the accessories supplied.

Installation
Before using the vacuum pump, it is convenient for you to familiarize with its compo-
nents and basic essentials, as well as with its control functions.
PLEASE READ THOROUGHLY THE INSTRUCTIONS BEFORE CONNECTING
AND OPERATING WITH THIS EQUIPMENT WITH THE AIM OF ACHIEVING
THE HIGHEST FEATURES AND THE MAXIMUM DURABILITY OF THE INS-
TRUMENT
Put the pump on top of a horizontal, plane and stable surface so as vibrations produced
during operation do not disturb nearby equipments. The back side of the pump must be
perfectly ventilated and free of obstructions.
Do not put the pump near any warm supply (burners, blowlamps…), nor expose it
directly to the sun, etc. During operation, flammable liquids must be out of the working
area.
Open the oil inlet cap
(1.5)
and fill the pump until the oil level reaches the middle of the
sight glass
(1.4)
.
Make sure that the switch
(1.2)
is off and insert the Schuko wire that feeds the AC elec-
tric current in the base of current 220 V, 50 Hz ± 10% provided with earth wire.
Neither the manufacturer nor the distributor will assume any responsibility for the
damages produced to the equipment during its installation or damages to persons suf-
fered by the improper use of the electric connection. The tension should be 220 V, 50
Hz ± 10%.
Setting up
High vacuum pumps are designed to offer highly satisfactory results for a long time
and don’t need a special assembly.
The aeration hose must be flexible to avoid a possible transmission of vibrations, water-
tight and with the same or higher calibre than the pump connection (depending on the
distance to cover) to obtain an optimum output.
Note: model 59001102 presents double vacuum connection. During operation, the con-
nection that is not in use must be perfectly protected by its cap (1.8) to avoid leaks.
