5 - INSTALLATION AND START-UP

This chapter describes the methods of installation of the pump. The method here recommended will give excellent results. The purchaser
of the pump, i.e. the manufacturer of the machine on which the pump will be installed, may opt for different types of installation, using
brackets or any other types of accessory considered to be necessary. HOWEVER, THE ORIGINAL SHAPE AND ATTACHMENT OF
THE PUMP MUST NOT BE MODIFIED, THE PROTECTIONS APPLIED TO THE PUMP MUST NOT BE TAMPERED WITH AND NO
ACTION MUST BE TAKEN THAT COULD MAKE THE PUMP POTENTIALLY DANGEROUS. If these instructions are disregarded, the
person who is responsible for the modifi cations automatically assumes full liability for any accidents that may occur during use of the pump.
The pump can be installed in a horizontal or vertical position.
Figure 2 on page 3 and 4 shows the drilling template to use when designing the pump baseplate (fi g.2a -> 2.4 Lt. pump / fi g.2b -> 5 - 7
- 10 - 20 Lt. pump).
IMPORTANT: the fi xing hole depth for pump with 2.4 litre reservoir is 20 mm. This length must not be exceeded.
The fi xing screws must be self-tapping type for plastic - Ø 5 - UNI 9707.
WARNING
IF THE PUMP'S CONTROLS ARE EXPOSED TO FALLING OBJECTS OR SOMETHING OTHER THAT COULD
ACCIDENTALLY HIT THEM AND CAUSE AN UNEXPECTED START-UP, IT IS NECESSARY TO INSTALL AN
APPROPRIATE PROTECTION IN ORDER TO AVOID THIS HAZARD AND RESTORE THE SYSTEM SECURITY.
THE PROTECTION MUST STAND ON TO THE CONTROL MECHANISM.

5.1 - Filling the reservoir (if the pump is supplied without oil)

The table "TECHNICAL SPECIFICATIONS" (page 19) shows the oil quantities required to fi ll the pump reservoir. The table also shows
the actual usable oil capacities. Use the oil types specifi ed in the table. The use of oil with different characteristics can result in serious
damage to the pump and render it unsuitable for use.
THE MANUFACTURER SHALL NOT BE HELD RESPONSIBLE FOR INJURY TO PEOPLE OR DAMAGE TO
PROPERTY CAUSED BY THE USE OF UNSUITABLE OR EXHAUST OIL. DAMAGE TO THE PUMP RESULTING
FROM THE ABOVE MENTIONED CAUSES IS NOT COVERED BY WARRANTY.
● Use a slotted tip screwdriver to remove the fi ller plug (fi g.12, page 17)
● Pour the correct quantity of oil into the reservoir (rrefer to the table "TECHNICAL SPECIFICATIONS", page 19)
● Clean the edges of the fi ller opening with a clean cloth and refi t the plug, pressing it down fully.

5.2 - Pump hydraulic connections

THE INSTALLATION OF A DEVICE THAT INTERCEPTS THE PNEUMATIC AIR SUPPLY IS RECOMMENDED
TO RAPIDLY DISCONNECT THE PUMP FROM PNEUMATIC CIRCUIT IN CASE OF NEED OR MAINTENANCE.
BEFORE CARRYING OUT ANY CONNECTIONS, VERIFY THE CONDITION OF FITTINGS AND SEALS AND
ENSURE THREADS AND PIPES ARE CLEAN AND INTACT.

5.2.1 - Pump hydraulic connections (UPC and UPM models)

● Connect the hydraulic pressure hoses to the outlet port (A, fi g.3, page 4) and reservoir port (B, fi g.3, page 4) on the pump. The hoses
must be fi tted with a G1/4" coupling with seal washer.
● Unscrew the breather screw (fi g.4, page 4) by three or four turns using the correct type of screwdriver.

5.2.2 - Pump hydraulic connections (UPL model)

● Connect the end of a hydraulic pressure hose to the outlet port (A, fi g.5, page 4). Connect a directional control valve in the line to
supply the system and allow the oil return to the reservoir.
● Connect the valve to the reservoir port (B, fi g.5, page 4) with a hose. The hoses connected to the pump must be fi tted with SAE#4
couplings.
● Unscrew the breather screw (fi g.4, page 4) by three or four turns using the correct type of screwdriver.

5.3 - Setting up the pump

5.3.1 - Setting up the pump - horizontal position

● If the pump is to be used in the horizontal position, unscrew the breather screw (fi g.4, page 4) by three or four turns using the correct
type of screwdriver.

5.3.2 - Setting up the pump - vertical position

● If the pump is to be used in the vertical position, use a slotted tip screwdriver to extract the breather plug to the fi rst click (pos. D in
fi g.6, page 4).
