• 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.
3B.2 Initial Start-up
3B.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.
3B.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.
Check all voltages supplied to the vacuum sys-
tem to ensure they are the required value and
phases needed by the control panel.
Apply power to the system and turn the dis-
connect switches to “ON”. Make sure the Hand-
Purge/O
ff
-Auto switches are in the “PURGE/OFF”
position as shown in Figure 3B.1
Using the Hand-Purge/O
ff
-Auto switch on the
door of the control panel, jog the motor of the
speci
fi
c pump that is to be checked by momen-
tarily turning the switch to “HAND” and then
pressing the emergency stop button. Turn the
Hand-Purge/O
ff
-Auto back to “PURGE/OFF ” and
then twist (1) and release (2) the emergency stop
button (see Figure 3B.2).
By observing the cooling fan of the motor, you
can determine the rotation of the pump (see
Figure 3B.3). Pump rotation should be counter-
clockwise when looking at the rear of the motor.
Directional arrows are located on each pump.
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
fi
lter
kits.
