Set-up of pump before first operation
Pump is supplied without oil charge; before initial
operation, it is mandatory to fill the pump with the
recommended oil charge (see "Filling of oil").
Filling of oil
Pump must be turned off for filling the oil and level
control.
Pump is supplied with a mineral oil bottle but without oil
charge inside the vacuum pump; before initial operation,
it is mandatory to fill the pump with the oil up to the
indicated oil level in the oil level sight glass. Only use

oil;
performance and may cause irreversible damage to the
pump. Warranty is void if other oil has been used. For fill-
up proceed as follows:
1. Unscrew charging plug (placed on upper part of pump)
2. Slowly add the oil until middle of sight glass has been
reached (indicated by MAX MIN line)
3. Screw-on the plug again
To avoid excessive filling, it is suggested to only add the oil
with a graduated recipient; in that way it is easy to check
the added volume. In case of excessive filling, it is
necessary to completely empty the pump and repeat the
oil filling procedure.

WARNING: Do not pollute the environment by spilling
oil; the lubricant oil is a special waste and must be
disposed off according to relevant local law / guidelines
in force.
Connection for evacuation
Shorter hose length or wider ID, as well as straight path,
reduce the evacuation time as the pump will reach the
desired vacuum more quickly. To prevent backflow of
lubricant from the pump into the evacuated system in
case of unexpected power failure, a solenoid non-return
valve is provided at the suction connection.
Power Supply
reduce
Always check the power supply; it has to comply with the
data on the rating label on the pump. The pumps' motor
is equipped with a thermal overload protection with
automatic reset and cuts off power supply at +130°C /
+266°F. General precautions
The pumps' motor must always be suitably grounded. The
pump temperature is not expected to rise to a very high
level during operation; however it is advisable to locate
the unit in such a way that no contact can be made, as it
may cause burns. When using the pump with other
equipment, it must be ensured that the pump is fixed
properly and safe to use for the operator. Vacuum pump
is air cooled by built-in fan; only use where the air can
freely circulate and keep it away from walls or obstacles
no less than 2 " (5 cm). Do not cover the pump during
operation.
