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.
Allow a sufficient amount of space for installation, leaving a minimum perimetric space of 100 mm (3,93 in.).
For wall-mounting, suitable space must be provided (see the installation diagram) to prevent abnormal positions or the
possibility of impacts; install the pump at shoulder height. Then, the pump must be connected hydraulically to the machine and
the tank must be filled (making sure not to exceed the maximum visual level).
Empty the tank during the disassembly phase and disconnect the hydraulic part.
7. INSTRUCTIONS FOR USE
7.1 PRELIMINARY CHECKS
-
Check the integrity of the pump. (The unit may only be opened and repaired by specialised personnel).
-
Check that the hydraulic connection was carried out correctly.
-
Fill the tank with lubricant free of impurities.
7.2 USING THE PUMP
Pump operation is very simple: simply pull the lever with a decisive and complete movement and release it. We recommend
carrying out a few cycles to bleed the air from the system.
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 protective 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 technical office.
Do not ignore the hazards to health and comply with the health regulations.
8. PROBLEMS AND SOLUTIONS
ANOMALY
CAUSE
SOLUTION
The pump does not deliver
or does not deliver the
required quantity
The pump intakes air because the tank is
empty
Refill the tank and bleed the air from the system
The fittings are loose
Carefully tighten al the fittings making sure there
are no leaks
The pump does not deliver
at the required pressure
Pump deteriorated
Replace the pump
By-pass valve decalibrated
Turn the pressure adjustment screw
9. MAINTENANCE PROCEDURES
The pump was designed and built in order to minimise maintenance requirements.
To simplify maintenance, it is recommended to install it in an easy to reach position.
Periodically check the pipe joints and always keep the pump clean to detect any leaks or defects.
The machine does not require any special equipment for any control and/or maintenance activity. It is recommended to use
tools and personal protective devices suitable for use (gloves) and that are in good condition according to current regulations to
prevent damage to people or machine parts.
In the case of doubts and/or problems that cannot be solved, do not try to discover the reason by disassembling machine parts,
but contact the DROPSA S.p.A technical office.
ATTENTION: make sure that the hydraulic power supply is disconnected before carrying out any maintenance work.
