Open all suction valves.
Close the discharge valve.
Check that all suction pipes, as well as the pump
itself, are correctly filled before switching on the
pump.
It is strictly forbidden to open switch cupboards,
switch boxes, or all other live electric equipment. If it
is necessary to open them in order to take readings,
to carry out tests or adjustments for example, only a
skilled technician may do them with adapted tools.
Make sure that physical protection against electrical
risks is used.
Preparation of the diesel engine:
Take note of and respect the instructions relative to
commissioning of the diesel engine in the engine
instructions enclosed.
These operations may be carried out by personnel
qualified by FLOWSERVE only.
For information:
The fuel tank (diesel) must be filled by the installer
beforehand.
Smoking or naked flames are strictly forbidden
during the fuel filling operation. Recommended fuel
type: ASTM-D975-N° 2, DIN 51601, SIS 155432,
"vehicle fuel".
a) Fill the cooler with cooling fluid and flush all air
out of the internal circuit.
Add antifreeze as indicated in the engine instruction
manual in order to protect the engine in case of an
excessively low temperature in the power station
and to avoid corrosion inside the motor.
b) Check the engine oil level.
c) Flush the fuel circuit. If the circuit is not correctly
flushed, the engine may not start up.
5.5 Stopping and switching off
Close the discharge valve and limit pump operation
to maximum 10 minutes with the valve closed.
Stop:
By manually turning the shut-off control, marked
"STOP", to the "STOP" position.
For prolonged shut-downs and especially when
ambient temperatures are likely to drop below
freezing point, the pump and any cooling and
flushing arrangements must be drained or otherwise
protected. The APSAD regulations require a
constant room temperature of minimum 10 °C in the
pumping station.
To restart, refer to § 5.3 and 6.2.
The following emergency measures must be
taken whenever the equipment is shut down:
- ensure that persons and equipment are
protected by applying the pre-defined
procedures together with the health and safety
department.
- have the work carried out by properly trained
and competent staff.
6 MAINTENANCE
6.1 General
It is the plant operator's responsibility to
ensure that all maintenance, inspection and
assembly work is carried out by authorized and
qualified personnel who have adequately
familiarized themselves with the subject matter by
studying this manual in detail (see also section
1.6.2).
Any work on the machine must be performed when it
is at a standstill. It is imperative that the procedure
for shutting down the machine is followed.
On completion of work all guards and safety devices
must be re-installed and made operative again.
Before restarting the machine, the relevant
instructions listed in section 5, Commissioning, start
up, operation and shut down must be observed.
Emergency start-up
As required by the APSAD regulations, the plant
may be started by pressing the red emergency start
button(s) on the switching enclosure, regardless of
the other switching enclosure controls.
In order to ensure safety during service
interventions, the storage batteries must be
disconnected.
Oil and grease leaks may make the ground
slippery. Machine maintenance must always
begin and finish by cleaning the ground and the
exterior of the machine.
If platforms, stairs and guardrails are required for
maintenance, they must be placed for easy access
to areas where maintenance and inspection are to
be carried out. The positioning of these accessories
must not limit access or hinder the lifting of the part
to be serviced.
When air or compressed inert gas is used in the
maintenance process, the operator and anyone in
the vicinity must be careful and have the appropriate
protection. DO NOT SPRAY air or compressed inert
gas on skin. DO NOT DIRECT an air or gas jet
towards other people. Never use air or compressed
inert gas to clean clothes.
