4.3 Startup
Before installation and the first startup of the pump, check the
condition of the cables visually to avoid short circuits.
Proceed as follows:
1. Lock the mains switch in position 0.
2. Check the oil level in the oil chamber.
See section
.
3. Check that the impeller can rotate freely.
4. Check whether the monitoring units, if used, are operating
satisfactorily.
5. Open the isolation valves, if fitted.
6.
Pumps in installation types S and C:
Ensure visually that
the pump is properly connected to the auto coupling.
7. Make sure that the pump is submerged in the liquid.
8.
Pumps in installation types D and H:
Make sure that there
is liquid in the pit and that the pump housing and cooling
jacket are filled with water. Open the air vent screw on top of
the cooling jacket, pos. 9 in fig.
, before or during the
startup until water comes out. Then close the screw.
Pumps in installation type ST:
Make sure that the pump is
properly seated in the column pipe and secured against
rotation of the complete pump.
9. Start the pump, and check the pump operation for abnormal
noise or vibrations.
10. After startup, establish the actual pump duty point as
accurately as possible so that you can check whether the
operating conditions are as desired.
Always operate the pump in accordance with established routines
with scheduled checks of pump monitoring equipment and
accessories, such as valves, etc. Make sure that the pump and
equipment settings cannot be changed by unauthorised persons.
5. Handling and storing the product
5.1 Handling the product
Before handling the product, check the following points:
• Lifting equipment and lifting points
See section
• Raising pump to upright position.
See section
3.1.2 Raising the pump to upright position
• Move pump only with fork-lift or with lifting crane.
5.2 Storing the product
For long periods of storage, that is six months or longer, the pump
must be protected against moisture and heat.
After a long period of storage, that is six months or longer, inspect
the pump before putting it into operation. Make sure that the
impeller can rotate freely.
Pay special attention to the condition of the shaft seals, O-rings
and the cable entries.
In case of abnormal noise or
vibrations from the pump, or other
pump or liquid supply failures,
stop the pump immediately. Do
not attempt to restart the pump
until the cause of the fault has
been found and the fault
corrected.
DANGER
Crushing hazard
Death or serious personal injury
- Make sure the centre of gravity
is between the fork-lift arms
when lifting the pump.
Leave the cable end protectors
on the power supply and sensor
cables until you start making the
electrical connection. Whether
insulated or not, the free cable
ends must never be exposed to
moisture or water.
Non-compliance with this may
cause damage to the motor.
If the pump is being stored for
more than two months, turn the
impeller by hand at least every
two months to prevent the seal
faces of the lower mechanical
shaft seal from seizing up.
If you do not do this, the shaft
seal may be damaged when the
pump is started.
If the impeller cannot be turned
by hand, contact an authorized
service workshop.
For dry-installed pumps, make
sure the cooling jacket is empty
before storing the pump.
