5.4 Filling filter (only for the grease version) (Accessory)
This removable cartridge filter is recommended to ensure the filling of lubricant which is free from foreign bodies and
to avoid the formation of air bubbles.
5.5 Hydraulic inverter (Accessory)
PART N°
86240
86199
Pressure up to 300 bar.
Type of lubricant: oil minimum viscosity 15 cSt – grease maximum consistency NLGI2
5.6 Auxiliary pump element
The pumps are supplied with one pump element only, but a second one can be mounted; this would permit the
feeding of two lines independently or the combining of the outlets of the two pump elements to obtain a doubling of
the flow rate.
To obtain the part number of the auxiliary pump element consult the table by utilising the last number off the 999
base pump, or its flow rate specification (at 1500 rpm) and its maximum working pressure.
5.7 Maximum level electrical contact
The metal tanks, except those of 3 and 5 litres, can be fitted with electrical maximum level indicators for
automatic replenishing of the tank.

6. UNPACKING AND INSTALLING THE PUMP
6.1 Unpacking
Once a suitable location has been found to install the unit remove the pump from the packaging. Check the pump has
not been damaged during transportation or storage. No particular disposal procedures are necessary, however
packing should be disposed of in accordance with regulations that may be in force in your area or state.
6.2 Installing the pump
Damage to the power supply cable and housing could result in contact with high voltage (220/380 VAC) live parts and
hence be a danger to life:
carefully check the integrity of the power supply cable and the unit before use;
In the event of there being damage to the power supply cable or the unit, DO NOT put the system into service!;
Replace the damaged power supply cable with a new one;
The unit can be opened and repaired ONLY by qualified personnel;
In order to prevent dangers of electric shock due to direct or indirect contact with live parts it is necessary that the
electrical power supply line is adequately protected by a suitable differential magneto-thermal circuit breaker with
an intervention threshold of 0.03 Ampere and a max. operating time of 1 millisecond.
The breaking capacity of the circuit breaker must be = 10 kV and the nominal current In = 4 A.
The connection of the pressure switch mounted directly on the tank must be 24 VAC/DC.
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;
