Pump set with electric motor
Check the direction of rotation. The correct direction of rotation is
indicated by an arrow on the pump. If the direction is wrong,
interchange two phases of the power supply.
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 cooling liquid and refill, if necessary.
4. Check that all hose connections of the cooling circuit are tight
and leakage-free.
5. Fill the fuel tank with diesel fuel and vent the fuel pipes.
12.2 Starting the pump set
Additional safety instructions for pump set with diesel
engine
General procedure
1. Open the isolating valve on the suction side of the pump.
2. Close the isolating valve on the discharge side of the pump.
3. Open the isolating valve of the test pipe.

4. Switch on the controller and start the pump. See installation
and operating instructions for the controller.
5. Slowly open the isolating valve on the discharge side of the
pump. Loosen the vent plug in the pump housing (pump with
electric motor), see fig. 28, or in the discharge pipe (pump with
diesel engine). As soon as liquid escapes, tighten the air vent
screw to 25 Nm (1/2") or 30 Nm (3/8"). Torques apply to plugs
in the pump housing. When the pump reaches operating
pressure, open the isolating valve sufficiently to reach the duty
point.
6. Measure and read the relevant operating parameters and
compare them with the rated values.
7. Stop the pump via the controller and set the pump set to
automatic mode. See installation and operating instructions for
the controller.
8. Close the isolating valve of the test pipe.
The pump set is now operational and in automatic mode.
12.3 Checking the function
In connection with start-up, a final test run must be carried out
according to the standard applying to the pump set. Activate the
automatic start-up command by lowering the pressure in the
discharge pipe with a closed fuel valve. Lower the pressure by
opening the isolating valve of the test pipe.
Every starting cycle consists of a starting phase followed by a
pause. After six failed start attempts, a start failure warning must
be activated. When the fuel cock has been opened and the fault
indication has been removed, the pump should start properly.
12.4 Shaft seal run-in
The seal faces are lubricated by the pumped liquid, meaning that
there may be a certain amount of leakage from the shaft seal.
When the pump is started up for the first time, or when a new
shaft seal is installed, a certain run-in period is required before
the leakage is reduced to an acceptable level. The time required
for this depends on the operating conditions, i.e. every time the
operating conditions change, a new run-in period will be started.
Under normal conditions, the leaking liquid will evaporate. As a
result, no leakage will be detected.
Caution
Do not start the pump to check the direction of
rotation until it has been filled with water and
vented. Let the pump run only for a short period.
Caution
Check the level of oil and cooling liquid in the
engine prior to start-up.
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 section 8.2 Pump set.
In these cases, wear hearing protection when the
pump 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 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 gases must be directed safely to the
open air through the exhaust system.
Exhaust fumes must not escape indoors.
Operation without an exhaust system is not safe.
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 pipes have been tightened.
Note
Collect excess fuel in a vessel and dispose it in
accordance with local regulations.
Note
If the pump does not start, see the fault
indications on the controller and section
16. Fault finding.
Note
This section applies to pump sets with diesel
engine.
