Dekker Vacuum Technologies, Inc. – DuraVane/12 8
START-UP PROCEDURES
1
DuraVane rotary vane vacuum pumps and
systems are shipped from the factory dry. They
do not contain oil. A container of Duratex oil is
shipped with the unit. Before operating add the
supplied oil to the pump(s). Fill the pump(s) to
the middle of the sight glass before start-up.
MAX
MIN
2
Completely close the inlet suction valve before
starting the unit.
3
Jog the motor briefly (press START then
STOP) and check direction of rotation which is
marked by an arrow on the end of the motor or
pump housing. If the direction is backwards,
switch any two of the three leads at the power
connection. A loud grinding noise and absence
of vacuum is an indication of improper motor
direction.
WARNING: OPERATING PUMP BACKWARD
CAN CAUSE VANE FAILURE.
4
Start and run the unit for approximately five (5)
minutes, then stop.
5
With the unit shut off, check the oil level again.
The oil level should be visible in the middle of
the bulls-eye gauge. Add oil if necessary.
WARNING: NEVER REMOVE THE OIL FILL
PLUG WHILE THE VACUUM PUMP SYSTEM
IS RUNNING.

6
Start the unit and adjust the inlet suction valve
to your desired vacuum setting. Check that the
discharge pressure does not exceed 2 psig
when operating above 15” HgV. A pressure
higher than 2 psig at start-up is a sign of high
backpressure in the discharge pipe system. As
the running time of the pump(s) increases the
backpressure will increase.
7
Voltage and motor current should be checked
by a qualified electrician and should be within
the motor specifications.
Note: This test should also be performed under
normal system operating conditions.
DANGER: HIGH VOLTAGE!
Lethal shock hazard present.
USE EXTREME CAUTION!
