Setup and connection
5 Setup and connection
NOTE
Material damage due to distortion or passage of electrical
current in the bearing!
Do not make any structural modi fi 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!
Do not remove the transport seals until immediately before
setting up the pump.
Do not remove any covers or transport and sealing covers
until immediately before connecting the pipes to the pump.
5.1 Preparing the setup
5.1.1 Check operating conditions
1. Ensure the required operating conditions are met:
– Resistance of body and seal material to the medium
(
→ resistance lists).
– Required ambient conditions
(
→ 9.2.1 Ambient conditions, Page 26).
2. Ensure necessary dimensions for tank cut-out ( → Data
sheet).
3. Ensure safe aeration and venting of the container in all
operating phases.
4. Ensure required installation dimensions and fi lling lev-
els ( → 9.2.6 Installation dimensions and fi lling heights,
Page 27).
–
Minimum distances
– Maximum fi lling height
– Minimum fi lling height
5.1.2 Preparing the installation site
Ensure the installation site meets the following conditions:
–
Pump is freely accessible from all sides
– Suf fi cient space for the installation/removal of the pipes
and for maintenance and repair work, especially for the
removal and installation of the pump and the motor
– Pump not exposed to external vibrations (damage to
bearings)
– Frost protection
5.1.3 Surface preparation
Aids, tools, materials:
–
Spirit level
1. Make sure the surface meets the following conditions:
– 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
2. Clean containers, basins or pits carefully and protect from
further contamination, e.g. by installing over fl ow wall in
front of the container or pit inlet.
5.2 Setting up
1. Remove the suction-side cover if present.
2. Lift pump/pump assembly (
→ 4.1 Transport, Page 9 ).
3. Place pump/pump assembly on the contact surface of the
container/pit.
4. Attach sole plate to the contact surface.
– Pump must not be mechanically under tension as a
result of being attached
5. Screw on the sole plate ( → 9.2.4 Sole plate tightening
torques, Page 26).
