", page 7!
• using the media listed under "
Correct Use Of
The Equipment
", page 7!
• at the values given under "
Technical Data",
page

WARNING
Hazard presented by negative pressure!
Hazard presented by moving parts!
• First connect the suction intake.
• Then check the connections and fasteners
have a tight fit and are sealed.
• And only then start up the system!
CAUTION
Risk of burns and scalds.
The system housing heats up to 85ºC under
normal operating conditions, especially around
the extracted air vent (pos.
9, page 3).
• wear gloves.
7.1 Starting up the system
• Switch on the power supply.
• The system begins to suck in the gases / va-
pours.
7.2 Switching off the system
DANGER
Electrical hazard!
The system is still live for a period of at least 3
minutes following disconnection of the power
supply.
• Before carrying out any work on the system
make sure that it is de-energized.
Make sure that the plant's working processes
allow the operation of the system to be inter-
rupted.
The system can be switched off from every oper-
ating condition.
• Switch off the power supply.
• The system interrupts the suction of the gases
/ vapours.
If the system is to be shut down for a longer pe-
riod of time: chapter
8 Decommissioning the ma-
chine and shutting it down for a longer period of
time
, page 14.
7.3 System in normal operation
CAUTION
Risk of burns and scalds.
The system housing heats up to 85ºC under
normal operating conditions, especially around
the extracted air vent (pos.
9, page 3).
• wear gloves.
If the cooling air vent / in-line filter are ex-
tremely dirty, the surface temperature on the
housing can reach over 85ºC!
• Clean cooling air vent / in-line filter (see
page
14).
It is possible to run the system continuously at
maximum vacuum and/or minimum intake pres-
sure (against closed suction slide).

WARNING
Improper handling of the system can result
in serious or fatal injuries!
Have you read the safety notes in chapter
1
Safety, page 5 f.?
If not then you are not allowed to carry out any
work on or with the system!
WARNING
Risks of burns and scalding from hot sur-
faces on the unit.
• Before working on the unit, allow the system
to cool down for at least 30 min after shutting
it down!
When shut down for longer periods
from about 4 weeks) the system can:
•
remain connected to the plant,
•
be disconnected from the plant so that it can
be sent to store.
8.1 Storage conditions
To avoid damage when stored for some time, the
environment must be:
• dry,
• free of dust,
• subject to low oscillations (effective value for
the speed of oscillation v
eff
≤ 0.2 mm/s
[0.008"/sec]).
8.2 Commissioning after a long shutdown
period
Commissioning after a long shutdown period:
• Measuring the motor insulation resistance.
For values ≤ 1kΩ per volt measured voltage
dry the coil.
• For new systems:
-
Install the system (chapter 5, page 9).
• Start up the system (chapter
6, page 12).
DANGER
Electrical hazard!

• First ventilate the feed lines (relieve pres-
sure).
• And only then work on the system!
WARNING
Improper handling of the system can result
in serious or fatal injuries!
Dismantle the system only after it has been
taken out of commission and has come to a
