5. Starting up the product

Before the first startup and after a long standstill
period, make sure that the pump has been filled with
FM
pumped liquid.
Proceed as follows:
1. Remove the fuses or switch off the main switch.
2. Check the motor liquid level in the cooling chamber. See
section
8.1.1 Checking the motor
3. Check whether the impeller can rotate freely.
4. Check whether the monitoring units, if used, are operating
satisfactorily.
5. For pumps in submerged installation, make sure that the
pump is submerged in the liquid.
6. For pumps in dry installation, make sure that there is liquid in
the pit from which the supply of pumped liquid comes.
Make sure that the pump has been filled with
pumped liquid.
FM Pumps in dry installation must be vented via the vent
hole in the pump housing.
Dry running is not allowed
7. Open the isolating valves, if fitted.
8. Check whether the system has been filled with liquid and
vented.
9. Check the setting of the level switches.
10. Start the pump and check the pump operation for abnormal
noise or vibrations.
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.
11. After startup, the actual pump duty point must be established
as accurately as possible so that it can be checked whether
the operating conditions are as desired.
The pump may only be started for a very short period
without being submerged for checking of direction of
rotation.
Always operate the pump in accordance with established routines
and scheduled checks of pump monitoring equipment and
accessories, such as valves. Make sure that the pump and
equipment settings cannot be changed by unauthorized persons.

6. Handling and storing the product

6.1 Handling the product

Before handling the product, check the following points:
• Lifting equipment and lifting points.
See section
4.1.1 Lifting the pump.

6.2 Storing the product

Leave the cable end protectors on the power and
control cables until you start making the electrical
connection. Whether insulated or not, the free cable
end must never be exposed to moisture or water.
Non-compliance with this may cause damage to the
motor.
For periods of storage, six months or longer, the pump must be
protected against moisture and heat.
liquid.
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, installation types D and H,
make sure the cooling jacket is empty before storing
the pump.
After a period of storage, 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 entry.
