These items are required:
• Guide bars
• Guide bar bracket for attaching the guide equipment to the access
frame or to the upper part of the sump
• Level regulators or other control equipment for start, stop, and
alarm
• Cable holder for holding the cable and regulating the height of the
level regulators
• Access frame (with covers) to which the upper guide bar bracket
and cable holder can be attached
• Discharge connection for connecting the pump to the discharge
line
The discharge connection has a flange which fits the pump housing
flange and a bracket for attaching the guide equipment.
• Fasteners for the discharge connection
• Anchor bolts
1. Run a cable between the sump and the stator and monitoring
equipment.
Make sure that the cable is not sharply bent or pinched.
2. Install the access frame:
a) Place the access frame in position and align it horizontally.
b) Grout the frame in place.
3. Grout the anchor bolts in place.
Be careful when you align and position the discharge connection in
relation to the access frame.
4. Place the discharge connection in position, and tighten the nuts.
5. Install the guide bars:
a) Secure the guide bars in the bracket.
b) Check that the guide bars are placed vertically. Use a level or a
plumb line.
6. Connect the discharge pipe to the discharge connection.
7. Prepare for the level regulator:
a) Bolt the cable holder to the access frame.
b) Attach the level regulator cable to the cable holder and adjust
the height of the level regulator.
c) Protect bolts and nuts with a corrosion-preventive compound.
8. Lower the pump along the guide bars.
9. Secure the motor cable:
a) Fasten the permanent lifting device to the pump and to the ac-
cess frame. For example, you can use a stainless-steel lifting
chain with shackles.
b) Fasten the cable to the cable holder.
Make sure that the cable cannot be sucked into the pump inlet
or that it is neither sharply bent, or pinched. Support straps are
required for deep installations.
c) Connect the motor cable and the starter and monitoring equip-
ment according to the separate instructions.
Make sure that the impeller rotation is correct. For more infor-
mation, see Check the impeller rotation on page 13.
Clean all debris from the sump before starting the pump.
4.1.3 Install with Free-standing installation
In the Free-standing installation, the pump is transportable and intend-
ed to operate either completely or partially submerged in the pumped
liquid. The pump is equipped with a connection for hose or pipe and
stands on a base stand.
The stand is integrated with the pump housing and the hose is con-
nected to pump using thread coupling.
These requirements and instructions only apply when the installation is
made according to the dimensional drawing.

Figure 3: Free-standing installation
1. Run the cable so that it has no sharp bends. Make sure that it is not
pinched, and cannot be sucked into the pump inlet.
2. Connect the discharge line.
3. Lower the pump into the sump.
4. Place the pump on the base and make sure it cannot fall over or
sink.
Alternatively, the pump can be suspended with a lifting chain just
above the sump bottom. Make sure that the pump cannot rotate at
startup or during operation.
5. 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 informa-
tion, see Check the impeller rotation on page 13.
