Installation (pictures
to
For operating and installation follow any relevant national
standards that are in operation.
1. The vacuum connection (A) is situated on the angle flange (S).
All pipes and tanks which are to be connected onto the vacuum
side, must be cleaned before use.
Long and/or small bore pipework should be avoided as this
tends to reduce the capacity of the pump.
If the suction pipe is longer than 5 m, then a larger diameter than
that of the pump flange should be used.
If solid particles or liquids are to be handled, additional separators
(Z
/Z
) must be fitted in the suction pipe.

2. Exhaust port (B)
If an exhaust pipe is connected directly at (B) it is advisable to make
sure that this pipe is fitted in such a way that there is a permanent
decline away from the pump. If a climbing pipe has to be used, a
condensate trap (Z

condensate.
If an oil mist separator (Z
) is used, the exhaust pipe can be connected

directly onto this unit.
The exhaust port (B) must not be obstructed or partly ob-
scured.
3. The lubricating oil (recommended brands see under servicing) can be
put into the pump at the oil filler port (H) of the oil tank, until the oil level
shows at the upper mark of the oil sight glass (l). After filling make sure
the oil filler port is closed.
4. The electrical data can be found on the data plate (N) or the motor data
plate. The motors correspond to DIN/VDE 0530 and have IP 54
protection and insulation class B or F. The connection diagram can be
found in the terminal box on the motor (unless a special plug connec-
tion is fitted). Check the electrical data of the motor for compatibility
with your available supply (voltage, frequency, permissible current
etc.).
5. Connect the motor via a motor starter. It is advisable to use thermal
overload motor starters to protect the motor and wiring. All cabling
used on starters should be secured with good quality cable clamps.
We recommend the use of a motor starter with thermal and magnetic
overload protection. A tempory overload may occur during a cold start.
The electrical installation may only be made by a qualified
electrician under the observance of EN 60204. The main switch
must be provided by the operator.
6. Operation
When handling wet or aggressive gases, a valve (Z
Additionally, the pump must be operated for approximately 20 to 30 minutes, before and after the vacuum process. This allows the cold pump
to reach operating temperature before the process has begun, which avoids condensation within the pump. When the process is finished, the
pump will then be flushed with fresh oil, which clears contamination within the pump and preserves simultaneously, for the standstill. During this
running before and after the process, the valve (Z
must be turned anticlockwise a few revolutions.
Initial Operation (picture
)
1. Initially, switch the pump on and off for a few seconds to check the direction of rotation against the direction arrow (O).
2. Connect the suction pipe at (A).
Potential risks for operating personnel
1. Noise Emission: The worst noise levels considering direction and intensity measured according to DIN 45635 part 3 (as per 3. GSGV) are shown
in the table at the back. When working permanently in the vicinity of an operating pump we recommend wearing ear protection to avoid any damage
to hearing.
2. Oil mist in the Exhaust Stream: Even with the high efficiency oil mist separator (optional extra) the exhausted air could still contain extremely low
amounts of oil mist which can occasionally be detected by smell. Permanent breathing of these mists may result in health problems, therefore
it is extremely important to make sure that the installation area is well ventilated.
3. Poisonous or hazardous substances in the Exhaust Stream: When the pump is used for
chemical processes, poisonous or hazardous materials can be exhausted. Therefore, it is
necessary to route them via a scrubbing system.
