4.2.5 Installing the column pipe
1. Fit a waterproof sealing between the mounting flange and the
concrete support. See fig. 14.
Fig. 14 Position of the waterproof sealing
2. Slowly lower the column pipe into the pit using overhead lifting
equipment.
3. Make sure that the column pipe is vertical and fastened to the
concrete.
4. Tighten the anchor bolt nuts to ensure that the column pipe
cannot move.
4.2.6 Installing the KPL and KWM pump
Make sure that the pump is aligned with the anti-rotation brackets
and cannot rotate when the impeller runs.
1. Make sure that the sealing O-ring is clean and located in the
groove on the bottom of the inlet casing (KPL) or outlet casing
(KWM). The O-ring seals between the pump and the seat ring
to preventing backflow.
2. Slowly lower the pump into the column pipe using the
overhead lifting equipment. If necessary, use an intermediate
lifting ring.
3. Carefully guide the pump into position at the bottom of the
column pipe, so the pump does not tilt in any way on the stop
vanes at the bottom of the column pipe.
4. Lift the pump 1 inch (2 to 3 cm) and turn it counter-clockwise
until the anti-rotation brackets touch the nearest adjacent stop
vanes.
4.2.7 Installing the cable suspension system in the column
pipe
Follow these instructions and secure the cables properly:
1. Clamp the wire rope and all cables together. Make sure there
is 20 inches (0.5 m) distance between the clamps adapted to
the weight of the cables. See fig. 15.Fasten the wire rope to
the eye at the top of the column pipe.
2. Adjust the turnbuckle between the wire rope and the eye of
the beam. Make sure there is no slack in the cable
suspension, the cables are fixed to it and cannot move during
operation.
3. Lead the cables through the cable bushing of the column pipe.
4. Run the cables to the external terminal box. Make sure that
the cable bushing is fitted correctly and prevents water from
entering.
5. Fit the top cover on the upper part of the column pipe using a
waterproof gasket, then tighten the bolts. Make sure that the
cover prevents water from entering.
TM05 5307 3612
Wrong direction of rotation results in damage to the
pump.
- Check the direction of rotation before the
installation. See section 5.1.1 Checking the
direction of rotation.
- The use of a phase detection equipment, such as
the MP 204, protects the pump from starting if the
phase sequency is changed.
The pump is secured by its own weight against the
anti-rotation brackets. No additional fastening is
required.
Turbulence optimization is not possible if the pump is
mounted in an oversize column pipe.
Waterproof
sealing
If the pump is configured for side discharge, locate
the cable inlet opposite the water outlet.
Disruption in the direction of water flow may cause
damage to the cable.
To avoid cable damage, do not position the cable
inlet in the column pipe near the water outlet.

4.5 Frequency converter operation
All KPL, KPG and KWM pumps can be connected to a frequency
converter if an output filter is installed between the converter and
the motor. In case a filter is not installed, please contact
Grundfos.
Pumps can be connected ideally to a Grundfos CUE, - or a soft
starter, depending on choice.
When pumps are connected to a frequency converter pay
attention to the motor insulation system.
The minimum frequency depends on the type of application and
the design of the discharge piping. Always consider the following
when determining the minimum frequency:
• mass of the water above the propeller
• the force required to keep valves open
• the velocity reaction forces.
These factors vary from case to case. The minimum frequency
has to produce the necessary torque and force from the impeller
and propeller to overcome the above mentioned factors.
In environments with high content of sand, for example water
treatment plants, a self-cleaning velocity of at least 1 m/s must be
ensured in the column's largest diameter.

5. Starting up the product
The pump can be started by either direct-on-line starting, star-
delta starting, soft starter or frequency converter. For the wiring of
the start-stop circuit, see fig. 22 or 23.
Fig. 22 Direct-on-line starting
Fig. 23 Star-delta starting
5.1 Preparations for starting up
• Turn the propeller or impeller by hand to make sure the
propeller or impeller can rotate freely. See fig. 25.
• Make sure that the supply voltage and frequency correspond
to the values stated on the nameplate. If not, do not start the
pump.
• Make sure that the outer cable sheath is intact, so water
cannot penetrate to the terminal box. If the original power
cables are refitted, cut off a short piece to ensure that the
cable entry sealing sleeve does not clamp around the cable.
• Make sure that the cable entry bushing and the washers
correspond to the outside diameter of the power cables. When
preparing the power cable conductors for connection to the
pump and the terminal box, ensure that the ground (earth)
conductor is at least 2.2 inches (50 mm) longer than the other
conductors. This is substantialin case a cable is pulled out
unintentionally, so the ground (earth) conductor connection is
the last to be disconnected.
• Check the direction of the rotation. See section 5.1.1 Checking
the direction of rotation.

5.1.1 Checking the direction of rotation
Check the direction of rotation before the startup.
Method 1 - Free-standing pump
Proceed as follows:
1. Place the pump on a plain surface.
2. Secure the pump by using the lifting chain and a crane to
preventit from tilting. The pump must rest on the ground
without any load on the crane. See fig. 24.
Fig. 24 Pump secured with a crane
3. Start the pump and let it run for a few seconds.
4. Observe the jerk of the pump. If the pump jerks
counterclockwise, the direction of rotation is correct. See fig.
25.
If the direction of rotation is wrong, interchange two phases in the
power cable.
Method 2 - Pump installed in a column pipe
• Make sure the column pipe is not filled with water.
• Make sure the pump is installed correctly. See section
4.2.6 Installing the KPL and KWM pump.
Proceed as follows:
1. Check the electrical connections with a phase detector to
make sure the connections are correct.
2. Start the pump and let it run for a few seconds.
3. Observe the jerk of the pump. If the pump jerks
counterclockwise, the direction of rotation is correct. See fig.
25.
If the direction of rotation is wrong, interchange two phases in the
power cable.

DANGER
Electric shock
Death or serious personal injury
- In case the pump is running with wrong direction of
rotation, do not touch the pump or the cables.
KPL and KWM: Wrong direction of rotation leads to
damage to the pump and the column pipe.
Always check the direction of rotation before the pipe
is filled with liquid.
DANGER
Crushing hazard
Death or serious personal injury
- Never stand under or next to the pump when it is
hanging from a crane.

5.2 Startup
Proceed as follows:
1. Lock the main switch in position 0.
2. Check the oil level in the oil chamber.
3. Make sure that the monitoring units are operating
appropriately.
4. Make sure that the pump is submerged in the liquid.
5. Open the isolating valves, if fitted.
6. Check the setting of the level switches.
7. Unlock the main switch, start the pump and check the pump
operation for abnormal noise or vibrations.
When started, the pump jerks counterclockwise.
8. After startup, establish the actual pump duty point.
6. Handling and storing the product
6.1 Handling the product
• Make sure that the lifting equipment is appropriate.
See section 4.2 Lifting the product.
• Always lift the pump by its lifting bracket/eye or by a forklift
truck, if the pump is fixed on a pallet.
• Observe the maximum cable bending radius. See
12.2.1 Bending radius of cables.
6.2 Storing the product
For periods of storage, the pump must be protected against
moisture and heat. After a period of storage, inspect the pump
before putting it back into operation. See also section
12.1.8 Storage temperature.
6.2.1 Storing in the pit (dry or wet)
The pump is frost-proof as long as it is operating or submerged in
the liquid. If the pit has been pumped dry, and the pump has been
exposed to the atmosphere, allow the pump to stand submerged
in the liquid for a short period before starting it up. This eliminates
the possibility of a frozen propeller or impeller. Never use an open
flame to thaw out the pump.
If the pump is submerged in liquid, operate it for 30 seconds
every month.
6.2.2 Storing in dry conditions
During storage, pay attention to the condition of the shaft seals
and the cable entries. Clean the pump at regular intervals and
spray it with corrosion-inhibiting oil. Always store the pump
protected and do not exposeit to direct sunlight.
DANGER
Automatic startup
Death or serious personal injury
- Before manual starting or changeover to automatic
control, make sure that no persons are working on
or near the pump.
Do not start the pump before checking the direction
of rotation.
Always operate the pump in accordance with
established routines with scheduled checks. Ensure
that the pump and equipment settings cannot be
changed by unauthorized persons.
In case of abnormal noise or vibrations, stop the
pump immediately. Do not restart the pump until the
cause of the fault is identified and eliminated.
Leave the cable end protectors and sensor cables on
the power until making the electrical connection.
The free cable ends must never be exposed to
moisture or water.
If the pump is stored dry, rotate the propeller or
impeller by hand at least bi-monthy to prevent the
shaft seals from seizing up.
If the propeller or impeller cannot be turned by hand,
contact an authorized service workshop.
