FIRST FILLING/REPLACEMENT OF PRELOADED CARTRIDGE
(CARTRIDGE VERSION)
The pump is supplied without a cartridge and completely empty. When the pump is ordered, the cartridges that will be used
must also be ordered based on the type of grease foreseen. Provide an extra cartridge which will be used for the first filling.
For the first filling (with pump completely empty), you must proceed as follows:
Remove the cartridge guard with bayonet fastening.
Remove the cartridge plug.
Screw the cartridge onto the pump all the way, tightening it moderately.
Unscrew and remove the plug or pumping unit if present in “C” position. (See 14 chap. ORDERING INFORMATION.
Keep the pump in horizontal position.
Press the cartridge manually and gradually, sending the grease into the pump and evacuating the air.
as soon as you notice the grease coming out of the hole where the previously removed plug was, stop pushing on the
cartridge.
Screw on and tighten the plug previously removed.
For replacement, you must proceed as follows:
Remove the cartridge guard with bayonet fastening.
Unscrew and remove the empty cartridge.
Recover the magnet from the empty cartridge (used to signal the minimum level).
Insert the magnet on the new cartridge.
Remove the cartridge plug and remove the protection film (if present).
Press the cartridge slightly so that a small quantity of grease comes out, ensuring that you evacuate all the air in the
mouth.
Taking care not to allow the air to come back in, screw the cartridge onto the pump all the way, tightening it
moderately.
Insert the magnet in the new cartridge.
Refit the guard with bayonet fastening.

SETTING OF ADJUSTABLE PUMPING UNIT
To set the progressive pumping unit with adjustable flow, proceed as follows:
Ensure there is no residual pressure in the pressure line.
Remove the adjustment access cap using a 4mm Allen wrench (see 5.3.“Progressive” PUMPING UNIT).
Rotate the jacket of the pumping unit using a 4 mm Allen wrench inserted in the internal grub screw.
Each complete rotation of the Allen wrench is approximately 0.6cc/min. Setting range from 0.4 to 2.8 cc/min. for a total
of 4 rotations.
Check the presence and conformity of the copper gasket (replace if necessary).
Replace the cap using a 4 mm Allen wrench.

VENT VALVE KIT INSTALLATION (OPTIONAL)
The optional vent-valve (release valve) kit is designed for use with the fixed-flow pumping unit in position B. However, in case
of a new pipe for the installer, it can be used with different solutions (see 5.6.VENT-VALVE KIT).
For assembly and use, proceed as follows:
Remove the screw with a gasket on the lower part of the pump.
Screw the two self-tapping screws into the holes provided, ensuring the presence of the central gasket.
Tighten the union on the pump in position B.
The free connector and the power cord must be of an adequate size and type, in compliance with applicable provisions.
This can be ordered separately (see 11. ORDER INFORMATION).
