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 casing 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 neither sharply bent, nor 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) Thread the level regulator cable through the holes in the cable holder, and adjust
the height of the level regulators.
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 access 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 equipment according to
the separate instructions.
Make sure that the impeller rotation is correct. For more information, see
Check the
impeller rotation (page 29).
Clean all debris from the sump before starting the pump.
Install with S-installation
In the S-installation, the pump is transportable and intended 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.
