    (a) With the pump room door(s) closed, and the pump testing technician present. (i) RUN the pumpset at shut-off (zero flow) for 10 min to allow all equipment to attain normal operating temperature. (ii) RUN the pumpset at the most hydraulically favourable duty point (sprinklers) or at 130% of duty flow (hydrants) for 10 min and record the result. Flow ... L/min @ pressure ...... kPa (iii) Reduce the flow to the most hydraulically unfavourable duty point for sufficient time to record the water supply proving test results. Flow ... L/min @ pressure ...... kPa (iv) Further reduce the flow until shut-off (zero flow) is achieved and continue to run the pumpset until total run time has reached 30 min. During this period RECORD the following for Items (ii), (iii) and (iv) above: (A) Suction pressures. ................... kPa (B) Discharge pressure. ................... kPa (C) Engine running temperature. ..................... °C (D) Engine oil pressure. ................... kPa (E) Air temperature at the engine intake manifold. ..................... °C (F) Engine r/min, using both installed tachometer and calibrated tachometer. Record variations. ................. r/min While carrying out the above procedures, CHECK temperature of bearings and stuffing box leakage and note and report any abnormality. NOTE: If the pump room temperature rises more than 10°C above ambient temperature, this could indicate inadequate ventilation and possible reduction in engine power. ................. r/min ................. r/min variation Action required and pass/fail requirement (b) SIMULATE an engine fail to start and ensure that engine-start cycling requirements and alarm activations are satisfied. (c) TEST correct operation of pump priming tanks and associated equipment, where fitted.

    (a) With the pump room door(s) closed and the pump testing technician present: (i) RUN the pumpset at shut-off (zero flow) for 3 min. (ii) RUN the pumpset at the most hydraulically favourable duty point (for sprinklers) or 130% of duty flow (for hydrants) for 4 min and record the results. (iii) Reduce the flow to the most hydraulically unfavourable duty point (for sprinklers) or duty flow (for hydrants) for sufficient time to record the water supply, proving test results. (iv) Further reduce the flow until shut-off (zero flow) is achieved and continue to run the pumpset until total run time has reached 10 min. During this period RECORD the following for Items (ii), (iii) and (iv) above: (A) Suction pressure. ................... kPa (B) Discharge pressure. ................... kPa (C) Air temperature at the electric motor. ..................... °C (D) Motor rpm. ................. r/min (E) Amps (all three phases).

    (a) REPLACE engine oil with new oil that meets the engine manufacturer’s specification. More frequent oil changes shall be carried out if recommended by the engine manufacturer. (b) REPLACE engine oil filter and fuel filters and, if required, air filters. (c) CHECK the condition of the fuel. NOTE: Visually check a sample of the fuel for foreign particles, contamination, fungal growth, appropriate smell and colour, etc. If suspect, report, replace or send the sample to an independent testing agent. (d) INSPECT engine cooling hoses and replace where necessary. (e) FLUSH engine cooling system and refill using manufacturer’s approved corrosion inhibitor (water-cooled engines only). (f) PRESSURE TEST engine cooling system in accordance with the manufacturer’s recommendations (radiator and heat exchanger cooled engines only). (g) CHECK correct operation of the engine cooling system pressure-reducing valves, where fitted. (h) REMOVE and CLEAN or REPLACE heat exchanger strainer(s). (i) CARRY out any other routine service procedures in accordance with the engine manufacturer’s requirements. (j) INSPECT pump/driver coupling for wear and alignment. Replace worn or damaged components. (k) GREASE jump bearings to the manufacturer’s specifications where greased nipples are provided. (l) Where the pump bearings are of the oillubricated type, REPLACE the bearing oil with new oil that meets the pump manufacturer’s specification (does not apply to turbine type vertical shaft centrifugal pumps). (m) REPLACE the oil in right-angle gearboxes with new oil that meets the manufacturer’s specification.

    With all electrical equipment isolated from all power supplies: (a) INSPECT the condition of all exposed heavy current-carrying contacts. Report any item showing any signs of wear or corrosion. (b) INSPECT pump/driver coupling for wear and alignment. Report worn or damaged components. (c) Where grease nipples are provided, GREASE pump and motor bearings to the manufacturer’s specifications. (d) Where the pump bearings are of the oillubricated type, REPLACE the bearing oil with new oil that meets the pump manufacturer’s specification (does not apply to turbine type vertical shaft centrifugal pumps).

    CHECK that the system pressure relief valve opens and closes at the pressure stated on the pressure gauge schedule. NOTE: Inappropriate settings for pressure-relief valves can result in very large quantities of water flowing to waste. Ensure settings are maintained to have pressures as high as allowed by system component rated working pressures. Operating pressure ...... kPa
