Always coordinate repair activity with operations and health and safety personnel, and follow all plant safety requirements and applicable safety and health laws and regulations.
1.6.3 Safety action
This is a summary of conditions and actions to prevent injury to personnel and damage to the environment and to equipment. For products used in potentially explosive atmospheres section 1.6.4 also applies.
NEVER DO MAINTENANCE WORK
WHEN THE UNIT IS CONNECTED TO POWER
GUARDS MUST NOT BE REMOVED WHILE
THE PUMP IS OPERATIONAL
DRAIN THE PUMP AND ISOLATE PIPEWORK BEFORE DISMANTLING THE PUMP The appropriate safety precautions should be taken where the pumped liquids are hazardous.
FLUORO-ELASTOMERS (When fitted.) When a pump has experienced temperatures over 250 ºC (482 ºF), partial decomposition of fluoro­elastomers (example: Viton) will occur. In this condition these are extremely dangerous and skin contact must be avoided.
HANDLING COMPONENTS Many precision parts have sharp corners and the wearing of appropriate safety gloves and equipment is required when handling these components. To lift heavy pieces above 25 kg (55 lb) use a crane appropriate for the mass and in accordance with current local regulations.
THERMAL SHOCK Rapid changes in the temperature of the liquid within the pump can cause thermal shock, which can result in damage or breakage of components and should be avoided.
NEVER APPLY HEAT TO REMOVE IMPELLER Trapped lubricant or vapor could cause an explosion.
HOT (and cold) PARTS If hot or freezing components or auxiliary heating supplies can present a danger to operators and persons entering the immediate area action must be taken to avoid accidental contact. If complete protection is not possible, the machine access must be limited to maintenance staff only, with clear visual warnings and indicators to those entering the immediate area. Note: bearing housings must not be insulated and drive motors and bearings may be hot.
If the temperature is greater than 68 °C (155 °F) or below -5 °C (23 °F) in a restricted zone, or exceeds local regulations, action as above shall be taken.
HAZARDOUS LIQUIDS When the pump is handling hazardous liquids care must be taken to avoid exposure to the liquid by appropriate sitting of the pump, limiting personnel access and by operator training. If the liquid is flammable and/or explosive, strict safety procedures must be applied.
Gland packing must not be used when pumping hazardous liquids.

MEN USER INSTRUCTIONS ENGLISH 71576288 – 11-09
PREVENT EXCESSIVE EXTERNAL PIPE LOAD Do not use pump as a support for piping. Do not mount expansion joints, unless allowed by Flowserve in writing, so that their force, due to internal pressure, acts on the pump flange.
ENSURE CORRECT LUBRICATION (See section 5, Commissioning, startup, operation and shutdown.)
START THE PUMP WITH OUTLET VALVE PART OPENED (Unless otherwise instructed at a specific point in the User Instructions.)
This is recommended to minimize the risk of overloading and damaging the pump motor at full or zero flow. Pumps may be started with the valve further open only on installations where this situation cannot occur. Pump outlet valve shall may need to be adjusted to comply with the duty following the run-up process. (See section 5, Commissioning start-up, operation and shutdown.)
1.7 Nameplate and safety labels
1.7.1 Nameplate
For details of nameplate, see the Declaration of Conformity, or separate documentation included
with these User Instructions.
1.7.2 Safety labels
NEVER RUN THE PUMP DRY
INLET VALVES TO BE FULLY OPEN WHEN PUMP IS RUNNING Running the pump at zero flow or below the recommended minimum flow continuously will cause damage to the seal.
DO NOT RUN THE PUMP AT ABNORMALLY HIGH OR LOW FLOW RATES Operating at a flow rate higher than normal or at a flow rate with no backpressure on the pump may overload the motor and cause cavitations. Low flow rates may cause a reduction in pump/bearing life, overheating of the pump, instability and cavitations/vibration.
1.6.4 Preventing the build up of explosive mixtures
ENSURE PUMP IS PROPERLY FILLED AND VENTED AND DOES NOT RUN DRY.
Ensure pump and relevant suction and discharge pipeline system is totally filled with liquid at all times during the pump operation, so that an explosive atmosphere is prevented. In addition it is essential to make sure that seal chambers, auxiliary shaft seal systems and any heating and cooling systems are properly filled. If the operation of the system cannot avoid this condition the fitting of an appropriate dry run protection device is recommended (eg liquid detection or power monitor).
Oil lubricated units only:
1.8 Specific machine performance
For performance parameters see section 1.5, Duty conditions. When the contract requirement specifies
these to be incorporated into User Instructions these are included here. Where performance data has been supplied separately to the purchaser these should be obtained and retained with these User Instructions if required.

MEN USER INSTRUCTIONS ENGLISH 71576288 – 11-09
1.9 Noise level
Attention must be given to the exposure of personnel to the noise, and local legislation will define when guidance to personnel on noise limitation is required, and when noise exposure reduction is mandatory. This is typically 80 to 85 dBA.
The usual approach is to control the exposure time to the noise or to enclose the machine to reduce emitted sound. You may have already specified a limiting noise level when the equipment was ordered, however if no noise requirements were defined, then attention is drawn to the following table to give an indication of equipment noise level so that you can take the appropriate action in your plant.
Pump noise level is dependent on a number of operational factors, flow rate, pipework design and acoustic characteristics of the building, and so the values given are subject to a 3 dBA tolerance and cannot be guaranteed.
Similarly the motor noise assumed in the “pump and motor” noise is that typically expected from standard and high efficiency motors when on load directly driving the pump. Note that a motor driven by an inverter may show an increased noise at some speeds. If a pump unit only has been purchased for fitting with your own driver then the “pump only” noise levels in the table should be combined with the level for the driver obtained from the supplier. Consult Flowserve or a noise specialist if assistance is required in combining the values.
It is recommended that where exposure approaches the prescribed limit, then site noise measurements should be made. The values are in sound pressure level LpA at 1 m (3.3 ft) from the machine, for “free field conditions over a reflecting plane”.
For estimating sound power level LWA (re 1 pW) then add 17 dBA to the sound pressure value.
In areas where the staff has to intervene, remember that when the level of the sound pressure is:
Below 70 dBA: it is not necessary to take special
precautions.
Above 70 dBA: people working continuously in
the machine room must be supplied with protective devices against noise.
Below 85 dBA: no particular measures need to
be taken for casual visitors staying in the room during a limited period.
Above 85 dBA: the room must be considered as a dangerous area because of the noise and a warning sign must be fixed at each entry warning the people coming into the room, even for a short period, that they must wear hearing protection.
Above 105 dBA: special hearing protection adapted to this noise level and to the spectral noise components must be installed and a warning sign to this effect erected at each entry. The staff in the room must wear ear protection.
Make sure that the noise, which travels through the walls and windows, does not generate too high noise levels in the machine room's surroundings. In areas where the staff has to intervene, remember that when the level of the sound pressure is:
2 TRANSPORT AND STORAGE
2.1 Consignment receipt and unpacking
Immediately after receipt of the equipment it must be checked against the delivery and shipping documents for its completeness and that there has been no damage in transportation.
Note all reserves on the signed shipping note which is given back to the hauler. Later, claims cannot be accepted.
Check any crate, boxes and wrappings for any accessories or spare parts that may be packed separately with the equipment or attached to sidewalls of the box or equipment.
Each product has a unique serial number. Check that this number corresponds with that advised and always quotes this number in correspondence as well as when ordering spare parts or further accessories.
2.2 Handling
2.2.1 General instructions concerning handling
Boxes, crates, pallets or cartons may be unloaded using forklift vehicles or slings dependent on their size and construction.
To lift heavy pieces above 25 kg (55 lb), use a winch adapted to the mass and in accordance with the current local regulations.
To lift machines or pieces with one or several suspension rings, only use hooks and chains in compliance with the local regulations concerning safety. Never put cables, chains or ropes directly on or in the suspension rings. Cables, chains or lifting ropes must never present excessive bending.
Page 7 of 36
®
MEN USER INSTRUCTIONS ENGLISH 71576288 – 11-09
Never bend the lifting hooks, suspension rings, chains, etc., which should only be made to endure stresses within, calculated limits. Remember that the capacity of a lifting device decreases when the direction of the lifting force direction makes an angle with the device axis.
To increase the safety and the efficiency of the lifting device, all the lifting elements must be as perpendicular as possible. If necessary a lifting beam can be placed between the winch and the load.
When heavy pieces are lifted up, never stay or work under the load or in the area, which could be in the path of the load if it were to swing or fall away. Never leave a load hanging from a winch. The acceleration or the slowing-down of lifting equipment must stay in the safety limits for the staff.
A winch must be positioned in such a way that the load will be raised perpendicularly. Where possible necessary precautions must be taken to avoid the swing of the load, using for example two winches making approximately the same angle, below 30°, with the vertical.
2.2.2 Pump masses
The masses of the pumps bare end of shaft are shown on the nameplate.
All motors (for masses see the motor description plate) must be handled with a winch.
Motor pump unit
Bareshaft pump
For masses above 25 kg (55 lb), manual
handling is forbidden.
2.3 Lifting
2.3.1 Slinging of motor pumps units
Use handling means in accordance with motor pump unit mass mentioned on the CE plate. For the masses of the pumps bare end of shaft see table §
2.2.2 and nameplate.
To avoid distortion, the pump unit
should be lifted as shown.
Components weighing less than 25 kg (55 lb) can be handled manually following the correct actions and using the correct posture.
When handling always wear gloves, safety boots and an industrial safety helmet.
For masses above 25 kg (55 lb), manual handling is forbidden.
2.4 Storage
Store the pump in a clean, dry location away from vibration. Leave piping connection covers in place to keep dirt and other foreign material out of pump casing. Turn pump at intervals to prevent brinelling of the bearings and the seal faces, if fitted, from sticking.
Do not store pumps starting on the fan guard. The pump may be stored as above for up to 6
months. Consult Flowserve for preservative actions when a longer storage period is needed.

4 INSTALLATION
4.1 Location
The pump should be located to allow room for access, ventilation, maintenance and inspection with ample headroom for lifting and should be as close as practicable to the supply of liquid to be pumped, and to the venting system.
Disconnect the switching enclosure support from the pump support by removing the fastening bolts. The switching enclosure support must be off-set with respect to the pump motor base.
4.2 Foundation
There are many methods of installing pump units to their foundations. The correct method depends on the size of the pump unit, its location and noise vibration limitations. Non-compliance with the provision of correct foundation and installation may lead to failure of the pump and, as such, would be outside the terms of the warranty. The base plate should be mounted onto a firm foundation, either an appropriate thickness of quality concrete or sturdy steel framework. It should NOT be distorted or pulled down onto the surface of the foundation, but should be supported to maintain the original alignment.
Anchor bolts must be in accordance with the foot bolt holes. Use anchor bolts of accepted standards and sufficient to ensure safe fitting in the foundation. Particularly, this applies to individual plates where the anchor bolts have to withstand the driving torque.
Provide sufficient space in the foundation to accommodate the anchor bolts. If necessary, provide concrete risers.
4.2.1 Setting the base plate for anchoring
- Clean the foundation surface thoroughly.
- Put shims on the foundation surface (approx 20-25 mm thick), one on each side of the bolt hole (as an alternative, leveling screws can be used).
- Lay the base plate and level in both directions with extra shims. The base plate should be level to within
0.5 mm per 1 m.
If anchor bolts have been pre-cast in the foundation slightly tighten the anchor bolts. Otherwise let them hang in the foundation holes.
4.3 Grouting
4.3.1 Base plate grouting
Prepare the site for grouting. Before grouting clean the foundation surface thoroughly and provide external barriers as shown:
barriers
Prepare grouting product (concrete, resin) in accordance with manufacturers' instructions.
Page 11 of 36
®
MEN USER INSTRUCTIONS ENGLISH 71576288 – 11-09
Use grouting products with anti-shrinking components.
- To grout up to the required level. Polish surfaces. Take necessary precautions to avoid air bubbles.
- Lay-down the barrier, break external angles, and polish the different surfaces.
- After grout starts to cure, definitively tighten anchor bolts.
- Control the alignment such as described as follows:
4.4 Initial alignment
4.4.1 Coupling assembly
4.4.1.1 Thermal expansion
The pump and motor will normally have to be aligned at ambient temperature and should be corrected to allow for thermal expansion at operating temperature. In pump installations involving high liquid temperatures, the unit should be run at the actual operating temperature, shut down and the alignment checked immediately.
4.4.1.2 Alignment methods
Ensure pump and driver are isolated electrically; that the batteries and start-up shunt are disconnected and the half couplings are disconnected. Ensure that the pump piping, suction and discharge, is disconnected.
The alignment MUST be checked.
Although the pump will have been aligned at the factory it is most likely that this alignment will have been disturbed during transportation or handling. If necessary, align the motor to the pump, not the pump to the motor.
Alignment Parallelism and concentricity check
Operations to be carried out by
qualified FLOWSERVE employees only.
Check the alignment at three or four
points, before piping assembly.
with a rule with a comparator
Admissible margin for a motor with roller bearings: = 0.15 mm parallel checking = 0.1 mm angular checking
Angular checking:
with a sliding rule with a caliper gauge
The alignment will be definitive only
after piping connection (see § 4.5.1).
After alignment, the coupling protection cover
must be refitted. If necessary, improve the machine alignment:
Complete unit mounted on common base plate:
The machines are first aligned accurately in our workshops. Usually, any misalignment observed on­site is due to a wrong adjustment under the base plate (disturbed during transport or because of forces exerted by the piping). It is only necessary to rectify the adjustment under base plate. If it proves to be insufficient, modify the motor and/or the piping and pump adjustment.

The battery must be disconnected. The distance between the end of the pump shaft and the engine flywheel must be 380 mm ± 5 mm. The pump and diesel engine must be aligned once the cardan link is fitted between the pump shaft and the engine flywheel.
The maximum axial misalignment allowed between the pump and the engine flywheel shaft is 9 mm ±
4.5 mm on each side of the shaft used as a reference for alignment (see fig.1). All that is required to align the pump and engine drive shafts correctly is a measuring tape or ruler graded in millimeters.
Alignment is checked as indicated below:
1) See fig.2 Place the marking A/B engraved on the surface of the cardan link flange at the top in the vertical position (12 o’clock). Measure the distance X between the flange and the outside of the cardan shaft (point A). This distance must be 76 mm ± 3 mm. With the cardan in the same position as above, measure the distance Y between the flange and the outside of the cardan shaft (point B). This distance must be equal to the distance X ± 1mm.
2) See fig.3 Turn the cardan 90° and place markings C/D engraved on the surface of the cardan link flange at the top in the vertical position. Measure the distance X1 between the plate and outside of the cardan shaft (point A). This distance must be 78 mm ± 1 mm. With the cardan in the same position as above, measure the distance Y1 between the flange and outside of the cardan shaft (point B). This distance must be equal to the distance X1 ± 1mm.
Alignment is achieved by moving and/or shimming one or both of the elements.

4.5 Piping
Protective covers are fitted to the pipe connections to prevent foreign bodies entering during transportation and installation. Ensure that these covers are removed from the pump before connecting any pipes.
4.5.1 Suction and discharge piping
The dimensions of the pipes do not directly depend on suction and discharge diameters of the pump: a) First, choose a flow speed < 2 m/s at suction, and about 3 m/s at discharge. b) Take into account the available NPSH, which must be superior to the required NPSH of the pump.
Never use pump as a support for piping. Do not mount expansion joints in such a way that their force, due to internal pressure, may act on the pump flange.
Maximum forces and moments allowed on the pump flanges vary with the pump size and type. These external strains may cause misalignment, hot bearings, worn couplings, vibrations and the possible failure of the pump casing.

5.3 Starting the pump
5.3.1 Bring controls and preparation before the first starting and after each service call
Necessarily:
Check the tightening of the different plugs. Check that the gland lightly tightens the packing
rings.
Risk of seal ring overheating.
If a mechanical seal is fitted, refer to the
standard pump instructions.
5.3.2 Start the pump and diesel engine
This initial start-up of pump and diesel
engine may only be carried out by a qualified FLOWSERVE employee.
A noise protection helmet must be worn by all persons present in the vicinity.
Suction valves must be fully open when pump is running. Never run the pump dry, it will cause damage.
*Close the valve at discharge * Start up the diesel engine and check the discharge
pressure. If pressure is satisfactory, slowly OPEN the outlet
valve. Do not run the pump with the outlet valve closed
during initial start-up and after each maintenance intervention.
If NO pressure, or LOW pressure, STOP the pump. Refer to fault finding chart for fault diagnosis.
5.3.2.1 Starting the diesel engine
Initial start-up: * Start the plant at moderate speed with push buttons to emergency start-up position 1 or 2.
* Check that the oil pressure indicated on the switching enclosure pressure gauge complies with the values given in the engine manual. If the oil pressure indicated on the pressure gauge is low with respect to these instructions, place the switch in the “Off” position and stop the engine using the direct stop control indicated "STOP" located on the injection pump until the engine is entirely at standstill.
Check engine cooling system: * Check that the water in the primary cooling circuit is flowing freely (evacuation of lost water, discharge from heat exchanger), it must be possible to see and feel this flow.
* Water flow must be visibly unrestricted on the pump discharge side, with no shut-off elements incorporated. This discharge generally occurs at 35/45 °C.
* Cooling water flow-rate is limited by an adjustable throttle to obtain a flow-rate of approximately 30 liters/hour per kW.
* New circuits often contain impurities which may quickly clog the protection filter. If the raw water flow decreases, simply remove the filter and clean it until the circuit is clean. This operation is to be repeated.
* The manual by-pass on the cooling circuit main pipe is only used to ensure cooling, if necessary, when the plant cannot be shut-down during an intervention on the raw water filter or the hydraulic valve.
ENSURE THE RAW WATER FILTER ON THE MAIN COOLING CIRCUIT IS WEEKLY CLEANED.
Checks and adjustments: * Progressively increase the engine speed until the setting limiter is attained. This limiter is set to obtain an off-load speed of 50 to 100 rpm above nominal speed in order to compensate for approximately 5 % motor slip between off-load and full-load engine speeds.
* With the plant running normally, progressively open the pump discharge valve until the specified performance is attained.
* Check the water temperature with the thermostat on the switching enclosure; this is only attained progressively, especially at low pump flow-rate.
If the temperature is above 95 °C, turn the selector switch to “Off” and activate the switch-off control marked STOP.
In the beginning, when on load, the new plant sometimes emits exhaust smoke after start-up. This is perfectly normal and quickly disappears. Allow sufficient air circulation during initial start-up (work with doors open), and/or wear a protection mask.
The switching enclosure is designed to detect and signal certain anomalies.
When running: * Oil pressure too low * Overheating

MEN USER INSTRUCTIONS ENGLISH 71576288 – 11-09
If one of these faults occurs, the alarm is triggered and signaled by:
- activation of the siren;
- illumination of the corresponding indicator;
- repeated signal on the terminal for transmission.
However, a fault does not stop the plant. Immediate intervention is required to remedy the
fault.
- The siren may be switched off by pressing the push-button "STOP SIREN". This operation does not cancel the siren if the fault signal is present at the alarm terminal.
- Turning the rotary key switch "CANCEL FAULT" remains ineffective as long as the fault persists and resets the audible alarm signal.
Simulation of faults: The safety devices may be checked by simulating faults: a) Excess water temperature fault simulation by circuit opening between 55 wires and grounds. b) Oil pressure low by circuit opening between 35 and 56 wires. [No oil pressure by circuit opening between wires 035 and 56] if the engine is at standstill and by circuit closing (035 and 56) when the engine is running.
Water temperature fault function is activated only after an initial time period of approximately 10 seconds.
Oil pressure fault function is efficient only after an initial time period of approximately 1 minute.
Check room ventilation: Ensure that room ventilation is correct by incorporating top and bottom air vents as standard practice. These vents must each have a minimum size of 0.5 m².
Engine overheating is generally due to:
- defective engine and/or room cooling,
- an exhaust pipe of insufficient diameter,
- non-standard utilization of the plant, in excess of its design characteristics.
- insufficient room ventilation The temperature read on the thermometer located
on the front panel of the switching enclosure must be stable between 70 and 90 °C when the plant is on-load and conform to nominal characteristics indicated in the specifications.
If the cooling water temperature rises above this threshold value, an audible alarm is triggered and a light indicator switches on.
Do not run the pump at zero flow-rate for more than 10 minutes as this will heat up the cooling water intended to cool the engine.
After approximately one hour of operation, the plant may be switched off by pressing the control button marked STOP.
ACTION MAINTAINED UNTIL TOTAL STANDSTILL OF THE ENGINE.
Automatic start-up pressure switch n °1 : With the selector pressure switch n° 1 in the "AUTO" position and selector pressure switch n° 2 on stop, the contact given by one of the control pressure switches provokes immediate start-up of the plant at the set nominal speed.
* Supervision of start-up sequence The engine should normally start up first time.
However, to overcome an anomaly such as:
- Low batteries, pump packing gland too tight
- No fuel
- Slight presence of air in the fuel circuit
- Engine and room insufficiently heated during cold weather
The automatic system is designed to energize the starter motor with 8-second impulses from each set of batteries alternatively.
The standard setting is 4 impulses of 8 seconds with a rest period of 3 seconds between each impulse. At the end of a complete cycle, if the engine has not started, the alarm "FAIL START" is triggered, followed by:
- Activation of the siren
- Illumination of the "Fail start" indicator
- Repeated signal at the terminals for transmission. The operator informed may attempt a manual start
by pressing the "EMERGENCY START" push­button.
Automatic start-up pressure switch n °2: Same automatic start-up procedure with pressure switch n °1 but in the reversed order.
* Simulation of a start-up sequence It can be done by any of both selector pressure switch n °1 and n° 2.
The first pressure switch contact to be opened will initiate its start-up sequence. To check the start-up sequence, a simulation may be carried out in which the injection is blocked by pressing and holding the stop control while the plant is in "AUTO" mode and the contact of a pressure switch is closed (pressure drop in the network).

MEN USER INSTRUCTIONS ENGLISH 71576288 – 11-09
NOTE: The "FAIL START" alarm is cancelled by:
- Pressing the "STOP SIREN" push-button
- Pressing the "CANCEL FAULT" turn-key switch This operation also resets the automatic cycle.
All pressure switches have a differential pressure. The contact triggered by a drop in pressure is only re-established when this pressure returns to a value greater than the pressure switch set value.
Battery fault: At standstill: The plant comprises a starter battery voltage­monitoring device. If the battery voltage is not in the required range, the battery fault is triggered, followed by:
- illumination of the corresponding indicator for battery 1 or battery 2,
- repeated signal on the terminals for transmission. However, the plant continues to operate on the other
battery. Technical room temperature control (optional):
A technical room temperature inferior to + 10 °C lights up the "TEMPERATURE LOCAL SPRINKLER" red LED and activates the siren and the "FAILURE RISK" relay.
The siren can be stopped by pressing the "STOP SIREN" pushbutton. But this does not clear the fault which is reported on the alarm base station.

5.3.2.2 Putting into service:
After completion of these checks and tests, the plant may be put into service:
- Turn the selector switch to the "AUTO" position
- Valves of the cooling circuit locked in the open position and the discharge valve of the pump positioned.
- Check all fill levels.
- Power-on displayed with light indicator.
5.3.2.3 Plant maintenance and servicing:
Once a week, check the voltage and electrolyte level of each battery; the water level of the internal cooling circuit, the engine oil fuel tank levels.
Respect all instructions given in the pump and engine manuals, as well as the regulations R1 given in appendix IV of the APSAD.
Do not run the pump with the outlet valve closed for a period longer than 10 minutes.
If NO pressure, or LOW pressure, STOP the pump. Refer to fault finding chart for fault diagnosis.
The pump must never run at a capacity of less than 40 % of that at the best efficiency for a longer period.
5.4.1 Pump fitted with a stuffing box
If the pump has a packed gland there must be some leakage from the gland. Gland nuts should initially be finger-tight only. Leakage should take place soon after the stuffing box is pressurized. If no leakage takes place the packing will begin to overheat. If overheating takes place the pump should be stopped and allowed to cool before being re-started. When the pump is re-started it should be checked to ensure leakage is taking place at the packed gland.
The pump should be run for ten minutes with steady leakage and the gland nuts tightened by 10 degrees at a time until leakage is reduced a steady thin continuous stream is acceptable. The temperature of the gland should be checked after each round of tightening. If the temperature starts to climb rapidly then back off the gland nuts at standstill until the temperature drops down. Wait for the temperature to stabilize before tightening again. The leakage must not be reduced below a rate of 60 drops per minute. Bedding in of the packing may take several hours.
Never remove a plug when the pump is running.
The pump should run smoothly and without abnormal vibration for a diesel engine.
5.4 Running the pump
Never remove the exhaust heat screens. The combustion engine may attain a temperature of
80 °C during operation and up to 450 °C at the exhaust pipe. Specific instructions must be sign­posted to inform all persons present of the risk of burns.
Inspections by the operator: * The pressure gauge on the switching enclosure indicates the oil pressure in the diesel engine block: if the pressure gauge indicates a pressure lower than that designated by the red arrow on the dial, the engine must be stopped immediately by switching the selector switch to stop and moving the stop lever on the diesel engine.
* The thermometer on the switching enclosure indicates the diesel engine cooling water temperature: if the thermometer indicates a temperature higher than that designated by the red arrow on the dial, the engine must be stopped immediately using the same procedure as indicated above.
The engine may only be restarted by an employee qualified by FLOWSERVE.
Shield grids being removed during installation of the gland packing, it must be ensured that they are replaced as soon as this operation is completed.
SAFETY INSTRUCTIONS WHEN THE PUMP IS RUNNING.
If hot or freezing components of the machine can present a danger to operators, they must be shielded to avoid accidental contact. If a 100 % protection is not possible, the machine access must be confined to the maintenance staff only.
If the temperature is greater than 80 °C, a warning plate must be clearly placed on the pump.
Check that the gland lightly tightens the packing rings.
Risk of seal ring overheating.
After examination of the packing gland, DO NOT FORGETS TO REFIT THE BEARING PROTECTION SCREENS.

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.
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.

INSPECTIONS AND PRECAUTIONS
- As the plant can start up automatically at any time and therefore represents a potential source of danger, it must be placed in a room reserved exclusively for this purpose with sufficient space and lighting and a lockable door. Access must be restricted to properly trained and authorized staff.
- Due to the noise generated by the diesel engine, as well as the risk of splashing or burning, protective goggles, gloves and ear protection are obligatory. In the case of new equipment, or when excessive oil vapor is emitted, a protection mask should be worn if ventilation is insufficient. Do not touch the exhaust pipe, turbo-compressors or any moving parts. In the case of burns or scalds, always seek medical attention.
- The motor-pump unit must only be used for fire-fighting purposes.
- The concrete base supporting the motor-pump unit must be correctly dimensioned and manufactured in order to bear the static and dynamic loads of the unit. In the case of visible cracks the base will need to be repaired.
- Ensure that air inlets and ventilation are present, correctly dimensioned (min. 0.5 m² each) and
are not blocked (nests).
- The supply of fresh air and evacuation of heat generated by the engine require an adequate air intake and ventilation system in order to ensure that fresh air circulates through the room and the diesel engine is provided with the air required for combustion.
- The room must not be humid, plan for sufficient ventilation and heating. If the equipment is subjected to a high level of humidity for several days, check the electrical switching enclosure and replace all components which may be damaged (electronic card, chargers, etc…) with original spare parts.
- Opening of the ventilation flaps when the motor-pump unit is running and ensuring they are not blocked is essential for correct operation. If these flaps are closed or blocked, the engine will draw in hot air with subsequent loss of power and risk of internal overheating.
- The room must be kept at a temperature of more than 10 °C. Check that the heater functions correctly.
- Remove traces of rust or oxidation from the power supply and battery terminals and coat with
- Start the plant as indicated in the instructions, carry out the tests required and take note of all personal safety warnings and indications.
- All abnormal leakages must be monitored and the engine dealer contacted.
- Check that there is no visible damage and ensure all light indicators on the switching enclosure are green. Also check the room heating system and water pressure values if the equipment is supplied from the town water supply.

x x
x
- In case of a prolonged power supply shutdown, carry out a booster charge of the batteries or chargers. A full test must be carried out.
- Ensure the primer tank contact is perfectly connected or the terminal rail shunt if this contact is not used.
- Clean pipes and filters after working on the water supply circuit.

- Clean the filter after each test.
- Check that the water flows correctly after the heat-exchanger, the hydraulically-controlled valve is correctly opened and all hydraulic connections are in a good state of repair.
- Check the coolant level with the engine switched off and cold. Opening the cap when the engine is hot could result in severe scalding due to splashing liquid. Always seek medical attention immediately in such a case.
- Check the oil level with the engine switched off and cold before each test. The oil contributes towards the heat exchange process and provides lubrication.
- Check that the exhaust pipe is not blocked (nests) and it is protected against the entry of rain water.
- Pay attention to parts subjected to vibrations (turbo-compressor, filters, exhaust, pipes, etc…) as the tightness of these elements may vary. If parts are not securely fastened, remedy the problem or contact the manufacturer’s agent. Special attention must be given to the manual stoppage system which must slide effortlessly and must not remain blocked in the stop position.
- Check for leaks or retighten the injectors. If the diesel supply or return pipes are removed, ensure they have not been accidentally switched.
- The oil filters must be replaced once a year.
- The diesel tank must be topped up with fuel compliant with the engine specifications. Special
attention must be paid to ensure there is no water present in the system. If this is the case, the tank and pipes will need to be drained, rinsed and flushed out immediately.
- The fuel filters must be replaced at least once a year.
- If the engine runs out of fuel or the fuel system is disconnected, flush the entire fuel circuit as indicated in the engine instructions.
- The air filters must be replaced at least once a year.
- Check the drive belts and replace them if the slightest traces of wear or aging are noted, otherwise, replace them every 2 years.
- Check the engine manufacturer’s documentation for major maintenance work required (tappets, valves, head gasket, etc…) to be carried out at least once a year.
- Check that the batteries charge and the electrolyte level every week (top up with distilled water when necessary) and ensure the batteries are replaced once a year.
- Always check that the re-heater functions correctly before starting the engine (the engine temperature must be higher than 20 °C). Replace the re-heating element every year (we recommend the storage of spare parts, a thermostat and a heating element for maintenance purposes).

-
The heating element must be disconnected when the coolant is drained and the engine
flushed before reconnecting.
- Check the vibration and temperature levels regularly. In case of a problem, contact the engine manufacturer’s dealer.
- Check alignment of couplings regularly and at least once a year.
- A slight leak is imperative around the packing gland to guarantee lubrication and cooling of the seals (refer to the corresponding pages in the instructions for possible adjustment).
- Oil leaks around certain component seals are possible: this is due to dilatations. These leaks must be wiped away to avoid soiling of the equipment.
- The room must be kept clean at all times; clean away all stains and check their origin.
- Do not store inflammable materials in the engine room (with the exception of approved fuel supplies) and keep the room locked.
- An annual servicing is obligatory. It must be carried out by a qualified technician approved by FLOWSERVE.
- The hydraulic hose between the heat-exchanger supply circuit and the heat-exchanger must be replaced every 5 years.
- The fuel hydraulic hoses (supply and Return) must be replaced every 5 years.

6.2.2 Gland packing
6.2.2.1 Pump fitted with a packed gland
A well run in and correctly adjusted packing gland requires little maintenance. If, after some time, the leakage becomes too great, the gland should be tightened again in order to return these to a normal level.
If re-tightening is not possible, new packing must be installed
6.2.2.2 Gland packing inspection and removal
a) Remove the shield guards b) Slide back the gland c) Remove the packing rings with an extractor designed for this purpose (including the lantern ring if it exists; note its position and its direction of rotation). d) Inspect the state of the sleeve surface (except for ME-TI and MEN-TI pumps); the presence of many marked grooves will indicate that it must be replaced. e) Carefully clean the different pieces of the packing gland.

MEN USER INSTRUCTIONS ENGLISH 71576288 – 11-09
6.2.2.3 Gland packing fitting
If the packing is supplied as cord the packing must be cut so that the external diameter is lightly tightened and there is an initial gap between the sleeve and the packing ring.
For that purpose, wind the packing helically around the shaft sleeve or a chuck of the same diameter. (Take precautions to avoid damaging sleeve).
Ensure a tightening on the stuffing
box housing and not on the sleeve.
Setting of packing
Follow the instructions: a) Assemble of the packing in S.
b) Stagger by about 90° between two rings. c) Assemble packing after packing.
After setting the last packing, fix the gland on the packing and screw up the nut by hand.
After this screwing phase, the shaft should turn by hand as easily as before the setting of the packing.
