8.2 Preparations before commissioning
The actions below are valid for applications with flooded suction
conditions.
1. Check that all screws are tight.
2. Check that all pipes and hoses are installed correctly.
3. Check all electrical connections.
4. Check that all fuses in the control cabinet are switched on.
5. Check the alignment of the coupling. See section
6. Check that the coupling guard is installed correctly and that all
screws are tightened to 10 Nm for M6 and 25 Nm for M8.
7. Check that all safety devices are installed.
8. Make sure that any storage tank (5 and 6) and pump priming
tank (7) are filled with water.
9. Set the pressure switches according to the instructions.
System pressure minus 0.5 bar can be used as a reference
value.
10. Open the isolating valves on the suction and discharge sides.
The static geometric suction pressure from the main water
tank will fill the suction pipe, discharge pipe and pump with
water.
11. Close the isolating valves on both the suction and discharge
side.
8.2.1 Pump set with diesel engine
1. Check the V-belt tension.
2. Check the oil level and refill, if necessary.
3. Check the level of coolant and refill, if necessary.
4. Check that all hose connections in the cooling circuit are tight
and leakage-free.
5. Fill the fuel tank with diesel fuel and vent the fuel pipes.
8.3 Starting the pump set
Additional safety instructions for pump set with diesel
engine
General procedure
1. Open the isolating valve on the suction side.
2. Check that the isolating valve on the discharge side is closed.
3. Open the isolating valve of the test pipe (10).
4. Switch on the controller (4) and start the pump (1a).
See installation and operating instructions for the controller.
5. Slowly open the isolating valve on the discharge side of the
pump.
6. When the pump reaches operating pressure, open the
isolating valve sufficiently to reach the duty point.
7. Measure and read the relevant operating parameters and
compare them with the rated values.
8. Stop the pump via the controller and set the pump set to
automatic mode. See installation and operating instructions
for the controller.
9. Close the isolating valve of the test pipe (10).
10. Check that the isolating valve at the discharge side is fully
open.
The pump set is now operational and in automatic mode.
Caution
Check the level of oil and coolant in the engine
prior to startup.
Note
See installation and operating instructions for
the diesel engine.
Warning
Some pump sets have a sound pressure level
higher than 70 dB(A). See page 31. In these
cases, wear hearing protection when the pump
set is running.
Note
Observe the safety instructions in the installation
and operating instructions of the individual
components.
Note
See also installation and operating instructions
for the controller and diesel engine.
Warning
Remove the fuel canisters from the room before
starting the pump set.
Warning
Fuel vapours are flammable. Do not start the
engine if there are fuel vapours in the room.
Warning
Exhaust must be directed safely to the open air
through the exhaust system.
Exhaust must not escape indoors.
Operation without an exhaust system is not safe.
Warning
The pump set must not be started without a
coupling guard.
Warning
Make sure that persons cannot accidentally come
into contact with hot exhaust pipes.
Note
Open the fuel valve on the fuel tank and vent the
fuel system. See installation and operating
instructions for the diesel engine.
Warning
Fuel escaping under pressure can penetrate the
skin and cause serious injuries. Always release
the pressure before disconnecting the fuel pipes.
Repressurise when the pipes have been
tightened.
Warning
When the pump set is primed, pressurized and
the engine is started, check the pump set for any
kind of leakage of oil, water or fuel.
Warning
When the engine is started, check for exhaust
leakage and abnormal noise level.
Stop the engine immediately if the exhaust
system is leaking.
Note
Collect excess fuel in a container and dispose of
it in accordance with local regulations.
Note
If the pump does not start, see the fault
indications on the controller and section
13. Fault finding.
