 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 PUMP INSTALLATION
Allow sufficient space for install with 150mm clear space around the perimeter of the pump.
Mount the pump LocopumpSerie2 at “eye level” to avoid any risk of postural problems.
Do not install the pump in dangerous environments such as explosive/flammable areas or in areas subject to high vibration.
Only use the fixing holes on the support bracket which are intended for n°2 holes for screws Ø10 mm (0,4 in.)(use a flat washer
with the screw ). For more details of the fixing holes please verify the dimensions shown on the drawing in chapter 12.
6.3 ELECTRICAL CONNECTIONS
Ensure the electrical connection of the low level is connected before using the pump. See below drawing for connection details.
A label of this drawing is also on the pump’s reservoir.
Supply voltage 24 V max.
6.4 PUMP OUTLET CONNECTION
The hydraulic connection of the pump is on the front face of the pump. It is a standard 1/4” BSP ( see drawing in chapter 12 ).
6.5 AIR CONNECTION ON PUMP
Use an 1/8” BSP connection fitting. It also possible to use DropsA’s nut an cone fittings as the seating is already available.
Remember to use a 3/2 valve that allows the air to vent to atmosphere and the internal spring within the pump to reset.
6.6 HOW TO ADJUST THE PUMP OUTPUT OR PRESSURE
This can be done by: Regulating pressure: the output pressure has a 50:1 ratio with the inlet pressure. Therefore this can be
regulated depending on the requirements of the system. (See chapter 4 for min and max pressures).
Regulating pump: as standard the pump has a fixed output. For special requirements you can convert the pump by installing the
kit 3133390 –ordered separately to the pump –the kit is shown below.
To use this kit , mount the o-ring ( A ) then tighten the fitting ( B ) with a 27mm spanner. Loosen the counter nut (C) with a 13
mm spanner to unblock the screw (D), use the appropriate screw driver to screw IN for less output or screw OUT for more
output. After adjustments have been made you must tighten the counter nut (C) to block any further movements.
N.B.: After all connections have been made please ensure that they are safe and properly secured down.
WARNING: The unit is only to be opened and repaired by specialist personnel.

9. MAINTENANCE PROCEDURES
Ensure the pump is positing so that it can be verified easily.
Ensure you have necessary personal protective equipment to avoid any contact with the grease.
The pump undergoes severe factory testing therefore no maintenance is forecasted with the pump.
DropsA recommends the use of lubricants that are free of any impurities as well as a regular cleaning of the pump’s
components.
The pump is dismantled as follows:
1. Before removing the reservoir is must be completely emptied of lubricant.
2. Disconnect the air inlet connection.
3. Disconnect all tubing on the pump.
4. Loosen the screws on the lid, remove the reservoir taking ABSOLUTE care of the spring inside the reservoir ( it may still be
under tension –if so remove more lubricant.)
5. Remove the pump and any filters if fitted.
6. Unscrew the plug on the pneumatic pump body, be careful of the load on the internal spring. At this point you can remove
the internal components of the pump body.
At this point all components are loose and allow the cleaning and verifying of each component possible.
All components must be clean with cleaning fluid and lubricated before re-assembly.
Periodically it is necessary to check:
CHECK
TOTAL NUMBER OF PUMP CYCLES
The lubrication status
100
Lubricant level
200
Clean refilling filter
400
Clean bottom of reservoir if deposits have formed.
600
The machine does not require any special equipment for any checking and/or maintenance activity, however the
recommendation is to use suitable equipment which is in a good condition (according to current regulation) in order to avoid
causing damage to persons or machine parts.
Make sure that the electric and hydraulic supply has been disconnected before carrying out any maintenance intervention.
10. DISPOSAL
In the course of machine maintenance, or if the machine is scrapped, do not dispose of polluting parts into the environment.

13. HANDLING AND TRANSPORT
Prior to shipping, the equipment is carefully packed in cardboard package. During transportation and storage, always maintain
the pump the right way up as indicated on the box. On receipt check that package has not been damaged. Then, store the
machine in a dry location.
14. PRECAUTIONS FOR USE
It is necessary to carefully read the warnings and risks associated with using a lubricant pump. The operator must understand
how it works and must clearly understand the dangers by studying the user manual.
Power supply
Any type of intervention must not be carried out before unplugging the machine from power supply. Make sure that no one can
start it up again during the intervention.
All the installed electric and electronic equipment, reservoirs and basic components must be grounded.
Flammability
The lubricant generally used in lubrication systems is not flammable. However, it is advised to avoid contact with extremely hot
substances or naked flames.
Pressure
Prior to any intervention, check the absence of residual pressure in any branch of the lubricant circuit as it may cause oil sprays
when disassembling components or fittings.
Noise
Pump produces noise, not more than 70 dB(A).
15. OPERATIONAL HAZARDS
The check on compliance with the essential safety requirements and with the stipulations indicated in the machine directives
are to be carried out by means of compiling the checklists already made available and contained in the technical file.
Two types of lists were used:
List of dangers (section from UNI EN ISO 14121-1 relating to UNI EN ISO 12100)
Application of the essential safety requirements (Machine Dir.)
See below a list of dangers which have not been completely eliminated, but are considered acceptable:
During assembly/maintenance it is possible that there may be an oil splash (consequently this operation must be carried out
using appropriate individual protective devices);
contact with oil -> see instructions for using appropriate individual protective devices DPI;
Loaded springs, in the pump cylinder and in the reservoir.
Use of an inappropriate lubricant -> fluid characteristics indicated both on the pump and in the manual (if in doubt consult
our Technical Office);
protection against direct and indirect contact must be provided by the user;
The pump’s working logic requires it to operate at all times, so it is necessary to pay attention to the electric connection. If
there is no current the customer’s machine can only be restarted following a reset while the lubrication pump can restart
automatically.
Do not use alcohol or spirits to clean any components.
