In the T-installation, the pump is installed in a vertical position in a dry well next to the wet
sump. These requirements and instructions only apply when the installation is made
according to the dimensional drawing.
In the Z-installation, the pump is installed in a horizontal position on a support stand in a
dry well next to the wet sump, and a bell-mouth is connected to the inlet pipe. These
requirements and instructions are for Z-installations that comply to the dimensional
drawing.
Figure 6: T-installation
Figure 7: Z-installation
These items are required:
• Support stand and anchor bolts for anchoring the pump to a base
• Inlet elbow for connecting the suction line and discharge line
• Shut-off valves that allow you to remove the pump from service
• Air vent on the discharge side between the pump and the check valve
• Level regulators or other control equipment for start, stop, and alarm
NOTICE:
The risk of freezing is particularly high in T- or Z-installations.
1. Fasten the pump:
a) Use the anchor bolts to bolt the support stand to the concrete base.
b) Bolt the pump to the support stand and the suction connection.
2. Make sure that the pump is vertical for the T-installation or horizontal for the Z-
installation.
3. Connect the suction line and discharge line.
4. Connect the motor cable and the starter and monitoring equipment according to the
separate instructions.
Make sure that the impeller rotation is correct. For more information, see Check the
impeller rotation (page 37).
5. Make sure that the weight of the pump does not put strain on the piping.
