4.2 Description
The V-VTE model range are complete with a pipe connection on the inlet and an exhaust silencer on the outlet.
All the air handled is fi ltered by a built-in micro-fi ne fi lter. The motor fan cools the motor and pump housing.
Both the motor and pump have a common shaft.
4.3 Areas of application
These dry running rotary vane vacuum pumps V-VTE 3 to V-VTE 10 are suitable for evacuating closed systems and for a permanent vacuum in the intake pressure range 150 - 1000 mbars (abs.).
The pumping capacity with unrestricted suction is
3.5, 6, 8 and 10 m3/h at 50 Hz. Data sheet D 187 shows
the dependency of the pumping capacity on the intake pressure.
These dry running machines are suitable for conveying air with a relative humidity of 30 - 90%.
If the unit is switched on more frequently (at regular intervals of about 10 times an hour) or at
higher ambient temperatures and intake temperatures, the excess temperature limit of the motor
winding and the bearings may be exceeded.
Please contact the manufacturer should the unit be used under such conditions.
If it is installed in the open air the unit must be protected from environmental infl uences, (e.g. by a
protective roof).

5.1 Preparing for installation
Check the following points:
• Machine freely accessible from all sides
• Do not close ventilation grids and holes
• Suffi cient room for installing and removing pipes
and for maintenance work, particularly for installing and dismantling the machine
• No external vibration effect
• Do not suck any hot exhaust air from other machines into the cooling system.
There must be a minimum space of 20 cm in front of the housing cover (
The cooling air entries (Fig. 1/E) and the cooling air exits (Fig. 1/F) must have a minimum distance
of 8 cm from any obstruction. The discharged cooling air must not be recirculated.
5.2 Installation
Ensure that the foundation complies with the follow-

5.3 Connecting pipes
a) Vacuum connection at (Fig. 1/A).
The air handled can be exhausted into the atmosphere through the exhaust port (Fig. 1/B) or
by utilising a pipe connection and pipeline.
NOTICE
The pumping capacity of the vacuum pump is
reduced if the suction pipe is too narrow and/or
too long.
5.4 Control and relief valve (optional extra)
The vacuum can be set by turning the control knob
(Fig. 1/C) as shown on the symbol fi tted to the button.

Installation
5.5 Connecting the motor
DANGER
Danger of death if the electrical installation has
not been done professionally.
The electrical installation must only be done by a
qualifi ed electrician observing EN 60204. The operating company has to provide the main switch.
a) The electrical motor data can be found on the
data plate (Fig. 1/N) or the motor data plate
(Fig. 1/P
). The motors comply with DIN EN
1
60034 and are in protection class IP 55 and
insulation class F. The appropriate connection
diagram is located in the motor‘s terminal box
(not for the plug connection version). The motor
data must be compared with the data of the
existing mains network (current type, voltage,
network frequency, permitted current value).
b) Connect the motor via the plug connection or
a motor protection switch (for safety reasons a
motor protection switch is required and cable
fi tting must be provided to provide strain relief
for the connection cable). We recommend using
motor protection switches with delayed switch
off, depending on possible excess current.
Temporary excess current may occur when the
machine is started cold.
NOTICE
Power supply
The conditions at the installation location must match
the information on the motor data plate. Without
derating the following is permissible:
• ± 5% voltage deviation
• ± 2% Frequency deviation

6.1 Commissioning
Commissioning and decommissioning
WARNING
Improper use
May lead to severe or fatal injuries. Therefore be
sure to obey the safety instructions.
CAUTION
Hot surfaces
When the machine is at operating temperature the
surface temperatures on the components (Fig. 1/
Q) may go above 70°C.
You must avoid touching the hot surfaces (marked
with warning plates).
CAUTION
Noise emission
The highest noise pressure levels measured as per
EN ISO 3744 are given in Section 9.
When spending a long time in the vicinity of the
running machine use ear protectors to avoid permanent damage to your hearing.
NOTICE
Wait until the machine stops
The machine must only be switched on again after
it stops.

Commissioning and decommissioning
6.1.1 Checking the rotation direction
The drive shaft direction of rotation is shown by
the rotation direction arrow (Fig. 1/O).
a) Start the motor briefl y (max. two seconds) to
check the direction of rotation. When looking at
the motor fan, it must rotate clockwise.
The suction pipe must not be connected
when starting up like this.
NOTICE
Incorrect direction of rotation
Running the machine in reverse for a long time may
cause damage to the blades which may lead to the
blades breaking. Use a phase sequence indicator
to check the direction of rotation (anti-clockwise
rotating fi eld).
6.2 Decommissioning/ storing
Stop the machine
a) Switch the machine off.

Maintenance and repair
DANGER
Danger of death from touching live parts.
Before maintenance work disconnect the machine
by pressing the main switch or unplugging it and
ensure that it cannot be turned on again.
WARNING
Hot surfaces
During maintenance work there is the danger of
getting burnt on hot components (Fig. 1/Q).
Wait for the machine to cool down.
7.1 Ensuring operational safety
Regular maintenance work must be carried out in order to ensure operational safety.
Maintenance intervals also depend on the operational demands on the machine.
With any work observe the safety instructions described in Section 2.8 “Safety notes for installation, com-
missioning and maintenance”.
The whole unit should always be kept in a clean condition.
7.2 Maintenance work
Interval Maintenance to be carried out Section
monthly Check the pipes and screws for leaks and to ensure they are
—
seated properly and if necessary seal again or tighten up.
monthly Check the terminal box and cable inlet holes for leaks and if
—
necessary re-seal.
monthly Clean the ventilation slots on the machine and the motor
—
cooling ribs.
—
The machine‘s bearings are permanently lubricated and do
—
not require re-lubricating.
monthly / yearly Clean or replace fi lter cartridges 7.2.1
4,000 h - 1,000 h Check blades
Replace blades 7.2.2

NOTICE
Insuffi cient maintenance on the air fi lter
The power of the machine lessens and damage may
occur to the machine.
The fi lter cartridge (Fig. 3/f) air must be cleaned by
blowing from the inside to the outside once a month
or more often depending on the level of contamination, or if necessary replaced.
In spite of cleaning the filters their separation efficiency will continue to deteriorate.
Therefore the fi lters should be replaced every year
(or under extreme condition more often).
Changing fi lters:
Screw off housing cover (b).
Remove fi lter cartridge (Fig.
3/f) with gaskets (Fig. 3/
m, 3/n) from fi lter room (Fig. 3/g). Clean or replace
fi lter cartridge and check gaskets.
Reassemble in reverse order.
a) Don’t interchange gaskets (Fig. 3/m, 3/n)
b) Ensure that the surfaces of housing (Fig. 3/d)
c) Tighten the screws (Fig. 3/s) to 5,5 + 0,5 Nm

7.2.2 Replacing blades
WARNING
Danger of injury when dealing with compressed air.
When blowing through with compressed air, solid
particles may be carried along or powder dust swirling around may cause injury to the eyes. Therefore,
when cleaning with compressed air always wear
goggles and a dust mask.

Checking blades:
The models V-VTE have 4 blades which have a low
but permanent wear factor.
First check after 4,000 operating hours, thereafter
every 1,000 operating hours.
Unscrew the housing cover (Fig. 3/b) from the housing. Remove the blades (Fig. 7/e) to be checked. All
blades must have a minimum height (Fig. 3/X):
Type X (minimum height)
V-VTE 3, 6 10 mm
V-VTE 8, 10 12 mm
The blades must only be changed as a set.
Changing blades: If you detect during the blade
check that the minimum height has been reached or
it has fallen below the minimum height, the blade set
must be changed.
Blow out the housing and the rotor slot. Insert the
blades into the rotor slot. When doing this you must
ensure that the blades with the sloping side (Fig. 3/
Y) point outwards and the direction of rotation of
these sloping sides (Fig. 3/O1) matches that of the
drilled holes for the housing (Fig. 3/Z).
Replace the housing cover (Fig. 3/b) and slightly
tighten the screws. Start the pump briefl y and check
for free and smooth running blades. Tighten the
screws (Fig. 3/s) to 5,5 + 0,5 Nm.
