5 Setup and connection
NOTE
Material damage due to distortion or passage of electrical
current in the bearing!
Do not make any structural modi ¿ cations to the pump
assembly or pump casing.
Do not carry out any welding work on the pump assembly
or pump casing.
NOTE
Material damage caused by dirt!

5.1 Preparing for installation
5.1.1 Checking the operating conditions for the ETLB-S
Fig. 4 Mounting the ETLB-S pump on containers
(example with suction extension)
1. Ensure the required operating conditions are met:
– Resistance of body and seal material to the medium
(
ĺ Resistance lists).
– Required ambient conditions
( ĺ 9.2.1 Ambient conditions, Page 31).
2. Ensure necessary dimensions for tank cut-out ( ĺ data
sheet).
3. Ensure safe aeration and venting of the container in all
operating phases.
4. Ensure the required installation dimensions and ¿ lling lev-
els are satis ¿ ed ( ĺ data sheet).
– Minimum distances
– Maximum ¿ lling height
– Minimum ¿ lling height

1. Ensure the required operating conditions are met:
– Resistance of body and seal material to the medium
(
ĺ resistance lists).
– Required ambient conditions
( ĺ 9.2.1 Ambient conditions, Page 31).
2. Provide an appropriate supporting structure with the
required dimensions for the pump support
(
ĺ data sheet). Guarantee the following conditions for the
supporting structure:
–
Level and horizontal
– Clean (no oil, dust or other impurities)
– Capable of bearing the weight of the pump assembly
and all operating forces
– Stability of the pump ensured
– Resonance-free
3. Ensure safe aeration and venting of the container in all
operating phases.
4. Ensure the required installation dimensions and ¿ lling lev-
els are satis ¿ ed ( ĺ data sheet).
– Minimum distances
– Maximum ¿ lling height
– Minimum ¿ lling height
5. Clean containers, basins or pits carefully and protect from
further contamination, e.g. by installing an over À ow con-
tainment wall in front of the container or pit inlet.
