6.2 PREPARATORY ACTIVITIES
6.2.1 FILL IN OIL
ATTENTION
The pump is delivered without oil. Before commissioning, oil must first be filled in.
NOTE
For information on oil types and filling quantities, see chapter 9.3.
1. Unscrew the screw plug (Pos.3) at the top or side of the oil tank.
2. Fill in oil. The oil level must not exceed the max. filling level (upper filling line next to the oil sight glass
(item 12)).
3. Close the screw plug again
6.2.2 CONNECTING THE MEDIA LINES
WARNING
When installing high temperature media lines, be sure to cover, insulate and label them appropriately to
prevent injury and pump damage.
WARNING
Low residual amounts of oil in the exhaust air.
Ensure that the rooms are adequately ventilated to minimise any possible health risk to people.
ATTENTION
Penetration of foreign bodies or liquids
Depending on the application and the associated air quality, a fine or coarse filter must be connected
upstream of the pump.
Remove sealing plug
The suction connection (Pos.7) is protected against the ingress of dirt and foreign bodies for transport with a
sealing plug. This must be removed before commissioning.
Dimensioning the suction line
The diameter of the suction line depends on the pump size and the line length.
There is a female thread in the connection flange. Use cables with a diameter at least equal to the nominal
connection diameter of the connection flange according to the following table.
