Operation
DANGER
Electrical danger!
Before beginning work on the unit or system,
the following measures must be carried out:
•
Deenergize.
•
Secure against being switched on again.
•
Determine whether deenergized.
•
Ground and short-circuit.
•
Cover or block off adjacent energized parts.
Check operating speeds:
Observe the operating speed specified on the
rating plate. This may not be exceeded, as
otherwise the noise radiation, vibration
behavior, grease consumption duration and
bearing change interval worsen. To prevent
damage as a result of higher speeds, it may be
necessary to inquire with the Service
Department as to the maximum speed.
WARNING
Danger of hearing damage due to noise
radiation!
For the noise emission of the pump-motor unit
measured by the manufacturer, see Chapter 3.1,
"Mechanical data", Section "Noise level", Pg. 7.
However, the actual noise emission during
operation is highly dependent on the
installation and system conditions.
Conduct a noise measurement in the system
during operation after installing the pump-
motor unit.
The following measures must be taken by the
operator:
•
from 85 dB(A):
–
Hearing protection must be provided.
•
from 90 dB(A):
–
Mark noise area with a warning sign.
–
Wear hearing protection.
–
With free entry and exit of gases, i.e.
with direct intake out of or direct feeding
into the atmosphere without piping,
attach an additional muffler.

Starting up and shutting down
See Chapter 6, "Commissioning", Sub-
Chapter 6.2, "Start-up and shut-down", Pg. 19.
Also be sure to observe the following important
notes especially for operation:
WARNING
Danger of burns from hot surfaces of the
pump-motor unit and from hot fluids!
High temperatures of up to approx. 160 °C
[320 °F] can occur on the surface of the pump-
motor unit.
Do not touch during operation!
Allow to cool after shut-down!
CAUTION
Danger of overheating due to hot surface of
pump-motor unit!
High temperatures of up to approx. 160 °C
[320 °F] can occur on the surface of the pump-
motor unit.
Temperature sensitive parts, such as lines or
electronic components, may not come into
contact with the surface of the pump-motor
unit.
CAUTION
Danger of overheating!
During operation the standstill heating may, if
installed,
not
be switched on!
CAUTION
Danger of rusting due to collection of
condensed water in drive motor area!
On drive motors with closed condensed water
openings:
Remove closures occasionally to allow any
water which has collected to drain off.
