• Check the electrical cabinet for any broken
components.
• Check that all motor starter connections are
tight and that there are no loose objects such
as terminal lugs, screws, nuts, etc., in the
cabinet.
3A.2 Initial Start-up
3A.2.1 Lubrication
The pumps are oil lubricated. The lubricating oil
can be put into the pump at the oil
fi
ller port of
the oil separator housing, observing the “MAX”
and “MIN” position at the oil level sight glass.
(For recommended oil type, refer to Section 6.1.)
After
fi
lling make sure the oil
fi
ller port is closed.
3A.2.2 Pump Rotation
Prior to actual operation, the pumps must be
checked for correct rotation. See section 2.5
Electrical Requirements regarding pump rota-
tion.
Inside the control panel, make sure that all unit
printed circuit boards are set to the manual
override “OFF ” position. This is indicated by the
middle position “X” on the three-position sliding
switch as shown in Figure 3A.1.
CAUTION:
Complete the prestart-up procedure before
continuing with the initial start-up procedure.
WARNING:
To prevent electrical shock, ensure that
ALL electrical power to the system is OFF,
including the disconnect switches. The
facility’s supply circuit breaker should also be
locked out.

NOTE:
All VerusLab lubricated vacuum pumps
are shipped with the required amount of
oil for start-up. The systems are shipped
with separate oil containers, which must
be added before start-up.
NOTE:
The shelf life of oil
fi
lters is six months.
Systems stored longer than this should
have all
fi
lters replaced prior to
fi
rst start-
up. See Section 7.0 for replacement
